TLS news & blogs

In the design of functional containers, safety and cost often present a difficult trade-off. As a long-term supplier for the oil & gas, offshore, and renewable energy industries, TLS faces a central question in every product development process: How can we ensure reliability and safety while helping customers maintain cost efficiency?

1. Redundancy: A Guarantee of Safety, but Not the Only Solution
In many standard designs, safety redundancy is usually achieved by adopting dual systems—such as twin fans, dual power supplies, or dual control loops. This approach undoubtedly improves fault tolerance and allows the system to keep operating even if one component fails.However, excessive redundancy also results in higher upfront costs and additional maintenance burdens.
At TLS, we do not equate “safety” with “simply doubling equipment.” Instead, we combine risk assessment with engineering judgment to determine the right balance for each project. For instance, some containers are not necessarily equipped with dual fans; the decision depends on the operating environment, duty cycle, and maintenance conditions.

2. Cost Optimization: Precision Investment, Not Simple Reduction
Cost optimization does not mean “cutting corners.” Rather, it means investing precisely where it matters most to maximize value.

• For critical aspects such as positive pressure explosion protection, structural strength, and fire resistance, TLS makes no compromises.
• For flexible areas such as ventilation methods, wiring layouts, or monitoring systems, we provide tailored options based on customer budgets and operating conditions.

This approach ensures that customers are not paying for unnecessary “over-design,” while still receiving robust safety protection at key points.

3. Customization: Tailored Safety Strategies
TLS’s design logic always starts with the customer’s real-world needs, not with a one-size-fits-all template.

• For containers deployed on offshore platforms, we prioritize corrosion resistance, fire protection, and redundant ventilation.
• For land-based renewable energy projects, we focus on modularity, ease of maintenance, and transport adaptability.

This context-specific design philosophy ensures that TLS containers not only meet international standards but also deliver practical value in real project applications.

Conclusion
Safety redundancy and cost balance are not opposites. Through scientific evaluation and deliberate engineering trade-offs, TLS ensures that every functional container we deliver achieves “safe and reliable + cost-efficient” performance.At TLS, the optimal solution is never about having “the most configuration,” but always about having “the right configuration.”

In high-risk industries such as oil & gas, chemical processing, and hydrogen electrolysis, the operating environment often contains flammable gases or vapors. This requires containers used in such areas to comply with strict explosion-proof standards.

As a provider of customized functional container solutions, TLS fully understands the differences between Zone 1 and Zone 2 hazardous areas and adapts container structure, materials, and systems accordingly.

1. Zone 1 vs Zone 2 – Risk Levels Define Design Requirements

• Zone 1: Areas where explosive gas atmospheres are likely to occur during normal operation.
• Zone 2: Areas where explosive gas atmospheres are unlikely during normal operation, and only occur for short periods under abnormal conditions.

This distinction means that Zone 1 applications demand higher and more consistent safety performance, while Zone 2 designs may allow for certain optimizations and cost-effectiveness trade-offs.

2. Container Structure – From Sealing to Ventilation

• Positive Pressure Explosion-Proof System

For both Zone 1 and Zone 2 applications, TLS equips containers with positive pressure ventilation systems with dedicated control logic, maintaining a clean internal atmosphere and preventing the ingress of flammable gases.

Zone 1 applications require a redundant fan system (N+1) with a backup power supply to ensure system operation. The standby fan has a fast gas replacement start-up mode and incorporates gas leakage detection and automatic power-off to ensure a safe positive pressure environment is maintained at all times inside the enclosure.

For Zone 2, a single-fan configuration can be used with adjustable start/stop strategies based on on-site risk levels and operating cycles, optimizing cost-performance balance.

• Sealing and Material Treatment

All welding seams, pipe penetrations, and door frames must meet airtightness standards. Materials must comply with fire and corrosion resistance requirements, especially for marine or high-humidity environments.

3. Electrical and Control System Explosion-Proof Strategies

• Selection of Electrical Components

In Zone 1, all equipment such as lighting, sockets, and air conditioners must be explosion-proof certified (e.g., Ex d or Ex e under ATEX or IECEx standards). Zone 2 can allow certain non-explosion-proof devices, but they must be protected through positive pressure or gas detection systems.

