Mikrofill

The Mikrofill MikroPro 1000/2 is a space saving, compact sealed system pressurisation bundle for LPHW/CHW applications. It pairs the Mikrofill 3 advanced direct-type pressurisation unit (cold fill up to 4.7 Bar), a pair of MikroPro 500 Ltrs (6 Bar) expansion vessels, and a ¾" quick-fit service valve.

The direct-fill design connects to the mains/boosted supply to automatically fill and top-up the system. A digital control system with LCD display simplifies setup, while a high-flow WRAS-approved fill valve, low energy use (10 Watts standby / 30 Watts running) and a fill volume indicator support efficient operation and water-treatment calculations.

• Direct-type pressurisation cold fill to 4.7 Bar
• MikroPro dual expansion vessels, rated to 6 Bar
• Automatic system fill & top-up with LCD interface
• WRAS-approved high-flow fill valve

The MIKROFILL MAXI UHP AP 180 Pressurisation Unit is a high-capacity, floor-standing solution for sealed LPHW, CHW, refrigeration and industrial cooling systems. Single (duty) or twin (duty/standby) pump configurations pair with Ai100 digital control for precise, reliable pressure management.

BMS-ready as standard, MAXI UHP AP integrates via Modbus RTU and 4 programmable volt-free relays, while Category 5 backflow protection (Type AB air gap with weir overflow and warning pipe) safeguards water quality. A compact, robust, powder-coated steel enclosure with adjustable feet simplifies installation and commissioning.

• Sealed systems up to 300,000 Ltrs
• Cold fill options: approx. 3.9–8.0 Bar (model dependent)
• Ai100 microprocessor control with full status indication
• BMS integration: Modbus RTU + 4 volt-free relays

Designed for long-term performance, MAXI UHP AP features self-diagnostic electronics, leak detection (frequency-of-starts alarm), and high-quality peripheral pump(s) to keep large systems running at peak efficiency.
