TVE

Application

• Circular VAV terminal units for use in ventilation and air 

  conditioning systems
• For almost all tasks when controlling, restricting, or shutting off supply and extract air flows
• Also for unfavourable upstream conditions at low air velocities
• Closed-loop volume flow control using an external power supply
• For variable or constant volume flow systems
• Shut-off by override control (by others)

Special characteristics

• High differential pressure signal with small angle of attack

• Factory set-up or programming and aerodynamic function testing
• Volume flow rate can be measured and subsequently adjusted, additional adjustment tool may be required (depending on the variant of the control component)
• Tubeless differential pressure measurement via damper blade
• Differential pressure transmission through differential pressure duct in shaft
• Any airflow direction if dynamic transducer is used
• Any installation orientation also with static transducer
• Suitable for airflow velocities of 0.5 – 13 m/s
• Compact dimensions for use in confined ceiling areas

Nominal sizes

• 100, 125, 160, 200, 250, 315, 400
