Danfoss VTT Has Capacities from 200 to 350-tons
At the 2014 AHR Expo in New York City, held January 21-23, Danfoss Turbocor Compressors Inc. (DTC), introduced the VTT line of compressors. VTT (Variable Twin Turbo) is the model group name of the latest compressor innovation from Danfoss Turbocor Compressors. The VTT series of compressors will be available with nominal capacity ranges from 200 to 350 tons for voltage applications between 380 to 460 volts as well as 575 volts. These models are intended for water-cooled or evaporative cooled chiller applications and will carry theElectrical Testing Labs (ETL) and CE PED (Pressure Equipment Directive) marks. Danfoss sources report the VTT models are oil-free, variable-speed, magnetic bearing centrifugal compressors. The VTT series of compressors is the first to introduce IntraFlowTM technology, an innovative and patent pending technology for improving compressor efficiency and providing an extended stable operating range while simplifying capacity control. turbocor.com
