Designed for water-cooled chiller applications and built with Turbocor technology, the TT700 compressors are oil-free, variable-speed, magnetic-bearing centrifugal compressors that provide full- and part-load energy efficiency.
The Carel HEOS Sistema is a high-efficiency solution for refrigerated cases. It features remote cases fitted with variable-speed BLDC compressors cooled by a water loop. Each case can adapt its operating pressure to the load conditions in real time, allowing the compressor to operate in the most energy-advantageous conditions.
Emerson Climate Technologies is presenting its Next Generation Copeland Scroll™ variable-speed compressor line, which the company says offers breakthrough efficiency, enhanced comfort, and proven reliability in residential and commercial HVAC applications.
Bitzer’s new Ecoline Varispeed compressor features an integrated suction-gas-cooled VFD that significantly lowers operating costs and ensures reliable and effective performance, even at high ambient temperatures.
While various aspects of HVACR technology seem to be lagging behind, compressors are keeping pace. And, of all the compressors being introduced, manufacturers are ensuring new offerings meet demands, operate intelligently, and, perhaps most importantly, perform efficiently.
Emerson Climate Technologies Inc. has announced the promotion of Brandy Powell to vice president of Variable Speed. In this role, Powell will be responsible for global strategy development, product line management, and new product development for Emerson’s variable speed compression technologies.
Turbocor began as a research and development company in 1993 in Australia before moving to Montreal in 1999. In 2004, Danfoss formed a 50-50 venture called Danfoss Turbocor. The company has since relocated its headquarters to Tallahassee, Fla.
The new Danfoss AK-PC 781 multifunctional rack controller simplifies set-up of energy-efficient capacity control of refrigeration compressors and condensers with modular hardware and flexible software that extends as system requirements grow or change, says the company.
