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:
