As the demand for electrical power increases, distribution systems are expanded to accommodate the increased demand. Stiffened transmission systems, increased substation capacity, and added on-site and distributed generation all contribute to increases in available fault currents.
The new Mega-Stack option for Greenheck’s Model FJI FumeJet® fume exhaust fan offers extended discharge from 10-15 feet in overall stack discharge height, making it ideal for low flow applications requiring higher plume rise.
Wilo USA announced an extended range of models for the Wilo-Stratos GIGA line of centrifugal pumps to include 3- and 4-in. models, bringing the total offering of the Wilo-Stratos GIGA line to 28 models.
Danfoss has introduced the new Danfoss Turbocor® TT700 compressor — expanding to a larger capacity its existing range of Turbocor® TT series compressors. Designed for water-cooled chiller applications, the new TT700 compressors are oil-free, variable-speed, magnetic bearing centrifugal compressors that provide full- and part-load energy efficiency. The company claims the compressors also feature a small footprint, are light weight, and offer low vibration, very low sound, intelligent controls, and soft starting characteristics.
