Advantages:

Up to 90% energy recovery

The 3D cross-counterflow enthalpy exchanger transfers both heat and moisture from three directions – maximizing surface area and energy recovery efficiency during both the heating and cooling periods.

Enthalpy exchanger (ERV) – standard

The polymer enthalpy membrane conducts both heat and humidity in all units – standard equipment, no additional equipment required. Up to 87% enthalpy efficiency, no air drying in winter, condensate does not freeze below −30 °C, no condensate drainage required.

DC fans with constant airflow

All eight FAH models feature 10 variable speed DC fans with constant airflow compensation – automatically maintaining rated airflow regardless of duct static pressure or filter load. Up to 40% energy savings compared to AC motors.

A-energy class

Verified based on official EU energy labels (Regulation 1254/2014): All eight FRIGG FAH models – FAH-250 to FAH-2000 – belong to energy class A according to the current ecodesign assessment.

100% automatic BYPASS

In summer, the motorized bypass valve opens automatically when the outdoor temperature is within the adjustable comfort range – supplying the unit with fresh air without heat exchange, ensuring free-cooling ventilation.

RS485/Modbus and BMS integration

In addition to standard WiFi / Smart Life app control, FRIGG FAH devices also have RS485 / Modbus connectivity for building management system integration – suitable for lighter commercial building installations.
