Rectangular CAV Terminal Units
Volume flow controllers type VRRK are used for maintaining a constant volume on extract and supply air systems covering a wide range of sizes and volumes to suit any application. Their task is to keep a default nominal value of the volume flow constantly, lastingly and independently of the varying pressure in the duct.
Constant volume flow controllers work with a smooth-running, asymmetrically angled plate, which guarantees a sensitive responding behaviour even in case of low volume flows.
Adjustable in the field over a set volume range, the Constant Volume Terminal type VRRK ensures a constant supply of air of up to 10,000m3/hr to a room.
Key Features:
- Factory Parameterisation to client requirements
- Maintenance free
- High precision control
- Field Adjustable
Sizes:
- A full range of sizes from 200*100mm up to 600mm2
Ranges:
- 330 up to 10,000m3/hr
Materials:
- Galvanised Steel
