Type TVR

Combined with the fast TROX LABCONTROL control unit

TROX VAV controllers type TVR are circular flow rate controllers for variable supply or extract air systems. They can be used for almost any control, regulation and shut-off tasks in room air conditioning systems, and can be used for systems with normal acoustic requirements.

Product Description

Supply/exhaust air, pressure volume flow controller for round lines
Optionally available with flange
Housing of galvanised metall sheet; damper of plastic with seal
Housing optionally available with powder coating (TVR-P1)
Full airtight shut-off as per DIN EN 1751 Class 4 or 3
Designed for medium to low acoustic requirements
Optionally available with acoustic cladding to reduce case-radiated noise (TVRD)

TVR certificate according DIN EN 14175 Teil 6

The mechanical components and electronic components which are factory fitted, form the controls package. Each box is set up to the required flow rates and is subjected to an aerodynamic function test.

The boxes contain an averaging differential pressure sensor for air flow measurement and a control damper. The flow rate control is a closed circuit system with external power supply.

The control damper with plastic seal when closed complies with the air tightness requirements of DIN EN 1751. There are circular spigots on both sides. The controllers with additional acoustic cladding and/or a secondary circular silencer are suitable for very demanding acoustic requirements.

Characteristics

Integrated averaging differential pressure sensor with 3 mm measuring holes and so insensitive to dirt
Factory set up or programming of flow rate. This includes aerodynamic function test of each box using a dedicated test rig. Data covering set up is given on a test label attached to each controller
