High-quality membrane expansion vessel suitable for closed heating and cooling installations. The flexible membrane absorbs excess water pressure caused by thermal expansion. Thereby, the pressure of the system remains constant. The vessel is filled with nitrogen gas to protect it against corrosion and pressure losses. Each vessel is factory-tested on tightness and pre-charge pressure. The membrane made of SBR rubber is approved for a glycol content of up to 50% in the water. The vessel is equipped with 3 stable, welded-on support feet.
