The compact volume flow controller VSRV optimises the energy economy in ventilation systems by adjusting the air supply and exhaust volume flow to the requirements of the zone to be ventilated.

The setting is performed via the maintenance free, motor driven damper with VAV-Compact controller (IP 54, CE i.a.w. 89336/EEC). The input signal for this is from an aerodynamically formed pressure sensor that determines the mean value. The volume flow controller can be mounted in the flow direction, independent of the location, in spiral duct systems.

• type VSRV can be insulated after installation
• Function range 0 – 600 Pa (overload capability ± 3000 Pa)
• Control function VAV-CAV- or open-loop-operation in external VAV-control-circuit
• Feedback signal damper position for fan optimiser-systems, current volume flow or differential pressure.
• Demand-dependent setting for variable volume flow with constant reference variable and DDC- or BUS-System. The operating range Vmin…Vmax can be controlled via switchable modes.
