ATEX Zone 2 & Class 1 / Div 2 Panel PCs: Certified Explosion Protection for Hazardous Areas

In industries where flammable gases, vapors, or dust may create explosive atmospheres, the strictest safety requirements apply. ATEX Zone 2 and Class 1 / Division 2 Panel PCs are specifically certified for safe operation in these hazardous environments (Ex zones). They deliver the industrial HMI performance expected from modern systems while eliminating any possibility of sparks or critical heat generation that could trigger an explosion.

Key Advantages of Explosion-Protected Panel PCs

  • International Ex certifications: The systems are rigorously certified according to European ATEX directives (Zone 2/22) as well as North American Class 1, Division 2 (C1D2) standards, enabling worldwide deployment in hazardous environments.

  • Non-incendive design: Internal components and electrical circuits are engineered to prevent electrical sparks or hot surfaces from occurring, even in fault conditions, eliminating ignition risks in hazardous atmospheres.

  • Functional safety for 24/7 operation: Despite their hermetically sealed design, the systems provide modern processor performance, durable enclosure materials (often corrosion-resistant stainless steel), and highly precise touch operation.

  • Sealed cable routing: Interfaces are protected using specialized explosion-proof cable glands or intrinsically safe industrial connectors, completely preventing gases or dust from entering the enclosure interior.

Ideal Applications in the Process Industry

  • Oil, gas, and petrochemical industries: Installed directly on drilling platforms, refineries, pipeline monitoring stations, or tank farms where volatile gases may be permanently present.

  • Chemical and pharmaceutical industries: Visualization and control of mixing and filling systems where flammable solvents or chemical substances are processed.

  • Mills, silos & wood processing: In environments where fine organic dusts (such as flour, grain, or wood dust) can combine with oxygen to create highly explosive atmospheres (Zone 22).

Frequently Asked Questions about ATEX Zone 2 and Class 1 / Div 2 Systems (FAQ)

What is the difference between ATEX Zone 2 and Class 1 / Div 2?

The primary difference lies in the regional regulatory framework and testing standards. ATEX is the legally required directive within the European Union and classifies hazardous environments into zones (Zone 2 for gases, Zone 22 for dust). Class 1 / Division 2 is the equivalent classification system according to the National Electrical Code (NEC) in North America. Both standards describe environments where explosive substances are unlikely to occur during normal operation and only appear temporarily.

Can ATEX Zone 2 PCs also be used in Zone 1 environments?

No. Devices certified for Zone 2 must never be used in the more critical Zone 1 environment, where explosive atmospheres may frequently occur during normal operation. Conversely, devices certified for Zone 1 may also be operated safely in Zone 2 areas. Always ensure the exact hazardous area classification of your facility during system planning.

Can touchscreens be operated normally in hazardous Ex zones?

Yes. Our ATEX and C1D2 Panel PCs use specially validated capacitive (PCAP) or resistive touchscreens designed to prevent any ignition hazard caused by static discharge or physical pressure during operation — even when used with industrial work gloves.
