Mikrofill Digital Pressurisation Unit Maxi Plus AP 240 – Twin Pump – 73 Ltr/min – Single Phase – Right-hand Entry

The Mikrofill Digital Pressurisation Unit Maxi Plus AP 240 is engineered to provide intelligent pressure management for sealed heating, chilled water, refrigeration, and industrial cooling systems. It continuously monitors system pressure and automatically restores the correct operating pressure whenever required. As a result, boilers, chillers, pumps, valves, and pipework remain protected while the entire system operates safely and efficiently.

Designed for demanding commercial and industrial environments, this model features twin pumps, a 73 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 service while minimising downtime during maintenance or unexpected pump issues.

In addition, the advanced digital controller incorporates 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 operating performance more effectively, reduce maintenance requirements, and improve long-term system reliability.

The unit also features 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 allows seamless integration with Building Management Systems (BMS). This enables remote monitoring, alarm reporting, and enhanced control across commercial plant rooms.

Built with a heavy-duty powder-coated steel enclosure, the unit is designed for continuous operation in demanding environments. Whether you are replacing an existing pressurisation unit or installing a new HVAC system, the Mikrofill Digital Pressurisation Unit Maxi Plus AP 240 provides dependable pressure control, intelligent monitoring, and long-lasting performance.
