The new ÖkoSchwimm is a hybrid heat recovery ventilation system that incorporates three different, highly effective technologies working together to create an optimal environmental control solution for high specification pools. 

Three technologies combined for effective environmental control

The technologies focus on three main areas: The fans used in the units, optimising heat recovery ('free' heat) and energy efficient dehumidification. Firstly, the use of Ziehl-Abegg on-demand fan technology with backward curved fans, which utilise "auto-fan" technology, whereby the speed and power of the air-recirculation fan is managed automatically to enable significant energy savings whenever there is low demand. Secondly, Heatstar use cross-flow Hoval recuperators to optimise heat recovery. The recuperator passively conducts heat from the exhausted pool room air via a series of adjoining plates directly to the incoming colder fresh air. This process, in combination with the dehumidification heat pump, produces remarkable levels of heat recovery.

Last but by no means least, Heatstar utilise energy efficient dehumidification, powered by Copeland Scroll compressors. The unit's dehumidification heat pump creates a cold evaporator coil to condense the moisture present in the air to reduce humidity levels. Through this process the heat pump absorbs both latent and sensible energy which is upgraded and recycled back into both the pool room air and pool water. Efficiencies of over 380% are possible through this process.Pool heating is achieved from the packaged single unit using high quality Behncke heat exchangers.
