The Reflex Refix DD 8/25 flow-through expansion vessel for drinking water is designed for hot water heating and distribution systems according to DIN 1988. It maintains stable pressure in the installation, compensates for volume changes during heating, and prevents frequent opening of the safety valve, thereby reducing heated water losses and saving fittings and pipes.

The water is stored behind a membrane in a completely separate space with a hygienic internal coating according to KTW, preventing corrosion of the vessel and deterioration of drinking water quality. The compact design with a stainless steel G3/4" connection allows easy installation to water heaters and small booster stations.
