Daycare centers, schools, colleges, and universities place special demands on ventilation systems. Many people are present at the same time in classrooms, group rooms, or seminar rooms, while actual occupancy can fluctuate significantly throughout the day.

A suitable air-handling concept must therefore combine good indoor air quality with energy efficiency, low noise levels, and demand-based operation. At the same time, buildings vary considerably: from a single group room in a daycare center to classrooms, large lecture halls, and extensive university buildings.

AHUs can vary accordingly. Decentralized units for individual rooms, compact solutions for building sections, and central AHUs for entire buildings may be appropriate, depending on the project.

Why is indoor air quality particularly important in educational institutions?

In heavily occupied rooms, indoor air quality changes rapidly. Among other things, people release carbon dioxide (CO₂), moisture, and heat into the indoor air. Without sufficient air exchange, the CO₂ concentration in particular rises continuously while the space is in use.

Ventilation must therefore provide sufficient outdoor air while simultaneously taking other indoor loads into account. In addition to CO₂, factors such as temperature, humidity, odors, and usage-related pollutants can be relevant to indoor air quality.

Mechanical ventilation enables predictable air exchange regardless of whether windows are opened regularly. The required airflow rate can be adjusted to the use and occupancy of the respective area.

Why is demand-controlled ventilation beneficial?

Educational buildings are rarely used everywhere at the same time and with the same number of people. A classroom may be fully occupied, while the adjacent room stands empty. Seminar rooms and lecture halls sometimes experience even greater fluctuations in occupancy.

If the ventilation system were operated continuously at maximum airflow regardless of these factors, an unnecessarily large volume of air would have to be moved, heated, or cooled. Demand-based control, on the other hand, can adjust the airflow to actual demand.

Depending on the use, control variables can include, for example, CO₂ concentration, room temperature, humidity, occupancy, or time-based schedules. This ensures that only as much air is treated and transported as is required for the respective use.

We explain more about the interaction between sensors, DDC, and demand-based control in the section on AHU control technology.

How important is sound insulation?

Teaching, supervision, and focused work place high demands on the acoustic conditions of a room. Noise from the ventilation system should therefore be taken into account from the very beginning of the planning process.

The fan in the AHU is not the only decisive factor here. Air velocities, ductwork, silencers, air diffusers, and the installation location all influence the perceived noise in the room.

For decentralized units installed directly in or adjacent to the occupied space, the unit’s acoustics take on particular importance. In centralized systems, the spatial separation of the air-handling unit can offer additional opportunities for noise reduction.

Centralized or decentralized—which ventilation concept is best?

For educational and childcare facilities, there is no single suitable ventilation concept. The right solution depends, among other things, on building size, room layout, available technical spaces, airflow rates, and the options for duct routing.

Central AHUs can serve multiple rooms, sections of a building, or an entire building. This allows air treatment, heat recovery, filtration, and control to be consolidated centrally.

Floor-by-floor or zone-based solutions offer a middle ground. Individual building zones can be served independently of one another, without requiring a separate, complete AHU for each room.

Decentralized units can be particularly advantageous when individual rooms need to be retrofitted or when the installation of an extensive ductwork system is structurally challenging.

Particularly in renovation projects, the building should therefore be assessed first, and a decision should then be made as to which supply concept can be implemented in a technically and economically viable way.

Why is heat recovery important in educational buildings?

High volumes of outdoor air improve indoor air quality, but during the heating season they also increase heating demand. Without heat recovery, a large portion of the heat carried away with the exhaust air would be lost unused. A suitable heat recovery system transfers part of this energy to the outdoor air, thereby reducing the additional heating demand. Depending on the system design, energy recovery can also offer energy-saving benefits during cooling operation.

The type of heat recovery that makes sense depends on the specific system. We explain the different systems in the section on heat recovery in AHUs.

What are the differences between daycare centers, schools, and colleges?

