VHP transfer window

1. (VHP) transfer window is a special equipment used for sterilization of confined spaces such as isolation rooms and isolators. "Minimize the risk of contamination of products or processed materials with particles or microorganisms". Improve the requirements for small items between the clean area and the clean area, the non-clean area and the clean area, reduce the number of door openings in the clean room, and reduce the pollution and cross-contamination in the clean area. The vaporized hydrogen peroxide aseptic transfer window independently developed by our company sterilizes all exposed surfaces in the transfer window through integrated vaporized hydrogen peroxide sterilization, replacing the traditional UV disinfection method.

2. The laminar flow protection of the filter that comes with the transfer window will form an airlock when the double-fiber gate is opened to prevent cross-contamination. Vaporized hydrogen peroxide achieved a 6-log kill rate against Bacillus stearothermophilus (MESA LABS/ATCC7953). Vaporized hydrogen peroxide is sterilized at low temperature and normal pressure, and is suitable for low-temperature sterilized products. Vaporized hydrogen peroxide has good material compatibility, is easily decomposed, has no harmful residues, and decomposes into water and oxygen. The concentration of hydrogen peroxide is 75ppm, and the occupational exposure (8h) is 1ppm.

3. Working principle Hydrogen peroxide low-temperature sterilizer (VHPS), which takes advantage of hydrogen peroxide's advantage of more sporicidal ability in gas state than liquid state at room temperature, generates free hydroxyl groups, which are used to attack cell components, Including lipids, proteins and DNA tissues, to meet the requirements of sterilization,

4. Technical parameters:

5. Main functions Siemens Programmable Logic Controller (PLC) program control; touch screen humanized interface design; double-door electromagnetic interlock; date and time display; hydrogen peroxide concentration monitoring (optional); vertical airflow protection; vaporization Hydrogen peroxide sterilization function; data storage function; data USB export; efficient PAO detection port.

6. Technical features: ※Low temperature sterilization process can be sterilized in the range of 4~80℃; ※There are few residues, the decomposition products of hydrogen peroxide are water vapor and oxygen, and there are no toxic by-products, which is an environmentally friendly sterilization Technology, and does not require cleaning; ※ Fast sterilization cycle process, low operating cost, and easy to verify; ※ Hydrogen peroxide gas has material compatibility; ※ Has bactericidal effect, suitable for killing fungi, bacteria, viruses and spores .
