Single Duct Terminal Units Type ‘TVR/TVRD’

FOR THE MOST DIVERSE APPLICATIONS REGARDING STANDARD VOLUME FLOW RATE RANGES

Circular VAV terminal units for standard applications regarding the supply air or extract air control in variable air volume systems

  • Suitable for the control of volume flow rate, room pressure or duct pressure
  • Electronic control components for different applications (Easy, Compact, Universal, and LABCONTROL)
  • High control accuracy even with upstream bend (R = 1D)
  • Suitable for airflow velocities up to 13 m/s
  • Closed blade air leakage to EN 1751, up to class 4
  • Casing air leakage to EN 1751, class C

Optional equipment and accessories

  • Acoustic cladding for the reduction of case-radiated noise
  • Secondary silencer Type CA, CS or CF for the reduction of air-regenerated noise
  • Hot water heat exchanger Type WL and electric air heater Type EL for reheating the airflow
