After years of chasing the attractive efficiency numbers offered by water-based evaporative systems, many data center providers are giving air-cooled chillers a second look.
It’s no secret that data centers require a lot of energy. The main driver of data center design engineers’ work is to provide energy-efficient, reliable, and cost-competitive HVAC systems.
Evapco’s newly-enhanced eco-Air™ Series of dry and adiabatic products provide great flexibility in a wide range of capacities, footprints, motor types and controls.
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).
STULZ has added chillers with a stepless capacity control (EC compressor) and an output from 20 to 100 kW to its portfolio. Chillers from the CyberCool Indoor series have been designed for indoor installation. The new version was specially engineered to precisely adapt to low or fluctuating heat loads. With a maximized temperature range from 4ºC to 18°C at the chilled water outlet, the CyberCool Indoor is suitable for a broad range of applications including data centers, medical technology, and process industries.
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.
Greenheck now offers low sound condenser fans as a standard offering on its Model RV and RVE pre-engineered packaged rooftop ventilation systems. Condenser fan noise levels can be a challenge with air-cooled packaged rooftop equipment installations.
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.
