Danfoss Turbocor® oil-free
centrifugal technology
The Turbocor® family of compressors
delivers outstanding energy efficiency
in full- and part-load operation with
energy savings of more than 42%
compared to traditional compressors.
The outstanding integrated part-load
efficiency is the result of optimum
energy performance through the entire
operating range from 100% to ~20%.
The Danfoss Turbocor® compressor uses
an integrated variable frequency drive to
reduce compressor speed and maximize
energy cost savings as the condensing
temperature and/or heat load decreases.
The soft start module, which is standard
on every Danfoss Turbocor® compressor,
significantly reduces the in-rush current
at start up, provides advantages to line
power systems and reduces thermal
stress on the stator.
