In chemical, oil & gas, and fine chemical industries, positive pressure ventilation systems are widely used in pressurized containers, explosion-proof containers, and functional containers. Their main purpose is to maintain a constant positive pressure inside the container, preventing the entry of flammable gases, dust, or corrosive air. This greatly reduces explosion risks and provides a safe, stable working environment for electrical and control equipment.
A well-designed system is not only about safety—it also extends equipment lifetime and improves system reliability. Below are the key points to consider in design:
1. Fan and Airflow Design
2. Air Ducts and Flow Organization
3. Pressure Monitoring and Control
4. Cable and Interface Sealing
5. Safety and Redundancy
Conclusion
Designing a positive pressure ventilation system is not only about fan selection. It is a system-level project involving airflow calculation, duct layout, filtration, monitoring, and intelligent control. A reliable design provides safe protection in hazardous environments and ensures stable operation of electrical and control equipment.

A well-designed system is not only about safety—it also extends equipment lifetime and improves system reliability. Below are the key points to consider in design:
1. Fan and Airflow Design
- Airflow calculation: The airflow should be designed based on the container volume, heat load of the equipment, and protection level, ensuring a stable positive pressure difference.
- Redundancy: In critical applications, dual fans (one standby or parallel use) are often applied to keep the system running even if one fan fails.
- Variable frequency control: By using frequency converters, fan speed can be adjusted dynamically according to pressure feedback.
2. Air Ducts and Flow Organization
- Flow path: Air circulation should cover the whole container, avoiding short-circuit loops.
- Avoiding dead zones: Areas with high heat load should receive sufficient airflow to prevent hot spots or dust accumulation.
- Flow resistance: Duct cross-sections should be designed to minimize bends and resistance, ensuring stable pressure.
3. Pressure Monitoring and Control
- Sensor placement: Pressure sensors should be installed in key areas to monitor the pressure difference inside and outside the enclosure in real time.
- Automatic control:Adjust the fan speed through the frequency converter to change the air supply, through the speed adjustment to adapt to different pressure requirements, so as to achieve frequency control according to the Automatic control.
4. Cable and Interface Sealing
- Cable entries: Use certified explosion-proof cable glands to prevent leaks.
- Interface sealing: All inspection doors, windows, and pipe connections must be properly sealed.
5. Safety and Redundancy
- Dual power supply: For critical operations, fans can be connected to dual power sources or UPS to avoid failure during power cuts.
- Emergency exhaust: In some cases, an emergency exhaust function can be added to quickly replace the internal air.
Conclusion
Designing a positive pressure ventilation system is not only about fan selection. It is a system-level project involving airflow calculation, duct layout, filtration, monitoring, and intelligent control. A reliable design provides safe protection in hazardous environments and ensures stable operation of electrical and control equipment.

In petrochemical plants, on oil & gas platforms, and within hazardous chemical zones, frontline technicians face extreme conditions every day. Volatile gases, airborne dust, heat, and confined spaces are the norm. Yet, when critical tasks like electrical maintenance, instrument calibration, or temporary testing are required, a safe and clean workspace is often hard to find.
At TLS, we believe safety shouldn't be a luxury. That's why we designed the Positive Pressure Workspace. It’s more than just a container; it's a dedicated, controlled work zone engineered to keep your personnel and sensitive equipment safe, even in the most explosive atmospheres.

One of the most innovative features of TLS Offshore EX-Proof Containers is their sophisticated pressurization system. In a potentially explosive atmosphere, the goal is to prevent any spark or heat source from coming into contact with flammable substances.
Here's how the pressurization system achieves this:
- Creates a "Safe Zone": The system maintains a higher pressure inside the container than the surrounding environment. This constant overpressure effectively pushes hazardous gases or dust away, preventing them from entering the container.
- Constant Monitoring: Built-in sensors continuously monitor the internal pressure. If a drop or fluctuation is detected, the system immediately takes action, either by automatically adjusting the pressure or alerting operators.
- Protects Sensitive Equipment: By keeping the internal atmosphere clean and controlled, the system safeguards delicate electronics and instrumentation from contamination and potential ignition risks.
- Extreme Durability: The pressurization system is designed to function flawlessly even in the harshest offshore conditions, ensuring uninterrupted safety and operational continuity.
This technology isn't just a feature; it's a dynamic safety barrier that actively protects your assets and personnel.
