The Reflex Refix DD pressure expansion vessel for drinking water is designed for small storage water heaters and domestic drinking water systems. The flow-through design with stainless steel connection meets hygiene requirements for drinking water and prevents water contact with the steel casing of the vessel.

The vessel compensates for volume increase during water heating, stabilizes pressure in the system, and reduces frequent opening of the safety valve, thereby minimizing hot water losses and reducing stress on fittings. It is particularly suitable for smaller water heaters in residential and small commercial buildings.
