HANSA is modernizing 15 swimming pool ventilation units at Berliner Bäder-Betriebe

The ongoing retrofit project at five locations combines the replacement of control systems with the planned retrofitting of etaSmart^®. This project is the largest etaSmart^® and retrofit project to date for HANSA’s service division, etaTECH.

HANSA Klimasysteme is currently modernizing the control systems of 15 HANSA swimming pool ventilation units at five locations operated by Berliner Bäder-Betriebe (BBB). For twelve units, the project also includes the retrofitting of the AI-based control system etaSmart^®, including the etaSmart® Dashboard. The goal of this ongoing initiative is to simplify the operation of the systems and unlock opportunities for energy-efficient operational optimization.

New Control Technology for Long-Serving Systems

Some of the units have been in service for nearly 20 years. The retrofit focuses on replacing the existing control systems: As part of the project, the previous Siemens control technology is being replaced with Saia control technology. This is intended to achieve greater user-friendliness and more intuitive operation for the maintenance staff.

The project focuses on the targeted modernization of existing plant technology. By replacing the control systems, the existing ventilation units will be technically upgraded for their continued operation.

Retrofitting Twelve Units with etaSmart^®

Twelve of the 15 units are also scheduled to be equipped with etaSmart®. The system, developed by HANSA, uses model-based, predictive control to optimize the system’s energy efficiency. Models of the unit and the environment it serves are used to determine suitable operating conditions under the respective circumstances.

The project scope also includes the etaSmart^® Dashboard. It is designed to display energy savings and thus support subsequent evaluation during operation. Specific savings figures for the current project are not yet available.

Largest Project of Its Kind for etaTECH

The project at Berliner Bäder-Betriebe is the largest etaSmart^® and retrofit project in etaTECH’s history to date. Approximately 188 person-days are planned for implementation.

The ongoing project illustrates an approach to modernizing existing swimming pool ventilation systems: Equipment that has been in use for many years is being equipped with new control technology and enhanced with features for intelligent operational optimization.

C5-H Corrosion Protection Through Optimized Pretreatment

In a technical article published in the trade journal “Besser Lackieren,” our suppliers AD Chemicals and Cenaris Coating describe how optimized pretreatment of sheet metal in our powder coating line has improved the coating process and enabled us to achieve the high corrosion protection class C5-H.

The new process consists of a neutral cleaner, two rinsing steps, and “PreCoat ADL 4P” from AD Chemicals. The system’s performance was evaluated, among other things, based on salt spray tests in accordance with DIN EN ISO 9227 NSS:2024-10. The tests were conducted on Sendzimir galvanized DX51D +Z275 steel sheets with chemical pretreatment from AD Chemicals, at least 80 μm of Cenaris primer from the “Megaprimer” series, and at least 80 μm of topcoat from the “Megapol” series.

A key difference between the previous and current processes lies in the process temperature. Whereas it used to be around 55 °C, the new process can be carried out at approximately 30 °C.

The process is now more controllable and robust overall.

6.5 metric tons for clean air: HANSA ventilation unit for the Ludgerus School in Wettringen

A spectacular delivery for the new Ludgerus School building in Wettringen: A 6.5-metric-ton central ventilation unit from HANSA was hoisted onto the roof of the new school building using a mobile crane. In the future, the system will provide demand-based ventilation for the new classrooms and specialized rooms.

As part of the expansion of the Wettringen school complex, a two-story addition is being built at Ludgerus Elementary School to create additional space for school operations. According to the press release, the new building is scheduled to be ready for occupancy by the end of 2026. The central ventilation unit is a key component of the building’s technical systems. It is designed to provide demand-based supply and exhaust air in the new rooms, thereby ensuring a comfortable indoor climate.

The HANSA unit has truly impressive dimensions: it weighs 6.5 metric tons, is 11.50 meters long, and 3.50 meters wide. It arrived at the construction site via special transport during the night of August 7, 2026. On Friday morning, it was then hoisted onto the prepared steel roof structure using a 160-metric-ton mobile crane with its boom extended to 28 meters. After about a quarter of an hour, the ventilation unit was in its designated position.

The report by MV/EV online thus not only highlights a special moment on the construction site but also underscores the importance of modern ventilation technology in the expansion of contemporary school buildings.

Hansa Klimasysteme GmbH supports the “NurEinenAugenBlick” prevention campaign as a sponsoring company

Hansa Klimasysteme (a manufacturer of HVAC equipment and a pioneer in AI-based humidity control for swimming pools with “etaSmart”) is a sponsor of the nationwide prevention campaign “NurEinenAugenBlick – Your Glance Saves My Life.” The initiative’s goal is to encourage parents and guardians to be more vigilant—as a supplement to professional lifeguard supervision.

Aloha Aqualand Construction Project in Osterode

The article “Planning in an Existing Structure: Stratified Ventilation for a Swimming Pool Already Under Construction” addresses the challenge of implementing an efficient ventilation solution in a swimming pool that is already under construction. HANSA Klimasysteme supplied the central HVAC units and, in consultation with the Institute for Industrial Aerodynamics in Aachen, adapted the unit controls to the stratified flow concept. An industrial PC was installed to continuously record sensor data and store it in a measurement database. Based on this data, the concept can then be further optimized.
