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 world?s leading expansion tank manufacturer. The SE solar system expansion tank collects expanded water as system temperatures rise, reducing potentially dangerous pressure build-up. Ideal for residential applications, the SE-15 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. It is designed to specifically work with high efficiency solar systems and the SE is suitable for use with glycol.
Heavy Duty Tank
From the deep drawn steel tank to the water-tight reservoir for expanded water, this expansion tank is constructed for maximum strength and efficient energy consumption.
Eliminates Wasted Energy
Expanded water caused by thermal expansion is collected by the SE tank which returns the water back to your system which preventing faucet drips, intermittent toilet fill, and pressure relief valve discharge.
Protection for Your System
SE expansion tanks are designed to protect your water heater, fixtures, and appliances by preventing dangerous pressure build up.
