Diaphragm expansion vessel REFLEX G-1000x740, 1000L, 10 bar / 70°C, threaded connection G1 1/2", light grey, for heating and cooling systems, standing, with replaceable membrane 8546005

Expansion vessels are designed to equalize and stabilize pressure fluctuations caused by temperature changes and maintain pressure at an acceptable level. The operating principle of a closed pressure expansion vessel is based on a diaphragm that separates the water and gas spaces, thus preventing gas from penetrating the water. The water space is connected to the installation via a connection. Reflex G - is a diaphragm expansion vessel for closed heating and cooling water systems. The vessel design complies with PN-EN 13831 and VDI 4708 or AD 2000 standards. Approval according to the Pressure Equipment Directive 2014/68/EU. Characteristics:
