General Information

Application

• Rectangular VAV terminal units for use in ventilation and air conditioning systems
• For controlling, restricting, or shutting off supply and extract air flows
• Closed-loop volume flow control using an external power supply
• For variable or constant volume flow systems
• Shut-off by means of switching (equipment supplied by others)
• Can also be used for duct or room pressure control with suitable control components

Special features

• Integral effective pressure sensor with 3 mm measuring holes (resistant to dust and pollution)
• Factory set-up or programming and aerodynamic function testing
• Parameters can also later be set on the control component. Depending on the control component, an additional adjustment device may be necessary

Nominal sizes

• 36 nominal sizes from 200 × 100 to 1000 × 600
• Not all attachments may be available or suitable for all sizes of terminal units

Variants

• TVT: VAV terminal unit
• TVT-D: VAV terminal unit with acoustic cladding
• Units with acoustic cladding and/or secondary silencer Type TX for demanding acoustic requirements
• Acoustic cladding cannot be retrofitted

Construction

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

Parts and characteristics

• Ready-to-commission unit which consists of mechanical parts and control components
• Averaging effective pressure sensor for volume flow rate measurement
• Damper blades
• Factory assembled control components complete with wiring and tubing
• Aerodynamic functional testing on a special test rig before shipping of each unit
• Set-up data is given on a label or volume flow rate scale affixed to the unit
• High volume flow rate control accuracy

Attachments
