Sound-insulated Flatbox for exhaust air with centrifugal fan and shutter with servomotor, channel size 900 mm x 300 mm

Product description

Model KFR-A, KFD-A exhaust air

  • Sound-insulated Flatbox for air extraction.
  • With fan and shutter with servomotor.
  • Control using operator unit contained in supply air unit - no separate operator unit needed.

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.
