The retrofit of high efficiency EC motors and aerodynamically designed fans into air handling units, extract systems and IT cooling can reduce energy consumption by 30-70%.
Most new equipment will already incorporate EC fans, but there is an opportunity to increase the efficiency of older equipment by retrofitting the latest fan technology.
Many older CRAC units in data centre applications utilise belt drive forward curved fans
The replacement of these fans with the latest backward curved direct drive EC fans can reduce energy consumption by 30-70% and achieve a 2 year return on investment. While also removing the maintenance costs and debris associated with drive belts.
