Application-Driven Design for Hazardous Areas

Not all hazardous environments require the same explosion-proof solution.

In flammable and explosive environments, the real risk lies not merely in whether explosion protection is implemented, but in whether the chosen solution aligns with actual operational tasks. Different hazardous zones, working methods, and operational frequencies demand vastly different design requirements for explosion-proof equipment.

Our explosion-proof equipment always follows one principle: first understand the application scenario, then design the explosion-proof solution.

Custom explosion-proof designs tailored to different hazardous zones

In hazardous environments, “Zone” classification is merely the starting point—not the end goal of design.

Zone 1 / Zone 2

Flammable Gas Environments

In gas environments, explosion-proof design focuses on:
  • Preventing electrical sparks from becoming ignition sources
  • Controlling surface temperatures to avoid igniting gases
  • Ensuring safety during frequent start-ups, shutdowns, and continuous operation
  • Flammable Gas Environments

    Zone 21 / Zone 22

    Combustible Dust Environments

    In dusty environments, the focus of explosion-proof design shifts to:
  • Preventing dust accumulation from causing overheating
  • Controlling electrostatic charge buildup and discharge pathways
  • Ensuring structural integrity and long-term stable operation
  • Combustible Dust Environments

    operational task determines equipment structure

    In hazardous environments, what equipment does matters more than what it’s called.

    When designing explosion-proof equipment, we first focus on the task itself, such as:

    • Is it for inspection or continuous production transfer?
    • Is it for short-term use or 24/7 continuous operation?
    • Is it high-frequency start/stop or steady-load operation?

    These questions directly determine:

    • Explosion-proof system configuration logic
    • Power and control system selection
    • Structural design and safety redundancy levels

    Different tasks within the same hazardous area must never employ identical solutions.

    Explosion-Proof Rating and Customized Standards

    Different application scenarios impose varying requirements on explosion-proof equipment

    The “priority sequence” for explosion-proof design also varies significantly depending on the specific application scenario.

    Hazardous Environment Warehousing

    Hazardous Environment Warehousing

    • Focus on aisle adaptation and stacking stability
    • Prioritize high-frequency start/stop operations and personnel safety coordination
    • Explosion-proof design must balance efficiency with safety margins
    Hazardous Environment Production Lines

    Hazardous Environment Production Lines

    • Greater emphasis on continuous operation capability

    • Higher demands on system stability and load management

    • Explosion-proof design must account for production cycle times

    Inspection and Auxiliary Operations

    Inspection and Auxiliary Operations

    • Greater emphasis on flexibility and accessibility
    • Requires maintaining safe response in complex environments
    • Explosion-proof design must cover multiple abnormal operating conditions
