3. Suitable for Zone 20, Zone 21, and Zone 22 environments with combustible dust;
4. Suitable for environments with temperature groups T1-T6;
5. This product is suitable for use in factories such as petrochemicals, offshore drilling platforms, metallurgy, pharmaceuticals, light industry, textiles, brewing, paints, coatings, food, biotechnology, aerospace engineering, and military facilities;

Product Features
1. The outer shell of the explosion-proof positive pressure cabinet is welded with high-quality steel plates or stainless steel, and the surface is subjected to high-speed shot blasting and powder electrostatic spraying, resulting in a beautiful appearance;
2. The explosion-proof positive pressure cabinet is an improved explosion-proof product called "Ergong Explosion proof", which can install various ordinary detection instruments, analysis instruments, display instruments, transformers, soft starters, frequency converters, etc. according to user requirements PLC、 Various buttons, switches, microcomputer touch screens, and ordinary electrical components are not restricted for users to install electrical components;
3. The explosion-proof positive pressure cabinet adopts a diversified design, which can be selected from cabinet type (top and bottom form, left and right form), wall mounted type, piano table type, flat type, etc;
4. The explosion-proof positive pressure cabinet distribution cabinet consists of a cabinet body, a control system, a gas distribution system, an alarm system, and a power distribution system; Explosion proof components for the control system and user's power distribution system components installed in the positive pressure chamber (can also be customized as separate or online according to customer requirements);

5. The air intake method for the left and right cabinets of the explosion-proof positive pressure cabinet is ventilation type, which means uninterrupted continuous air supply. The working heat of the components installed in the positive pressure chamber can be carried away with the air path, which has a good heat dissipation effect.
6. The explosion-proof positive pressure cabinet is designed, manufactured, and inspected in accordance with GB3836.1-2000, GB3836.5-2004, and relevant standards.
Under the control of the automatic control system, the explosion-proof positive pressure cabinet is filled with protective gas, and the pressure inside the positive pressure chamber is higher than the pressure outside the positive pressure chamber, forming a safe small environment with slight positive pressure, thereby preventing flammable dangerous gases from entering the positive pressure chamber and ensuring the safe operation of ordinary instruments and electrical components inside.
7. The automatic control system of the explosion-proof positive pressure cabinet mainly completes functions such as ventilation, air supply, automatic alarm and exhaust for ultra-high pressure, undervoltage alarm, and low-voltage interlocking power-off. This positive pressure cabinet has a low-voltage interlocking function, which automatically cuts off the user's distribution power supply to the positive pressure chamber when the air pressure is below the specified value (50Pa). This further confirms the safety and practicality of the product;
8. Protective doors can be installed outside the explosion-proof positive pressure cabinet according to customer requirements, which can display the display or action of the internal control part;
9. All fasteners are made of corrosion-resistant 304 stainless steel material;
10. Wiring methods include steel pipes, cables, and explosion-proof hoses;
11. It can be customized according to user requirements;
