Let’s look at some of the functions and applications of the clean room thus:
· Microbial limitation: in occupied areas near aseptic operations, to minimize the introduction of contamination in the exclusion zone.
· Microbial exclusion: to prevent sterile materials contamination, as well as to protect surfaces and components in aseptic operations.
· Particle exclusion: often associated with microbial exclusion, it is also applied independently for materials washed before sterilization.
· Exclude cross-contamination: to prevent contamination of one material or product with another.
· Particle limitation: to reduce the particle load on elements before washing.
The clean room windows are typically designed with double safety glass forming a continuity with the panel.
To achieve the objectives of a cleanroom mentioned above are defined in the project processes and operations to be performed, setting the flowchart best suited, considering all aspects of functionality, maintenance, and control, and reflecting the conclusions in documents and plans to be approved by qualified personnel.
The first agreement will be to determine the raw materials and the flow of personnel logically, without causing any functional issues which may obstruct control operations and maintenance in a clean room. Therefore, we must design technical areas where maintenance and control personnel can access the clean rooms without interfering with the usual production operations. Here, the fire-rated vision panel is applied as it helps with accurate vision.
The clean room windows and ceilings are constructed with self-supporting sandwich panels assembled together by tongue and groove and with a completely smooth surface. Developed for use as a partition wall, or as an element, Trans dosed to a pre-existing construction.
Filtration is the heart of the Clean rooms. There are, however, numerous elements to take into consideration for the classification of the different types of rooms. Choosing the right filters both in the prefiltering stages and in the final filtering is the key to achieving the desired objective.
The use of high-efficiency terminal filters requires the installation of prefiltration and intermediate filtration stages that guarantee us for a long life of the terminal filters and, on the other, avoid stopping production with the replacement of terminal filters and the numerous tests necessary to verify that they meet the required requirements.
The efficiency in the retention of particles of the absolute filters is key to determine the quality of the air. The development and progress of particle counters and the need to know the effectiveness of fractional filters, according to the particle size difference, have led to new test methods, especially for the highest efficiency absolute filters. For example, test methods using laser counters.
Air treatment adjusted to the conditions and measurements of the Room creating an air sweep that helps the purification of the area.
The humidity and temperature are controlled through the centralized or distributed air conditioning systems to achieve good comfort, the number of renovations needed per hour and minimum consumption.
The most used systems are by means of heat pumps or exchangers with steam circulation, water (hot/cold) or direct expansion. Systems humidification or dehumidification.
