Expansion vessels for heating (expansion automats) are part of the equipment of water systems providing central heating. The expansion vessel maintains the pressure in the heating system and compensates for any changes in volume. It saves radiators, boiler and other elements of the heating system. In addition to classic expansion machines, you will also find a flow expansion machine on the market, which is designed for distribution. With us, you can choose from expansion automats with a pressure of 3 bar and a volume of between 24 and 5000 liters.
