Flameproof (Ex d) motors that contain an internal explosion and prevent ignition of a surrounding hazardous atmosphere.
Every field is optional - tell us what you know and we will confirm the rest in the quotation.
Representative image. The actual product, make and appearance depend on the supplier and your specification.
Flameproof (Ex d) construction lets an explosion occur inside the enclosure without igniting the atmosphere outside, so certification details matter more than anything else. Get the area classification: zone, gas group (such as IIA, IIB or IIC) and temperature class.
Mistakes include painting over flamepaths, opening a motor after energising, and repairs by workshops without hazardous-area experience. Document the installation for inspection. For hoists, see flame proof motor with brake; for lower-risk Zone 2 there is also a non-sparkling motor. A qualified engineer should confirm selection.
Ratings, dimensions and certification are confirmed against your enquiry. Use Send an enquiry and our engineers will respond within 24 hours.
Gas groups (IIA, IIB, IIC) classify gases by how easily they ignite and how narrow a gap a flame can pass. The motor's flamepath must suit the group. A motor certified for a more demanding group can usually serve a less demanding one.
Repairs must keep flamepaths, clearances and certification intact, so use a workshop experienced with hazardous-area equipment. Incorrect repairs can make the motor unsafe, even if it runs. Records of repairs should be kept for inspection.
