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

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.
