The Mikrofill MIDI SPU135 Pressurisation Unit is a versatile pressurisation unit for larger domestic and light commercial sealed systems — covering LPHW, CHW, refrigeration and industrial cooling. Floor or wall mountable.

Its compact design allows wall or floor mounting for fast installation and commissioning. An advanced digital control system with automated fill and top-up ensures precise pressure management, supported by a high-flow, KIWA-approved fill valve and flexible connection options.

• Mid-range power for systems up to 150,000 Ltrs
• Digital control with LCD display
• Automated system fill & top-up
• Compact footprint — wall or floor mount

With an 8 Ltrs integral tank and cold fill capability to 4.1 Bar, inlet and outlet can be configured left or right using the supplied flexible hoses. Category 5 backflow protection (Type AB air gap) adds safety and compliance.

The Mikrofill MAXI AP 280 Pressurisation Unit is a high-capacity, floor-standing solution for large domestic, commercial and industrial sites. It maintains stable pressure across sealed LPHW, CHW, refrigeration and industrial cooling systems.

Quick to install and commission, MAXI AP 280 uses an advanced microprocessor-controlled platform with Ai100 technology for accurate, efficient management. Choose single or twin-pump configurations with intuitive digital controls and real-time status.

• BMS-ready: Modbus RTU plus 4 programmable volt-free relays
• Cold fill options: up to 3.9“8.0 Bar (model dependent)
• Protection: Category 5 backflow with Type AB air gap
• Robust build: powder-coated steel casing with adjustable feet

Self-diagnostics and leak detection (frequency-of-starts alarm) support long-term reliability, while enhanced models integrate seamlessly with Building Management Systems.
