Design Features & Information
Pipework Design
Due to the unique oil free operation of the Turbocor compressor, the need for oil entrainment is eliminated. As pipe work
is not required to be sized for oil return it is possible to size pipe work for minimal pressure losses through the system
with maximum cooling capacity and optimised unit EER.
