Refix DE 200 Diaphragm Expansion Vessel 200L

Refix DE 200 Diaphragm Expansion Vessel 200L

The Refix DE 200 diaphragm expansion vessel is engineered to provide reliable pressure control and volume compensation in closed water and heating systems. In pressurized systems, water expands as temperature or pressure increases. Without a correctly sized expansion vessel, this expansion can cause excessive pressure rise, frequent safety valve discharge, premature component wear, and long-term system instability. The Refix DE 200 is designed to absorb these volume changes efficiently, ensuring stable operating pressure and protecting system components.
