Experience the benefits of oil-free technology in high lift applications

The world’s first oil free compressor optimized for high lift applications.

The Danfoss Turbocor® TTH/TGH oil-free centrifugal compressor is specifically designed for high lift applications such as air-cooled chillers in hot ambient climates, heat recovery, heat pumps or thermal storage.  The TTH/ TGH compressor provides a high-performance alternative to the traditional oiled screw compressor that is more efficient, quieter and with a smaller physical footprint.

In addition, oil free technology has no performance degradation over the life of the compressor unlike traditional oiled screw compressors which can incur performance degradation due to excess oil and mechanical wear over time.

As part of the Danfoss long-term refrigerant strategy, the TTH/TGH compressor is available with low GWP refrigerant options. The TTH model utilizes R134a and is compatible with non-flammable R513A while the TGH model uses ultra-low GWP HFO-1234ze.
