SCHAKO VHPR Volumetric Flow Controller

SCHAKO VHPR Volumetric Flow Controller is an advanced controller system designed for regulation of variable and constant volumetric flows in ventilation and air-conditioning systems. Controls implemented flow rate either in constant or in variable way. Volumetric flow controller controls implemented flow rate either in constant or in variable way. Positive control to Vmin, Vmax or "Closed" is possible. This multi-functional control approach provides flexibility for different system requirements. Flow-optimized measuring cross with its measuring points distributed in accordance with median line method enables very accurate measurement of implemented volumetric flow. This advanced measuring system can be used already from air speeds as low as 0.8 m/s. Works within 21-13340 m³/h very wide volumetric flow range. This comprehensive capacity spectrum provides usage opportunity in HVAC applications of different sizes from small office areas to very large industrial facilities. Straight flow sections after bends are not required. This feature provides installation flexibility and offers advantage in applications with limited space. Compact design enables usage in various system configurations. Error of measurement is ±5% of rated volume. This high precision provides reliable and exact control in professional HVAC applications. Offers precision above industry standards. Flow-optimized measuring cross with measuring points distributed according to median line method provides very precise measurement opportunity. This system delivers reliable results even in irregular flow conditions. Capability to be used from air speeds as low as 0.8 m/s offers ideal solution in low-energy systems and applications requiring precise control. Wide operating range adapts to different system conditions. Precise adjustment to Vmin (minimum volumetric flow), Vmax (maximum volumetric flow) or completely "Closed" positions is possible with positive control system. This control flexibility adapts to variable operating conditions. Can be safely used in office buildings, hospitals, schools, shopping centers, large industrial facilities and all HVAC applications requiring precise volumetric flow control.
