Hazardous Area Zone 1 & Zone 2 Explosion Proof Pressurized Cabin

IP rating is the abbreviation of Ingress Protection (protection level). It consists of two numbers and is used to indicate the protection level of the electrical equipment casing against the intrusion of foreign objects.

1.Explosion-proof grade
The explosion-proof grade is used to indicate the risk level of the explosive environment that the equipment may encounter during use at its installation location. Usually, the explosion-proof grade consists of the word "Ex" and two numbers. The first number indicates the adaptability of the equipment to the environment, and the second number indicates the explosion-proof ability of the equipment.

ATEX is the abbreviation of the French "ATmosphères EXplosibles". It is an explosion-proof directive of the EU CE mandatory certification. The directive applies to a particularly large range of equipment, generally including fixed offshore platforms, petrochemical plants, flour mills and other equipment suitable for places where there may be potential explosive environments.

1. High demand for safety guarantee: In many industrial fields, such as petroleum, chemical, and coal mining, there are flammable and explosive environments. The demand for explosion-proof electrical equipment is the key to ensuring safe production. Therefore, the market demand is relatively stable and continuous.

Explosion-proof fans and ordinary fans are two different types of equipment used to provide air flow and ventilation. However, there are significant differences between them in terms of working principles, materials and design. The differences between explosion-proof fans and ordinary fans, as well as the advantages of explosion-proof fans in terms of safety and environmental protection as following:

ATEX certification is the explosion-proof directive 2014/34/EU formulated by the EU CE certification. The goal of ATEX is to ensure the free flow of explosion-proof products within the EU by providing a unified compliance procedure accepted by all EU countries, thereby eliminating the need for different national standards. The directive eliminates trade barriers by defining essential health and safety requirements (EHSR) for Ex equipment.

1. Emerging technological advantages: With the development of the industry, explosion-proof electrical products with high technological content and high added value will gradually shake off the influence of low-price competition. The price will generally rise steadily, and enterprises with independent R & D capabilities will be more competitive in the market.

Pressurized explosion-proof control cabinet refers to the principle that the pressure of protective gas in the pressurized closed space is higher than the external atmospheric pressure, which can effectively prevent the external explosive gas from entering the closed space or dilute the explosive gas concentration released in the closed space to below the explosion index to complete its application.

1.Shell Material:
It is usually formed by steel plate welding, cast aluminum alloy or 304 stainless steel die-casting, and the surface is subjected to high-voltage electrostatic spray coating. Generally, a composite structure combining explosion-proof shell and increased safety shell is adopted.

1. Principle of Flameproof Type (Ex d):
The shell of the flameproof explosion-proof control box can withstand the explosion pressure generated by the explosion of the internal explosive mixture and can prevent the explosion flame from spreading to the explosive mixture around the shell. The flameproof joint surface between the components of the shell has sufficient parameters such as clearance, length, and surface roughness, so that the high-temperature and high-pressure flame generated by the explosion is rapidly cooled and extinguished when passing through the flameproof gap, so as to achieve the purpose of isolating the explosion.