Although all these buildings serve educational or childcare purposes, their usage profiles differ. The air-handling concept should therefore not simply be transferred from one building type to another.

• Daycare centers: Group rooms are used for extended periods of time. In addition to indoor air quality and low noise levels, demand-based air distribution and an indoor climate that is comfortable for children and caregivers play an important role.
• Schools: Classrooms often have a high occupancy density with clearly structured class and recess times. A CO₂- or occupancy-based control system can be particularly useful here.
• Colleges and universities: Usage ranges from small seminar rooms to offices and laboratories to large lecture halls. As a result, very different airflow rates and air-handling concepts may be required within a single building.

Universities may also have rooms with special requirements. Laboratories or cleanrooms should not be treated like normal seminar or classroom spaces, but rather require an air-handling concept tailored to their specific use.

Which HANSA AHUs are suitable for educational and childcare facilities?

Depending on the required airflow and building design, various HANSA unit series can be used.

The Blue Line enables custom-designed central or zone-based air-handling solutions and is particularly suitable when airflow rate, unit dimensions, components, and controls need to be configured specifically for the project.

The Kompakt Line combines the essential functions of an AHU in a compact design and can be used, for example, for floor-level solutions or smaller educational and childcare facilities.

The Luftbox 800 also provides a decentralized solution for room-by-room ventilation. It may be particularly suitable for individual classrooms and corresponding retrofit projects.

Therefore, the appropriate solution cannot be determined solely based on the type of building. Airflow rates, room layout, acoustic requirements, installation options, ductwork, heating and cooling needs, as well as the desired control concept must all be considered together.

For more information and specific examples of units, see Ventilation for Schools and Educational Institutions.

Office and administrative buildings place a wide range of demands on the air-handling system. Private offices, open-plan offices, conference rooms, and shared areas differ—sometimes significantly—in terms of occupancy, usage, and thermal load.

A suitable air-handling concept must therefore combine good indoor air quality and thermal comfort with energy-efficient operation. It is particularly important to adjust the airflow rate and air treatment as closely as possible to the actual needs of the various areas.

What requirements do office buildings place on air-handling systems?

People, lighting, computers, and other technical equipment release heat into the room. At the same time, the occupants generate carbon dioxide (CO₂), moisture, and other usage-related pollutant loads.

The air-handling system therefore does more than simply exchange air. Depending on the building design, it can filter outdoor air, heat or cool the supply air, and thus help create suitable conditions for the use of the rooms.

Which functions are actually needed depends on the building. A small administrative building has different requirements than a multi-story office complex with open-plan offices, conference areas, and highly variable occupancy.

Why is demand-controlled ventilation particularly useful in offices?

Occupancy in modern office buildings is often not constant. Meeting rooms, for example, are used by many people at times and then remain empty for extended periods. Even in office areas, the actual number of people present can fluctuate significantly throughout the day.

A constant airflow rate would not account for these differences. With demand-based ventilation, however, the airflow can be adjusted according to actual usage.

Depending on the system design, factors such as CO₂ levels, room temperatures, occupancy data, or time schedules can be used for this purpose. Fans, dampers, and heating and cooling functions can be controlled accordingly. This allows for coordinated regulation.

This allows the energy consumption required for air movement and air treatment to be reduced, particularly during periods of low occupancy.

What role do temperature and thermal comfort play?

In addition to indoor air quality, room temperature is an essential component of a pleasant work environment. However, the thermal requirements within a building can vary significantly.

Solar radiation, facade orientation, occupancy, and internal heat loads from lighting and technical equipment influence the cooling and heating requirements. In particular, rooms with large glass surfaces or high occupancy may experience significant heat loads at times.

When designing an AHU, therefore, it is not enough to consider only the required outdoor air volumes. Heating and cooling requirements, as well as the interaction with other building services systems, must also be taken into account.

Why are heat recovery and low pressure drops important?

Office buildings are in use for many hours of the day. As a result, even relatively small differences in energy demand can have a significant impact over the operating period.

