In 1954 Amtrol invented the first expansion tank to control pressure build-up and energy consumption in heating and chilled water systems. More than 50 years later they are still the worlds leading expansion tank manufacturer. The FT expansion tank collects the expanded water as system temperatures rise which reduces potentially dangerous pressure build-up. Ideal for residential applications the FT is equipped with an automatic fill valve 100 percent tested sealed air cushion water-tight reservoir air stem for pre-charge adjustment and a deep drawn steel tank all ensuring the reliability of your tank over the long haul. Product Features USA Made All FT expansion tanks are made in the USA.
