The Reflex Refix DE 300/10 pressure expansion vessel is designed for potable and utility water distribution, pressure boosting systems, and hot water heating according to DIN 1988. Thanks to the membrane in the form of a bladder, the vessel itself is not in direct contact with the medium, which significantly increases its resistance to corrosion and extends its lifespan.

The vessel, with a nominal volume of 300 l and a maximum operating pressure of 10 bar, operates with a prescribed pre-charge pressure of 4 bar and is equipped with a threaded connection G 1¼". The robust steel construction with an epoxy coating and approval according to directive 2014/68/EU ensures safe operation even in more demanding applications. The non-flow design without shut-off and drain valves allows for easy installation and minimal maintenance requirements.
