In line with the requirement for sustainability, EcoCooling were asked to design a low energy, low carbon cooling system for the new NHS call centre at Bow – which is to become the HQ for the 2012 Olympics.

Three EcoCooling CRECS (Computer Room Evaporative coolers) have been installed to provide over 80KW of cooling. This includes the required N+1 redundancy to achieve ASHRAE standards. No refrigeration based equipment will be used.


The EcoCooling CREC is designed to give a saturation efficiency of 90%. This results in a maximum air supply temperature of 23C. This applies during extreme weather conditions such as those experienced in 2003 when the ambient temperature approached 35C.

A patented attemperation system maintains a constant temperature supply to the IT equipment. The hot air is mixed with ambient or evaporatively cooled air, using a single damper. When the external temperature rises over a set point the evaporative cooling is enabled to ensure either the typical target air supply temperature of 21C is achieved or slightly over during the very hottest periods. A standard EcoCooler CREC module will supply ~3 cubic meters per second which can support over 35kW of IT load.
