Konforal Alarko expansion tanks are designed to compensate the changing volume of the heated water in heating systems, to maintain the static pressure created by the pump at the utilisation level in water production, and to compensate the changes in water flow rate. A right choice of expansion tank prevents sudden changes in pressure and provides a longer life for the pump and other elements of the system. Thanks to their hygienic EPDM membranes, Konforal Alarko expansion tanks are reliable in both heating and drinking water systems.
