Mikrofill 800L Expansion Vessel for Sealed Heating Systems

The Mikrofill 800L Expansion Vessel is a high-capacity pressure vessel engineered to manage thermal expansion in sealed heating and hot water systems. As water temperatures rise, the Mikrofill 800L Expansion Vessel absorbs the increased water volume, helping to maintain safe and consistent system pressure. As a result, it protects boilers, pumps, valves, and pipework from excessive pressure while improving overall heating system efficiency.

Manufactured from heavy-duty steel and fitted with a premium butyl diaphragm, this expansion vessel is built for dependable, long-term performance. It comes pre-charged to 6 Bar, allowing for quick installation and reliable operation. Since this model is supplied without a mounting bracket, it is ideal for floor-mounted installations or systems that already have suitable support arrangements.

Furthermore, the 800-litre capacity makes this vessel an excellent choice for commercial buildings, industrial facilities, district heating systems, and other high-demand applications. In addition, it helps reduce pressure fluctuations that can shorten the lifespan of heating equipment. Consequently, boilers, pumps, and valves operate more efficiently while maintenance requirements are reduced.

Whether you are replacing an existing expansion vessel or installing a new heating system, the Mikrofill 800L Expansion Vessel delivers reliable pressure management, durable construction, and outstanding long-term performance.

Why Choose the Mikrofill 800L Expansion Vessel?

Selecting the correct expansion vessel is essential for maintaining a safe and efficient heating system. The Mikrofill 800L Expansion Vessel offers dependable pressure control while helping to protect valuable heating equipment from thermal expansion.

Moreover, its heavy-duty steel construction and premium butyl diaphragm ensure excellent durability under demanding operating conditions. Because it is specifically designed for sealed heating systems, it provides reliable performance for commercial and industrial applications where consistent pressure management is essential.
