Mikrofill MikroPro 800/2 Pressurisation Set – With 2 × 400 Litre Vessels – Service Valve Included

The Mikrofill MikroPro 800/2 Pressurisation Set is a complete pressure management solution for sealed heating and chilled water systems. The Mikrofill MikroPro 800/2 Pressurisation Set combines the advanced Mikrofill 3 direct-type pressurisation unit, two 400-litre MikroPro 6 Bar expansion vessels, and a 1-inch quick-fit service valve into one convenient package. As a result, installers receive a fully integrated solution that simplifies installation while providing dependable pressure control.

Unlike conventional pump-operated units, the Mikrofill 3 connects directly to the building’s mains or boosted water supply and fills the system without using an internal pump. Furthermore, it automatically monitors and maintains system pressure, helping to improve efficiency while reducing energy consumption. The unit operates with a maximum cold fill pressure of 4.7 Bar, making it suitable for a wide range of commercial LPHW and CHW applications.

In addition, the supplied 2 × 400-litre MikroPro expansion vessels absorb thermal expansion and maintain stable operating pressure throughout the system. Consequently, boilers, pumps, valves, and associated pipework remain protected from unnecessary pressure fluctuations, helping to extend equipment life and improve overall system reliability.

The package also includes a 1-inch quick-fit service valve, allowing easier servicing and maintenance when required. Moreover, the compact design helps reduce installation time while providing a professional, factory-matched pressure management solution.

Whether you are installing a new commercial heating system or upgrading an existing plant room, the Mikrofill MikroPro 800/2 Pressurisation Set delivers reliable performance, efficient pressure control, and long-term durability.
