TVT SERIES
Rectangular VAV regulators for regulating air flows in variable air flow systems are suitable for supply and exhaust ventilation in rooms with increased requirements for the tightness of air duct networks
Air flow ranges up to 21,000 m³/h or 5,800 l/s
For regulating air flow and pressure both in the room and in the air duct.
Electronic controllers (Easy, Compact, Universal and LABCONTROL) for various applications
High control accuracy
Allowable air speed up to 10 m/s
Damper tightness according to EN 1751, class 3
Housing tightness according to EN 1751 class C
Optional equipment
Soundproofing coating to reduce noise generated by the chassis
Additional silencer TX Series to reduce noise generated by air flow
Water heating heat exchanger WT Series for secondary air heating
Description
VAV air flow controllers are equipped with an effective pressure sensor to measure air flow.
The control component (accessories) includes an effective pressure transducer that converts the effective pressure into an electrical signal, a controller and an actuator; Control functions can be implemented using Easy or Compact controllers, as well as using individual components (Universal or LABCONTROL).
For most applications, the setpoint comes from the room temperature controller.
The controller compares the actual value with the setpoint and modifies the drive control signal if there is a difference between the two values.
