1000L CORE Heating Expansion Vessel

For use on domestic and commercial hot water systems with each vessel being 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.

Advantages
• The thread of the system connection is uncoated, ensuring a problem-free connection.
• The fixed bag-type diaphragm prevents the water from coming in contact with the bare steel of the vessel.
• Nitrogen gas filling for longer maintenance of pre-pressure.
