Instant Payback continued The front desk and lobby of Quilogy’s corporate headquarters in Saint Charles, MO “The hot air is then exhausted out the back of each rack and allowed to rise to the ceiling where it is returned to the air handler for cooling. The high ceilings in the room make the Trane cooling system even more effective. These ceilings are one of the benefits of being in an old building. Thus we have both a hot/cold horizontal aisle arrangement, as well as hot/cold vertical planes.” In late 2005, Quilogy moved its data center from a smaller room of the building to a new and significantly larger area. At the same time, the capacity of the data center was expanded to three times that of the previous one in terms of power capacity, redundant cooling capacity, and the floor space to add more racks in the future. Quilogy’s previous backup generator was a 25-kilowatt Generac Guardian natural gas-model that had been in service since 2000, which had performed well during outages. The new data center required a new larger unit. Both the facility design firm and a general contractor recommended diesel generators from other manufacturers, but Groh wanted to consider other options. After learning about the Generac QT Series, he was convinced that it was a superior solution, combining the numerous advantages of natural gas (no refueling, storage, spillage, spoilage, or odor) with a lower capital cost. “Our experience with the gaseous-fueled Guardian unit was favorable, so there was no reason to make a change,” Groh says. “By selecting the QT model, we easily saved more than $10,000 when compared to the diesel alternatives. It was an easy decision.” The Generac QT 130 kilowatt model has capacity to satisfy Quilogy’s evolving power requirements. The QT 130 can handle the upgraded 400-A, 208-V three phase electrical requirements. With Quilogy located in an historical area with shops and offices nearby, sound was another important factor in the decision to purchase the QT model. Because of its sound-attenuated enclosure and advanced airflow design, the generator is among the quietest in its class when operating under load. During weekly exercise, the Quiet-Test feature operates the gen set at a slower speed, making it even quieter. “Our generator is so quiet during the self-test that a person can not tell that it’s running without standing directly next to the unit,” says Mike Howells. Generac offers its QT products through several distribution channels. Quilogy’s purchase was made through Chicago-area distributor A.P. Electric.
