Mikrofill XP 100L 10 Bar Expansion Vessel

The Mikrofill XP 100L 10 Bar expansion vessel is designed to control thermal expansion in sealed heating and pressurised water systems. As water temperatures increase, the vessel absorbs the additional volume and maintains stable system pressure. As a result, it helps protect boilers, pumps, valves, and pipework while improving the efficiency and reliability of your heating system.

Constructed from heavy-duty steel and fitted with a premium butyl diaphragm, this expansion vessel delivers dependable performance in demanding environments. It comes pre-charged to 10 Bar, making installation straightforward and ensuring reliable 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 100-litre capacity makes this model an excellent choice for larger domestic properties, commercial buildings, and industrial heating systems. In addition, it helps reduce pressure fluctuations that can place unnecessary strain on heating equipment. Consequently, maintenance requirements are reduced, and the lifespan of boilers, pumps, and associated components can be extended.

Whether you are replacing an existing expansion vessel or installing a new sealed heating system, this MikroPro XP expansion vessel offers dependable pressure management, durable construction, and long-term reliability.
