VHP gasification hydrogen peroxide sterilization transfer window, also known as VHP sterilization transfer window, VHP type room temperature sterilization transfer window, transfer cabinet, and transfer box.

VHP Gasification Hydrogen Peroxide Sterilization Transfer Window VHP Sterilization Transfer Window Disinfection and Sterilization Transfer Window Product Introduction and Application: VHP Hydrogen Peroxide Transfer Window is a sterilization equipment that can provide biological cleaning on the surface of objects when transferring them between different functions. The VHP sterilization transfer window is equipped with a dedicated hydrogen peroxide generator, sterile air supply system, electromagnetic door interlock system, closed system, post sterilization residue removal system, specialized HMI (human-machine interface), and sterilization medium delivery system. Hydrogen peroxide transfer windows are widely used for surface sterilization at room temperature in pharmaceutical, medical, hygiene, biological testing and other places.

Working principle of VHP gasification hydrogen peroxide sterilization transfer window VHP sterilization transfer window disinfection sterilization transfer window:

The VHP sterilization transfer window utilizes the characteristic that hydrogen peroxide plasma has a stronger ability to kill spores at room temperature in gas state than in liquid and vapor state. It generates free H2O2+and H2O2- to attack cellular components, including lipids, proteins, and DNA tissues, break bond connections, and achieve complete sterilization. The VHP sterilization transfer window uses a specialized sterilization medium to give the system a more uniform hydrogen peroxide plasma, achieving sterilization effect.

Dehumidification → Sterilization → Residual Removal → Check Working Status

Dehumidification - circulates the air inside the isolator through the dehumidification device, reducing the relative humidity inside the isolator and increasing the VHP sterilization efficiency;

Sterilization - Input hydrogen peroxide vapor and maintain the expected concentration in the isolator, keep the VHP concentration above 700PPM, and maintain the sterilization time for more than 30 minutes;

Residual removal - Stop inputting hydrogen peroxide gas, switch the sterilization system to the residual removal system, circulate the hydrogen peroxide gas in the isolator through the catalyst for decomposition, reduce the hydrogen peroxide concentration to below 10PPM, and then ventilate to achieve a residual value of no more than 1ppm.

Check the working status - the system switches to the clean maintenance state, automatically adjusts the supply air volume, return air volume, and fresh air volume according to the set working wind speed and positive pressure inside the cabin, maintains the cleanliness and positive pressure inside the cabin, and also detects the cleanliness of the work area online. Floating bacteria sampling can also be manually started.

VHP Gasification Hydrogen Peroxide Sterilization Transfer Window VHP Sterilization Transfer Window Disinfection and Sterilization Transfer Window Technical Features:

1. Automatic leak detection: Automatically inflate the cabin, check whether the system is sealed, and automatically detect the sealing.

2. Quickly vaporize liquid hydrogen peroxide into submicron sized particles, and then produce hydrogen peroxide plasma gas through a plasma generator to improve the efficiency of killing microorganisms.

3. The nano decomposition filter can convert plasma hydrogen peroxide into water vapor and oxygen, with a residual time of only 10-20 minutes.

4. Fully automatic intelligent control, recording the control process, displaying the working status of each component, outputting reports, and providing alarm prompts.

5. The shelf is drawer style, with personalized shelves for each type of packaged item, ensuring that the outer surface of each sample is exposed to the air to the maximum extent, which is conducive to sterilization.

6. The door interlock function ensures that only clean level doors can be opened after the residue is removed. Inflatable airtight doors are used to ensure sealing.

7. Adopting imported EC fans with low power consumption, energy-saving and efficient.

8. VHP concentration, wind speed, pressure difference, temperature and humidity, and form curves and reports. Compliant with computerized certification.

VHP gasification hydrogen peroxide sterilization transfer window VHP sterilization transfer window disinfection sterilization transfer window workflow:

Leakage test before the sterilization cycle begins - Close all valves in the sterilization chamber and observe the pressure rise through a vacuum pressure gauge. If the pressure rise rate meets the program requirements, the system is considered sealed and pre-treatment can begin

1. First, turn on the vacuum pump to evacuate the sterilization chamber and remove moisture and dampness.

2. Open the ventilation valve and flush in dry, sterile air.

When the pressure reaches atmospheric pressure, turn on the vacuum pump again to further dry

5. Inject hydrogen peroxide into the cabin. Due to the high vacuum in the cabin during the pre-treatment period, the hydrogen peroxide is fully diffused, greatly improving the sterilization effect.

After sterilization, the vacuum pump is turned on to reduce the pressure inside the chamber to 1 Torr

7. Open the ventilation valve and flush dry, sterile air into the cabin. When the pressure inside the cabin approaches atmospheric pressure, the vacuum pump starts working to extract the air from the cabin. These residual gases are converted into harmless oxygen and water by the catalytic converter.

8. At the end of the ventilation period, open the ventilation valve and inject a new round of sterile air into the sterilization chamber to restore normal pressure, ending one sterilization cycle.
