Spirotech SpiroExpand 18 Litre Heating Expansion Vessel 3/4" EVN18

Spirotech Spiroexpand 18L Heating Expansion Vessel 3/4" MI EVN19. Spirotech expansion vessels feature automatic pressure monitoring and will also provide degassed make-up water. The innovative pressurisation solution allows the vessel to provide a total, integrated system care solution. Spirotech is also well known for its reliability and high quality, and its expansion vessels are another example of this. It features a high-quality bellows membrane that prevents water from coming into contact with the sheet metal wall of the vessel. This means that the vessel is great at resisting corrosion and can be more optimal and efficient than a vessel with a standard flat membrane. The pressure relief valve is located on the front facing the side of the unit, making servicing and maintenance easier than ever. They are an important investment as they ensure your system pressure is optimal. This will then lead to much better efficiency and system lifespan. Having optimal system pressure is important, as if the pressure in a system is too high, it could potentially result in leaks and component damage. This expansion vessel has a pre pressure of 0.8 bar and a 18 litre volume.
