The TVE volume flow controller for round ducts, which has been in use successfully for several years, has now been extended by its rectangular sister model, the TVE-Q. Both devices offer the same advantages and serve a wide range of applications with their different designs.
The volume flow controllers of the TVE series from TROX create a new dimension in volume control technology. Thanks to their unique and innovative measuring technology, up- and downstream lengths are a thing of the past while the installtion position is arbitrary. On top of that, it offers unimaginably accurate volume flow control ranges with a factor of up to 1:25.
Looking for all the benefits at a glance? In the following short video you'll learn everything you need to know about the new TVE-Q.
✓ Space-saving installation, as no up- or downstream lengths are required
✓ Wide flow rate control range for air velocities from 0.5 to 13 m/s
✓ Reliable measurement over the entire differential pressure range due to mapping measurement with variable C-value
✓ Large selection of controller variants and interfaces, as well as connection to X-AIRCONTROL
✓ Considerable cost savings due to terminal strip on the controller for electrical connection
✓ Prevention of installation errors due to flow direction on both sides (with dynamic transmitter)
✓ Easy maintenance as there are no interfering measuring components in and on the duct
✓ Easy mounting and dismounting of the actuator including integrated sensors
✓ Available nominal widths: up to 700 mm width, further sizes under development
The differential pressure is measured directly via the control damper, which is connected to the measuring unit on both sides by a patented system.
By eliminating the need for measuring probes and external connecting hoses, not only the size of the device but also the maintenance effort could be reduced.
In conjunction with the X-AIRCONTROL room control system, a direct integration into the central control system is possible - simply plug it in and you're done.
The damper blade functions both as an actuator and as a differential pressure sensor. Depending on the version, the pressure is detected statically or dynamically by the transmitter through the differential pressure channel in the axis and converted into an electrical signal.
This is constantly compared with the setpoint. In the event of a deviation, the integrated actuator adjusts the position of the damper blade. By this means, the volume flow is precisely measured and kept constant over the entire differential pressure range.

The unique patented measuring principle is based on hose-free differential pressure measurement directly via the control damper. This allows accurate measurement values to be reliably determined even at low air velocities of less than 1 m/s.
In both devices, both a dynamic and a static measuring principle can be used - for example, in the case of particularly polluted air. The symmetrical measuring probes are integrated directly into the damper blade on both sides. This makes the TVE and TVE-Q the only controllers that can be installed in either air direction when using a dynamic transmitter.
Another highlight: the sandwich-mounted sealing lip is as quiet as a whisper. Thanks to its uniquely designed tear-off edge, there is virtually no flow noise at the damper blade.
By eliminating the need for measuring probes or additional sensors, an extremely compact design is realized that allows easy and trouble-free installation even in tight spaces - in the case of dynamic measurement, even independent of the flow direction.
Even with static measurement, the installation position is arbitrary. Since no upstream or downstream lengths are required either, it is possible to mount the controller directly on a branch or on curves, for example.
The new TVE-Q also extends the range of possible applications to rectangular ducts. The sizes available range from 200-700 mm duct width.
The controllers of the TVE series have been designed on a modular basis using the concept of the tried-and-tested Easy design. The Compact variant, for instance, features the option of a Modbus interface, enabling a smart plug&play connection to the X-AIRCONTROL room control system.
Both the TVE and the TVE-Q are available with either a static or dynamic transmitter. An optional LCD display on the compact controller allows precise presetting directly on the device. The integrated terminal strips allow daisy chain connection without the need for extra junction boxes.
The one-piece housing design ensures reduced leakage and high efficiency. It also makes cleaning easier.
The TVE series is hygienically conformant to VDI 6022. For easy revision, the compact controller is removable and can be plugged back in again without any misalignment - all without tools.
Each volume flow controller features an individual QR code on the type plate upon delivery, that provides you with additional information at no extra effort, besides the information of the commission and order key.
