Can you supply overhead stirrer motors for ATEX areas? None of our standard overhead stirrers are ATEX (Ex) compliant. Even if you sourced an ATEX-certified stirrer motor, it would not mean that the rest of the system is suitable for ATEX environments. The best option is for the overhead stirrer (and overall system) to be situated in a non-ATEX area if possible, e.g. inside a fume hood and operating below the lower explosive limits of any flammable materials, if your site safety experts determine this is acceptable.
