| Purification engineering:Control products (such as silicon chips, etc.) contact with the air cleanliness and temperature and humidity, so that the product can be produced and manufactured in a good environmental space, the design and construction process of this environmental space can be called purification engineering. Industry Application:Purification engineering is a very broad application industry of basic supporting industries, in electronic information, semiconductor, optoelectronics, precision manufacturing, medicine and health, biological engineering, aerospace, automotive spraying and many other industries are applied, and according to the precision and dust-free requirements of the industry, the grade difference is also large. Advantages of purification engineering:A. The air treatment effect is good, because the air is treated in A centralized way, and the pollution degree is low in the process of air supply. Comparison of temperature and humidity control of air supply B. It is more suitable for those with centralized cold source or larger workshop C. The cold and heat sources of air conditioning can be shared with the common air conditioning system of the workshop or independent cold and heat sources: D. The maintenance frequency is low. The noise in the workshop is low |
