- Optimized rotor profile manufactured with the latest CBN (cubic boron nitrid) grinding technology for improved volumetric efficiency and lower power consumption
- 5:6 male to female lobe ratio for improved bearing load distribution, lower noise generation, and better bhp/ton performance
- Double-acting hydraulic capacity control, infinitely adjustable from 10% to 100% for premium part load operation
- GEA Omni™ control panel
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
The packages in the GEA Grasso SPduo series feature two parallel-mounted screw compressors each.
This solution is especially suited for part-load efficiency, flexible (part-load) operation and all applications where demands for machine availability and redundancy are most important.
Both screw compressors in the unit can be operated independently or at the same time in parallel to achieve top-level loads. You can equip one screw compressor with a variable speed drive motor and frequency converter to achieve part-loads down to 12 % without significant efficiency losses!
Highlights & Technical Features
- Optimized for highest efficiency in all load conditions Maximum machine availability, flexibility and redundancy – parallel or independent single compressor operation possible
- Easy operation and minimized footprint
- Parallel operation of 2 screw compressors possible
- Stepless capacity control via frequency inverter and/or slide system
- GEA Omni™ control panel with high-definition 15.6" touch screen
The GEA Grasso SP1 series of single-stage screw compressor packages has been designed to cover highly individual needs from medium to the largest cooling capacity range.
The series consists of 16 models from 638 kW to 9,311 kW (R717 | –10 / +35 °C | 3,600 rpm) refrigeration capacity. The GEA Grasso SP1 series is particularly attractive for its versatility, whether in the food industry or in a high-pressure version for CO2, in a heat pump installation or in an explosion-proof set-up for chemical application. Our customers can select from a multitude of options and customize the packages to all individual needs.
GEA Grasso SP1 horizontal variant
9 models from 638 kW to 2,667 kW (R717 | -10/+35°C | 3,600 rpm) are available in a horizontal oil separator design. This variant offers up to 20% less footprint than the vertical version but otherwise performs identically.
GEA Grasso SP1 HP variant
HP stands for high pressure, and this version is specifically designed for Ammonia heat pump and subcritical CO2 applications. The series is available with screw compressor sizes (frame size) from E to XA (R717 heat pumps to XD).
Highlights & Technical Features
- Widest range of single-stage screw compressor packages
- Individual and customized set-up for various applications and industries
- Horizontal design version for up to 20 % reduced footprint
- High pressure design version for ammonia heat pump applications, combined heating and cooling mode possible
- High pressure design version for subcritical CO2 applications, defrosting mode possible
- Stepless capacity control via frequency inverter and/or slide system
- GEA Omni™ control panel with high-definition 15.6" touch screen
