Bock Semi-hermetic Compressors Electronic Controls Intelligent Compressor Solutions engineering for a better world GEA Refrigeration Technologies

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...

° Bock Compressors Production Program Semi-hermetic compressors HG (HA) The Bock HG (Hermetic Gas-cooled) range of semi-hermetic compressors offers traditional suction gas-cooled compressor state of the art technology. These compressors of the highest quality standard excel in their running comfort, easy maintenance, efficiency and reliability. Suitable as standard for conventional or chlorine-free HFC refrigerants. The HA (Hermetic Air-cooled) range, specially engineered by GEA Bock, is available for deep-freezing applications, in particular for use with the refrigerants R22 and R404A. ºº...

Electronic Controls Progressive technology in and around the compressor GEA Bock has been the pioneer under this motto in developing technical solutions which set the benchmark for energy and efficiency, operating safety and reliability, not only for compressors but for the whole refrigeration plant.

Electronic Controls Motor Protection Temperature safety drive for the drive motor The exceptional feature is that the monitoring function and mains availability are shown by coloured LED's. There are no complicated or time-consuming defect locating processes. The MP10 also provides the usual functions as standard, e.g. a recon- nection preventing device, a reset, free terminals for PTC temperature sensors (e.g. heat protection thermostat) and other useful items.
