Exproof HMI in Grain and Dusty Processes: Dust Zones, Not Just Gas

Explosive atmospheres are not only gas. Grain, flour, sugar, plastic powder and metal dust create dust Zones (typically 20 / 21 / 22). “We have a gas certificate” is not enough—dust protection type and enclosure integrity must be verified separately.

Field examples

  • Under-silo weighing and dosing
  • Pneumatic conveying lines
  • Bagging / big-bag stations

Watch-outs

  1. Dust build-up on cooling paths and gaskets
  2. Static control and earthing continuity
  3. Cleaning procedures vs hot-work rules
