Mikrofill 50 Water Pressurisation Package – 50 Litre – 4.7 Bar – Single Phase

The Mikrofill 50 Water Pressurisation Package is a compact and efficient solution for maintaining pressure in sealed heating and chilled water systems. The package includes the Mikrofill 3 direct-type pressurisation unit, a 50-litre MikroPro 6 Bar expansion vessel, and a 1-inch quick-fit service valve. As a result, installers receive a complete pressure management solution that is ready for straightforward installation.

Unlike conventional pump-operated systems, the Mikrofill 3 connects directly to the 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 reliability while reducing energy consumption. The unit consumes only 10 Watts in standby and approximately 30 Watts during operation, making it an energy-efficient choice for commercial installations.

In addition, the integrated Fluid Category 4 backflow protection removes the need for a separate RPZ valve, simplifying installation and reducing maintenance requirements. The large digital display provides clear operating information, while the fill volume indicator assists with inhibitor dosing and water treatment calculations. Consequently, routine servicing becomes quicker and more efficient.

The included 50-litre MikroPro expansion vessel is designed to absorb thermal expansion and maintain stable operating pressure. Together, the pressurisation unit and expansion vessel deliver dependable performance for commercial heating and chilled water applications where reliable pressure management is essential.

Whether you are installing a new sealed system or upgrading an existing installation, the Mikrofill 50 Water Pressurisation Package offers dependable operation, energy efficiency, and long-term reliability.
