Chemicals
Process industry
The process industry processes the most diverse range of substances and materials in the context of chemical, biological, physical and/or technological processes. The industry is subdivided into various branches, such as, for example:
The generation of dust and the use and handling of aggressive fluids mean that there are frequently difficult ambient conditions in these industries, under which machinery and systems must, nonetheless, continue to function correctly. The subject of explosion safety also plays an important role here.
ROSE Systemtechnik supplies an extensive range of Ex equipment to assure maximum safety for your processing plant. This range includes:
Sub-industries
Systematic explosion prevention
There is a danger of explosion wherever combustible gases, vapours or particulates are stored, processed or handled. Explosion-endangered zones can also occur in the following environments, in addition to the process industry:
Within the EU, the requirements for the safe use of electrical equipment in explosion-endangered areas are strictly regulated by the ATEX directive. Processing industry companies must adhere to wide-ranging national and international codes of practice and standards in order to assure maximum safety during operation. The reason: it is not always possible to prevent the formation of explosible atmospheres by means of primary or secondary safety measures.
