Expansion Vessels
Potable water expansion vessels for use on domestic and commercial sealed chilled and hot water systems.
Heating Expansion Vessels for use on domestic and commercial hot water systems. Each vessel is factory-tested before leaving the factory.
For sealed heating (acc. to EN12828) and cooling installations.
When the temperature in the installation rises, the system water will expand. The ‘expansion water’ is stored temporarily in the expansion vessel to keep the pressure in the installation at the correct level. Each vessel is factory-tested.
Assumptions Made: 2.8 bar vessel pre-charged, 3 bar pressure reducing valve, Incoming cold water mains at 10°C, 6 bar safety relief valve