Efficient heat recovery can harness a large portion of the thermal energy contained in the exhaust air. At the same time, pressure drops in filters, heat exchangers, silencers, and other components affect the required fan capacity.

An energy-efficient AHU is therefore not created by a single component that is as efficient as possible. What is crucial is the interplay between heat recovery, fans, pressure drops, airflow rates, and control systems.

More information about energy efficiency and quality is available under HANSA Quality and Energy Efficiency.

How important is acoustics in the office?

Noise from the ventilation system can be perceived as disruptive, particularly in offices, meeting rooms, and areas designated for concentrated work. Acoustics should therefore be taken into account as early as the planning phase of the air-handling system.

It is not only the AHU itself that is relevant here. Fans, air velocities, the ductwork network, silencers, and air diffusers collectively influence sound transmission into the rooms.

A properly sized system can offer advantages here, as it helps avoid unnecessarily high air velocities and consistently high fan speeds.

Centralized or zone-based—which air-handling concept is best suited for office buildings?

Larger office and administrative buildings are often served by central AHUs or by multiple units for different building zones. Which option makes sense depends, among other things, on the building’s size, use, room layout, and available technical spaces.

Dividing the building into different supply zones can be particularly beneficial when usage times or requirements differ significantly. Office spaces, conference areas, or other usage zones can thus be operated according to demand.

The installation location of the AHU also influences the planning. Technical centers, rooftops, or other installation sites place different demands on the unit’s dimensions, airflow, maintenance access, and, if necessary, weather protection.

Why should the AHU be compatible with the building?

Especially in larger office buildings, available technical spaces and structural constraints can significantly influence the unit’s design. Specified dimensions, connection orientations, airflow rates, or access routes cannot always be accommodated by a standardized unit configuration.

Custom-designed AHUs make it possible to tailor dimensions, air connections, components, performance ranges, and control functions to the specific project. This is important for both new construction and the modernization of existing buildings.

Which HANSA AHUs are suitable for offices and administrative buildings?

Depending on the building size, airflow capacity, and system design, different AHUs may be suitable for office and administrative buildings.

The Blue Line enables project-specific design of AHUs. Unit dimensions, airflow rates, heat recovery, heating and cooling functions, as well as the control system, can be configured according to the requirements of the specific building.

For more compact system designs, the Kompakt Line offers another option. Which unit concept makes sense depends not only on the required air volume, but also on the installation location, space constraints, usage patterns, and the required functions.

For more information, see the HANSA application area: AHUs for Offices and Administrative Buildings.

The requirements for ventilation and air-handling systems in industrial and production buildings can vary considerably. While some areas primarily require suitable working conditions for employees, in others the necessary air conditions are largely determined by production processes, machinery, or products.

Heat, moisture, dust, airborne contaminants, or high airflow rates can place special demands on an air-handling unit (AHU). Project-specific design is therefore essential to ensure that airflow capacity, air treatment, materials, heat recovery, and controls are matched to the application.

What functions does an AHU perform in industrial applications?

The functions of an AHU depend on its intended application. In production halls, for example, removing excess heat may be the main priority. Other processes require defined temperatures, humidity conditions, or a continuous supply of conditioned outdoor air.

At the same time, the needs of people working in the building must be considered. Process requirements and indoor climate requirements may therefore need to be addressed within the same system.

The ventilation and air-handling concept should be developed around these actual requirements. Only then can the necessary airflow rates and AHU functions be determined.

Which process loads must be considered during design?

Production processes can generate substantial heat and contaminant loads. Machinery, furnaces, electrical equipment, and other technical installations, for example, release heat into their surroundings. Depending on the process, moisture, dust, odors, or other substances may also be generated.

The key design consideration is which of these loads the ventilation and air-handling system is intended to remove or control. Process extraction and other specialized systems may also be required and must be coordinated with the general ventilation system.

