Flameproof Motors

Dietz offers some of the most reliable electric motors on the market today. Made with safety and efficiency in mind, all of our products meet the requirements established by the National Fire Protection Association. We’re also certified by a number of top safety organizations, including FM, UL, and the Canadian Standards Association.

Dietz particularly specializes in supplying and servicing flameproof motors. Our flameproof products are designed to enclose flares and sparks as soon as they’re generated, halting fires at the source and preventing explosions outside of the motor from occurring.

Applications and Classifications of Flameproof Motors

Any environment that contains vapor, dust, gas, and other flammable substances can pose  hazards to workers who regularly operate electric motors. If an explosion happens inside a machine’s motor in such a flammable setting, it could trigger a greater explosion outside of it, threatening the entire workplace in the process.

Flameproof motors are built to contain very hazardous contents within the motor. By isolating these hazards from the surrounding environment, they protect workers and facilities alike from unwanted accidents that could derail operations while ensuring that production continues without a hitch.

Hazardous motors are classified into two separate classes that are used to establish the kind of motor best for particular environments:

  • Class I: Areas with vapors, liquids, gases
  • Class II: Areas with dust
  • Class III: Areas with flammable fibers or lint

Each class also has a subgroup: A – G. Each group indicates how elements are affected when explosions occur. The labels are  organized by the severity of the requirements within each specific motor design:

  • Groups A – D: Classified under Class I, due to their vapor or gas form.
  • Groups E – G: Classified under Class II, due to their dust form.

In addition to motor classes, hazardous locations are further classified into divisions:

  • Division 1: Explosive elements almost always present on location.
  • Division 2: Explosive elements inside operator-handled storage tanks or containers with potential of spillage or leakage in event of equipment malfunction.
