KVR-RD constant flow rate controller

The KVR-RD is a constant flow rate controller operated without external energy. The KVR-RD is designed to be completely incorporated into air ducts or fittings. The range of operation is (depending on size) between 15 m³/h and 700 m³/h at temperatures between -10 and 60°C. The installation is equally possible in horizontal or vertical ducts of supply and exhaust air systems. The control accuracy is +/- 10% from the configured nominal flow rate.
