MECHANICAL CAPACITY CONTROL
Powerstream’s compact semi-hermetic screw compressors are distinguished by a further improvement in energy efficiency under full and part load conditions. As a result, these compressors exceed the international efficiency standard of compact screws with respect to the seasonally weighted energy requirements to an even higher degree than before. This results in particularly high ESEER/IPLV and SCOP values.
The cooling capacity of the compressor is controlled by a slider, which allows an adaptation of the compressor displacement to the power requirement by shifting the start of the compression process through the axial movements of the control slider. The slider, starting from the full load position (100%), can be infinitely adjusted to a nominal of 25%.
