Maxi-Cool Gemini

Gemini Server Cooling Unit

Our new Maxi-Cool GEMINI system is a flexible server cooling system that is a significant addition to our range of patented and proven enclosure cooling technology. The Maxi-Cool Gemini brings Maxi-Cool technology to the creation of micro datacentres for small and medium-sized installations. With powerful cooling starting at 5kW, you can configure your own data centre on a modular basis without the need for cold and hot aisle containment or raised floors. Maxi-Cool Gemini is suitable for spaces that are too dusty and unfit for conventional systems.

Each Maxi-Cool Gemini module gives active precision cooling that simply cools the rack and not the room. The Maxi-Cool Gemini is efficient server cooling that uses less energy for the same amount of server cooling as conventional air conditioning. It is a sustainable alternative to traditional air conditioning in server rooms with the advantage of lower running costs. Additionally, the Maxi-Cool Gemini, as part of the Maxi-Cool range, is recyclable and returnable at the end of life.

Maxi-Cool Gemini is fully customisable allowing for bespoke cabinet layouts and specific cooling capacities. There is an option for a built-in backup ventilation system that provides a backup cooling capacity. The Maxi-Cool Gemini is a scalable and agile server cooling solution that has a modular format allowing you to create your own data centre that can be modified over time as your requirements change. There are a number of security options and paint finishes available and the Maxi-Cool Gemini is available in a travel case version, making it fully mobile. Maxi-Cool Gemini is sold with 12 months parts and labour warranty and service contracts are available.


The Gemini cabinet cooling system maximises efficiency and minimises power consumption by only cooling the cabinet.

Mobile versions in flight cases are available, using rugged quick-fit connections between the cabinet and the condenser. We can supply cabinets of all sizes and specifications with cooling systems of 5kW capacity and upwards.

Maxi-Cool GEMINI allows you to configure the exact micro data centre that you need. As the system recycles the air inside the cabinet it can be used in environments where ambient air is unfiltered.

How It Works

The Gemini system feeds cool air to the intakes of all the servers, eliminating the possibility of hot spots inside the cabinet. As the air passes through the servers it cools them and absorbs their rejected heat. This heated air passes through an evaporator where it is cooled down and fed back to the servers intakes and the cycle is repeated. It is a closed loop, so dirt and moisture are kept out of the cabinet. Meanwhile, the coolant in the evaporator, having been heated up by the air is passed to an external condenser where it is cooled down and returned to the evaporator to repeat the process. As the condenser is separate from the cabinet, waste heat from the cabinet can be rejected into a room or space separate from the cabinet.
