Therm-X-Trol Expansion Tanks

Amtrol Therm-X-Trol series expansion tanks are thermal expansion tanks used in residential and commercial potable hot water heating systems. These tanks absorbs the expanded hot water produced by the water heater and prevents frequent discharge of the pressure relief valve. Therm-X-Trol tanks are factory charged with 40 psi pressure and are NSF approved for use with potable water applications. We also stock an extensive selection of Well-X-Trol well expansion tanks.
