Mikrofill Digital Pressurisation Unit Maxi Plus UHP AP 280 – Twin Pump – 38 Ltr/min – Single Phase – Right-hand Entry

The Mikrofill Digital Pressurisation Unit Maxi Plus UHP AP 280 delivers intelligent pressure management for sealed heating, chilled water, refrigeration, and industrial cooling systems. It continuously monitors operating pressure and automatically restores the correct level whenever required. As a result, boilers, chillers, pumps, valves, and associated pipework remain protected while the entire system operates safely and efficiently.

Designed for demanding commercial and industrial environments, this model features twin high-pressure peripheral pumps, a 38 Ltr/min maximum flow rate, a 230V single-phase electrical supply, and a right-hand pipe entry configuration. Furthermore, the twin-pump arrangement provides automatic duty and standby operation, ensuring continuous system availability while reducing downtime during maintenance or unexpected pump faults.

In addition, the advanced digital controller includes a large LCD graphic display, automatic filling and top-up functions, leak detection monitoring, dry-run protection, and intelligent self-diagnostic electronics. Consequently, engineers can monitor system performance more efficiently, reduce maintenance time, and improve long-term operational reliability.

The unit also incorporates Category 5 backflow protection with a Type AB air gap to comply with current water regulations. Moreover, integrated Modbus RTU communication together with programmable volt-free relay outputs enables seamless integration with Building Management Systems (BMS). This allows remote monitoring, alarm reporting, and enhanced operational control for large commercial plant rooms.

Manufactured with a heavy-duty powder-coated steel enclosure, the unit is built to withstand demanding operating environments while providing dependable long-term performance. Whether you are replacing an existing pressurisation unit or specifying equipment for a new HVAC installation, the Mikrofill Digital Pressurisation Unit Maxi Plus UHP AP 280 delivers accurate pressure control, intelligent monitoring, and outstanding reliability.
