ARP - Model CR-L30 Series -Radial Vane Damper Valve

• Diameter range DN150 ÷ DN2000
• Max temperature 200 °C
• Inlet fan modulating service
• Designed for 50 mm insulation
• CE marking

The use of a radial vane damper enhances the performance of the fan by:

• introducing swirl into the inlet of the fan in the direction of rotation;
• changing the fan curve as the damper moves;
• eliminating low-volume stalling of the fan.
