Jiede Electronic Technology Co., Ltd. teaches you to understand the explosion-proof of mining and the explosion-proof analysis of chemical industry zone

At present, the explosion-proof products on the market can be described as dazzling, but many users are not specializing in explosion-proof products. Faced with a variety of explosion-proof products, they often fall into the misunderstanding of use. One of the main misunderstandings of Zui is that mine explosion-proof products are used in chemical industry. Area? Or is the chemical zone used in the mining area with explosion-proof equipment?
Then, can the mine explosion-proof products and the explosion-proof products used in the chemical industry zone be universal? To answer the above questions, first understand the following explosion-proof knowledge:
1. In China and IEC countries, explosive substances are divided into three categories:
Class I: Mine Methane
Class II: Explosive gas mixture (including steam, mist)
Class III: Explosive dust and fiber
2. Explosion-proof electrical equipment is divided into two categories:
Class I coal mine underground electrical equipment
Class II electrical equipment used in locations other than mines
Among them, Class II equipment is divided into IIC, IIB, IIA according to the level of explosion-proof grade, among which the explosion-proof grade of IIC equipment is high, and it is also safe. The reason why the mining equipment is divided into Class I separately is mainly because the explosive gas under the mine is relatively single, mainly gas and dust; and the explosive gas of the plant equipment is various, and the explosive environment formed is also numerous, so the explosion-proof equipment The requirements are more stringent.
Whether in China or other countries in IEC, the first thing to consider when setting standards for explosion-proof products is the environment in which explosive gases are exposed. The environment in which explosive gases are exposed is different, and the degree of difficulty in explosions changes. The environmental difference between the underground mine and the chemical industry zone of the factory is very large. There are more potential environmental risk factors in the chemical industry zone of the factory. The explosive gas environment for the explosion-proof equipment manufactured is also very different. Therefore, the equipment for mining equipment and chemical industry zone cannot be used universally. . Some people will take it for granted: "Since all can be used under the mine, it can of course be used in the chemical industry, because the level of mining equipment is relatively high." This sentence is completely wrong and is based on a lack of professional understanding of explosion-proof knowledge. If it is necessary to classify the mining products and the products in the chemical industry zone, then the explosion-proof grade of the products used in the chemical zone is high. (In fact, chemical and coal mines are two completely different environments, so there is no need to compare them)
In order to increase the scope of application environment, G&D Electronic Technology R&D Center has successfully developed products that meet both Class I and Class II explosion-proof requirements. See the product introduction for details.

KC/KWB series Industrial Chiller is mainly applied in Plastic & Rubber industry; it can accurately control the molding temperature and shorten the molding cycle, increase the product quality and improve the production efficiency. They are also widely used in Metal working, Mechanical & Engineering, Chemical & Pharmaceutical, Food & Beverage, Laser, Electronics industry, Textile, Electroplate, Semi-conductor testing, Water jet, Vacuum coating, Construction and Military.

Design features

¨ Adopted world famous brand compressors and high efficiency condenser and evaporator, ensure high cooling efficiency, low energy consumption, low noise and long service life.

¨ Chilled water temperature range 5℃ to 35℃.

¨ R22 charged, CFC free type R407C, R410A, R404A, R134A for option, high cooling efficiency.

¨ Over sized evaporator and condenser ensure the chiller unit running under 45C high ambient temperature.
