TVE-Q

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 0.8 - 8 m/s
• Compact dimensions for use in confined ceiling areas

Nominal sizes

• 200 × 100, 300 × 100

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 Modbus: variant with Modbus RTU interface and disply; Plug-and-play solution in conjunction with X-AIRCONTROL room control
• Compact controller BACnet: Variant with BACnet-MS/TP interface and display; can also be converted to Modbus RTU by the customer

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 air duct profiles
• Position of the damper blade can be seen from the outside via position indicator
• Simple exchange of the control components possible
• Acoustic cladding cannot be retrofitted
