GEA Grasso Screw Compressor Packages

Southern Sales & Services offer GEA Grasso screw compressor packages whether it’s in the food industry, chemical industry, in offices or in shipping, they all need refrigeration. GEA Refrigeration Technologies has the optimal cooling and air conditioning solutions for your individual requirements. We place particular value on energy efficiency, reliability, cost effectiveness and sustainability.

The high reliability and long life of our GEA FES and GEA Grasso screw compressor packages is the result of fifty years’ experience in compressor technology. Everything began with a series of single stage packages. Today we produce four models with more than 50 different package sizes. They are suitable for the operation with natural and all other common refrigerants. Next to our standard models we also produce tailor-made solutions for customer specific needs.

  • GLX Series
  • GMX Series
  • M Series

Available GEA XSeries Options:

  • Liquid injection oil cooling provides reduced field piping, precise discharge temperature
    control and low discharge pressure operation for lower operating costs
  • External oil cooling with OMC temperature control valve:  Thermosyphon, Water-cooled, Glycol-cooled
  • Dual oil filters
  • Variable speed operation: Variable frequency drive with or without solid state backup
  • Motor bearing electrical discharge machining prevention
  • Microfiber drive end shaft grounding ring
  • Insulated non-drive end bearing
  • Compressor and motor vibration monitoring system
  • System controls

GEA Grasso – GMX Series

The GMX series is available in 4 models, 50 – 300 HP, utilizing various refrigerants including R-717, R-22, R-507, R-134A, R-744 and others.

Package features:

  • Multi-stage oil separator design guarantees low oil loss
  • Three-way thermostatic oil temperature control
  • valve standard with oil cooler options
  • High performance, all steel, flexible disc coupling with factory assembled center member for quick installation and removal

  • Shimless motor mounts provide fast, easy, and accurate motor alignment checks
  • GEA Omni™ control panel

GEA Grasso – M Series

GEA Grasso M series package is the new range of GEA screw compressor packages. Thanks to their new engineering design and the reduced complexity of their components, these new models combine reliability and ease of servicing with even greater efficiency. These characteristics – with the resulting significant reduction of total costs over their entire life cycle – have exceptionally positive effects on their cost effectiveness.

Package features:

  • New screw compressor design for optimal efficiency
  • New GEA Omni™ control panel with high-definition 15.6″ touch screen
  • Speed range of 1000 – 4500 rpm
  • Best in class warranty with very low service intervals
  • Option of high-speed motor for increased part-load efficiency
  • Stepless capacity control via frequency inverter and/or slide system
  • Compact dimensions

GEA – GS Series

The GS series is available in 4 models, 25 – 150 HP, utilizing various refrigerants including R-717, R-22, R-507, R-134A, R-744 and others.

Package features:

  • Multi-stage oil separator design guarantees low oil loss
  • Partial-flow, full-time oil pump
  • Three-way thermostatic oil temperature control valve standard with oil cooler options
  • Patented low pressure drop suction strainer
  • High performance, all steel, multiple disc coupling with factory assembled center member for quick installation and removal
  • Unique keyless frictional coupling hub on the compressor end provides an easily adjustable and releasable mechanical shrink fit
  • Uses industry standard size motors with oversized junction box for easier connection
  • Shimless motor mounts facilitate fast, easy, and accurate motor alignment checks
  • GEA Omni™ control panel
  • SP1 Series
  • SP2 Series
  • SPDuo Series

GEA Grasso – SP1 Series

The single-stage screw packages of the GEA Grasso SP1 series include 22 package sizes with a capacity range of 130 to 5,700 kW. The smaller size models feature a larger integration level of components and thus a smaller amount of connecting elements. The packages in the bigger capacity area are fitted onto a separate base frame, which ensures running with less noise and vibration.

Package Features:

  • Stepless capacity control by frequency inverter and capacity slide
  • Robust base frame for long motor bearing lifetime
  • Low positioned gravity center for a low vibration level
  • Oil separator with variable sizes and low oil charge to achieve an oil carry over of less than 5 ppm
  • Efficient oil cooler with optional waste heat recovery
  • System control GEA Grasso GSC a reliable operation

GEA Grasso – SP2 Series

The GEA Grasso SP2 series with 18 package sizes covers a capacity range from 135 to 2,100 kW. The two-stage screw packages are designed for the production of higher pressure conditions. They consist of two serially mounted compressors for the low- and highpressure side. Depending on the required cooling capacity on a medium pressure level, various high pressure compressors can be combined with the basic unit. This leads to a considerable increase in the cooling capacity.

Package Features:

  • Common base frame for low and high pressure compressor reduces needed space in engine room
  • Flexible combination of low- and high pressure compressors enhances the adaption to any side-loads at medium pressure level
  • Optimum energetic operation with intercooling
  • Relieved starting of the low- and high-pressure compressor reduces motor currents and starting torques
  • Independant operation of the high-pressure compressor optimizes the low-load operation and stand-by operation

GEA Grasso – SPDuo Series

The GEA Grasso SPduo series covers a capacity range from 250 to 3,200 kW. The screw packages stand out for their compact design with two parallel mounted compressors on a common base frame and a single oil circulation. As a result, they are distinguished by a very good part-load efficiency and are ideally suited for short-term top-level loads.

Package Features:

  • Based on high quality GEA Grasso screw package components
  • Best COP in all load conditions
  • Increased machine availability
  • Parallel or independent compressor operation
  • Reduced investment costs
  • Designed for NH3 and all other common refrigerants
