Ex-Proof System For process products which are flammable or machines that must be washed with solvents or are installed in areas with risk of explosion, we collaborate with customers to address these specific elements and evaluate the risk associated with each situation. We help you to address their AtEx marking, along with estimating the risk generated by the machine itself (in case it needs to process flammable compounds). Flammable compounds, if ignited (e.g. by a spark), cause explosions, which may be fatal.
