Construction: steel, welded tank divided by a flexible membrane.

Upper part is filled with pressured gas and is equipped with a pressure regulation valve. Lower part of the tank is filled with water flowing through it from a heating system. The membrane stabilises pressure inside the system by adjusting to changes of water volume.

Pressurised expansion vessel is a protective element for domestic hot water systems that compensates changes of liquid volume at the temperature changes. 


Principle and functioning of a pressurised expansion vessel:

  • compensation of changes of liquid volume at temperature changes
  • maintenance of water pressure in heating systems for specific parameters
  • optimization of conditions for heat distribution without heat loss
  • autogenous water supplementation in case of losses caused by minor leakages

Pressure expansion tanks are delivered with constantly set-up pressure of the gaseous part. This part is set-up to the corresponding operation pressure during the installation of the expansion tank in the heating system.
