A C2D2 rating refers to a classification for hazardous locations in industrial environments, especially for explosion-proof or intrinsically safe equipment, like computers.
Here’s a breakdown of what C2D2 means:
C2: Class II
The classification applies to areas with hazardous combustible dust.
- These are locations where flammable or combustible dust may be present in the air in sufficient quantities to pose a fire or explosion risk.
- Examples include grain mills, sugar processing facilities, and chemical plants.
D2: Division 2
- This specifies that hazardous materials (combustible dust) are not normally present in the atmosphere but could become present under abnormal conditions.
- For example, combustible dust might only accumulate or disperse if there’s equipment failure, leaks, or an accident.
What a C2D2 Rating Means for Explosion-Proof Computers
An explosion-proof computer with a C2D2 rating is certified for use in environments with:
- Class II hazards (combustible dust),
- In Division 2 areas, where dust isn’t constantly present but may appear under abnormal circumstances.
Such computers are ruggedized and specifically built to:
- Prevent sparks or overheating that could ignite combustible dust.
- Seal components to avoid dust ingress into critical areas.
Where C2D2-Rated Computers Are Used
- Food processing plants
- Grain storage silos
- Chemical manufacturing
- Textile production facilities
- Woodworking facilities
If you’re looking for C2D2-rated explosion-proof computers, they are often used in industrial and hazardous locations where safety and compliance with regulations like NFPA 70 (NEC) or ATEX are required. Tangent specialize in building these types of rugged computers for critical industries.
