​Positive pressure containers are a critical component in various industries, including the oil and gas industry, where maintaining a sterile environment and preventing contamination is essential for safe and efficient operations. These containers utilize a specialized mechanism known as an air-lock compartment to ensure that the air inside remains under positive pressure.
 
An air-lock compartment is a small chamber located between the outside environment and the positive pressure container. This chamber features two airtight doors that prevent air from passing through when they are closed. The first door faces the external environment, while the second door faces the positive pressure container. The air-lock compartment's purpose is to enable people and objects to enter and exit the positive pressure container without compromising the sterile environment inside.
 
The process of entering the air-lock compartment begins by closing the first door. The chamber is then pressurized to match the positive pressure inside the container, preventing any air from the outside environment from entering the container. Once the air-lock compartment is pressurized, the second door facing the container can be opened, allowing a person or object to enter. Upon entry, the second door is closed, and the air-lock compartment is depressurized, removing any contaminants that may have entered the chamber.
 
In addition to providing a safe and sterile entry and exit point for people and objects, the air-lock compartment also serves as a means of removing objects and waste from the positive pressure container without contaminating the outside environment. When an object or waste is removed from the container, it is placed inside the air-lock compartment, and the second door is closed. The compartment is then pressurized, and the first door is opened, allowing the object or waste to be removed from the air-lock compartment and into the external environment.
 
In the oil and gas industry, positive pressure containers with air-lock compartments are essential for safe and efficient operations. They are used to maintain a sterile environment when drilling or performing other operations that require strict contamination control measures. Additionally, these containers are used to store hazardous materials and waste safely, reducing the risk of environmental contamination.
 
In conclusion, air-lock compartments are a critical component of positive pressure containers, enabling safe and sterile entry and exit points for people and objects while maintaining a contamination-free environment. In the oil and gas industry, these containers play a crucial role in ensuring safe and efficient operations, minimizing the risk of environmental contamination and protecting workers from hazardous materials.

Intelligent pressurized containers are indeed an effective way to provide a safe environment for equipment and people in hazardous areas. By maintaining a positive pressure inside the container, the risk of harmful gas or explosive substances entering the enclosure is greatly reduced, and the equipment and people inside the container are protected from potential explosions.
 
The positive pressure ventilation system is the key to ensuring the safety of the container. By delivering fresh air from a safe area through ducts, the system purges the air inside the container and maintains a slightly higher air pressure inside the container than outside. This pressure difference prevents hazardous gases or other harmful substances from entering the container.
 
In the event that the blast control system detects the presence of hazardous gases in the enclosure or fails to maintain positive pressure, the alarm system will sound an alarm and issue a warning. This warning gives the people inside the container time to take appropriate measures to ensure their safety. If the control conditions inside the container are still not met within the specified time, the non-explosive device will automatically cut off, providing an additional layer of protection.
 
All pressurized containers from TLS are designed, manufactured and certified to the latest DNV 2.7-1, EN 12079 offshore container standards, ATEX, IEC 60079-13 and/or SOLAS standards.This ensures that the containers meet the highest industry standards .
