Mikrofill 500L Expansion Vessel for Sealed Heating Systems

The Mikrofill 500L Expansion Vessel is a high-capacity pressure vessel designed to manage thermal expansion in sealed heating and hot water systems. As water heats up, it expands, and the Mikrofill 500L Expansion Vessel absorbs this increase in volume to maintain safe and consistent system pressure. Consequently, it helps protect boilers, pumps, valves, and pipework from excessive pressure while improving the overall efficiency of your heating system.

Built from heavy-duty steel and fitted with a premium butyl diaphragm, this expansion vessel delivers dependable performance in demanding environments. It arrives pre-charged to 6 Bar, allowing for quick commissioning and reliable operation from the start. Since this model is supplied without a mounting bracket, it is ideal for floor-mounted installations or systems that already have suitable mounting arrangements.

Furthermore, the 500-litre capacity makes it an excellent choice for large commercial buildings, industrial facilities, and high-demand heating applications. In addition, it helps minimise pressure fluctuations, which reduces wear on critical components and supports more efficient system operation. As a result, maintenance requirements can decrease while the lifespan of your heating equipment increases.

Whether you are upgrading an existing installation or specifying equipment for a new project, the Mikrofill 500L Expansion Vessel offers reliable pressure management, durable construction, and long-term performance you can depend on.

Why Choose the Mikrofill 500L Expansion Vessel?

Selecting the correct expansion vessel is essential for maintaining a safe and efficient heating system. The Mikrofill 500L Expansion Vessel delivers consistent pressure control while helping to protect expensive heating equipment from unnecessary stress.

Moreover, its robust steel construction and high-quality butyl diaphragm provide excellent durability under demanding operating conditions. Because it is designed specifically for sealed heating systems, it delivers dependable performance in commercial and industrial applications where reliability is critical.
