Heat exchanger

Discover our state-of-the-art asymmetric high performance heat exchanger made of microbiologically non-metabolisable polypropylene, perfectly adapted to the requirements of your swimming pool dehumidifier. Our heat exchanger maximises efficiency by precisely accounting for airflow, heat recovery, flow losses and condensate drainage at various operating points.

Due to its integrated design, our high-performance heat exchanger is extremely effective throughout the entire depth of the unit. It ensures optimum efficiency over a wide range of outdoor temperatures. In addition, it is completely resistant to acids and alkalis and offers outstanding corrosion and ageing resistance.

Our polypropylene material meets the strict requirements of building material class B2 according to DIN 4102-1:1998 and has been tested by the Materials Testing Authority (MPA). The recuperation part of the heat exchanger has a special base plate that functions as an efficient condensate pan with integrated drain and water seal.

Integrated power-regulated heat pump

The integrated power-regulated heat pump enables energy-efficient dehumidification and heating of the swimming pool hall. The dimensioning and optimisation of the heat pump components takes into account factors such as air volume, dehumidification performance and electrical power consumption. By setting the optimum evaporation pressure, dehumidification of the air is ensured depending on the air conditions and the air volume.

An integrated subcooler increases the overall efficiency of the heat pump. An optional pool water condenser additionally allows the pool water to be heated.


Pure protection for clean air: Our filters complies with ISO 16800 and set new standards in filter technology. The filters are equipped with high-performance panel filter cells or pocket filters that ensure maximum filter performance. With a filtration efficiency that meets quality standards and a CE 1935/2004 food compatibility test certification, we offer you top quality.

Our filters are ready for any climate: with suitability for relative humidities of up to 100 %, they are the optimal choice for diverse environments. An intelligent filter mounting frame, sealed with self-sealing rubber lips, ensures a secure seal against the housing. Trust our filters - your air quality, our mission.

Control and regulation unit

Ultimate control: our switching and control equipment redefines efficiency. A pre-wired control cabinet contains all control, regulation and drive components, perfectly matched to your unit. From terminals for the main power supply to motor and control cables, main/repair switches and motor control components - everything is precisely integrated. Our electronic control system sets new standards in programming freedom. With an object-oriented Graphic Editor and the option for expansion via peripheral bus with local or remote I/O expansion modules, you retain full control. Thanks to potential-free contacts suitable for 230 V / 2 A, we offer a flexible control solution that adapts perfectly to your needs. The control cabinet is mounted on the unit and foldable for transport or possible for wall mounting with 15 metre cable length.

Factory test run

For highest quality: Each unit undergoes a documented test run before delivery. The control cabinet test is carried out in accordance with DIN EN 60204 and includes the assembly and wiring in the test field. Visual and leak checks of all installations guarantee your safety. In addition, a detailed test run and the setting of safety-relevant parameters are carried out. Our software and all control and regulation components are subject to a detailed function check. The pressure measurement report from the factory test run is included in the scope of delivery. We rely on the highest quality standards to meet your requirements.
