Description
The Xylem-Bell & Gossett 189579 Bladder is an elastic internal component that provides pressure separation in expansion tanks in fluid circulation systems. It adds the B200 tank compatibility with sealed bladder construction to separate the air and water in the tank to allow the thermal expansion and contraction of the fluid during operation. It works in HVAC systems, such as hydronic heating and cooling elements, where pressure stabilisation is needed to prevent damage, to piping and equipment. It helps to stabilise the, fluid circulation and the balance of the system pressure by absorbing the changes.
