In high-risk industries such as oil & gas, chemical processing, and new energy, safety always comes first. To protect both personnel and equipment operating in potentially explosive or toxic environments, TLS has developed an Explosion-Proof Pressurized Container System, offering a secure and reliable workspace for Zone 1 and Zone 2 hazardous areas.
1. The Principle of Positive Pressure – Building a Shield of Air
At the heart of TLS’s safety design lies the positive pressure protection principle.
Clean air is continuously delivered into the container through a dedicated ventilation system, ensuring that the internal air pressure is always higher than the surrounding environment.
This pressure difference acts as an invisible barrier: any external air containing flammable or toxic gases cannot enter the container, effectively preventing explosion and poisoning risks.
A standard TLS pressurization system includes:
Even if gas leaks or explosive mixtures appear outside, the interior environment remains safe and breathable.
2. Built to International Standards
TLS pressurized containers are engineered and certified according to international standards such as IEC 60079-13 and DNV 2.7-1.
They are equipped with explosion-proof air conditioners, lighting, and electrical components, all tested and verified by third-party authorities.
These containers are designed for long-term operation in Zone 1 and Zone 2 areas, meeting the strict safety requirements of the global oil, gas, and chemical sectors.
3. Smart Airflow and Pressure Monitoring
Safety meets intelligence in TLS’s smart control system.
By automatically monitoring pressure, airflow, and gas concentration, the system maintains optimal working conditions without manual adjustment.
Key features include:
This smart system ensures continuous safety with minimal operator intervention.
4. Modular Design for Flexible Applications
TLS explosion-proof pressurized containers are modular and customizable, allowing them to serve as control rooms, laboratories, accommodation units, or multifunctional modules.
Their modular structure makes them easy to transport, stack, and install on site — whether on offshore platforms, drilling rigs, or chemical plants, they can be quickly deployed to provide a safe and comfortable workspace.
5. Customization and Full Lifecycle Support
TLS offers end-to-end service — from design and manufacturing to installation, commissioning, and after-sales support.
Each unit can be customized in size, fan configuration, electrical interface, and monitoring system to fit the specific needs of your project site.
Conclusion
The TLS Explosion-Proof Pressurized Container creates a secure working environment by maintaining positive internal pressure, ensuring that hazardous gases are kept out at all times.
With its robust safety design, international certifications, intelligent monitoring, and modular flexibility, TLS continues to deliver safe, reliable, and fully customizable solutions for hazardous area operations worldwide.

In high-risk laboratory environments—from volatile chemical synthesis to advanced biological research—safety often hinges on reagents and procedures. Yet, the single most fundamental safety measure is often overlooked: spatial isolation and air control.
This is precisely where an advanced solution like the TLS Negative Pressure Laboratory Container becomes indispensable. It’s not just a piece of equipment; it’s a dedicated, sealed environment that represents the most critical safety barrier your lab can deploy.
What is a Negative Pressure Containment Container?
A Negative Pressure Containment Container is a specialized, sealed chamber engineered for high-risk lab operations. Its defining feature is a precise pressure control system that maintains an internal air pressure lower than the surrounding room.
How Does Negative Pressure Work for Containment?
By design, this lower pressure creates an inward airflow. If any structural breach or seal failure occurs, the pressure differential ensures that air always flows into the container, effectively preventing hazardous gases, particles, or biological aerosols from escaping.
Key Difference: Unlike common positive pressure systems (which push contaminants out), a negative pressure system is designed explicitly to contain contamination. This containment-first philosophy requires more rigorous design standards in sealing, air handling, and pressure stability.
3 Reasons Your Lab Needs a Dedicated Negative Pressure System
Labs handling toxic, volatile, or infectious materials cannot rely on standard ventilation alone. Here’s why a dedicated Negative Pressure Containment Container is non-negotiable for critical procedures:
Key Design Features of the TLS Containment Container
The TLS design focuses on stability and reliability under pressure:
Where Are Negative Pressure Containers Used?
The robust containment and flexibility of the TLS containers make them ideal for:
Summary: Small Footprint, Uncompromised Safety
At first glance, the TLS negative pressure lab container may resemble an ordinary shipping container. But inside, its airtight structure, precise ventilation logic, and isolation design provide an essential safety shield for high-stakes research.
In a world where laboratory risks are often unpredictable and regulatory standards are constantly tightening, a structurally reliable and functionally stable Negative Pressure Containment Container is one of the most essential foundations of your safety infrastructure.

- Prevent Harmful Gas and Particle Dispersion
- Eliminate Airflow Blind Spots of Fume Hoods
- Ensure Mandated Regulatory Compliance
Key Design Features of the TLS Containment Container
The TLS design focuses on stability and reliability under pressure:
- Superior Structural Sealing: Built on a fully welded steel frame with multiple layers of industrial-grade sealing and locking systems.
- Precise Pressure Control: Equipped with variable frequency exhaust fans and highly accurate differential pressure sensors. This automated system actively maintains a stable internal pressure in the vital -20Pa to -50Pa range.
- Customizable and Modular: Available in common 20ft and 40ft container sizes. These units are pre-assembled for crane-lifting and easy relocation, making them ideal for rapid setup, building-to-building transfer, or temporary site operations.
- Others: Customization includes observation windows, power outlets, explosion-proof lighting, and corrosion-resistant countertops to match any operational need.
Where Are Negative Pressure Containers Used?
The robust containment and flexibility of the TLS containers make them ideal for:
- Volatile or toxic organic and chemical synthesis.
- High-risk pharmaceutical R&D procedures.
- Pre-treatment and inactivation of biological samples and viruses.
- Establishing emergency contamination control zones.
- Temporary or isolated storage of hazardous waste and biological specimens.
