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 the EX is still the world?s leading expansion tank and is proudly made in the USA! The EX in-line boiler system expansion tank collects the expanded water as system temperatures rise which reduces potentially dangerous pressure build-up. Ideal for residential applications, the EX is equipped with a 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. The EX-1500-100 also includes an air purger that separates water from air, as well as an automatic air vent that eliminates system air. This keeps your whole system running smoother, quieter, and more effectively.
All EX thermal expansion tanks are made in the USA.
Heavy Duty Tank
From the deep drawn steel tank to the water-tight reservoir for expanded water, this thermal expansion tank is constructed for maximum strength and efficient energy consumption.
The included automatic air vent eliminates system air, keeping your system running smoothly.
The air purger separates air from water before sending the water into the expansion tank and air to the vent.