• Control Logic Differentiation

Zone 1 systems often have redundant controllers and independent protection circuits to ensure no single-point failure compromises safety. Zone 2 allows for simplified control but still requires essential features such as power cut-off, pressure alarms, and gas concentration monitoring.

4. External Interfaces and Explosion-Proof Penetrations

Every cable or pipe penetration is a potential leakage point—especially in high-risk Zone 1 areas—so safety measures must be implemented from the source:

• Cable entries must use explosion-proof cable glands (e.g., EExe certified) with secure compression seals.
• Pipework should use flexible connections with explosion-proof fittings to avoid damage from vibration or tension.
• All interface positions and routing must avoid high-temperature or high-vibration zones, while leaving sufficient maintenance space.

5. Design Adaptation Process – Starting from Risk Assessment

TLS participates in the client’s risk assessment process from the very beginning. Based on the area classification drawings provided, we develop targeted explosion-proof designs to ensure every detail meets the relevant standards.
Upon delivery, TLS also provides complete design drawings, interface documentation, and explosion-proof compliance files for client review and record-keeping.

Conclusion – True Adaptation is Safety in the Details

Adapting to Zone 1 and Zone 2 requirements is not simply a matter of choosing different components—it requires a holistic approach to container structure, ventilation, electrical systems, and safety logic.

Through project-based design, component-level certification, and system-level validation, TLS ensures every explosion-proof container is not only compliant but also safe, reliable, and maintainable.

In high-risk experimental environments involving hazardous chemicals, flammable gases, or explosive dust, positive pressure lab containers have become the go-to choice for research institutions, inspection units, and industrial lab projects. With their safety, stability, and controllability, these units offer a critical safeguard for personnel and processes.

However, a positive pressure lab container that’s truly “ready for use” is far more than just a fan installed in a steel shell. Its safety and performance hinge on the detailed engineering and quality behind every structural element.
At TLS, a specialized manufacturer of functional container systems, we have identified five key structural features that determine whether a positive pressure lab container is truly usable, reliable, and deliverable.

1. Airtight Structure – The Foundation of Everything
The primary requirement of a positive pressure lab container is the ability to maintain a stable internal pressure. This demands a high level of airtightness. TLS ensures this through:

• Double-layer sealing strips on doors for enhanced closure tightness
• Airtight cable gland systems at pipe entry points
• Full-welded seams with thorough inspection and repair to eliminate leaks
• Reinforced sealing components on doors, hatches, and viewing windows

Insufficient airtightness not only compromises positive pressure but can also lead to the escape of harmful substances during experiments—a major safety hazard.

2. Ventilation Interface and Air Duct Design
The direction of the air ducts and the location of the ventilation connections need to be determined at the design and manufacturing stage of the box, which plays a decisive role in the performance of the entire ventilation system.
TLS provides:

• Standard or customized ducting interfaces (supporting top-down, side-top, or other configurations)
• Optimized internal air paths based on airflow volume and pressure specifications
• Well-planned duct layouts that improve system stability, prevent uneven airflow, and reduce the risk of equipment overload or dead zones

3. Explosion-Proof Electrical Interfaces and Cable Routing
For lab containers intended for Zone 1 or Zone 2 hazardous areas, the container must integrate with explosion-proof systems. TLS supports this by:

• Providing cable entry fittings compliant with Ex e or Ex d standards
• Pre-installing or reserving mounting supports for explosion-proof lighting, distribution boxes, and control panels
• Pre-routing cable trays and electrical paths based on customer drawings
• Ensuring internal wiring follows IECEx structural guidelines, making on-site integration fast and compliant

4. Safety Monitoring and System Compatibility
Safety monitoring is a key consideration in our lab container designs. Depending on client needs, we offer:

