Mikrofill

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.

The MikroPro Expansion Vessels range serves almost any LPHW or CHW system, with capacities from 8500 Ltrs. Models up to 25 Ltrs are wall-mounted, while 35 Ltrs and above are floor-standing. This comes with a wall mount bracket.

With an 18Ltr capacity with an operating pressure of 3 Bar., this is built for performance, reliability and compliance, MikroPro vessels are PED 97/23/EC compliant, rated to a maximum operating temperature of 70 C, and available with pressure ratings of 3 Bar (835 Ltrs) or 6 Bar (501000 Ltrs). Threaded connections and a durable powder-coated finish simplify installation and maintenance.

• Capacities: 8500 Ltrs
• Mounting: wall (≤25 Ltrs) or floor (≥35 Ltrs)
• Ratings: up to 70 C, 36 Bar (model dependent)
• Applications: heating and chilled water systems

A versatile, robust choice for commercial and large domestic systems requiring stable expansion capacity and long service life.

The Mikrofill Dosing Pot - 18 Litres - 10 Bar. is a wall-mounted chemical dosing vessel for adding corrosion inhibitors or anti-freeze into closed LPHW and CHW systems. Simple to operate and easy to flush clean, all system connections can be isolated via integrated ball valves.

Fabricated from AISI 304 Stainless Steel with welded construction and a tundish, each unit is compliant with PED 2014/68/EU. Sizes span 3.550 Ltrs with robust BSP connections, a maximum working pressure of 10 Bar and a maximum operating temperature of 90 C.

• Wall-mounted stainless construction for durability and hygiene
• Isolatable connections for safe, controlled dosing
• Fast flush and clean to minimise downtime
• PED 2014/68/EU compliant for assured quality

Standard BSP connections and supplied valves/fittings simplify installation across commercial heating and chilled water systems.
