Flamco Baseflex Expansion Vessel (Heating)

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. System Connection: G 3/4" M
