Reduces dry air in winter through moisture recovery.

Application: Ventilation units.

Odors or harmful substances are not transmitted thanks to the special membrane.

Country approvals: Germany, Austria, Switzerland, France, Italy, Poland, Czech Republic.

Enthalpy heat exchangers for the 304/404 SOL and 504 ventilation compact units to replace the cross-flow heat exchanger during the winter months. Highly efficient, moisture-transferring counterflow heat exchanger with a selectively permeable plastic membrane. This membrane of the heat exchanger allows moisture from the exhaust air to be recovered and transferred to the supply air, thereby increasing the low relative humidity in rooms during the winter months. No transfer of gases and contaminants, long lifespan, high tightness, low pressure loss, antimicrobial, frost and heat resistant.
