Bladder expansion tanks from Bell & Gossett contain a balloon-like bladder or rubber membrane within the shell that can be replaced when required. Pre-charged bladder expansion tanks from Bell & Gossett absorb thermal expansion forces in hydronic heating and cooling systems. Their rubber membranes isolate the air from the system fluid, preventing waterlogging, and the pre-charge minimizes the size of the tank.
