The Danfoss Turbocor TG Series of centrifugal compressors delivers nominal capacities of 230 kW (65 Tons) up to 520kW (150 Tons) with all the benefits of oil-free operation. They operate with R1234ze refrigerant with a very low GWP which takes the environmental leadership while achieving the best energy performance levels.These variable speed oil-free compressors can be available for 380, 400, 460, and in some sizes 575 Volt applications and is intended for air- and water-cooled chiller systems. Unloading capability goes down to 65kW (18.5 Tons).HFO1234ze has a GWP (Global Warming Potential) value less than 1 and zero ODP (Ozone Depletion Potential).TG Series of oil-free compressors carries the CE PED mark.The new compressor models TG230, TG390, and TG520 are designed for standard temperature A/C applications
A new compressor model for medium temperature applications is also available.
Innovative Technology:Oil-free compressor operation is something the industry has worked decades to achieve. This oil-free design eliminates the efficiency losses due to the use of oil circulating in the compressor. It also suppresses the need for all the accessories for the oil management: oil heaters, oil pumps, oil separators, oil filters, etc., plus oil disposal.High Part-Load Efficiency:Danfoss Turbocor® oil-free compressor is a two-staged hermetic centrifugal compressor with a built-in variable frequency drive. It delivers high efficiency at full load and extraordinarily high efficiency at part-load conditions.Redefines Soft-Start:The TG Series of compressors redefines soft-start with only drawing 2 amps compared to 700-800 amps required by conventional fixed-speed compressors.Extremely Lightweight and Compact:TG310 compressor weighs only 132 kg, approximately 1/8th the weight of conventional compressors of equivalent 80 ton compressor while only requiring about half the space.