Sizing a system solely on the basis of the hall's floor area is therefore often insufficient. The building's use, production processes, and resulting loads must be considered from the planning stage onward.

Why might industrial applications require high airflow rates?

Large production areas and high internal loads can require correspondingly high airflow rates. This directly affects the sizing of the AHU, fans, filters, heat exchangers, and ductwork.

As airflow increases, the energy required to move the air also becomes more significant. Pressure drops within the AHU and the duct system should therefore be considered during design.

The objective is not to move as much air as possible, but to provide the airflow required for the particular process and application with an appropriate level of energy consumption.

What role do temperature and humidity play in production?

In production areas, temperature and humidity can affect more than employee comfort. In certain applications, they also influence production processes, materials, or the quality of manufactured products.

Depending on the application, the supply air may therefore need to be heated, cooled, humidified, or dehumidified. The required air treatment is determined by the specified room or process conditions.

Applications in which air conditions must be maintained within narrow limits are particularly demanding. In such cases, air treatment, sensors, and control systems must be considered as an integrated system.

How can energy be recovered from extract air?

At high airflow rates, substantial amounts of thermal energy can be discharged with the extract air. Heat recovery is therefore an important part of the energy concept for many industrial ventilation and air-handling systems.

However, the most suitable heat recovery system depends on the application. Alongside energy efficiency, factors such as pressure drops, air quality, and possible transfer between extract air and supply air must be considered.

Where complete separation of the airstreams is required, run-around coil systems, for example, may offer advantages. In other applications, plate heat exchangers or rotary heat exchangers may be more suitable.

We explain the different options in more detail in Heat Recovery in Air-Handling Units.

Why are robust and adaptable AHUs important in industry?

Industrial AHUs often need to be adapted to specific spatial and technical conditions. High airflow rates, limited plant space, existing building structures, or special connection orientations may require a customized unit design.

Materials and surfaces must also suit the operating environment. Depending on the ambient conditions, higher requirements may apply to corrosion protection, the casing, or the design of individual components.

Outdoor installation introduces additional weather-related factors, including rain, snow, frost, and solar radiation. We discuss these requirements in more detail in Outdoor Installation of Air-Handling Units.

When must ATEX requirements be considered for AHUs?

Certain industrial applications may involve flammable gases, vapors, mists, or dusts that can form an explosive atmosphere when mixed with air. In these areas, explosion protection requirements must be considered when planning the ventilation and air-handling system.

The requirements for the AHU depend on the specific hazards and the designated hazardous-area classification. Among other things, a distinction must be made between explosive atmospheres that may occur inside the unit, outside the unit, or in both areas.

ATEX requirements can affect various AHU components, including fans, motors, electrical components, sensors, and other equipment. Potential ignition sources and electrostatic charging must also be taken into account in the technical design.

An AHU intended for use in a potentially explosive atmosphere should therefore not be adapted retrospectively from an already finalized standard design. Explosion protection, hazardous-area classification, and the resulting technical requirements must be incorporated into the project-specific unit design from the outset.

Why are control systems particularly important in production facilities?

Production conditions are not necessarily constant. Machines are switched on and off, production lines change operating states, and heat or contaminant loads may vary throughout the day.

A suitable control system can adapt the AHU to these different operating conditions. Airflow rates, temperatures, and other functions can be controlled and regulated according to the measured variables relevant to the particular process.

As a result, the unit does not need to operate continuously at its maximum design conditions. This does, however, require the possible operating states and relevant control variables to be defined during the planning stage.

Which HANSA AHUs are suitable for industrial and production applications?

Industrial applications particularly benefit from the ability to tailor an AHU to the task at hand. The Blue Line and Free Line product ranges can be configured for each project in terms of airflow capacity, dimensions, components, heat recovery, heating and cooling provision, and controls. ATEX-compliant versions are also available.

