What is an Expansion Tank?

Expansion Tank Operating Temperatures

There are two different chambers in heat exchanger systems. The hot fluid entering one of these chambers exchanges heat with the cold fluid entering the other chamber without mixing. During this heat exchange, the cold fluid heats up and begins to expand volumetrically. The chamber where this expansion occurs is called the expansion tank. This tank should be preferred with a durability that can withstand the pressure in high-capacity heat exchangers.

The volumetrically expanding fluid will cause a pressure increase. Since this pressure can lead to serious problems, factors such as the material type and thickness of the expansion tank should be taken into consideration.

Types of Expansion Tanks

 If we give some information about the operating temperatures of the expansion tank, it is foreseen that expansion tanks will operate between 95 ˚C and 70 ˚C when they are manufactured. The standard fluid temperature is an average of 80 ˚C. Using the expansion tank above this temperature may cause various problems. Leaks may occur from the valves due to increased pressures, or water insulation may fail. The minimum temperature usage value, as well as the maximum value, is an average of 10 ˚C. It is not recommended to use it below this temperature. Buffer tanks are recommended for lower temperature values.

Expansion tanks are divided into two types; 

  • Open expansion tanks
  • Closed expansion tanks

There must be a fluid pressure gauge on the expansion tanks. The installation of expansion tanks requires expertise. Therefore, you should definitely get support from experts when installing such systems.
