Computer Cooling

Our innovative computer cooling system uses the very latest rear door heat exchanger technology to bring unprecedented levels of energy saving, flexibility, safety and reliability to a data centre set-up.

Heat is taken directly at source via a rear door heat exchanger which gives precision cooling to the entire rear face of the server cabinet and ensures there is no recirculation of hot air.  The heat exchanger utilises water as it’s cooling medium (which is 3500 times more effective than air by volume) and results in an extremely energy efficient and reliable chilled rack environment. The water is chilled to 14ºC, compared to 6ºC with a standard CRAC unit, giving increased performance on the external chillers of 15%. 

The Aqua Vac leak prevention system (patent pending, GB0819910.1) eliminates any danger of water leakage.  The pipe work system works completely under negative pressure with air being continually sucked in. In addition, dew point control prevents any condensation forming on the back of the heat exchanger, even in the height of summer.

In summary, advantages include:

• Considerable power reduction/energy saving - between 68-75% when compared to a typical CRAC unit.  A substantial saving on overheads when you consider that a third of data centre running costs are commonly attributed to refrigeration/air conditioning.
• Direct cooling at heat source.
• Constant vacuum system – no risk of leakage, plus dew point control.
• Versatility – easily expandable and workable with an existing system.  For example, if you have installed newer, additional, more powerful servers to your data room you can add our rear door heat exchangers to individual cabinets to eliminate the increased heat load.  
• Fully compatible – can be retro fitted to any brand of server, you can change rack supplier but still utilise the same cooling equipment.
• Requires no specific site plan and no additional floor space.
• DX version available – works on refrigeration rather than water and uses a condenser rather than chiller system. This is ideal for situations where there is no option to site a chiller externally to a building, for example in central London or if landlord agreements prohibit.

At Aqua Cooling, our staff are fully experienced in specifying cooling solution applications for all different industry sectors, including plastic processing, pharmaceutical, packaging, food and drink, metal finishing and agriculture. As well as supplying the equipment, our engineers can install the complete package, including pumps, tanks, filtration and pipe work.

Our main services include air conditioning, water chillers, adiabatic coolers, air blast coolers, cooling towers, turbocor chillers, free cooling, heat recovery, data centre cooling, server cooling and much more.

Process cooling – industrial equipment designed for any atmospheric conditions, whether it be for desert conditions with temperatures up to 50°C, saline atmospheres in coastal regions or 316 stainless steel for food/pharmaceutical production areas.

Applications vary from air or water cooling for standard manufacturing processes to maintaining arctic fish at their natural habitat and cooling equestrian sea water treadmills in the deserts of Dubai!

Air conditioning – our water chillers can be supplied in various formats, from complete systems to condenser sets or evaporator packages. We offer various refrigerants and either scroll reciprocating or screw compressors.

Energy saving – with current concerns over rising energy costs and carbon emission levels, we have developed a special range of products designed to maximise energy efficiency. The units either use the ambient air to reduce the energy required to operate the system (free cooling) or they reclaim energy from the refrigeration system (heat recovery). We work closely alongside the Carbon Trust and a number of our clients have already benefited from their interest free Energy-Efficiency Loan scheme.

Our head office is based in Fareham, Hampshire and we have a national sales team and a network of fully trained service engineers who can offer clients a 24 hour, 365 day of the year call out facility for breakdown and repair.

We specialise in water chillers, free cooling, server cooling, server room cooling, data centre cooling, rack cooling, turbocor chillers, cooling towers, free air cooling, chiller service, adiabatic coolers, energy saving/efficient chillers, rear door cooling, chiller repair, air blast coolers, packaged water chillers, cooling system, heat recovery and much more.
