Touchscreen Clean Pass Box Controller for Cleanroom

● Features
Fan Speed ​​Adjustment: Users can adjust the fan speed according to their needs. Generally, this is done by pressing the setting button, entering a password to enter the setting mode, and then adjusting the fan speed in the corresponding settings interface. After adjustment, the data is saved, and the fan speed will be changed.
Intelligent Control: Some controllers support multiple sterilization modes, such as UV circulation sterilization and ozone sterilization. They also allow setting the number of air changes to ensure cleanliness within the transfer window. Additionally, some controllers have scheduled start/stop functions, allowing users to pre-set the equipment's operating time.
Data Display and Recording: Typically equipped with a touchscreen, it can intuitively display fan operating status, current fan speed, sterilization time, pressure difference, and other information. Some controllers also have a recording function, storing time parameters and completion status data during the sterilization process. Records can be exported to Excel format via USB flash drive for easy data traceability and management.
Security Protection: A password protection function is provided. Modifying sterilization parameters and general settings requires a password to prevent accidental operation. Additionally, some controllers have a door status detection function, ensuring that the fan starts and sterilization operation is only permitted when the door is closed to avoid cross-contamination.
Security Protection: Password protection is provided. Interlock Function: The two doors of the pass-through window typically have an interlock function. The controller can implement this function through devices such as electromagnetic locks, ensuring that the two doors cannot open simultaneously, effectively preventing cross-contamination.

●Working Principle: The touchscreen cleanroom pass-through window controller connects to components such as the fan, electromagnetic lock, and germicidal lamp of the pass-through window to control these components. When the user operates on the touchscreen, such as adjusting the fan speed, the controller sends corresponding electrical signals to the fan speed control device to change the fan speed. During sterilization, the controller controls the power supply to the germicidal lamp to achieve the sterilization function. Simultaneously, the interlock function of the doors is achieved through the control of the electromagnetic lock.

●Application Scenarios: Primarily used in places with high cleanliness requirements, such as GMP pharmaceutical workshops, biological laboratories, and electronic cleanrooms. In these places, items need to be transferred through cleanroom pass-through windows to prevent external contaminants from entering the clean area. The adjustable speed controller can adjust the fan speed according to different item transfer requirements and cleanliness standards to ensure a clean environment within the pass-through window.
