General information

Ready for Passive House

KCX heat recovery fans are self-adjusting units for mechanical treatment of air (heat recovery, air filtration and heating) in stores, in homes, homes, and offices.

The unit is designed to remove contamination and provide fresh air. Heat recovery is based on the heat transfer between exhaust and supply air provided by the counter-current plateHeat exchanger.

KCX + units are available in both vertical and horizontal positions. Circulation connections on the unit of size ø 125 to ø 250 are designed to connect the heat recovery unit to the entire ventilation system. The unit is ready for interoperability with external air handling functions such as cooling water, heating water and ground exchanger.

The air handling unit body is made of powder coated steel sheet EPP (foam polypropylene). It has a 100% airtight bypass. Thanks to these solutions, KCX + meets all the stringent requirements of European certification systems.

Control system

The compact KCX + features an automatic monitoring and control system with an intuitive touch panel control. This allows you to pre-screen all required operating parameters (temperature, filter quality, fan speeds, heat recovery rate) and adjust fan operation with other components such as electric or water heater, water cooler or DX cooler.

The control units of the recuperation unit also control the operation of other external components installed in the building. The Ethernet module (optional) provides full control of the recuperator from mobile devices.
