Basic market needs for current data center designs are addressed through SEMCO’s simple approach. This system, designed specifically for data centers, incorporates few components with an easy to maintain and logical hydronic coil system achieving a typical annual Power Usage Efficiency (PUE) of 1.122 (based on Washington DC area conditions).
The diagram above shows the basic piping arrangement between the two airstreams. Designed to handle a range of temperature differentials, this high-efficiency system not only rejects heat for the data center, but also starts to economize at an outdoor ambient temperature within 10 degrees of the desired process side leaving air temperature! This is 20-30 degrees warmer (sooner) than other air-to-air competitive options.
