About Maxi-Cool | UK-Manufactured Server Rack Cooling

Maxi-Cool is a range of precision server rack cooling systems designed, engineered and manufactured in the UK. Engineer James Garson founded Maxi-Cool in 2014 to solve the problem of cooling the heat generated by servers inside a single rack without the need for a dedicated server room. Maxi-Cool is available in a range of integrated server rack cooling solutions — the Halo TM5, the Gemini split system, and the Mercury ventilated cabinet range.

Our Mission

The Maxi-Cool mission is to create energy-efficient server cooling that achieves precision cooling in each cabinet. Our vision is to design, manufacture and support sustainable cooling solutions that support the drive toward net zero. Using significantly less energy than conventional server-room air conditioning, Maxi-Cool enables businesses to run powerful servers anywhere.  Every Maxi-Cool product is patented, UK-manufactured, and backed by a 12-month parts-and-labour warranty.

About James Garson

James Garson studied engineering at Birmingham University before spending 13 years with a global machine tool builder. In 2002, he founded Maximise Engineering Services Ltd, specialising in machine tools, automation and robotics.

The idea for Maxi-Cool grew directly from conversations with Maximise customers — many of whom manufacture server racks and cabinets — who were struggling to keep their equipment cool outside a traditional data centre environment. James recognised that the problem wasn’t the servers themselves, but the lack of a practical, energy-efficient cooling solution designed specifically for the rack.

He set about designing one. The result was Maxi-Cool — a patented, self-contained server rack cooling system that combines engineering precision with elegant, functional design. Every product in the Maxi-Cool range reflects James’s commitment to UK manufacturing, his engineering background, and his belief that the best solution to a complex problem is usually a simple, well-designed one.

Why Choose Maxi-Cool?

MAXI-COOL® has been built on engineering excellence crafted through unstinted dedication to quality, innovation and a constant objective to serve the European server market.

Cost-Effective
Maxi-Cool systems use significantly less energy than conventional server room air conditioning — cooling only the equipment inside the cabinet, not the whole room. Most units run from a standard 13-amp plug, with power consumption of less than 7 amps at full load.
Versatile
Maxi-Cool products are designed for environments where conventional air conditioning is impractical or not permitted — including listed buildings, rented offices, tower blocks, factories, and any location where an external condenser is not possible
Quick to Install
Most Maxi-Cool systems are operational within a couple of hours of delivery. No building work, no specialist engineer, and no external condenser required — just a standard wall socket and a suitable cabinet location.
Eco-friendly
By cooling only the equipment inside the cabinet rather than the whole room, Maxi-Cool systems reduce energy consumption and carbon footprint significantly compared to equivalent server room air conditioning. All units are recyclable at end of life.

Fully Customisable Server Rack Cooling

MAXI-COOL® cabinets can be manufactured in any RAL colour of your choice. We can also accommodate any company logo requirements, taking into account your corporate brand guidelines.
