Specifying a chiller for a given application requires understanding the process to be cooled and its temperature stability demands. Many processes can be adequately supported with ±3°F temperature precision.
Aggreko introduced a 230-ton air-cooled screw chiller into its fleet. Powered by variable-speed technology, the unit offers a range of process cooling capacity from 5 to 70°F and delivers increased fuel savings.
Authenticated lubricants guaranteed to meet the specifications for particular chillers and mechanical cooling applications were developed to protect customers from the risks of counterfeit oils, says Johnson Controls.
As water resources become increasingly stressed by drought and intensifying demand from competing uses, industries that use significant quantities of water will face greater pressure to
adopt water-efficiency strategies that can decrease fresh-water withdrawals. One approach that facilities can adopt to reduce their draw from these supplies — thus reducing stress on drinking
water reserves — is to use alternative makeup water sources.
Most people think of coil cleaning as a building or facility prepares to turn on the air-conditioners for another season. Admittedly, spring is a perfect time to put such cleaning and maintenance at the top of the to-do list.
Chiller with variable-speed compressor operates effectively between 10 and 100 percent of its rated capacity. The design applies variable-speed green compressor technology from the HVAC industry to produce energy savings over traditional hot gas bypass regulation.
Many applications require water for cooling. Rotary evaporators, microscopes and spectrophotometers found in the laboratory can require cooling water. Industrial-scale applications such as semiconductor, additive manufacturing and extraction processes also typically require water for cooling.
Opteon XP10 (R-513A), a low global warming potential (GWP) refrigerant from Chemours Co., has been selected by Dunham-Bush for use in its DCLCG series of high efficiency direct-driven VFD water-cooled centrifugal chillers for the Asia Pacific market.