The key question is therefore not simply which AHU is suitable for “industry.” The starting point is the specific process, the resulting loads, the required air conditions, and the structural constraints. These factors determine the unit configuration best suited to the production environment.

For more information, see the HANSA application area Air-Handling Units for Industry and Production.

Hospitals, rooms used for medical purposes, laboratories, and cleanrooms place special demands on air handling systems. Air quality, filtration, pressure conditions, temperature, and in some cases humidity must be controlled precisely.

However, the requirements vary significantly depending on the application. An operating room is not a laboratory, and a laboratory is not necessarily a cleanroom. Air-handling units (AHUs) for sensitive areas must therefore be tailored to the specific use and the applicable hygiene, technical, and, where relevant, safety requirements.

What distinguishes sensitive areas from other air handling applications?

Conventional comfort ventilation primarily focuses on indoor air quality and thermal comfort. In sensitive areas, additional requirements may apply that are directly related to how the room is used.

These may include defined air cleanliness levels, multistage filtration concepts, controlled pressure conditions, or special requirements for materials and the hygienic design of the AHU.

The consequences of a malfunction may also be more significant. Unit design, control, monitoring, and maintenance must therefore be considered together from the planning stage onward.

What requirements apply to hospitals and medical areas?

In hospitals, air handling requirements depend heavily on the use of each area. Patient rooms, examination rooms, operating areas, and other rooms used for medical purposes may have different requirements for airflow patterns, filtration, temperature, and pressure conditions.

Particularly in hygiene-sensitive areas, the AHU itself must not become a source of contamination. Its design, materials, and components should therefore allow hygienic cleaning, maintenance, and inspection.

Additional requirements apply to particularly sensitive medical applications. These must be defined for each project based on the intended room use and the relevant standards and regulations.

What special considerations apply to air handling systems in laboratories?

In laboratories, air handling requirements are largely determined by the work carried out there. Depending on the application, substances may be released or captured and extracted by fume cupboards and other equipment.

This can result in substantial fluctuations in supply and exhaust airflow rates. The air handling system must accommodate these operating conditions and maintain the required room pressure relationships.

It is also necessary to assess whether the exhaust air contains substances that impose special requirements on airflow routing, components, materials, or potential energy recovery. The transfer of undesirable substances from exhaust air to supply air must be prevented in accordance with the specific application requirements.

In laboratory buildings, coordination between the AHU, fume cupboards, exhaust air systems, controls, and safety concept is therefore particularly important.

What is essential in cleanrooms?

In cleanrooms, the primary objective is controlled air cleanliness. Depending on the application, defined limits for airborne particle concentrations must be maintained.

In addition to suitable filtration, airflow patterns, air change rates, room pressure, and the overall room design are important. The AHU is therefore a key component of a comprehensive cleanroom concept.

Many applications also require temperature and humidity to be maintained within specified ranges. These requirements may be determined by production processes, products, or sensitive materials.

Cleanroom technology must therefore not be reduced to selecting a particularly high filter class. What matters is a coordinated overall system comprising air treatment, filtration, airflow distribution, pressure control, controls, and room design.

What role do filters and pressure conditions play?

Filtration concepts must always suit the specific application. Depending on the requirements, several filter stages may be used within the air handling system. In particularly sensitive areas, additional terminal filters close to the supplied room may be necessary.

At the same time, defined pressure differences between rooms or building zones may be required. Positive pressure can, for example, help limit the ingress of contaminants into a sensitive area. Negative pressure, on the other hand, can be used to prevent contaminants from spreading from one room into adjacent areas.

The required pressure conditions depend on the intended use. Supply and exhaust airflow rates and the control system must be coordinated accordingly.

Further information is available in our article on Filters in Air-Handling Units .

Why is hygienic AHU design important?

Even a high-quality filtration concept cannot perform its intended function if unhygienic conditions develop inside the AHU. Unit design and accessibility must therefore be considered from the outset.

Smooth, suitable surfaces, accessible components, cleanable areas, appropriate seals, and controlled condensate drainage all contribute to hygienic operation.

