More about this product
Overview
The Contraflex expansion vessel is intended for use on sealed heating and chilled systems.
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.
The thread of the system connection is uncoated, ensuring problem free connection. The fixed bag-type diaphragm prevents the water to come in contact with the bare steel of the vessel. Nitrogen gas filling for longer maintenance of pre-pressure.
Suitable for systems with a maximum system temperature of 120 °C. Min. / max. temperature diaphragm: -10 / 70 °C.
Suitable for addition of glycol-based anti-freeze up to 50%.
Suitable for addition of ethanol-based anti-freeze up to 30%.
In accordance with Pressure Equipment Directive 2014/68/EU.
