TROX Technik has launched the TVE-Q Series.
The ventilation component manufactuere specifically designed the air terminal unit for use with rectangular duct ventilation systems.
With the introduction of the TVE Series, 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, designed for use with rectangular duct ventilation systems.
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 differential pressure is measured directly via the damper blade
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 is that 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.
For easy revision, the compact controller can be removed and reconnected - tool-free
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 include the newly designed lip seal generates virtually no air-generated noise.
The modular design of the TVE control units have the option of a Modbus interface for Plug and 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.
The patented measuring principle is based on a hose-free differential pressure measurement directly via the damper blade
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.
