Custom Control Panels for Hazardous (Classified) Locations

Hazardous Area Classifications & Electrical Protection

When considering the safety of employees working at industrial plants, fires and explosions are a risk employers must account for and protect against. In geographic areas where natural disasters are common, for example in the southeast United States coastal region where hurricanes often make landfall, organizations must also protect their electrical equipment and components from outdoor elements like water submersion, rain, dirt, etc.

At PSI Control Solutions, we specialize in the design and fabrication of custom control panels for hazardous locations in accordance to NEMA standards to provide maximum safety and protection against life and property loss.

What Is a Hazardous Area/Location?

A hazardous area is a place where any concentration of flammable gases, vapors, or dusts are present. Any control panel fabricated for a hazardous area must be clearly marked and labeled to designate where the panel can and cannot be used. This includes:

  • Class
  • Division
  • Group
  • Maximum temperature or temperature ranged for safe operation (based on a 40 degree Celsius (104 degrees Fahrenheit) ambient
  • Other special conditions (ask a manufacturer for special conditions)

Some of the industrial applications our control panels for hazardous locations help protect include:

  • Oil refineries
  • Gas refineries
  • Landfills
  • Water purification plants
  • And more

Electrical Protection in Hazardous Areas/Locations from PSI

At PSI Control Solutions, we engineer custom control panels built to operate in environments where concentrations of flammable gases, vapors, liquids, or combustible particles pose risks of ignition and/or explosion.
Our team of engineers design UL- and CUL-certified panels for hazardous locations, as well as NNNY- and NNNY7-certfied composed with a heavy metal cast NEMA 7 explosion-protected enclosures. This includes control panels for use in:

  • Class I, Division 1 (Explosion-Proof)
  • Class I, Division 1 (Purged/Pressurized Type X)
  • Class I, Division 2 (Purged/Pressurized Type Z)
  • Class I, Division 2 (Nonincendive)
  • Class I, Groups A, B, C & D
  • Class I, Division 2, Groups A, B, C & D
