Thermal Expansion Absorbers
DXT Series
The DXT Series diaphragm thermal expansion tank is designed for use in domestic system installations for sanitary hot water applications. The tank is installed in systems equipped with a backflow preventer or as an add-on to direct or indirect water heaters. The tank’s function is to absorb the increased volume of water which results from the heating process, thereby keeping the system’s pressure below the relief valve settings. The tanks are available in sizes from 2 to 21 gallons. The heavy duty butyl diaphragm is designed to provide a permanent separation of the water from the air cushion. The exclusive plastic liner and stainless steel connection ensures effective protection against corrosion and allows the product to be safely used in domestic hot water systems. The installation of a DXT tank in any of the above mentioned systems reduces the system’s operating costs and prevents unnecessary relief valve operation. Unit is NSF61 and IAPMO certified.
