For precise control of normal to high constant volume flow rates

Rectangular, mechanically self-powered air terminal units for supply and extract air systems with constant air volume flows


  • Suitable for volume flow rates up to 12600 m³/h or 3500 l/s
  • Volume flow rate adjustment from outside by rotary knob
  • Easy retrofitting of an actuator for volume flow setpoint adjustment
  • High control accuracy
  • No on-site test measurements required for commissioning
  • Casing air leakage to EN 1751, class C
  • Visual display of the damper blade position for operating point optimisation

 


Optional equipment and accessories


  • Acoustic cladding for the reduction of case-radiated noise
  • Secondary silencer Type TX for the reduction of air-regenerated noise
  • Hot water heat exchanger Type WT for reheating the airflow
  • Actuator for setpoint value switching or steady operation

General information

Application

  • Rectangular CAV terminal units for supply or extract air volume flow control in constant volume flow systems
  • Mechanical self-powered volume flow control without external power supply
  • Simplified project handling by ordering based on nominal size


Special features

  • Setting of the volume flow setpoint from the outside by rotary knob
  • High control accuracy of the set volume flow rate
  • Correct operation even under unfavourable upstream conditions
  • Visual display of the damper blade position for operating point optimisation
  • Easy retrofitting of an actuator for volume flow setpoint adjustment


Nominal sizes

  • 19 nominal sizes from 200 × 100 – 600 × 600 mm



Variants

  • EN: Air terminal units
  • EN-D: Air terminal units with acoustic cladding
