KFR-K, KFD-K supply air model with cooling function
- Sound-insulated Flatbox for ventilation.
- With fan, shutter with servomotor, air filter, water-air heater and cooling register.
- With control unit for supply and exhaust air unit.
- Connections for water-air heater and cooling register, can either be positioned in one or the other longitudinal side.
Features
- Compact unit for supply or exhaust air.
- Housing has 30 mm of rock wool thermal and sound insulation.
- Internal pressure losses are very low thanks to large flow-through areas. The housings are very smooth on the inside and outside and air-tight. This results in very quiet operations, few internal air noises and makes them easy to clean.
- No elaborate wiring or installation of attachments needed since all components are fitted ready for use.
- Control unit included in the scope of delivery of supply air unit.
- Configuration information for water/air heaters can be accessed online.
- IP 43 degree of protection.
Control unit
- One control unit can be used to jointly control a supply air and exhaust air flat box.
- Supply air flat box KFR / KFD and KFR-K / KFD-K: Control unit included in scope of delivery.
- Exhaust air flat box KFR-A / KFD-A: No control unit included, controlled using control unit of supply air flat box or transformer.
- If there is no KFR-A / KFD-A connected to the control unit, a 230 V transformer-type controllable fan can also be controlled instead (e.g. EKR, ESQ). Note: The power consumption of the exhaust air unit must not exceed that of the supply air unit.
- The control unit takes on the following functions:
- Selection of operating mode (supply air/circulating air).
- 3 levels of fan control
- Indication of current operating mode and setpoint temperature.
- Specification of setpoint temperature on control unit.
- Activation of servomotor, e.g. of heating circuit or cooling circuit.
- Release signal on refrigeration machine.
- Activation of a heating circulation pump.
- Fault indicator with LED and error code on control unit.
- Minimum and maximum limitation of supply air temperature.
- Frost protection monitoring of water-air heater.
- Air filter monitoring using differential pressure measurement.
- Room temperature sensor integrated on control unit.
- Activation of servomotor for shutter.
Mounting instructions
- Due to the efficient sound and thermal insulation, the unit can be fitted directly in suspended ceilings.
- Mounting bracket included in scope of delivery.
- Fit horizontally only.
