TROX has developed a new measurement method and a new type of damper blade for air handling units that even works for low air flows. The TVE unit is compact and saves energy.

Type TVE VAV terminal units apply a new measurement principle as the volume flow rate is measured not with a probe or sensor, but by means of the damper blade itself. This innovative design allows for a reduction in length and helps to ensure precise measurement results even in the case of unfavourable upstream conditions; with dynamic measurement, this is even independent of the airflow direction.

The new damper blade is part of the new VAV terminal units, Type TVE.

Advantages

  • Works perfectly even with unfavourable upstream conditions
  • The relation between damper blade position and differential pressure is stored as a characteristic relationship in the controller
  • Higher measurement accuracy even with low airflow velocities from 0.5m/s
  • Nominal sizes of 100, 125, 160, 200, 250mm
  • Volume flow rates of 14-2300m³/h (4-640 l/s)
  • Volume flow rate range of 1:25
  • Choice of static or dynamic transducer
  • Available with Easy controller, Compact controller or Modbus RTU variant for connection to the central BMS
  • Airflow direction is not critical if dynamic measurement is used
  • Release button on control component allows for easy replacement of the component