• Sensor installation ports: The system is equipped with smoke sensors, differential pressure sensors and temperature sensors to achieve safety monitoring and environmental linkage control. In response to customers' personalized demands, we can also reserve additional sensor installation holes as required to facilitate future expansion and functional upgrades.
• Cooperation on safety device integration: Our team actively assists with the installation of emergency stop buttons, audible/visual alarms, and fire suppression systems

5. Customizable Modular Design
TLS lab containers feature a high degree of modularity, allowing flexible configuration based on project requirements:

• Dimensions can follow standard ISO footprints (10ft/20ft/40ft) or be fully customized
• Options to add observation windows, access doors, and maintenance hatches
• Support for multi-container linkage and rapid field deployment through modular connections

Conclusion
A positive pressure lab container is not just a sealed box—it’s a carefully engineered system that integrates airtight construction, ventilation planning, electrical safety, monitoring readiness, and modular design.
TLS is dedicated to the development and manufacturing of functional containers and explosion-proof safety modules. With extensive industry experience, we work closely with clients to deliver high-standard lab environments that are safe, tailored, and field-ready.

In high-risk industries such as energy, chemicals, energy storage, and intelligent manufacturing, pressurized explosion-proof containers are widely used to house critical equipment like electrical control systems, lithium batteries, and sensor modules.

One common question from clients is:
“If a device or battery inside the container catches fire or explodes, will flames or sparks leak into the external environment and cause greater danger?”

As a specialized manufacturer of functional explosion-proof containers, TLS addresses this concern from four key safety design perspectives:

1. Sealed & Reinforced Structure: First Line of Defense
TLS pressurized containers are built using weather-resistant steel and high-performance sealing components, including explosion-proof locks, cable glands, and dual-seal strips. Together, they form a highly airtight and pressure-resistant enclosure.

Even if internal equipment ignites or experiences a short-term deflagration, the structure effectively contains flames, sparks, and high-temperature gases, protecting the external environment.

All TLS pressurized containers are designed and manufactured in accordance with relevant explosion-proof standards (such as IEC 60079-13), meeting or exceeding industry-grade anti-explosion performance.

2. Pressurization System: Blocking External Gases and Monitoring Abnormalities
The core function of the pressurization system is to maintain internal pressure above ambient pressure, preventing flammable gases from entering and forming explosive mixtures with internal components.
TLS pressurization systems are equipped with:

• Pressure sensors and differential pressure alarms
• Combustible gas detection instruments
• Automated ventilation and power-off linkage

When anomalies occur (e.g. fire, pressure drop, gas concentration exceeding threshold), the system will immediately trigger alarms and initiate emergency measures like power shutdown or Close fire dampers—intervening before the situation escalates.

3. Explosion-Proof Electrical Selection: Controlling Hazards at the Source
Typical electrical components inside a TLS pressurized container include:

• Lithium battery systems
• DC/AC converters and inverters
• PLC or DCS control cabinets

Based on the risk level, TLS applies suitable explosion-proof strategies:

• Intrinsic safety (Ex i) for low-power control devices
• Flameproof (Ex d) or increased safety (Ex e) enclosures for high-power units
• Fireproof partitions or isolation chambers for lithium batteries and other sensitive modules

This “hazard-source control” approach greatly reduces fire or explosion risks at the component level.

4. On the explosion relief device: why we choose "prevention-oriented"

It is worth noting that: explosion relief device is not a standard feature of the positive pressure explosion-proof box (TLS is generally not equipped), in the structure of the double security of airtight and positive pressure system, the risk of flame or spark leakage to the outside has been effectively controlled.Avoiding the reactive approach of "after-the-fact reliance".

For extreme applications, such as high-capacity battery testing, high-pressure chemical reaction experiments, etc., TLS can also be customised to incorporate additional safety modules, such as directional exhaust systems or automatic fire extinguishers, to cope with the specific extreme conditions, if the customer requires a very high level of individual protection.However, this is not a standard feature.

5.Conclusion: A Systematic and Reliable Line of Safety Defense
Facing the complex risks of flammable and explosive environments, TLS’s pressurized explosion-proof containers are designed with a system-level safety philosophy—combining sealed structure, intelligent pressure control, electrical explosion protection, and optional emergency systems to deliver safe, reliable, and sustainable containerized environments.

