DXT Series Expansion
Tanks
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 backflowpreventor 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 setting.
The tanks are available in sizes from
2-13 gallons.
The heavy duty butyl diaphragm is designed
to provide a permanent separation of the water from
the air cushion. The exclusive TOP-PRO® internal
coating ensures effective protection against corrosion
and allows the product to be safely used in sanitary
fresh 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.
