TROX CAV BOX (RN)

FOR THE PRECISE CONTROL OF CONSTANT VOLUME FLOW RATES

Circular self-powered volume flow controllers for the control of supply air or extract air in constant air volume systems

  • Volume flow rate can be set using an external scale, no tools required
  • High control accuracy
  • No on-site test measurements required for commissioning
  • Suitable for airflow velocities of up to 12 m/s
  • Any installation orientation; maintenance-free
  • Casing air leakage to EN 1751, class C
  • Nominal size: 80-400 mm
  • Volume flow rate range: 11 – 1400 l/s or 40 – 5040 m³/h
  • Volume flow rate control range: Approx. 25 to 100 % of the nominal volume flow rate
  • Scale accuracy: ±4%
  • Minimum differential pressure: 50 Pa (nominal size 80: 100 Pa)
  • Maximum differential pressure: 1000 Pa 
  • Operating temperature: 10 to 50 °C 
  • RN-S: Compact-height volume flow controller
  • RN: Volume flow controller
  • RN-D: Volume flow controller with acoustic cladding
  • RN-FL: Volume flow controller with flanges on both ends
  • RN-D-FL: Volume flow controller with acoustic cladding and flanges on both ends
  • Units with acoustic cladding and/or a secondary silencer Type CA or CS for demanding acoustic requirements
  • Acoustic cladding cannot be retrofitted
