Environmental Resistance Options

Many ETI customers operate in harsh climates ranging from the deserts of Australia to the frozen tundra of Alaska.  It is important to conduct proper studies and tests to ensure ETI enclosures hold strong against the elements and/or disasters in their proposed region of operation. Recent fulfilled requests and testing have been for:

  • Water Resistance and Dust Resistance up to NEMA 4x or IP66
  • Explosion Resistance
  • Hurricane/Typhoon/Cyclone Resistance up to 224mph
  • Earthquake Resistance
  • Salt Water Resistance
