Series PTA expansion tanks are ASME rated, pre-charged diaphragm-type vessels designed to absorb the forces of expanding water and protect a potable water system from pressure build up. The FDA approved heavy duty butyl diaphragm and polypropylene liner (sizes PTA-5 through PTA-210V) or replaceable FDA approved full acceptance butyl bladder (sizes PTA-447 through PTA-457) completely isolates the water from the steel shell. All units include an integrated bladder integrity monitor.