Accessibility for subsequent inspection, cleaning, and maintenance is equally important. Hygiene is therefore not merely a characteristic of the unit's construction, but a responsibility throughout the entire life cycle of the air handling system.

For more information, see Hygiene Requirements for Air-Handling Units and VDI 6022 .

Why must control and monitoring be particularly reliable?

In sensitive areas, it is not enough simply to achieve the intended air conditions. Certain defined operating conditions may also need to be maintained continuously.

For this purpose, the control system can monitor and regulate, for example, airflow rates, temperatures, humidity levels, and pressure differences. Deviations from critical operating conditions should be detected and reported in accordance with the system concept.

Which parameters must be monitored and what response is required in the event of a deviation depend on the specific application and its safety and hygiene requirements.

Which HANSA AHUs are suitable for hygiene-sensitive areas?

HANSA can tailor AHUs to the project-specific requirements of hospitals, laboratories, cleanrooms, and other sensitive areas. With the Blue Line, unit design, filter stages, materials, air treatment, heat recovery, and controls can be configured to meet the requirements of each application.

Specially designed unit variants are available for applications with particular hygiene requirements. Hygienic design depends not only on individual components, but on the entire unit construction, including surfaces, seals, accessibility, filter arrangement, and condensate drainage.

The starting point for unit selection is therefore always the specific application. Only once the required air quality, pressure conditions, temperatures, humidity levels, and safety requirements have been defined can the appropriate AHU be configured.

Further information is available in the HANSA application areas Hygiene and Laboratories and Cleanrooms .

Museums, exhibition spaces, archives, and collection storage facilities place particular demands on air-handling systems. In addition to providing comfortable conditions for visitors and staff, the indoor climate often needs to protect sensitive exhibits and cultural heritage objects over the long term.

This involves more than maintaining specific temperature or humidity values. Stable climatic conditions and the avoidance of unnecessarily large or rapid fluctuations are especially important. The air-handling unit (AHU), its controls, and the building must therefore be considered as an integrated system.

Why is indoor climate control particularly challenging in museums?

Museums must meet different requirements simultaneously. Visitors need a comfortable indoor environment and sufficient outdoor air, while artworks and other exhibits may be sensitive to changes in their surroundings.

Changing outdoor conditions and internal loads from people, lighting, and technical equipment add to the challenge. The ventilation system must compensate for these influences without itself causing unnecessary fluctuations in the indoor climate.

The required climatic conditions depend on the cultural heritage objects on display or in storage. System design should therefore always be based on the actual requirements of the museum, exhibition area, archive, or storage facility.

How important are temperature and humidity?

Temperature and relative humidity affect many materials. Wood, paper, textiles, and other hygroscopic materials, for example, can absorb moisture from the surrounding air and release it again. Changes in indoor climatic conditions can therefore also cause changes within these materials.

For air-handling systems, this means that the desired setpoints are not the only consideration. It is equally important to determine how consistently these conditions can be maintained and how quickly the indoor climate changes.

Depending on the requirements, the AHU may therefore provide heating, cooling, humidification, and dehumidification. The functions actually needed must be determined for each project.

Why are stable conditions often more important than rigid setpoints?

For sensitive cultural heritage objects, large or rapid changes in ambient conditions can be more problematic than minor deviations from a specified setpoint. The control system should therefore avoid unnecessary switching between heating, cooling, humidification, and dehumidification.

The air-handling system should respond as smoothly as possible to changing conditions. This requires coordinated AHU design, sensors, and control strategies.

At the same time, the requirements of different collections can vary considerably. There is therefore no single museum climate suitable for every exhibit. The required conditions should be defined in consultation with the specialists responsible for the collection and its conservation.

What role do visitors and fluctuating occupancy play?

Visitor numbers in exhibition spaces can change significantly within a short period. People release heat, moisture, and carbon dioxide into the indoor air, thereby affecting conditions in the room.

