Danfoss Turbocor Compressors Introduces IntraFlow Technology on New VTT Compressor Series

VTT Series oil-free centrifugal compressors with up to 350 Tons cooling capacity introduced at 2014 AHR Expo

Tallahassee, Fla. — At the 2014 AHR Expo in New York City, held January 21-23, Danfoss Turbocor Compressors Inc. (DTC), the pioneer and world leader of variable speed, oil-free compressors for the HVAC industry, 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 460Volts as well as 575Volts.  These models are intended for water-cooled or evaporative cooled chiller applications and will carry the ETL and CE PED mark.

Based on proven TT series compressor technology, the VTT models are oil-free, variable-speed, magnetic bearing centrifugal compressors.  The VTT series of compressors is the first to introduce IntraFlow™TM technology, an innovative and patent pending technology for improving compressor efficiency and providing an extended stable operating range while simplifying capacity control.

The new drive technology, which will be exclusive to the VTT series of compressors, is the result of integrated RD efforts blending Danfoss’ extensive expertise and capabilities in high efficiency compressors and variable frequency drives for the HVAC industry.  The VTT drive will have the superior reliability and performance that has come to be expected from Danfoss in a small frame size made achievable only with refrigerant controlled heat removal.

The VTT compressors will also include newly developed control electronics capable of communicating via USB, Ethernet, and wireless.  Other new features include USB drive data recording, shaft speed detection, motor & drive cooling and condensation protection.  These compressors will also have the capability to download firmware and configuration updates remotely without requiring any hardware exchanges.

The 350 Ton compressor will be the first from the VTT series to be available and deliveries will start in the third quarter of 2014.
