The Reflex Refix DD 2 is a flow-through membrane pressure expansion vessel designed for heating systems, water supply, and boosting drinking water pressure. Thanks to the High-Flow star and the included 3/4" T-piece, it ensures high flow capacity and reliable pressure stabilization in the distribution system.

The vessel is equipped with a non-replaceable bladder membrane that meets KTW-C and W270 requirements for drinking water. The internal and external surface treatment according to KTW-A protects parts in contact with water against corrosion. The design complies with DIN EN 13831 and the vessel is tested according to DIN 4807 T5, with DVGW and PED 2014/68/EU approval.
