Air flow regulator TVR

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 Circular VAV terminal units for variable and constant air volume systems, suitable for supply or extract air, available in seven nominal sizes. High control accuracy (even with upstream bend R = 1D). Ready-to-commission unit which consists of the mechanical parts and the electronic control components. Each unit contains an averaging differential pressure sensor for volume flow rate measurement and one damper blade. Factory assembled control components complete, with wiring and tubing differential pressure sensor with 3 mm measuring holes, thereby resistant to dust and pollution. Position of the damper blade indicated externally at shaft extension. Damper blade open at delivery, thereby air flow also given without control function; except variants with defined safety position NC.
