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.
International Environmental Corporation (IEC) introduced its new Horizontal and Vertical (HDY/VDY) Direct Drive Blower Coil Series. Accommodating a variety of applications, these models are equipped with a direct-drive EC motor, eliminating belt-drive slips and other concerns associated with belt-drive systems. The company says the new line offers an alternative that is more reliable and efficient, resulting in increased energy savings, an extended motor life, easier installation, and less maintenance.
