Amtrol Extrol In-Line EX Series

EXTROL^{®
Hydronic Expansion Tanks}

AMTROL designed and patented the first EXTROL expansion tank in 1954, redefining hydronic heating systems. For five decades their unique, pre-pressurized, diaphragm design EXTROL has been the world's leading expansion tank. EXTROL was designed to control system pressure and help reduce energy consumption of heating and chilled water operations. Over fifty years later, Extrol is still the world's leading expansion tank and still proudly made in the USA.
