2 In touch with our customers GEA Refrigeration Technologies: Your partner for low temperatures GEA Refrigeration Technologies, part of the internationally active GEA Group, is a synonym for industrial refrigeration technology. Since the end of the 9th century, it has been our business to cool processes and products, and to control the temperature of goods in transport. You will find our solutions in the food and beverage sector; in the petrochemical, chemical, and pharmaceutical industries; on fishing ships; in natural gas liquefaction; in infrastructure facilities; and in ice factories. We are also at the top with know-how when it comes to refrigeration at leisure facilities. After all, we have been excited about refrigeration for decades now. As a result, our staff enthusiastically goes about its development and production projects to include preventive and remedial maintenance of your refrigeration systems. This enthusiasm is highly apparent in the daily work of all companies in our Segment. Whether it s complete systems or individual valves: we have the experience in every section of our company to optimally design, manufacture, and install refrigeration systems. And to take full advantage of this experience, we not only carry out development in our own company: we also manufacture, assemble, and test the core components. A chain is, after all, only as strong as its weakest link: and this also applies equally well to refrigeration technology, cooling processes, and cooling chains. This makes it all the more important that you have a partner in GEA Refrigeration Technologies that has learned to master refrigeration from A to Z. And all of this since 896, when Willem Grasso founded his refrigeration division. From this history of GEA Refrigeration Technologies, you will profit in the form of technical expertise and top sector know-how. But we all live in the present and think about the future. We ponder a future in which more and more processes need energy around the world, and fewer natural resources are available. As a result, we have taken it as our goal to create solutions that are not only long-life and cost-effective, but also energy-saving and environment-protecting. We feel obligated to sustainability in many respects. Our objective is to produce longlife and material-saving products over the long run as well as products that use environmentally benign refrigerants. And we aim to produce efficiently. But our responsibility does not end at the factory gate. As a result, we take great pains to ensure that our systems are energyefficient and that they protect the climate. With GEA Refrigeration Technologies, you can also count on optimal economy: saving energy indeed means reducing money spent for energy. At the same time, you protect the environment. Thanks to our refrigeration technology, your processes will run more economically and more ecologically. To maintain our standard of living and to assure quality of life for future generations as well. Our claim of combining economy with saving natural resources is reflected in all components of our company, such as the following: compressors, chillers, heat pumps, ice machines, fittings and valves, control systems, and many, many more. You can find proof of the above throughout the world. Our international corporate network and above all our reference projects are spread all over the globe.

4 GEA Bock - More than a compressor Over 75 years ago, when the refrigeration and air-conditioning industry was still in its infancy, our company's founder, Wilhelm Bock, had a vision: he wanted to build first-class and reliable refrigeration machines. In the following decades Bock developed into one of the world's leading manufacturers of refrigeration and airconditioning compressors. Today, GEA Bock offers as part of GEA Refrigeration Technologies the right compressor for all fields of commercial-, industrial-, rail-, bus- and transport refrigeration. That GEA Bock places the highest demands on compressors for energy efficiency shows our EFC system. For many years we offer with the EFC system a solution to reduce the energy consumption by 5 %. In this brochure we present you our current program of singlestage and two-stage semi-hermetic Bock compressors. Be inspired. By our new products, our established product series and the entire passion that goes into each of our products. 4

15 Semi-hermetic Bock Compressors Forward looking compressor models HA System Hermetic Air-cooled Semi-hermetic air-cooled compressors for deep-freezing (R/R4A) A semi-hermetic compressor with the advantages of an open type. Available for all and 4 cylinder versions. Increasingly high specifications are being set for all suction gascooled semi-hermetic compressors for deep-freezing applications. Compressors rapidly reach their temperature limits due to the rise in temperature of the suction gas caused by the drive motor. The refrigeration capacity also diminishes. But not in Bock HA compressors. The unique Bock HA principle prevents this. The drive motor is aircooled and compressor suction is direct. The suction gas is not heated by the motor, but is fed directly to the compressor without being diverted through the motor. The motor is cooled by a compact integrated ventilation unit. Its precise airflow cools not only the motor but also the compressor and especially the cylinder heads. 3 Suction gas is fed directly into the compressor The motor is cooled by an integrated ventilation unit Cool air is directed over the motor through an air duct hood This results in a reduced discharge gas temperature and therefore an extended range of applications combined with improved capacity (deepfreezing - e.g. R, R4A). In addition, the compressor is separate from the motor, which is a particular advantage in the event of a motor burnout

Restrictions to the operating limits may occur when using the Bock EFC (Electronic Frequency Control). Further explanation see separate brochure "Bock semi-hermetic compressors - Electronic Controls". erformance data ASERCOM is the Association of European Refrigeration Compressors and Controls Manufacturers. Information about the Association and the constantly updated overview of certified Bock compressors can be found at and The performance data for R34a are based on ISO-DIS 99 (DIN 898) with a Hz power supply frequency. This signifies: 5 C suction gas temperature without liquid subcooling. For luscom compressors and HGX8/470-4 operating at Hz already comply with EN 900. This signifies 0 C suction gas temperature without liquid subcooling. This results in significant differences compared to specifications with liquid undercooling and/or suction-gas temperatures. A comprehensive modification to 0 C suction gas temperature will follow at a later date. Conversion factor for 60 Hz =, erformance data for other operating points, see GEA Bock software. 0

26 Single-stage Bock Compressors Notes R4A/R7 Notes Operating limits ASERCOM certified performance data Compressor operation is possible within the limits shown on the application diagrams. lease note the coloured areas. Compressor application limits should not be chosen for design purposes or continuous operation. For compressors with this label, the performance data are certified according to the strict requirements of ASERCOM. Restrictions to the operating limits may occur when using the Bock EFC (Electronic Frequency Control). Further explanation see separate brochure "Bock semi-hermetic compressors - Electronic Controls". erformance data ASERCOM is the Association of European Refrigeration Compressors and Controls Manufacturers. Information about the Association and the constantly updated overview of certified Bock compressors can be found at and The performance data for R4A/R7 are based on European Standard EN 900 with a Hz power supply frequency. This signifies: 0 C suction gas temperature without liquid subcooling. This leads to significant differences compared to systems with liquid subcooling and/or other suction gas temperatures. erformance data were compiled for R4A and R7. The base values are the data for R4A. Conversion factor for 60 Hz =, erformance data for other operating points, see GEA Bock software. 6
