PUMPS & PRESSURISATION Expansion Vessels


Heating 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 problem free connection.


• The fixed bag-type diaphragm prevents the water from coming into contact with the bare steel of the vessel.


• Nitrogen gas filling for longer maintenance of pre-pressure. Technical Specifications


• Maximum working pressure: 6 Bar • Vessels in accordance with EN13831 • Min. / max. temperature diaphragm: -10 / 70 °C • In accordance with Pressure Equipment Directive 2014/68/EU


• Suitable for systems with a maximum system temperature of 120 °C


• Diaphragm: EPDM • All welded construction & Zinc plated flange


• Suitable for addition of glycol-based antifreeze up to 50% and ethanol-based antifreeze up to 30% • Red (RAL 3002) epoxy powder coating • 35 – 1000L as standard come equipped with legs
