Blue Line
Our Free Line units are freely adaptable and configurable air handling units for free cooling of all air flows from 2,500m3/h to over 100,000m3/h.
For the cooling of server rooms or the general dissipation of process heat, units from the Free Line series are perfectly adaptable to a range of applications and can perform the following functions:
The option of heat recovery with plate exchangers as recuperators is implemented in our Blue Line PT (PT=plate exchanger), Blue Line DPT (DPT=double plate exchanger) and Blue Line GS (GS=counterflow heat exchanger) series units.
As static systems, these recuperators pose no problems mechanically under defined design conditions. In addition, they usually provide adequate separation of the air streams.
Depending on requirements, we install plate heat exchangers with heightened corrosion protection or hydrophilic coatings for special applications.
Plate exchangers made of moisture-permeable materials are available as regenerators.
HANSA's Blue Line ASB+ exhaust-air side indirect evaporative cooling system has been a successful model since its introduction. Its investment and operating costs are very low when compared to mechanical cooling, and it allows cooling of the outside air of up to and over 12 Kelvin (see image below).
The HANSA-ASB+ system uses rigidly mounted nozzle assemblies that permit comprehensive and uniform humidification on the exhaust air side of the double plate exchanger used. Combined with increased corrosion protection of exposed components, this means that the system is durable and requires less maintenance.
Rotors are used as central energy recovery units in our Blue Line eco-R series.
This is an optimum application area for these components, as high air capacities are required and the exhaust air falls into categories ETA 1 to ETA 3 (see DIN EN 13779).
Your benefits when you choose our Blue Line eco-R system:
All our Blue Line units are individually configured and designed to suit the air conditioning task to be performed. Thanks to our modular HKG design, the series can be individually expanded through the addition of necessary components in each case, including integrated mechanical refrigeration or a heat pump (also reversible), a cold or hot water coil, and humidification, dehumidification and sterilisation units.
