Internal evaporative coolers are easy to retro-fit
EcoCooling has developed a range of internal evaporative coolers for data centres that do not want to have plant and equipment on the outside of their building. They achieve a CoP (coefficient of performance) of 60 and a PUE (power usage effectiveness) of less than 1.2.
Existing data centres are likely to benefit most from ECT units because they can be readily retro-fitted to reduce energy consumption. A key point is that they do not require ductwork.
The ECT range is made in the UK. The design has been derived from a specification given by a major telecommunications server in the UK, which wanted the savings associated with evaporative cooing but needed internal units that were secure, easy to maintain and be installed quickly on a large scale.
A single metal box contains the evaporative cooling element, control system, supply fan and recirculation damper. Over 900 units have been installed in telephone exchanges throughout the UK.
