Mikrofill XP 19L Expansion Vessel for Sealed Heating Systems

The Mikrofill XP 19L Expansion Vessel is a compact, high-performance solution for managing thermal expansion in sealed heating and pressurised water systems. As water temperature increases, the Mikrofill XP 19L Expansion Vessel absorbs the additional volume, helping to maintain stable system pressure. As a result, it protects boilers, pumps, valves, and pipework while improving the efficiency and reliability of the entire system.

Manufactured from durable steel and fitted with a premium butyl diaphragm, this expansion vessel delivers dependable performance and a long service life. It arrives pre-charged to 12 Bar, allowing for quick installation and reliable operation. Since this model is supplied without a mounting bracket, it is ideal for installations with existing mounting arrangements or floor-mounted applications.

Furthermore, the 19-litre capacity makes it suitable for a wide range of domestic, commercial, and light industrial heating systems. In addition, its robust construction helps reduce pressure fluctuations, which minimises wear on essential heating components. Consequently, your system can operate more efficiently while requiring less maintenance over time.

Whether you are replacing an existing vessel or installing a new sealed system, the Mikrofill XP 19L Expansion Vessel provides dependable pressure management, easy installation, and long-lasting durability.
