Precise Humidity Control to VDI 2089/1

Indoor swimming pool environments require strict humidity management. In accordance with the VDI 2089/1 standard, relative humidity in pool halls must be kept between 40% and 64% to prevent condensation damage, corrosion of structural elements, and microbial growth that can affect water and air quality.

Integrated Heat Recovery for Reduced Operating Costs

POOL units incorporate a plate heat recovery exchanger that recaptures thermal energy from the exhaust air stream, returning it to the supply air or pool water — significantly reducing the energy required for both dehumidification and space heating. The unit continuously monitors outdoor air temperature, indoor temperature, and absolute humidity, dynamically adjusting its operating mode to remove only the moisture necessary, avoiding over-dehumidification and unnecessary energy use.

Microprocessor-Controlled Automation

Each POOL unit comes equipped with a fully automatic microprocessor control system that manages all operating functions without manual input. The controller continuously evaluates sensor data and switches between operating modes — dehumidification, free cooling, mechanical cooling, and heat recovery — to maintain target conditions reliably across all seasons.