At TLS, containers are not just equipment enclosures—they are your first line of safety.

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

In hazardous environments, extreme climates, or industrial settings with stringent air quality requirements, specialized containers must maintain a positive pressure environment to ensure personnel safety, stable equipment operation, and prevent the ingress of external pollutants. This article delves into the types of specialized containers that require positive pressure environments, their importance, and their applications.
 
What is a Positive Pressure Environment?
 
A positive pressure environment refers to a condition where the internal pressure of a container is higher than the external ambient pressure. This is achieved through continuous air supply , which prevent harmful gases, dust, or moisture from entering the container.pressurized systems typically include pressure control systems, gas monitors, and explosion-proof certifications (such as ATEX, IECEx, CNEX) to meet industrial and safety standards.
 
Specialized Containers Requiring Positive Pressure Environments and Their Applications
 
1. Explosion-proof Positive Pressure Container
 
Explosion-proof positive pressure containers are used in oil and gas drilling platforms (Zone 1 & Zone 2), chemical plants, refineries, LNG stations, and other industrial sites with flammable or explosive gases. The positive pressure environment prevents the entry of combustible and toxic gases such as methane (CH₄) and hydrogen sulfide (H₂S), reducing the risk of explosions and poisoning. Additionally, it ensures compliance with explosion-proof certification standards, enabling safe operation of equipment and personnel in hazardous environments.
 
2. Motor Control Center Room (MCC Shelter)
 
MCC shelters are widely used in oil and gas drilling platforms, chemical plants, mining operations, power plants, and offshore wind farms. The positive pressure environment prevents the ingress of flammable gases, reducing the risk of fire or explosion caused by electrical equipment. It also protects control devices such as PLCs, frequency converters, and switchboards from damage caused by moisture, and corrosive gases, while safeguarding personnel health by preventing exposure to toxic gases.
 
3. MWD/LWD Cabin (Measurement While Drilling/Logging While Drilling Cabin)
 
MWD/LWD cabins are primarily used in oil and gas drilling operations, both onshore and offshore, for measurement and logging while drilling. The positive pressure environment prevents harmful gases such as hydrogen sulfide (H₂S) and methane from entering the cabin during drilling, ensuring operational safety. It also maintains a clean and dry air environment for electronic measurement devices, computers, and remote monitoring systems, ensuring their stable operation.
 
4. MUD Logging Cabin
 
MUD logging cabins are used in oil and gas logging operations, formation monitoring, and drilling data analysis. The positive pressure environment prevents combustible gases released by drilling mud from entering the cabin, reducing the risk of explosions or poisoning. It also maintains constant air pressure and clean air, improving the accuracy of instrument analysis and protecting the health of operators.
 
5. Lab Container
 
Lab containers are used in petrochemical laboratories, gas analysis, environmental monitoring, and laboratories on offshore drilling platforms and refineries. The positive pressure environment prevents external pollutants or harmful gases from affecting experimental results and protects high-precision instruments from damage caused by moisture, and corrosive gases.
 
6. Application of Positive Pressure in Accommodation Modules
 
If accommodation modules are located on offshore drilling platforms, hazardous chemical plants, or extreme environments (such as polar regions, deserts, or high-humidity areas), they also require positive pressure systems. The positive pressure environment prevents the intrusion of toxic or harmful gases, ensuring the safety of occupants, while providing a constant supply of fresh air to maintain a comfortable living environment.
 
Conclusion
 
The application of positive pressure environments in specialized containers is an indispensable safety measure in modern industrial and energy sectors. Whether it is explosion-proof positive pressure containers, MCC shelters, MWD/LWD cabins, MUD logging cabins, lab containers, or accommodation modules, positive pressure systems play a critical role. They not only prevent the intrusion of harmful gases and pollutants but also ensure the safety of equipment and personnel, providing a stable and efficient working environment. In hazardous environments and extreme climates, Pressurized Containers have become a key technological solution for ensuring industrial production and personnel safety.
