Data centre cooling or technical cooling technology has to maintain environmental conditions suitable for information technology equipment to operate safely and efficiently. Achieving this goal requires removing the heat produced by the equipment continuously meaning reliability of the solution. A specific temperature is needed to be maintained at all times which can be problematic.
Technical cooling removes heat that is constantly generated by IT equipment, servers and business supporting equipment.
The servers need to be kept at a certain temperature to avoid overheating. Traditional air conditioning units are very expensive to install and even more costly to run if they are to be in use at all times. A huge amount of electricity is used to power a air conditioning unit.
Increasingly evaporative cooling units are being used to effectively cool data centres at a fraction of the price of the traditional air conditioning units.
Evaporative air cooling uses evaporation to cool the air. In an evaporative cooler, a pump circulates water from a reservoir around a cooling pad which becomes very wet. A fan draws in air from outside the unit and as the air passes through the pad it is cooled by evaporation.
Evaporative coolers only cool fresh air, unlike air conditioning units that use re-circulated stale air. Evaporative coolers only circulate 100% fresh air based on a completely natural process which cools the air using water NOT chemicals. The air is constantly replaced with fresh clean air which makes it a great option for people with allergies.


Save up to 10,000kg of carbon a year compared to a equivalent air conditioning system.
Up to 90% cheaper running costs than air conditioning.
Utilises a natural process which enhances the air.
Nasty odours are gone with no stale air circulating.
Doors and windows stay open while you benefit from a cooler atmosphere.
Evaporative cooling is often installed for comfort cooling reasons, to improve working conditions inside a manufacturing plant or warehouse. For application in a data centre evaporative cooling can be used to lower energy used by a server. Up to 80% more economical than conventional air conditioning systems. Seeley International’s evaporative cooling systems have delivered
proved cost reductions and operational returns throughout many industries.
If you would like information on how evaporative cooling units can be used in your data centre why not get in touch. Our experienced surveyors can visit your business free of charge and provide a detailed data centre cooling solution for you.
Evaporative cooling is a great cost effective and environmentally friendly cooling solution that is being adopted by more and more businesses over traditional air conditioning.

Data centres generate significant amounts of heat from servers, networking equipment and IT infrastructure. Effective cooling is essential to maintain performance, prevent overheating and protect critical systems from costly downtime.
Data centres can utilise a range of cooling technologies depending on their size, layout and operational requirements. Solutions may include evaporative cooling, mechanical ventilation and other specialist cooling systems designed to maintain stable operating temperatures.
Evaporative cooling uses the natural process of water evaporation to reduce air temperature. Fresh outside air passes through water-saturated cooling pads before being distributed into the building as cooled air.
Yes. Evaporative cooling can provide an energy-efficient and cost-effective solution for many data centre environments. It delivers a continuous supply of fresh air while helping to maintain suitable operating temperatures for IT equipment.
Yes. Energy-efficient cooling solutions can significantly reduce the electricity required to maintain safe operating temperatures. Many organisations choose evaporative cooling because of its low running costs compared to traditional air conditioning systems.
Cooling system failures can result in rapidly increasing temperatures, which may affect server performance and potentially lead to equipment shutdowns. Regular maintenance and monitoring help minimise these risks.
Yes. Routine servicing helps maintain efficiency, reliability and performance while identifying potential issues before they affect business-critical operations.
Yes. Cooling solutions can often be integrated into existing data centre environments. Following a site survey, we can recommend the most suitable approach based on your operational requirements and available space.
Yes. We provide installation, servicing, maintenance and repair services to help ensure cooling systems continue operating efficiently and reliably throughout the year.
Total Energy Services provides specialist cooling solutions across Dorset, Wiltshire, Hampshire and Somerset. As accredited installers of Seeley International cooling systems, we can design, install and maintain energy-efficient cooling solutions for data centres and other commercial environments.
