The expansion and deaeration tank manufactured by Enthalpy is a 2-in-1 unit, serving both for oil expansion and for deaeration. A special advantage of the Enthalpy expansion and deaeration tank is that it compensates for oil expansion and makes up for oil losses without mixing the cold oil in the expansion tank with the hot oil circulating in the operating system. This keeps the oil in the expansion tank at a low temperature, reduces heat loss and extends the service life of the thermal oil.

The deaerator efficiently removes oxygen and other dissolved gases from boiler feedwater without the use of chemicals.

Pressure vessels and tanks, including steam headers (manifolds), are equipment used to contain, store and transport liquids or gases at pressures above atmospheric pressure.
