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.
