Currently available in five sizes, from 4 to 25l, the new pressure expansion vessel with fixed gas filling features a high-quality bellows membrane that prevents the system water from coming into contact with the sheet metal wall of the vessel. This design helps to reduce corrosion from occurring inside the vessel, and can maintain optimum pressure up to five time more efficiently than expansions vessels with a standard flat membrane.
To make servicing and maintenance easier than ever, the pressure relief valve is located on the front of the unit. Additionally, the vessel comes with a built-in bracket, for ease of installation.
Dave Goodyer, Area Sales Manager, said: “With more installers working on heat pump systems and larger light-commercial projects, it was important that our range of pressurisation units reflected the evolving customer demand. This newest addition to our SpiroExpand range is deigned to really simplify installation and maintenance for the installer, whilst also providing long-lasting results for the end user, at a crucial time when improving efficiency is more important than ever before.”
