Mikrofill XP 80L 10 Bar Expansion Vessel

The Mikrofill XP 80L 10 Bar expansion vessel is engineered to manage thermal expansion in sealed heating and pressurised water systems. As water temperatures rise, the vessel absorbs the increased volume and maintains stable system pressure. As a result, it helps protect boilers, pumps, valves, and pipework while improving the overall efficiency and reliability of your heating system.

Constructed from heavy-duty steel and fitted with a premium butyl diaphragm, this expansion vessel is built to perform in demanding environments. It comes pre-charged to 10 Bar, allowing for quick installation and dependable operation. Since this model is supplied without a mounting bracket, it is ideal for floor-mounted installations or systems with existing mounting arrangements.

Furthermore, the 80-litre capacity makes this vessel an excellent choice for larger domestic properties, commercial buildings, and industrial heating systems. In addition, it helps minimise pressure fluctuations that can increase wear on critical heating components. Consequently, your system can operate more efficiently while reducing maintenance costs and extending equipment life.

Whether you are upgrading an existing installation or fitting a new sealed heating system, this MikroPro XP expansion vessel provides dependable pressure management, durable construction, and long-term performance.
