Closed Expansion Tank is an element of heating system which is correlated to pressure systems in power house. Bokharsazeh closed expansion tanks are provided to control water volume expansion, due to temperature increase, in installation systems, operating pressure in closed expansion tanks is equal to boilers operating pressure in powerhouse. This must be especially considered in designing process.

Advantages of closed expansion tank comparing to open one

  • Reduction of heating loss due to no connection with cold environment
  • Piping reduction
  • Tolerance of pressure over 3 bar
  • No corrosion due to contact with air oxygen
  • Developing a head to increase or reduce the water velocity in pipe when boiler valves are open or closed
  • Reduce effects of water hammer

All of Bokharsazeh steam boilers receive Iranian Standard Plaque.
