Most engineers focus on improving energy efficiency to reduce energy consumption.

In April of 2011, the University of Utah broke ground on a renovation to consolidate multiple production centers into a central multi-tier data center in support of their diverse program mix, which includes the university’s Center for High-Performance Computing (CHPC).

Quantech has expanded its line of QTC4 Air-Cooled Variable-Speed-Drive Screw Chillers to a total of 21 models ranging from 150 to 360 tons. With the expanded line, Quantech officials said many models are in-stock ready to ship within three to five days to enable immediate chiller replacement.

Quantech™ has expanded its line of QTC3 Air-Cooled Scroll Chillers up to 200 tons. The company says its new QTC3205 offers a more cost competitive solution to 200-ton opportunities without sacrificing size, quality, and efficiency.

RAE Coils announced that it is manufacturing replacement and OEM evaporative condensing tube bundles. The company claims the tube bundles are a critical component of the highly-efficient condensing units originally manufactured by Mammoth’s Ultraline and Penthouse brands. Also, when compared with air cooled technology, officials said the product can result in a reduction of up to 35% in annual operating costs.

Armstrong Fluid Technology has introduced a new chiller plant automation system targeted at optimizing the performance of air-cooled chiller plants. The company says the IPC 9511 streamlines plant operations and can lower operating costs. Facility managers and engineers can benefit from this fully field-configurable solution with automation features for constant speed and variable speed configurations.

Trane has introduced the newest addition to its air-cooled chiller product portfolio, the Trane Stealth™ air-cooled chiller. Available in the 150- to 300-ton capacity range, Stealth air-cooled chillers deliver a combination of part-load and full-load efficiencies along with extremely low sound levels. At the core of the Stealth chiller’s performance is AdaptiSpeed™ technology – the integration of a direct-drive, specific-speed screw compressor, permanent-magnet motors, and third-generation Trane Adaptive Frequency™ Drives.
