About offshore positive pressure container used in Zone1/Zone2
Positive pressurized containers can provide a safe environment for equipment and people in hazardous areas. The principle of a positive pressure blast-proof container is to achieve the technical requirements of blast-proofing through enclosure. A positive pressure ventilation system is the key.
It delivers fresh air from a safe area to the container through ducts that pure the air inside the container and maintain a slightly higher air pressure inside the container than outside. In this condition, no harmful and flammable gas can enter the enclosure.If 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. If the control conditions inside the container are still not required within the specified time, the non-explosive device will automatically cut off. Thus, the common equipment in the container fulfils the purpose of blast protection.

About CPFG（combined pressurization fire&gas system) of positive pressure container
CPFG is a complete suite of intelligent booster control systems, typically used in positive pressure containers, with gas detectors, smoke detectors, heat detectors, fire alarms, pressure switches, flow switches, booster fans, emergency stop & alarm mute switches, and other explosion protection equipment.
The CPFG is also connected to a power distribution board, which will be connected by non-explosive devices inside the container, such as sockets, fume hoods, computers, water heaters, etc.
When the power is turned on, the CPFG turns on the booster fan to purge the inside of the container to positive pressure. This prevents dangerous gases entering from outside. When the environment inside is safe, the DB (distribution board) will start up and the internal non-explosive electrical equipment can be used normally. The DB cannot be started if the environment inside the container is not secure.
During operation, if dangerous gases are detected in the container or the positive pressure cannot be maintained, the alarm system will sound an alarm and issue a warning. If the control conditions in the container are not met within the specified time, the non-explosive device is automatically turned off. Therefore, the general equipment in the container is suitable for blast protection purposes.

The ventilation part of the positive pressure explosion-proof container mainly includes the cooling and heating system of the fan for air supply and ventilation, indoor air conditioning, and heater. In the container, the air is supplied from a long distance by a centrifugal exhaust fan to finally achieve the purpose of indoor positive pressure.
Refrigeration/Heating: Choose split air conditioners for explosive gas atmospheres. The ambient temperature is -7°C~43°C, and 80% of the working conditions are widely used in hazardous environments such as oil exploration and refining, as well as offshore oil platforms. The internal unit can choose not to be explosion-proof, and foreigners must have the overall explosion-proof certification of the explosion-proof organization.
Air supply fan: The booster fan will choose a centrifugal explosion-proof fan. When the booster system is activated, the fan will always work, so the protective gas can continuously replace the original air in the room, so as to ensure the safety of the container. In order to monitor the air exchange rate, a flow sensor is installed at the air outlet.
As a new container product in recent years, the positive pressure explosion-proof container still needs to accumulate technical strength. It has great prospects in the future container market and because it is a high-level service container, its added value is very high

Land-based oil exploration and offshore platform oil exploration areas have the potential to produce explosive gases, and for areas where fires and explosions may occur are known as hazardous areas and are generally divided into three zones - Zone 0, Zone 1, and Zone 2.  Modern drilling and exploration sites require strict explosion-proof performance of the equipment on site, so TLS provides the perfect solution with positive pressure explosion-proof containers 
 
The principle of the positive pressure explosion-proof container is to achieve explosion-proof technical requirements through the container shell, so that all the regular non-explosion-proof machinery installed in the container achieve the purpose of explosion-proof.
 
The positive pressure ventilation system ​ is the key to making the container explosion-proof. When the total power supply is turned on, firstly the system automatically turns on the explosion-proof blast system. The explosion-proof centrifugal fan extracts fresh air from 30 meters outside the danger zone into the positive pressure container. The air in the positive pressure container is purged and a positive pressure of more than 50pa is established. The total power supply is automatically turned on when the control conditions are met, then the power supply can be turned on to control the power supply and turn on other electrical equipment in the positive pressure container.
 
In the process of turning on or in the operation of the equipment in the container, if the explosion-proof control system monitors the presence of dangerous gases in the container or fails to reach the corresponding positive pressure, the alarm system will alarm and warn, and if the control conditions in the container are still not met within the specified time, or if the alarm limits are reached directly, the non-explosion-proof control system in the container will be closed automatically, so as to achieve the purpose of explosion-proof.

Intelligent pressurized containers can provide a safe environment for equipment and people in hazardous areas. The principle of a positive pressure EX-proof cabin is to achieve the technical requirements of blast-proofing through enclosure. A positive pressure ventilation system is the key.
It delivers fresh air from a safe area to the container through ducts that pure the air inside the container and maintain a slightly higher air pressure inside the container than outside. In this condition, no harmful gas can enter the enclosure.
If 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. If the control conditions inside the container are still not required within the specified time, the non-explosive device will automatically cut off.
Thus, the common equipment in the container fulfils the purpose of blast protection.

​Motor control center (MCC) shelters consist of single or multiple electrical units, which are combined to meet larger application needs. These components allow engineers to control electric motors from a central location, such as a mechanical or electrical room.
MCCs are typically found in large commercial or industrial buildings and typically contain motor starters, circuit breakers, programmable controllers, metering devices, etc. MCCs may be used in any facility that operates a large number of electric motors.
