Danfoss, the world’s leading manufacturer of oil-free compressor technology, has expanded the oil free compressor portfolio with the introduction of the Danfoss Turbocor® TG490 and the VTX1600 models. 

The new Danfoss Turbocor® TG490 is the world’s first oil-free, variable speed, magnetic bearing centrifugal compressor qualified for the use of R-515B. R-515B has an AR5 GWP of 299 and an ASHRAE A1 safety classification for lower toxicity and no flame propagation. As an extension of the existing Danfoss Turbocor® TG series of compressors, it also is qualified to use HFO-1234ze, an environmentally-friendly refrigerant with a GWP less than one. With this new refrigerant option, Danfoss expands the use of low-GWP refrigerants that will help to minimize harmful emissions and meet evolving regulations. 

The new Danfoss Turbocor® VTX1600 compressor brings the benefits of oil-free, magnetic bearing technology to larger capacity chillers. The 450 ton / 1,600 kW nominal capacity rating allows for a multiple compressor configuration up to 3,600 tons / 12,660 kW or larger. The VTX1600 compressor, optimized for water-cooled chiller applications, uses an advanced aero design that gives industry leading full-load efficiency with no performance degradation over the life of the compressor. Combined with the advanced aerodynamic design, the VTX1600 provides outstanding unloading capability even at constant entering condenser operating conditions. 

“The new Danfoss Turbocor® TG490 compressor, using low-GWP R515B with an ASHRAE A1 safety classification, delivers a market need for high efficiency chillers for areas that do not permit the use of A2L refrigerants—enabling compliance with both refrigerant regulations and safety codes,” said Ricardo Schneider, president and CEO, Danfoss Turbocor Compressors. “In addition, the VTX1600 expands the capacity range of oil free compressor technology up to 450 tons / 1,600 kW allowing for larger capacity oil-free chiller configurations up to 3,600 tons / 12,660 kW or bigger.” 

Additionally, the new Danfoss Turbocor® TG490 and VTX1600 models, like all Danfoss Turbocor® compressors, feature oil-free, magnetic bearing compressor technology that offers the benefits of industry-leading efficiency, reduced maintenance and simplified design through the elimination of the traditional oil management system. Oil-free, magnetic bearing technology also incurs no performance degradation or mechanical wear over the life of the compressor. 

The Danfoss Turbocor® TG490 was selected by a panel of third-party ASHRAE member judges to receive a prestigious Innovation Award during the 2020 AHR Expo in Orlando, Florida.
