The new VR1-N volumetric flow controller with a pressure range of 30 Pa - 600 Pa has been specially optimised for *low pressures and small volumetric flows in response to the requirements of our customers and the energy regulations on the market.
The VR1-N is suitable for the control of supply air and extract air in circular air ducts of ventilation and air-conditioning systems. It works without external energy and automatically keeps the set volume flow constant at variable pressures, with an excellent control accuracy of ± 10 % of the set volume flow.
The adjustment of the volumetric flow is infinitely variable and can be carried out very easily with one hand.
With its wide flow rate range of 30 m3/h - 2300 m3/h, a large selection of nominal sizes from CN80 - DN315 and a very large temperature window from -20 °C to +70 °C (even up to 90 °C for short periods), the VR1-N flow rate controller can be used in a variety of applications.
