The transfer window is an auxiliary equipment for clean rooms, mainly used for the transfer of small items between clean areas and between clean areas, as well as between clean and non clean areas, in order to reduce the number of open doors in the clean room and minimize pollution to the clean room. The transfer window is made of stainless steel plate, which is flat and smooth. The two doors are interlocked to effectively prevent cross contamination, equipped with electronic or mechanical interlocking devices, and equipped with ultraviolet sterilization lamps.
brief introduction
The transfer window, as an auxiliary equipment in the clean room, is mainly used for the transfer of small items between the clean area and the clean area, as well as between the non clean area and the clean area, in order to reduce the number of door openings in the clean room and minimize pollution in the clean area. Transfer windows are widely used in micro technology, biological laboratories, pharmaceutical factories, hospitals, food processing industries, LCD, electronic factories, and other places that require air purification.
classification
Transfer windows are divided into three categories:
1. Electronic chain transmission window
2. Mechanical interlocking transmission window
3. Self-cleaning transfer window
The transfer window can be divided into wind drenched transfer window, ordinary transfer window, and laminar flow transfer window according to its working principle. Various models of transfer windows can be made according to actual requirements.
Optional accessories: Interphone, sterilization light and other related functional accessories.
characteristic
1. The working surface of the short distance transmission window is made of stainless steel plate, which is flat, smooth, and wear-resistant
2. The working surface of the long-distance transmission window adopts a non powered roller, making it easy and convenient to transfer items
3. Both sides of the doors are equipped with mechanical interlocking or electronic interlocking, and electronic locking devices to ensure that both sides of the doors cannot be opened at the same time. 4. We can customize various non-standard sizes and floor mounted transfer windows according to customer needs.
5. The wind speed at the air outlet of the air nozzle can reach over 20 seconds.
6. Adopting a high-efficiency filter with a partition, the filtration efficiency is 99.99%, ensuring the purification level.
7. Using EVA sealing material, with high sealing performance.
8. Pairable calling intercom
operational principle
1. Mechanical interlocking device: Internal interlocking is achieved through mechanical means. When one door is opened, the other door cannot be opened and must be closed before opening the other door.
2. Electronic interlocking device: Internal interlocking is achieved by using integrated circuits, electromagnetic locks, control panels, indicator lights, etc. When one door is opened, the opening indicator light of the other door does not light up, indicating that the door cannot be opened, and the electromagnetic lock operates to achieve interlocking. When the door is closed, the electromagnetic lock of the other door starts to work, and the indicator light will light up, indicating that the other door can be opened.
Usage method
The transfer window should be managed according to the cleanliness level of the higher level clean area connected to it, such as the transfer window connecting the spray code room and the filling room should be managed according to the requirements of the filling room. After work, the operator in the clean area is responsible for wiping the internal surfaces of the transfer window clean and turning on the UV sterilization lamp for 30 minutes.
1. Materials entering and exiting the clean area must be strictly separated from the pedestrian passage and accessed through a dedicated passage for materials in the production workshop.
When the 2 materials enter, the process leader of the preparation team organizes personnel to unpack or clean the appearance of the raw and auxiliary materials, and then sends them to the temporary storage room of the workshop raw and auxiliary materials through the transfer window; The inner packaging materials are removed from the outer temporary storage room and sent to the inner packaging room through the transfer window. Workshop comprehensive staff.
