Worker safety in the workplace is becoming a major concern for employers, and initiatives around the world are increasing to contribute to it. ATEX, IECEx, INMETRO, EAC, CN-Ex, UL, etc. are certification programmes that ensure the safety of users in hazardous atmosphere environments. At the European level, any manufacturer who wants to offer a hardware solution for use in potentially explosive atmospheres must comply with the ATEX Directive 2014/34/EU. Industrial processes developed for the pharmaceutical industry, the chemical industry, mining, wastewater management, refinery operations or industrial painting include numerous dosing stations that are dimensioned according to the application. Once the dosing needs are expressed in an ATEX environment, the range of available solutions is significantly reduced, taking into account the constraints to be respected. World leader in proportional dosing solutions without electricity and with 45 years of experience in industrial dosing, Dosatron meets the requirements of ATEX regulations in zone 0 or 20. Dosatron technology enables in-line dosing without electricity of a wide range of additives used in industry, whether liquid or soluble, acid or alkaline, liquid or viscous. As a simplified alternative to equivalent electrical technologies, it guarantees a high level of accuracy while helping to optimise construction and maintenance budgets.
