FU 28

It is possbile to purchase a FU 28 heat pipe unit with filter, which is connected to the VPL 28 unit.

The heat pipe slightly raises the temperature of the outdoor air, thereby increasing the heat pump’s efficiency in the VPL 28 aggregate significantly during the winter.

With an integrated FU 28 heat pipe unit, in most cases there is no need for a heating coil with mixing circuit.

For FU 28 a bag filter ISO ePM10 >50% (M5) and ISO ePM1 65-80% (F7) can be ordered.
