Explosion-proof communication systems
Industrial processes of mining operations, transportation and processing of mineral products in different branches of industry are related with real risk of forming the explosive environment in areas of processing stations, storage facilities and esplanades.
Explosion-proof communication equipment should be used at the explosion industrial sites.
In addition to this forming of the explosive environment is possible in cases of operating practices violation, accidents, equipment, apparatus and piping explosion-proof safety violations.
At the same time execution of industrial processes is impossible without using of various electrical equipment including illuminating equipment. Its save exploiting depends on certain characteristics of explosive environment. To ensure save exploiting it is important to know equipment requirements.
"Arman" company specializes in providing explosion-, dust- and moisture-proof electrical equipment for all classes of explosion hazard areas and temperature groups of explosive mixtures (with the exception of methane in deep mining) and offers the following equipment for explosion-proof communication systems building:
- explosion-proof digital interphone DW Ex;
- explosion-proof analogue interphone AW Ex;
Activity of "Arman" company is based on observance of labour safety standards in compliance with Russian and European standards IEC. "Arman" company works in collaboration with the testing laboratory of explosion-proof and mining electrical equipment, planning institutions and has got test reports and summaries. "Arman" company manufactures explosion-proof communication devices and alarm systems with explosion safety system named "spark-safe electrical circuit" for the following objects:
- enterprises with dangerously explosive manufacturing environment of metal mining industry including coal mines and pits with dangerous conditions of gas, dust and sudden gas releases (group I);
- enterprises of fuel-energy complex, oil and gas-refining and chemical industries, objects with dangerous production areas (group II);
- generally industrial objects (telephone sets for technological areas and for external mounting).
