Design and engineering of cleanroom systems

Conceptclean room systemsoften thought of as a collection of filters and vacuum chambers. Many people believe that it is enough to buy high-quality filters and everything is ready. This is, of course, a simplification. The real challenge is a complex approach that requires a deep understanding of the process, cleanliness requirements and strict engineering standards. In my practice, most problems arise not due to a lack of equipment, but due to incorrect design and implementation.

What is truly clean air?

Determining air purity in a clean room is not a trivial task. People often talk about the level of particles of a certain size (for example, ISO class), but this is only one of the parameters. Gas concentrations, humidity, temperature, electrostatic charge are also important - all of this affects the technological process. For example, in semiconductor manufacturing, even minimal amounts of dust can lead to serious defects. Thereforedesign and engineering of clean room systemsmust take into account all these factors and correspond to the specifics of a particular production.

Take for example our experience with ?Tianjin Tongchang Junqi Cleaning Equipment Co.,Ltd? (https://www.tcfilter-group.ru). We often encounter a situation where customers order high-precision filters, but forget about vacuuming and degassing the premises. This is a serious miscalculation, because even the best filters will not be able to work effectively in an environment with a high concentration of gases and microparticles.

ISO classes: not a panacea

ISO classification is certainly important, but you shouldn’t focus only on it. Each class implies a certain level of contamination, but does not guarantee absolute cleanliness. In addition, ISO classes are determined in static conditions, and in real production areas there is constant movement of air, which can affect the level of pollution. It is important to consider dynamic parameters such as air speed, flow direction and the efficiency of ventilation systems.

For example, when designingclean room systemsfor pharmaceuticals, it is necessary to take into account the requirements of GMP (Good Manufacturing Practice). GMP involves not only maintaining cleanliness standards, but also monitoring all stages of production, including air, water and personnel. This requires a more complex and comprehensive approach to design and implementation than simply installing filters.

Main design stages

Design Processclean room systemsconsists of several main stages: analysis of the technological process, determination of cleanliness requirements, development of the system concept, detailed design and installation, commissioning and commissioning. At each stage it is important to take into account the specifics of production and customer requirements.

I pay special attention to the analysis stage of the technological process. It is not enough to simply know what substances are produced on premises; you need to understand all stages of production, including input and output materials, technologies and equipment used. This will help identify sources of pollution and choose the best air purification methods.

Vacuuming and degassing: the key to success

As I already mentioned, vacuuming and degassing rooms are critical steps in the creation processclean room systems. Vacuuming allows you to remove all contaminants from the room, and degassing allows you to remove gases and odors. These procedures must be carried out before starting up the equipment and repeated periodically during operation.

In our practice, we often encounter cases where clients neglect evacuation and degassing, which leads to serious problems with product quality. Sometimes it is necessary to stop production and re-clean the premises, which entails significant financial losses.

Selection of equipment: balance of price and quality

Equipment selection is another important design stage. You should not skimp on the quality of filters, fans and other equipment. This can lead to reduced system efficiency and increased maintenance costs. It is important to choose equipment that meets cleanliness requirements, is reliable and durable.

For example, when choosing HEPA filters, you should pay attention to their efficiency, throughput and service life. Some manufacturers offer filters with different types of fillers that can effectively remove various types of contaminants. It is important to select filters that are suitable for a specific process.

Real cases and lessons

We were working on a projectclean room systemsfor a chip development company. The main problem was the high concentration of dust and microparticles in the air. We have developed a comprehensive air purification system, including several stages of filtration, vacuuming and degassing of rooms. As a result, it was possible to reduce the level of contamination to the required level and ensure stable operation of the equipment.

However, not all projects end successfully. For example, one of our clients encountered problems with uneven air distribution in the room. This led to local contamination and reduced efficiency of the treatment system. We analyzed the ventilation system and made changes to the design, which allowed us to solve this problem.

Continuous Monitoring: The Key to Consistent Cleanliness

After enteringclean room systemsIn operation, it is necessary to continuously monitor air parameters such as pollution levels, temperature, humidity and air speed. This will allow you to promptly identify and fix problems, as well as maintain the system in optimal condition.

We recommend using modern monitoring systems that allow you to automatically collect and analyze data. This data can be used to optimize system performance and prevent problems from occurring. It is important not only to conduct regular checks, but also to analyze the data and draw conclusions about the effectiveness of the system.

Conclusion

Design and engineering of cleanroom systems– this is a complex and responsible task that requires deep knowledge and experience. Don't take it as a routine job. It is important to approach each project individually, taking into account the specifics of production and customer requirements. Only in this case can you create an effective and reliable system that will ensure stable operation of the equipment and high quality products.
