Everything designers, technical managers and industrial buyers need to know about ATEX certification applied to rotary joints. In industrial processes where flammable fluids, combustible dusts and potentially explosive atmospheres coexist, every component must be designed, certified and managed according to precise criteria. The rotary joint — the element that transfers fluids (air, water, steam, oil, etc.) between a stationary part and a rotating one — is no exception. In the pharmaceutical, chemical and food industries, where safety regulations are among the strictest in the world and operating conditions may generate explosive atmospheres, ATEX compliance is not optional: it is a design requirement.
