TROX TVE-Q-Easy Rectangular Variable Air Volume Terminal for Low Airflow Velocities, in Unfavorable Upstream Conditions, with Easy Controller

Application

• Square VAV terminal units for use in ventilation and air conditioning systems (AHUs)
• 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 the client)

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 axis
• Any airflow direction if dynamic transducer is used
• Any installation orientation also with static transducer
• Suitable for air velocities from 158 – 1575 ft/min
• Compact dimensions for use in confined ceiling areas

Nominal sizes

• 8″ x 4″, 12″ x 4″
• 8″ x 8″, 12″ x 8″, 16″ x 8″, 20″ x 8″, 24″ x 8″

Variants

• TVE-Q: VAV terminal unit
• TVE-Q with TX secondary silencer to reduce air-regenerated noise

Construction

• Galvanised sheet steel
• P1: Powder-coated, silver grey (RAL 7001)

Parts and characteristics

• Ready-to-commission unit which consists of mechanical parts and control components.
• Damper blade with integrated measuring unit
• Axis with differential pressure duct for measured value transmission
• Control component factory mounted
• Each unit is tested on a special aerodynamic test rig at the factory
• Documentation of the test rig data with a test label or a volume flow scale on the unit
• High control accuracy even in case of unfavourable upstream conditions

Attachments

• EASY controller: compact unit consisting of controller with potentiometers, differential pressure transducer and actuator
• Compact controller: compact unit consisting of controller, differential pressure transducer and actuator
• Compact controller: with Modbus RTU interface and display; plug-and-play solution in conjunction with X-AIRCONTROL room control system

Useful additions

• Secondary silencer Type TX for the reduction of airregenerated noise
• Hot water heat exchanger Type WT for reheating the airflow

Construction features

• Rectangular casing
• Flanges on both ends, suitable for duct connections
• Position of the damper blade indicated externally at position indicator
• Simple exchange of the control components possible