A large number of visitors can therefore create substantially different ventilation and cooling demands than an almost empty exhibition space. The ventilation system must accommodate these changes without causing unnecessarily large fluctuations in climatic conditions.

Demand-controlled ventilation can help adjust outdoor airflow to actual occupancy. At the same time, the indoor conditions required to protect the exhibits must be maintained.

Why do exhibition spaces, archives, and collection storage facilities need different ventilation concepts?

Not every area of a museum building is used in the same way. Exhibition spaces receive visitors, whereas archives and collection storage facilities are often entered only occasionally.

Exhibition areas must therefore balance indoor air quality, visitor comfort, and the protection of exhibits. In archives and storage facilities, by contrast, the long-term stability of storage conditions may take priority.

Dividing the building into separate ventilation or control zones can therefore be beneficial. This allows airflow rates and air conditions to be adjusted to the respective use instead of controlling the entire building according to a single operating condition.

How important are filtration and outdoor air quality?

Outdoor air can introduce particles and other contaminants into the building. A filtration concept tailored to the application is therefore an important part of air-handling design for museums, archives, and storage facilities.

The required filtration depends, among other factors, on outdoor air quality, the building location, and the needs of the cultural heritage objects being protected. At the same time, filters create pressure drops that must be taken into account when designing an energy-efficient AHU.

We explain the fundamentals of filter selection and arrangement in more detail under Filters in Air-Handling Units.

How can climate stability and energy efficiency be combined?

Museums and archives may have long operating hours. At the same time, conditioning the air through heating, cooling, humidification, or dehumidification can require substantial amounts of energy.

Energy efficiency should therefore not be assessed on the basis of a single component. Heat recovery, pressure drops, fan power, airflow rates, thermal air treatment, and controls must be evaluated together.

A control strategy that provides only the air treatment actually required is particularly important. It should avoid unnecessary simultaneous or counteracting heating, cooling, humidification, and dehumidification.

You can find more information about these relationships in the HANSA overview of air-handling solutions and technology.

Which HANSA AHUs are suitable for museums and cultural heritage collections?

The requirements of museums, archives, and collection storage facilities can vary considerably from one project to another. Custom-designed AHUs therefore offer the flexibility to adapt airflow capacity, air treatment, and controls to the required climatic conditions.

With the Blue Line, heat recovery, filtration, heating and cooling functions, and, where required, humidification and dehumidification can be integrated into the AHU configuration. Dimensions, air connections, and control functions can also be tailored to the specific project.

The key is not simply to reach a particular setpoint. The entire air-handling system should be designed and controlled to maintain the conditions required for the respective cultural heritage objects as reliably and consistently as possible.

For more information, see the HANSA application area Air-Handling Units for Museums and Cultural Heritage.

Some applications place such specialized demands on ventilation and air-handling technology that we provide dedicated topic pages covering the relevant expertise. These include, in particular, indoor swimming pool climate control and cooling for IT facilities and data centers.

Air-Handling Units for Swimming Pools

Indoor swimming pools place particular demands on air-handling technology due to high humidity, evaporation, corrosive environmental conditions, and high energy demand. Controlled dehumidification, appropriate air distribution, and the most efficient possible use of available energy are essential.

With its Pool Line, HANSA develops air-handling units (AHUs) specifically for these requirements. Detailed technical information on swimming pool climate control, ventilation technology, VDI 2089, energy efficiency, and control systems is available in the Bäder-Klima Wiki .

Air-Handling Units for IT Facilities and Data Centers

Server rooms and data centers require reliable removal of high heat loads and place particular demands on cooling availability, energy efficiency, and control. Air-handling technology must be tailored to the IT infrastructure, the prevailing heat loads, and the specific cooling concept.

HANSA develops customized climate-control solutions for IT facilities and data centers. Further information on the specific requirements and technical solutions is available at IT-Cooling .
