With the rapid development of the social economy .

Especially the scientific experiments and high-tech production processes,

Such as microelectronics, bioengineering, and precision machine processing,

they will raise higher requirements for the precision, miniaturization, high purity, high quality and high reliability.

Control the temperature, humidity and cleanliness of the atmosphere that products (such as silicon chips) are exposed to, so that the products can be produced and manufactured in a good environmental space. Such as cleanroom or clean workshop

The design and construction process of this cleanroom can be called purification engineering.

One of the most notable features is the ability to maintain the cleanliness, temperature, humidity, and pressure required to maintain the original settings, regardless of changes in external air conditions.

The clean workshop production environment is not only related to the health and comfort of the production activities of the employees, but also related to the production efficiency, product quality, and even the important issues of the production process.
