GEA Bock ATEX Compressors Semi-hermetic Compressors in Explosion-risk Environments engineering for a better world

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. In this brochure we present you our...

Production Program Semi-hermetic compressors HG (HA) The GEA 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. -- Single-stage --...

ATEX Compressors At a Glance ATEX compressors Semi-hermetic compressors for explosion-risk environments Within Union, electrical in explosive atmospheres must comply with the ATEX (ATmospheres EXplosibles) Our solutions are customeroriented because they are low-priced, energy-efficient, long-lasting and tailored to your indivi­ conditions. The system designer must use correspondingly marked and certified components for these applications. GEA Bock is the first European manufacturer who offers compressors which are conform to ATEX machine category 2. dual needs. Information on the...

ATEX Compressors General Information General information about ATEX Explosion protection and ATEX According to the dictionary, an explosion is a "sudden change in forces based on the expansion efforts of gases and vapours". Explosions are accompanied by an abrupt and usually simultaneous increase in temperature and pressure. Here it is possible to reach values excee- ding 2000°C and 10 bar. The Professional Association of the Chemica Industry estimates that in Germany alone, altogether three minor to medium explosions occur every day. There is an explosion-risk in nearly all process...

ATEX Compressors General Information The ATEX directives 1. EC directive 1999/92/EC (ATEX 137) It contains “minimum requirements for improving the safety and health This stipulates the requirements made of the products used in explosion- protection of workers potentially at risk from explosive atmospheres“. risk areas. This refers to: It stipulates above all the requirements made of workplaces, including: -- Machines and protection systems for intended use in explosion-risk -- Compilation of explosion protection documents with a comprehensive -- Safety, control and regulating devices...

ATEX Compressors General Information Zone allocation The obligations of the machine operator include drawing up a so-called explosion protection document, as stipulated in ATEX 137. This also Zone allocation includes an appraisal of the explosion risks. Accordingly, certain zones are to be introduced. Explosion risk areas are broken down into zones and marked accordingly, depending on the frequency and duration with which explosive atmospheres occur: Zone 0: The explosive atmosphere is present constantly, for long periods of time or frequently. Zone 1: The explosive atmosphere is...

ATEX Compressors General Information explosion-risk areas - The machine owner must draw up an explosion protection - The employer must provide employees with adequate, appropriate nstructions about explosion protection - In the case of dangerous work, written work permit must be obtained from the machine owner before commencing - Explosion-risk areas must be marked with the warning sign at the access points - Ignition sources (smoking, naked lights, soldering) must be prohibited - Unauthorised access to the area must be prohibited by clear, indelible warning signs - Working equipment must...

ATEX Compressors General Information What does this mean for refrigerating machines? Equipment in explosive atmospheres has to comply with ATEX Accordingly the plant operator should only use correspondingly requirements, when operating within the European Union. marked and identified components with the necessary documentation (e.g. manufacturer’s declaration or declaration of conformity). According to ATEX requirements all electrical and mechanical equipment must be examined. The declarations issued by the component manufacturers only refer to the product itself. All equipment is defined...
