FAQ

  • Q1: What does “Explosion-proof” mean for an explosion-proof control station?
    • A: It signifies the device’s ability to prevent the ignition of a surrounding explosive atmosphere through specialized construction that contains internal sparks or limits energy levels.
  • Q2: In which industries are explosion-proof operator stations primarily used?
    • A: They are widely used in any environment with flammable gases, vapors, or dusts, such as oil & gas platforms, refineries, chemical plants, and food processing facilities.
  • Q3: Can we open the operator station ourselves for maintenance or component replacement?
    • A: No. Only specially trained and authorized personnel may open Ex control stations, and only in a confirmed safe area, to avoid compromising explosion-proof integrity.
