The most critical feature of this cabinet is its Ex d IIB T4 Gb explosion-proof rating, which means it can be used in Zone 1 and Zone 2 explosive atmospheres with flammable gases and vapors. The explosion-proof sealing structure uses flameproof joints with a minimum gap of 0.5mm to contain any internal explosions and prevent flames from escaping. The heat pipe cooling system transfers heat from inside the cabinet to the external environment without using electrical fans, eliminating the risk of spark generation. The 304 stainless steel construction is resistant to corrosion from acids, alkalis, and saltwater, making it suitable for coastal oil refineries and chemical processing plants. Additionally, the cabinet is equipped with explosion-proof emergency lighting that automatically activates in case of power outages, ensuring safe operation in hazardous environments. All electrical components are certified to ATEX and IECEx standards, and the cabinet undergoes rigorous explosion-proof testing before leaving the factory.
The cabinet has an overall dimension of 1800mm (height) × 600mm (width) × 600mm (depth), with a 36U rack capacity to fit standard control equipment and power distribution units. The main body is made of 3mm-thick 304 stainless steel, with flameproof joints machined to a precision of ±0.02mm to meet explosion-proof requirements. The heat pipe cooling system has a heat dissipation capacity of 2000W, maintaining internal temperatures below 40°C even in external environments up to 55°C. Cable entry points are equipped with brass explosion-proof glands that support cable diameters from 10mm to 25mm, ensuring a tight seal to prevent gas ingress. The explosion-proof emergency lighting has a brightness of 500 lumens and a battery life of 90 minutes, powered by a 12V DC rechargeable battery. The cabinet is mounted on an explosion-proof steel base with anchor bolts to ensure stability, and all internal wiring uses explosion-proof cable conduits. It is certified to ATEX, IECEx, and GB3836 standards, fully compliant with global hazardous location regulations.
This cabinet is essential for oil and gas refineries, where it protects power distribution units and control systems in areas with flammable hydrocarbon gases. It is also widely used in chemical plants, safeguarding instrumentation and control equipment in zones with explosive chemical vapors. In coal mining sites, it serves as a protective enclosure for underground power distribution systems and monitoring equipment, preventing ignitions from coal dust and methane gas. Additionally, it is applicable for paint manufacturing facilities, grain processing plants, and pharmaceutical factories where explosive dust or vapors are present. Its compliance with international explosion-proof standards makes it a reliable choice for any industry operating in hazardous environments, ensuring the safety of personnel and equipment.
