Danfoss’ Turbocor VTT Series of oil-free, variable speed, magnetic bearing centrifugal compressor was selected as the winner of the 2015 AHR Expo Product of the Year during the Innovation Award ceremonies Jan. 27 at the world’s largest HVACR event in Chicago.
The new Danfoss VTT (Variable Twin Turbo) series compressor was chosen from among the top Innovation Award winners in 10 industry-related categories. Intended for commercial air conditioning or process cooling applications that require a high efficiency solution, the innovative compressors qualified to compete for the top award by taking top honors in the “Green Building” category.
According to Danfoss, the Turbocor VTT series of compressors takes all the benefits of magnetic bearing technology up into larger capacity ranges, where the current Turbocor TT series leaves off. VTT compressors introduce innovative IntraFlow technology that enables chiller systems up to 1,000 Tons or more to provide improved reliability and increased efficiency with the largest stable operating range of any centrifugal compressor. The VTT is a high-efficiency solution for commercial air-conditioning or process cooling applications and recently won the prestigious 2015 AHR Expo Innovation Award in the Green Building category. This is the third time that Danfoss Turbocor Compressors have been recognized with an AHR Innovation Award.
Turbocor VTT series The company also received an Honorable Mention in the cooling category for its ETS Colibri electronic expansion valve. Together, this marks the 17th and 18th time Danfoss has been recognized in the AHR Expo Innovation Awards program over the course of 12 years.
Danfoss ETS Colibri electronic expansion valves enable precise evaporator flow control for increased energy efficiency and reliable compressor operation – ideal for variable speed air-conditioning and lower-GWP refrigerant systems. Featuring a hermetically-sealed, smaller, four-times-lighter design that means less design complexity with fewer parts and leak points, and 3-to-6-second fully-open-to-close functionality, ETS Colibri offers simple programming and flexible installation, helps reduce refrigerant loss, and prevents significant liquid from reaching the compressor – thus, improving reliability and reducing service calls.
