An expansion tank is an essential component
to all heat transfer systems. Heat transfer
fluids expand with an increase in temperature.
Expansion tanks allow for and contain the
increase in volume due to temperature. In
addition, cold expansion tanks provide a “seal”
on the system reducing oxidation of the fluid.
They also add to the net positive suction head
(NPSH) on the inlet to the pump.
Expansion tanks should be sized based on
the amount of thermal expansion of the heat
transfer fluid in the system. The actual size of
the tank should be at least double the anticipated
increase in fluid volume. Tank capacity
should be increased if the process piping is
extensive and contains a significant volume of
fluid. The following tables indicate the typical
tank sizes for most systems.
