Pump group used in heating and cooling systems. Mounted on the manifold with hydraulic coupling BLH 890 or between the heat/cooling source and the consumer. Prepares the medium at the correct temperature and pumps it to the system. ARV 362 ProClick rotary mixing valve (Kvs 6.3 m3/h). A mesh filter protects the pump and mixing valve from impurities. Shut-off valves with integrated thermometers to control the temperature of the medium at each connection. Non-return valve built into the tee on the return connection. Sleeves for mounting temperature sensors on each connection. Possibility of installation with the heat source on the right and left side. By mounting the ACT 443 ProClick or ARC 345 ProClick controller on the mixing valve, it is possible to automatically set the supply temperature of the system by fixed-temperature or weather-based and control the circulating pump.
