We have finished installation of several Mitsubishi Heavy Industries AC units into the DC, latest model units with inverters. These units vary the compressor RPM depending upon required load and saves tremendously on energy consumption. Energy efficiency of these very large units are simply incredible.

At this very moment as i am writing this, the UPS units have as much overhead as our entire cooling system is using. Simply incredible! At this moment our PUE readings are back to what they were at during the winter, roughly 1.15 which includes the UPS unit overheads (all overhead is included in PUE reading, but usually the major contributor is cooling).

This makes our DC operations even greener than before as we have managed to make great strides in increasing power utilization efficiency in the past 2 years.
