The function and principle of VHP sterilization transfer window

The function and principle of the VHP sterilization transfer window:

Introduction of VHP sterilization chamber:

1. Vaporized Hydrogen Peroxide (VHP) generator, which utilizes the advantage that hydrogen peroxide has more sporicidal ability in the gaseous state than in the liquid state at room temperature, and generates free hydroxyl groups for attacking cell components, including lipids, protein, and DNA tissue, to meet the requirements of complete sterilization, a specially designed and manufactured special equipment for the sterilization of confined spaces such as isolation rooms, isolators, transfer cabins, and transfer windows.

VHP generator sterilization principle:

2. The VHP sterilization transfer window is integrated with a vaporized hydrogen peroxide generator, which provides hydrogen peroxide gas to the inside of the transfer window for biological decontamination of the outer surface of the material, so as to avoid the material from the non-grade area or low-grade clean area Entering the A and B key areas will bring pollution. It can be used for all kinds of clean and dry items that need to be delivered in aseptic production, including the outer packaging of packaging materials, instruments, raw and auxiliary materials, accessories, environmental monitoring equipment, etc. entering the critical areas of Class A and B.

Stage 2: Tuning to Steady State

The vaporization unit quickly introduces the hydrogen peroxide gas into the inner cavity of the transfer window to rapidly increase the concentration of hydrogen peroxide gas in the inner cavity of the transfer window

Stage 3: Sterilization

The vaporization unit introduces the hydrogen peroxide gas into the cavity of the transfer window at a low speed to maintain the concentration of hydrogen peroxide gas required for disinfection and sterilization of the cavity in the transfer window

Stage 4: Ventilation and Removal of Residues

After the disinfection and sterilization process is completed, the hydrogen peroxide gas concentration inside the transfer window is removed until the hydrogen peroxide gas concentration is less than 1ppm

VHP sterilization transfer window product features:

1. The overall SUS304 stainless steel structure has the function of an ordinary transfer window, which is durable and easy to clean.

2. The VHP transfer window adopts a double-leaf door structure, which is inflated, sealed, and interlocked to ensure that the doors on both sides cannot be opened at the same time.

3. The air entering and leaving the inner cavity of the VHP transfer window passes through the high-efficiency filter (H14) to prevent the material from being polluted.

4. It has the function of real-time monitoring of temperature, humidity, pressure, and hydrogen peroxide concentration in the inner cavity

5. It has the function of light prompting in each working process, and the operator can operate and monitor the equipment.

6. Siemens PLC's automatic control system is adopted to ensure the stability and reliability of each working process of the VHP transfer window.

7. The real-time printing function can print and record relevant parameters in each working process.
