| We can now offer evaporative cooling systems (CRECS) for data centres, UPS rooms, IT rooms and server rooms. Conventional Computer Room Air Conditioners (CRAC’s) are high users of electricity. An EcoCooling evaporative cooling system can significantly decrease these costs by over 90% giving potential pay backs of under a year and creating massive carbon savings |
| What has changed to make all this possible? |
| Modern IT is equipment is far more robust than older equipment. For example most manufactures specify a 10°C to 35°C operating temperature. Relative Humidity is not so critical now tape to tape and paper systems are no longer used. This has been exploited to a limited degree with the use of air economizers or free air cooling systems. Until now these still required a back-up of refrigeration system to accommodate the times of the year when ambient temperatures exceed 25°C. EcoCooling evaporative cooling systems (CRECS) remove the need for refrigeration completely by providing a constant flow of cooled air under 22°C – even during the warmest periods. |
| What can EcoCooling provide? |
EcoCooling have been working with data centres and server room equipment manufacturers to develop a modular system for retrofitting to existing facilities. Comprehensive process controls maintain compliant temperatures together with all of the connectivity required for the secure and safe operation of the total package.

| Computer Room Air Conditioners (CRACs) use a refrigeration system to cool air and pass it to the void under the raised floor. |
An EcoCooler takes external air and passes it to the void under the raised floor. Below 18°C ambient air is taken and mixed with air re-circulated from the hot aisle. Above 21°C the EcoCooler uses evaporative cooling to provide air which never exceeds 22°C. |
| How are the savings achieved? |
| An EcoCooling free air system provides a constant flow of attemperated air between 18°C and 22°C. No refrigeration is used – the air is cooled by evaporative cooling when ambient temperatures are high and is heated by recirculation of air from the server exhaust when the ambient temperature is low. No refrigeration is used as all of the cooling is achieved using evaporative cooling. This results in energy saving in excess of 90% compared with traditional Computer Room Air Conditioners (CRAC’s) |
