A correctly chosen expansion tank prevents sudden changes of pressure to elongate the life of system elements and pump.
Membranes of tanks are spherical. The metal sheet does not touch the tank and thus all tanks can be used for both heating and cooling systems.
Membranes are made of EPDM, which is a quality membrane polymer used in applications to food produces. Without undesirable odours.
Operation temperature range of tanks are from -10ºC to 100ºC.
