(SFC)
Kaesers oil-free screw compressors are available with
integrated Sigma Frequency Control (SFC) to provide superior
part load efficiency and steady pressure in applications with
varying air demands. Standard features include EMI filters and
line reactors for extra electrical system protection.

Energy-saving drying
An integrated design, together with the generously-dimensioned
aluminum block heat exchanger, keeps pressure loss less than
1.5 psi. The energy-saving scroll refrigeration compressor helps
achieve compressed air energy savings.
Excellent accessibility
All refrigerated dryer components are easily accessible via the
service door on the front of the unit, making dryer service and
maintenance work a breeze.

Heat recovery
Air-cooled compressors
Recovering warm compressor exhaust air is an innovative way
to seize savings potential. Kaeser has the expertise to help you
with everything you need to know and will be with you every
step of the way.
Water-cooled compressors
Using the compact heat recovery module integrated directly into
the compressor, generating hot water for production or auxiliary
heating purposes couldnt be simpler. Cost and space-intensive
external infrastructure is not necessary with Kaesers solutions
and the amortization period of the heat recovery module is
usually less than a year (see sample calculation below).
