Wester WRV 35L expansion tank for heating systems

For the manufacture of the expansion tank Wester WRV 18, high-quality steel is used. The equipment is designed for heating systems in which the heat carrier is water, which contains less than 50% glycol.
The installation of a membrane tank allows you to compensate for the thermal expansion of the coolant in closed-type heating systems. To separate the air and water chambers of the device, a membrane made of heat-resistant rubber is used. The flange, which is equipped with a tank, provides easy dismantling and replacement of the rubber membrane. The air cavity has a pre-pressure of 1.5 bar. The operating temperature range is -10ºС…+100ºС. Models up to 50 liters do not have supports.
