Grasso screw compressor LT series 

LT series screw compressors have all the latest features of Grasso screw compressor technology. The tandem slide system in conjunction with the compressor control device offers new possibilities for combined Vi part load adjustment.


LT series screw compressors are installed in the large series screw package in the traditional manner. The optimal Vi-values for compression in full and part load conditions are calculated and hydraulically adjusted by the compressor control device.
