Best efficiency with all loads

GEA Grasso SPduo

GEA Grasso SPduo is a design concept featuring two screw compressor drivelines in parallel arrangement. The individual operation of each compressor makes the SPduo package provides top efficiencies in all loads plus availability in one single, compact unit.

GEA Grasso SPduo

GEA Grasso SPduo units are particularly suited for part/load efficiency, flexible (part-load) operation and all applications where demands for machine availability and redundancy combined in a single, compact unit are most important.

Both screw compressors (identically sized) can be operated independently from each other or simultaneously at full load to achieve top-level capacities. Furnish one or both drivelines with a variable speed drive motor to achieve part-loads down to 12 % by speed control without significant efficiency losses.

GEA Grasso SPduo units are based on a common base frame, oil circuit and common control and thus easier to install, operate and maintain while in addition requiring less space than two separate single-stage packages.

The series provides 15 models covering a wide cooling capacity range from 344 to 3,982 kW (R717 | -10/+35°C | 3,600 rpm). The first 6 models can be equipped with a third parallel compressor driveline (customized option on special request).

Highlights & Technical Features

  • Individual operation and regulation of the two separate compressor drivelines
  • Optimized for highest efficiency in all load conditions
  • Machine availability and redundancy
  • One piece – easy installation, operation and maintenance, minimized footprint
  • Variable speed drive motors (optional) with speed range 1,000 - 4,500 rpm (R to T models 1,500 - 4,500 rpm, P and V to Y models 1,500 - 3,600 rpm)
  • Stepless capacity control via frequency inverter and/or slide system
  • GEA Omni™ control panel with high-definition 15.6" touch screen
