While there are still a significant number of single-speed motors still in operation, many OEMs are making a concerted move toward variable-speed equipment in order to meet a growing demand for higher efficiency. To help OEMs meet their goals, and to meet increasingly stringent motor efficiency regulations from the U.S. Department of Energy (DOE), motor and drive manufacturers have introduced their smartest, most efficient products yet.
Eaton’s B-Line Series KwikWire Hanging System is a flexible replacement for jack chain or all threaded rod (ATR) for hanging items such as HVAC duct, a wire basket cable tray, lightweight air-handling equipment, and more.
As the DOE mandates minimum efficiency performance and the EPA delists ozone-depleting refrigerants, manufacturers are being tapped to create speed-controlled compressors that run on an array of natural refrigerants.
The second-generation Copeland Scroll variable-speed ZPV2 compressor features intermediate discharge valves to boost efficiency, optimized scroll elements for variable-speed performance, a positive displacement oil pump for enhanced reliability in low-speed operation, and brushless permanent magnet (BPM) motor technology.
