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.
