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.
Carrier’s newly expanded AquaEdge 19XR centrifugal chiller line is now commercially available up to 3,000 tons. The line, which was introduced in early 2014 to serve large buildings and process applications, is now available from 800 to 3,000 tons.
Continental Fan has introduced the new DXG & DXP AC Motorized Axials. The coupling of the motor and impeller minimizes space requirements and provides for vibration free operation. Both motor and impeller are located directly in the air stream, providing excellent heat dissipation and efficient motor cooling, according to the company.
Greenheck has expanded its line of mixed flow inline fans with the addition of Model EQB. According to Greenheck, the fan combines the best properties of centrifugal and vane axial fans while providing higher efficiency and lower sound levels. Model EQB’s octagonal housing is manufactured of formed galvanized steel panels coupled with a heavy-gauge steel drive frame for and durability.
Wilo USA has introduced its new Stainless Steel Closed Coupled (BLZ) centrifugal pumps. The pumps are base-mounted featuring end suction-centerline discharge design, compact design, a foot-mounted volute, and permanently lubricated ball bearings. BLZ series pumps, which are suitable and approved for pumping clean, potable water, are easy to install, operate, and service, according to Wilo reps.
Engineered Systems magazine’s September 2019 issue questions the need for multiple building codes that cover the same subjects, examines the dos and don’ts of power systems for critical facilities, offers tips on how to select the proper centrifugal pump circuit flow controls, and much more.
