2 At a glance GEA Bock compressors HG76e and HG88e The GEA Bock mexxflow valve plate system the flow-optimized combination of double ring fin valve plate and mexxflow cylinder head ensures a maximum of efficiency. Based on our current semi-hermetic product range, with its outstanding advantages and features, GEA Bock now presents you a new generation of the largest semi-hermetic compressors. The new GEA Bock compressor models HG76e and HG88e offer maximum efficiency and easy handling for chillers and performance-intensive refrigeration applications. The revised versions of the GEA Bock 6-cylinder and 8-cylinder compressors, have already established ten years ago, achieve new records in terms of efficiency due to the use of the GEA Bock mexxflow valve plate system. Special features GEA Bock achieves an advance in efficiency of the models HG76e and HG88e in comparison to its predecessors due to the use of the mexxflow valve system. With the mexxflow system pressure losses can be minimized thanks to a flow-optimized double ring fin construction of the valve plate in combination with a cylinder head, which is specially adapted to the valve plate. Thus, the efficiency of the compressors can be increased considerably. Disclaimer This brochure has been produced for you with the greatest of care.

7 Special features INT69 G Diagnose Unit Motor rotection Read facility via INTelligence diagnosis software With the INTelligence software, valuable information can be obtained on the status of the compressor and the system. The diagnosis function includes the plausibility checks of the logic sequences, all important operation and error values of the compressor and provides for its clear visualization. Crucial evaluation parameters can be configured individually. This allows for a quick analysis and an efficient system management. Advantages: --Simple operation --Immediate diagnosis and precise problem solving --Specially adaptable to the user s needs If required, data can be retrieved directly at each compressor via USB port. A Modbus interface is available for integration in a network. The data are sent periodically via the D-Modbus gateway and the Modbus-LAN gateway to a server and can be retrieved remotely by the INTelligence diagnosis software. The INTelligence diagnosis software can be downloaded for free at rotection Communication Software USB converter INTelligence (available for download) INT69 GTML Diagnose "on site" retrieval remote retrieval INTelligence server Internet D-Modbus Gateway Modbus-LAN Gateway Terminal box Customer Controller Further explanation can be found at In the event of inquiries please contact our Department for Application Technology, phone Gb Subject to change without notice 7
