The Freshbox 100 WiFi units are equipped with a counter-flow heat recovery core with a polystyrene core.
The Freshbox 100 ERV WiFi units are equipped with a counter-flow energy recovery core with an enthalpy membrane at the core.
- In the cold season the exhaust air heat and moisture are transferred to the supply air stream through the enthalpy membrane reducing the heat losses through ventilation.
- Consequently, it is the intake air heat and moisture transferred to the extract air stream through the enthalpy membrane in the warm season. This allows for a considerable reduction of the supply air temperature and humidity which, in turn, reduces the air conditioning load.

- Freshbox 100 (ERV) WiFi features an exhaust air temperature sensor downstream of the heat exchanger which disables the supply fan to let the warm extract air warm up the heat exchanger. After that the supply fan is turned on and the unit reverts to the normal operation mode.
