Oil-Free Turbocor® TG490 Compressor and CO2 Adaptive Liquid Management (CALM) Solution – Danfoss
ORLANDO, Fla. — The new Danfoss Turbocor® TG490 is the an oil-free, variable-speed, magnetic bearing centrifugal compressor qualified for the use of R-515B, which 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 1. 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 exceptional 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.
