Mikrofill Pressurisation Units
Mikrofill Pressurisation Units are advanced systems designed to maintain the pressure in heating and chilled water systems without the use of traditional pumps. The Mikrofill 3, in particular, is noted for being a "pumpless" pressurisation unit, which connects directly to a building's incoming mains or boosted water supply. This design allows it to fill systems efficiently while consuming minimal energy—only 10 watts per hour on standby and 30 watts per hour during operation.
Key Features
- Pumpless Design: Unlike conventional pump-type units, Mikrofill units do not utilise pumps, simplifying installation and reducing energy consumption.
- Direct Connection: They are designed to fill low-pressure hot water (LPHW) and chilled water (CHW) systems directly from the mains supply, making them versatile for various applications.
- Energy Efficiency: The Mikrofill 3 is highlighted as the most energy-efficient unit in its category, suitable for systems of any size.
- Electronic Pressure Management: These units incorporate advanced electronic systems for managing pressure, ensuring optimal performance and reliability.
Mikrofill units are particularly beneficial in settings where energy efficiency and space-saving designs are prioritised, making them a popular choice in modern building services.
