Expansion vessels
The correct pressure is a basic requirement for the perfect functioning of heating, solar and cooling systems as well as pressure booster systems. Diaphragm expansion vessels offer a simple as well as intelligent solution here. They operate without electrical current, compressor or pump. Operation is very simple: a diaphragm separates the vessel into a water and gas chamber and prevents gas from diffusing into the water.
