1. Extreme Conditions Where Electronics Can’t Survive

In some industrial environments, electronics barely stand a chance:
  • Scorching desert heat reaching up to 50°C
  • Persistent salt-laden air on offshore platforms
  • Continuous exposure to dust and corrosive gases in chemical plants
  • Condensation and internal moisture caused by drastic temperature shifts

The challenge intensifies in hazardous areas like Zone 1 and Zone 2, where equipment must not only survive harsh conditions but also meet strict explosion-proof safety standards. Standard explosion-proof devices often can’t meet complex functionality needs, while regular equipment cannot operate safely in such zones.

2. Pressurized Explosion-Proof Enclosures: A Survival System for Non-Ex Equipment

TLS pressurized explosion-proof enclosures are designed to create a safe, stable, and controllable micro-environment for non-intrinsically safe equipment. These enclosures:

  • Isolate from flammable gases, enabling compliance with Zone 1/Zone 2 standards
  • Protect against dust, salt spray, and moisture, significantly extending equipment lifespan
  • Mitigate temperature extremes, ensuring consistent performance

The pressurization system delivers a continuous clean airflow, supported by multi-stage gas purging and differential pressure control, forming an invisible barrier that shields internal devices from external hazards.

3. Facing the Challenge with More Than Just Design — We Rely on Customization

No two projects are the same. That’s why TLS doesn’t offer off-the-shelf solutions — we deliver fully customized system designs, tailored to site-specific conditions, including:

  • High-temperature environments: Dual-layer insulation with integrated ventilation and cooling
  • Offshore/salt-laden air: Triple-layer epoxy coating and high-strength weather-resistant steel
  • Dust-heavy factories: Sealing performance up to IP66
  • Humid tropical climates: Optional dehumidifiers or anti-condensation systems based on project requirements

From design and prototyping to assembly, certification, and delivery, TLS ensures fast project turnaround and smooth system retrofits without delays.

4. When There’s No Room for Error, TLS Secures the Last Safe Space

We often hear from clients: “We don’t even know how to deploy this equipment in such a hostile environment.”
Our answer: Keep using the brand you trust for your equipment — TLS will handle the rest.

What we deliver is not just a metal enclosure, but a complete system solution that allows non-ex equipment to operate legally, safely, and reliably in the world’s harshest industrial zones.

Why Choose TLS?

  • Over a decade of experience in explosion-proof and functional container customization
  • Deep understanding of real-world Zone 1/Zone 2 project requirements — built on hands-on experience, not just lab tests
  • Rapid adaptation to multi-brand equipment integration
  • Support for third-party explosion-proof certifications (ATEX, IECEx, etc.) for global deployment
  • Fully customizable — from structure to ventilation — tailored to your project’s unique extreme conditions

​In industries where flammable gases and vapors are a constant threat, like oil, gas, and chemicals, explosion-proof containers aren't just an option—they're a necessity. These specialized units are engineered to create secure environments, particularly in hazardous gas environments classified as Zone 1 and Zone 2. Beyond robust construction, they must meet rigorous standards for electrical systems, ventilation, and international safety certifications to ensure the highest level of protection for personnel and equipment.

Key Features That Make Explosion-Proof Containers Indispensable
What sets an explosion-proof container apart? It's a combination of meticulous design and advanced technology focused on preventing and containing explosions.
  • Explosion-Proof Structural Design: Built with high-strength, weather-resistant steel, these containers are hermetically sealed to prevent the ingress of flammable gases. They feature thickened steel plates and reinforced frames designed to withstand the immense impact of an internal explosion.
  • Explosion-Proof Electrical System: All electrical components, from lighting and switches to air conditioners, must adhere to international standards like IECEx, ATEX, and China's GB 3836. The use of explosion-proof cables and sealed junction boxes eliminates the risk of sparks or arcs that could ignite flammable gases.
  • Ventilation & Gas Detection: To prevent the dangerous accumulation of gases, each container is equipped with explosion-proof ventilation fans. Crucially, integrated explosion-proof gas detectors continuously monitor for hazardous gases such as hydrogen (H₂) and hydrogen sulfide (H₂S), providing real-time alerts.
  • Fire Resistance & Insulation: Safety extends to fire protection. These containers incorporate high-performance fireproof materials, like fire-resistant rock wool, and comply with international fire safety standards such as EN 13501 and UL 1709, ensuring structural integrity even under extreme heat.
  • Corrosion & Weather Resistance: Designed for longevity in harsh conditions, they feature C5 corrosion-resistant coatings, offering superior protection against salt spray, acids, and aggressive chemicals. This makes them ideal for demanding environments like offshore drilling platforms and chemical processing plants.

Technical Requirements: The Backbone of Explosion-Proof Safety
For an explosion-proof container to be truly effective, it must meet a specific set of technical criteria:
  • Hazardous Area Classification (Zone 1 & Zone 2): Compliance with IEC 60079 and ATEX directives is fundamental, certifying their suitability for environments with explosive gas mixtures.
  • Clear Explosion-Proof Markings: Every piece of explosion-proof equipment must bear clear certification markings, indicating its compliance. Examples include:
          o ATEX: Ex db IIB T4 Gb
          o IECEx: Ex de IIC T5 Gb
          o GB 3836 (China): Ex d IIB T4 Gb
  • Advanced Electrical & Ventilation Systems: 
          o An explosion-proof power distribution system that adheres to IEC 60079-14 is mandatory.
          o A robust built-in ventilation and air exchange system is critical for rapidly purging hazardous gases.
          o Explosion-proof gas sensors, compliant with IEC 60079-29-2, must be properly calibrated with accurate alarm                           thresholds.
  • Rigorous Fire Resistance & Corrosion Standards: 
          o Walls must offer fire resistance of 60-120 minutes (e.g., EN 13501-2).
          o Protection against fire for 30-60 minutes (e.g., UL 1709) is essential.
          o For offshore use, A60 modular fire protection (60 minutes) is required.
          o Structural strength must meet ISO 1496.
          o C5 corrosion protection is vital for extreme industrial and offshore conditions, guaranteeing a service life of over 15                     years.

Navigating International Explosion-Proof Standards & Certifications
To ensure your investment is globally compliant and reliable, look for containers certified by leading international bodies:
  • IECEx (International): Guarantees compliance with IEC 60079 standards.
  • ATEX (European Union): The definitive certification for equipment in explosive atmospheres within the EU.
  • UL (United States): Includes UL 1709 fire resistance testing.
  • CSA (Canada): Provides crucial explosion-proof certification for electrical equipment in Canada.
  • CNEX/NEPSI (China): Adheres to GB 3836 standards, equivalent to IEC 60079.

How to Select the Right Explosion-Proof Container for Your Needs
Choosing a qualified explosion-proof container requires a systematic approach to ensure maximum safety and compliance:
  1. Identify Your Hazardous Area: Clearly define whether your environment is Zone 1 or Zone 2 to match the appropriate explosion-proof rating.
  2. Verify Electrical System Compliance: Confirm that all electrical systems meet ATEX, IECEx, and GB 3836 standards.
  3. Assess All Safety Features: Ensure the ventilation, gas detection, fire resistance, and corrosion protection systems adhere to all relevant industry regulations.
  4. Prioritize Certified Suppliers: Always choose suppliers with IECEx, ATEX, and UL certifications to guarantee adherence to international safety benchmarks.

In high-risk industrial settings, explosion-proof containers are more than just equipment—they are vital safeguards for both personnel and critical assets. By understanding their key features, technical requirements, and international certifications, you can make informed decisions that ensure long-term safety and operational reliability.
