- Polymerized cellulose enthalpy heat exchanger – recovers sensible energy and latent energy from the extracted air.
These heat exchangers are ideal for use in colder climates as they feature frost protection and they produce no condensation. There is an integrated electronic frost protection which prevents freezing in cold seasons. In case of the heat exchangers freezing the temperature sensor the supply fan is stopped to let warm air into the heat exchanger, once the supply fan is turned on the unit reverts to normal operation.
