In environments such as offshore oil platforms, chemical processing plants, floating vessels, floating production storage and offloading (FPSO), most of the electrical and instrumentation facilities inside movable offices, container houses, etc. cannot satisfy the explosion-proof requirements of hazardous areas, the positive pressure mode can block the dangerous flammable gas out of the container, so as to achieve the overall explosion-proof function.
 
The principle of positive pressure explosion-proof container is to transport "clean and safe" air from a distance into the container through the air duct, "wash" the air in the container and maintain the pressure difference in the container, so as to ensure that the non-explosion-proof electrical equipment in the container is in the Safe area"to achieve the purpose of explosion-proof.

The positive pressure container provided by TLS meets DNV2.7-1, IEC60079-13:2017, and A60 fire rating, and can be used in ZONE2| ZONE1 area.
The built-in CPFG control system integrates PLC control system with man-machine interface and peripheral equipment. 
The Positive pressure explosion protection and fire control system mainly includes the following main functions:

• Monitoring and control of positive pressure explosion-proof system;
• Detection and monitoring of fire | flammable gas | toxic gas | sound and light alarm;
• Real-time monitoring display system alarm and fault status, and keeps historical records, and provides system alarm and fault signal to the remote central control system.
• The system automatically controls the shutdown of the output safety power supply | emergency shutdown | accepts remote shutdown control and other functions.

The operation modes of the control system are: positive pressure operation mode, bypass operation mode and manual emergency output power supply selection operation mode. Different operation modes can be easily selected according to the needs of the use site to achieve the purpose of safe and reliable operation of the system, convenient system maintenance and fast power supply.

Modules are strictly regulated in all operating environments involving offshore drilling, MWD or LWD. In ZONE 1 and ZONE 2, select different modules for different purposes.
Our portable modules are manufactured according to the International Maritime Organization safety of Life at Sea (SOLAS). Our design and manufacturing processes, including design and inspection, are certified by other third party classification societies

Many portable accommodation and industrial modules are designed for use in zone 1 or zone 2 areas. The two areas are classified as follows:
Zone 1 refers to "the combustible concentration of flammable gases or vapors that may be present under normal operating conditions".
Zone 2 refers to "an environment where such flammable concentrations are unlikely under normal conditions, but if they do occur, they occur only for a short time".

We have extensive experience and knowledge in providing safe and highly customized solutions to our customers in the offshore drilling industry. Our modules are available in a variety of configurations and sizes to meet the needs of various customer platforms, including weight limits and space limitations.

Make a preliminary judgment based on the following:
Do your containers need to be placed in hazardous areas (ZONE1, ZONE 2)?

• Yes, containers need to be placed in hazardous areas.
• You need an explosion-proof container.

a) If the equipment in the container is explosion-proof, you can choose a container with explosion-proof and A60 fireproof function only
b) If the equipment in the container is non-explosion-proof, you need to choose an A60 fireproof and explosion-proof positively pressurized container (the air supply volume is greater than the exhaust volume. The indoor air is in a positive pressure state. Combined with the air conditioning unit, the cleanliness of the air sent into the container can be guaranteed.)

• No, but the inside of the container is a danger zone.
• You need a negatively pressurized container with explosion-proof standards

the air supply volume is less than the exhaust air volume, and the main cabin is in a negative pressure state. The surrounding air flows into the space and is discharged through the exhaust port for unified treatment.

• No, both inside and outside the container are safe areas
• You can choose a non-explosion proof container.

You can request whether the container has fire protection requirements according to your own needs. In general, the container can meet the A60 fire protection standard. At this time, the container is equipped with the corresponding fire damper (when a fire occurs, the fire damper can be automatically closed to cut off the spread of the fire through the ventilation duct, suitable for ships, offshore platforms and underground Engineering and other humid environments)​

This is a positive pressure explosion-proof, fire grade A60 laboratory container, which can be used from -25 ℃ to +50℃, with good sealing, rain resistance, sand resistance, suitable for land oil exploration and offshore oil exploration in hazardous areas and desert areas. The design and construction meet the IEC60079-13 2010 specification, DNV2.7-1 and SOLAS 2009. Explosion-proof appliances meet the CNEX or ATEX explosion-proof standards.

The positive pressure test container is integrated with CPFG control cabinet, positive pressure air path system, explosion-proof centrifugal air unit, safe power supply system, fire alarm system, lighting system, alarm system, explosion-proof air conditioner, air valve control system and explosion-proof isolation switch box.

In order to meet the various conditions for the products to be used in Petrobras, TLS insists on strictly controlling the quality of the products in every step, from preprocessing of sheet and section steel to welding and assembly, from painting and decoration to debugging and installation, from label and decal to cleaning and packing. In addition to professional certification certificates, professional detection methods, real and convincing data and several measured operation results are the quality assurance that TLS believes should be provided to customers.

CPFG is divided into three working modes: manual mode, bypass mode and automatic mode. Turn the mode selector switch to the corresponding mode, at the same time, HMI face change will switch to the corresponding mode. The operation instructions of each mode are as follows:
 
Manual mode: only for emergency use, only the HMI "STOP" button/ESD signal/Cut-off signal can stop the output of safety power supply.
Bypass mode: Only can be used in safe area, make sure no dangerous gas and fire alarm start the safety power supply.
Auto mode: Can be used for normal use in dangerous area.

The pressurised container | MUD logging cabin | ATEX container | Zone 2 container | MCC shelter |Lab container provided by TLS Offshore container is equipped with explosion-proof temperature sensor and smoke detector.
When the temperature is too high and the smoke concentration is large, the fire alarm will be triggered.
