Server Cooling Issues? – An innovative, energy efficient solution is here.

The Maxi-Cool system provides 4 kW of cooling power integrated within a single standard stack rack. Precision engineered in the UK, Maxi-Cool is a flexible, cost effective alternative to air conditioning.

Why choose MAXI-COOL® for your server cooling?


    MAXI-COOL® technology eliminates hot-spots and keeps servers working faster and with greater reliability than conventional server cooling methods.


    MAXI-COOL® takes the form of a neat cabinet with an array of design options, it is quiet to run with no need for air-conditioning, making it an ideal solution for offices or listed buildings without dedicated server rooms.


    MAXI-COOL® is a self-contained cooling unit, therefore it’s cheaper and more environmentally efficient to run. It avoids the Health & Safety issues of maintaining air-conditioning systems and addresses dust problems that are common place with server rooms.


    Lower power consumption than conventional server-cooling, Maxi-Cool reduces both your carbon footprint and your running costs.


    MAXI-COOL® provides enough efficient cooling for the cabinet to be at full server storage capacity with no drop in performance levels.

How Maxi-Cool works? Air flow cooling

How does MAXI-COOL® work?

Here’s how the MAXI-COOL® unit keeps your servers working faster and more reliabily than conventional cooling:

  1. Cooling air comes in from room.
  2. Cold air from MAXI-COOL® is blown down into server air intakes.
  3. Hot air from the servers is blown into the rear of the cabinet and drawn into the MAXI-COOL® to be cooled and returned to the front of the servers.
  4. Waste heat extracted from the cabinet is expelled as warm air from the rear of the MAXI-COOL® unit.

Thermal image of a server cabinet with MAXI-COOL®

The left-hand side of the image shows the Maxi-Cool collecting the warm air at the back of the server cabinet for extraction. The right-hand side of the image shows the cooler air, (approx. 22C - ideal operating temperature) entering the servers at the front of the cabinet. Note the uniform temperatures and absence of any ‘hot spots’ within the cabinet.

The equipment, at near max-capacity, is generating 4kW of heat. Dark blue areas represent 18C, white areas 27C.

Frequently asked questions

Does it take long to install?

The unit is typically installed in a matter of hours by our engineers. All you need to provide is a power point or UPS source.

Does it need sound proofing?

No. The unit operates very quietly, typically less than 65db.

Does it need external cooling?

No, as long as the room has air flow, the cooler will work.

Can I specify colours and cabinet types?

Yes. We will accommodate requirements as much as possible taking into account your corporate brand guidelines.

Does MAXI-COOL® need much maintenance?

No. The air filter needs to be kept clean. This is a very simple process. In addition, yearly system checks and maintenance agreements are available.

About Maxi-Cool

As an innovative engineering company, Maximise Engineering Services Ltd is always interested in identifying problems and finding solutions for its customers.  The development of 'Maxi-Cool' reflects this interest.   

Conversations with other engineering businesses involved with data centre development identified an on going and previously unresolved issue with the cooling of severs in small numbers and in confined spaces where traditional air conditioning was not suitable.

As a response to these server cooling issues Maximise Engineering Services Ltd has developed a cooling system that is integrated into a server cabinet. The aim has been to create a cooling system that would provide a high level of cooling capacity but be efficient enough to allow the racks to be fully stocked and quiet enough for people to work alongside. 

Maxi-Cool has been designed, engineered and manufactured in East Anglia, UK.

News: My Server Cooling ‘Aha’ moment

Having worked with machine tools for 25 years, I’ve always been interested in what could be made to address various problems in engineering. It was after a conversation with a customer and rack manufacturer in 2012 about data centre cooling, however, that I became interested in helping small and medium sized offices with their server cooling. It was that classic ‘aha’ moment inventors have!
