TVE-Q - NOW WITH CORNERS AND EDGES

THE NEW TVE-Q CONTROL UNIT FROM TROX CONVINCES WITH SMART TECHNOLOGY

With the introduction of the TVE type, TROX presented for the first time a completely new measuring principle for precise detection of the differential pressure and automatic control of the volume flow rate. Now the round TVE is followed by the matching sister model TVE-Q for rectangular ducts.

In typical air terminal units, the differential pressure is measured by means of measuring probes in the ventilation duct. Here, both the correct inflow direction and a sufficient upstream length must be observed for accurate measurement results.

The innovation from TROX: The differential pressure is measured directly via the damper blade. The patented measuring principle has now been transferred to the rectangular TVE-Q variant. A central duct in the damper blade shaft transmits the differential pressure to the transducer, which is directly integrated into the controller casing. This enables accurate readings even at low air flow velocities < 1 m/s.

The advantage: by eliminating measuring probes, external hoses or sensors, an extremely compact design is achieved, which allows easy installation even in tight spaces - in the case of dynamic measurement even independent of the inflow direction. Even with static measurement, the installation position is arbitrary. Since no upstream or downstream lengths are necessary, the terminal unit can be mounted directly on a branch or on curves, for example.

Further highlights: The newly designed lip seal generates virtually no air-generated noise. The modularly designed control units type TVE have the option of a Modbus interface for Plug&Play connection to the X-AIRCONTROL room control system. And the integrated terminal strips allow connection without extra junction boxes.

In addition, the one-piece housing design ensures reduced leakage, high efficiency and easy cleaning of the TVE-Q, which conforms to VDI 6022 hygiene standards. For easy revision, the compact controller can be removed and reconnected - tool-free.

Each volume flow controller is parameterised to the customer's individual operating values and subjected to an individual ventilation test before shipment.

The TROX TVE-Q air terminal unit is available in nominal widths of 200 to 700 mm.

The patented measuring principle is based on a hose-free differential pressure measurement directly via the damper blade.
