TVE

A NEW CONCEPT OF VOLUME FLOW MEASUREMENT

With the new volume flow controller of Type TVE, upstream conditions, installation dependent on airflow direction and strictly limited volume flow rate control ranges are a thing of the past. 

Thanks to the patented measurement principle, measured values are now determined directly on the damper blade – without measuring probes or other sensors – accurately and reliably! The large volume flow rate control range for airflow velocities from 0.5 m/s to 13 m/s offers a high degree of flexibility. Furthermore, with its compact construction, the TVE can be easily installed even inconfined spaces. 

  • Suitable for airflow velocity 0,5 - 13 m/s
  • Dimensions from Ø100 – Ø400
  • Can be installed directly to bend and branches
  • Tubeless pressure measures via damper blade
  • Any direction of flow with dynamic transducer

Application

TVE is a circular volume flow controller which works independently of the duct pressure, and which regulates to the desired air flow according to given setpoint. The setpoint for the desired air volume can, for example, be given as a 0 / 2-10 V signal or digitally via Modbus. TVE is intended for use in comfort ventilation, and can be delivered with dynamic sensor or static sensor. Static  sensors are typically used in situations where there is a high concentration of pollutants or aggressive substances in the air.

Design

TVE is a complete measuring and control unit where the air flow rates in ventilation systems can be set as required. The air volume is measured by pressure drop over the damper blade, and the measurement are transferred to the TROX VAV-controller throught the damper shaft. So there is no tubes or cables on the product. 


  • The VAV controller can be easily disassembled and mounted with a one-handed handle without use of tools. 
  • TVE complies with tightness class 3 (Ø100-Ø160) and 4 (Ø200-Ø400) with the damper blade in closed position, and class C the casing, in accordance with EN 1751.
  • Hygiene properties are in accordance with the requirements of VDI 6022. The technical properties of the TROX VAV controllers used on TVE can be found in separate data sheets. 
  • The controllers are delivered for analog control or with Modbus RTU communication. Both variants are available with dynamic or static pressure sensor. 
  • TVE can be delivered with acoustic cladding for reduced case-radiated noise

Installation

  • TVE can be mounted directly to bends and branches without affecting the measurement accuracy.
  • In order to limit noise and provide the best possible regulation, the damper blade / damper shaft should follow (be parallel to) the change of air direction in bends or branches. See Figure 3 and Figure 4 in the product data sheet.
  • Sufficient service distance must be set aside for commissioning and maintenance. It is recommended to install TVE with a minimum service distance in accordance with figure 5 and table 5 in the product data sheet.
  • If necessary, an inspection hatch must be installed.

TVE VAV terminal unit

TVE measures the air velocity via a measuring device in the damper blade. The pressure is transmitted to the damper motor through channels in the damper shaft. When there is a change in the duct pressure, for example by other volume controllers on the branch opening or closing, TVE will compensate by adjusting the damper blade until the desired airvolume is reached again.
