Explosion-Proof Robot “Ex d IIB T4” Rating Guide
Why Do Robots in Paint Booths Need to Be Explosion-Proof? Paint booths contain suspended paint particles and solvent vapors, which can ignite or explode instantly upon contact with an open flame or a high-temperature surface. Standard industrial robots - with their motors, drives, and switches - are potential ignition sources; a single spark could trigger a disaster. Therefore, the entire robotic system, from the robot arm itself to the control cabinet, must be explosion-proof and compliant with relevant safety standards. This is not merely an option; it is a critical safety requirement and a mandatory criterion for environmental impact assessment (EIA) approval. Selecting the wrong explosion-proof rating either creates a serious explosion hazard or leads to unnecessary, excessive costs. What Does "Ex d" Mean? "Ex" is the general designation for…
