Zone 1 and Zone 2 refer to dangerous areas where explosive environments may exist or may occur during normal operation. Personnel working in these areas are threatened with life safety, and equipment used in these areas must be ex-proof to ensure safe use in potential explosive environments. However, the cost of ex-proof electrical equipment is high, and common general electrical equipment cannot meet the ex-proof requirements, such as monitors, printers, etc.
TLS can provide a positive pressure container, whose principle is to meet the ex-proof technical requirements by creating a positive pressure environment. The container is divided into a gas lock area and a main room. The gas lock area is set between the sealed outer door and the main room. There is an air inlet on one side of the container's corner, and an air outlet on the diagonal side of the inlet's corner. An ex-proof fan, a gas concentration detector, and an air flow detector are installed at the air inlet. And both the air inlet and outlet have wind valves and fire valves.
The advantages of the positive pressure containers,
