With the new Grasso V reciprocating compressor series, GEA is heralding the start of a completely new era for the industrial refrigeration market. During the development of the GEA Grasso V series, GEA Grasso continually put itself in the position of the end user. Every component was assessed for the most important elements that contribute to a low Total Cost of Ownership like energy, maintenance and reliability with min. downtime. The result is not only the most effcient reciprocating compressor on the market but also a compressor with electronically controlled service intervals (extended as well as flexible) in order to reduce the Total Cost of Ownership without jeopardizing reliability. This new series replace the existing single stage series in a swept volume range from up to m³h. Compound (two stage) compressors will become available in 2013. Features of GEA Grasso V series Unique steel welded compressor housing No water cooling required Extended and flexible maintenance intervals Maintenance monitor for indication of upcoming service intervals Heavy duty axial roller bearing Counter pressure independent overflow valve Capacity control steps per cylinder Suitable for speed control Peek technology for high effciency and long valve life time Low noise leve Lowest total cost of ownership (TCO) Refrigerant: NH₃

Reciprocating compressors for CO2 freezing and NH3 heat pump applications. GEA Grasso 5HP series CO2 (Freezing) CO2 (Freezing) The 50 bar GEA Grasso 5HP compressor, developed for use in CO2 cascade freezing systems, is a well accepted and reliable appearance in the industrial refrigeration market. 4 single stage models from 3 up to 6 cylinders cover a wide range capacities. The extremely low volume flow in relation with the cooling capacity makes this series to a big performer. NH3 (Heat pump applications) A logic further development of the GEA Grasso 5HP series is the integration in NH3 heat pump systems. The 50 bar design makes it possible to condensate up to 82 °C and as a result of that produce high level of water temperatures. Heat pump systems are developing very quick in various segments of industry (Dairy, slaugther-houses etc.) and contribute in reducing waste heat as well as CO 2 emissions.

The GEA Grasso SH series comes in four sizes can cover swept volumes ranging from 231 to 372 m3h. The simple design is owed by the integration of the complete oil management system with only one oil connection and important package elements in the compressor. The screw compressors come equipped with connections for monitoring pressure and temperature, for position displays on the control screen, and for controlling the integrated solenoid valve assembly for combined Vi part load adjustment. The direct assignment of the solenoid valves to Vi and part load regulation and the connection of pressure and temperature sensors on the compressor ease assembly and service work on the package. The parallel slide system allows for Vi optimization and part load adaptation to take place simultaneously and independently of one another. It means that even in part load operations a low-loss work process is possible for the screw compressor. Technical features: Integration of package components Integration of oil management system Compact design Suitable for all standard DIN-flange motors Rotors fully bedded on roller bearings Capacity and Vi control by parallel slide system

The GEA Grasso MC series comes in four sizes with a swept volume ranging from 471 to 860 m3h. They have a simple and compact design between the compressor and package, where some unit components may come already integrated such as a suction side non-return valve, suction filter, an oil pump along with an oil and hydraulic system with the appropriate solenoid valve assemblies for Vi and part load adjustment. The control lines for the solenoid valve for Vi part load controls are connected directly to the compressor. Technical features: Integration of package components Integrated oil distribution system Compact design Roller bearings for thrust and radial load Stepless capacity and Vi control by parallel slide system

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. GEA Grasso SP1 series 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. Technical 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 SP1: Broad performance spectrum, universal application

Designed for high stage, booster or single stage operation GEA FES GL series 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 disccoupling 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 Advanced GEA GForceTM microprocessor control panel is standard with options for refrigeration system control
