Cabinet

It is made of galvanized sheet metal, painted in RAL 9010 colour. Other colours on request. The exhaust section is thermally and noise insulated and finished with an anodised adjustable aluminium louvre. The water heater screens include an inlet filter. Frame in anodised aluminium (DOR-N CER).

Fans

Direct drive radial fans are used. Single-phase asynchronous motors with thermocontacts are provided to allow control by changing the voltage. IP22 protection, EC motors also available on request.

Regulation

is carried out with the DR-CP4 controller, to which only 1 aperture can be connected. The controller is designed for AC motors and allows the connection of a door contact and a room thermostat. Alternatively, the DR-CPhr touch panel controller is available, which is designed for AC and EC motors, allows manual control as well as control from higher-level systems (Modbus, BMS) and is equipped with additional functions (time clock, frost protection, door contact, curtain chaining, etc.).

Frost protection

Supplied screens are circulation screens with air intake from the room and are therefore not equipped with frost protection.
