VHP Pass Box

What is the VHP Passbox?

The VHP (Vaporized Hydrogen Peroxide) Pass-Through Window is primarily utilized for the biological decontamination of materials’ outer surfaces, preventing contaminants from entering high-level areas from non-classified or lower-classified zones. This system employs an external hydrogen peroxide generator (VHPS), operating under low-temperature and standard pressure conditions, ensuring an environmentally friendly and efficient decontamination process.

Product Features

Sealing Performance: Achieves biological safety standards with pressure decay of less than 0.5%Vol/h at ±2000Pa over 20 minutes.
Sterilization Efficiency: The entire sterilization cycle (including residual removal) takes as little as 30 minutes, shortening processing time by 50%-70% compared to similar market offerings.
VHP Generator: Utilizes complete vaporization with a multi-channel labyrinth module to prevent condensation and fogging during sterilization.
The Seal Door Types of VHP Passbox: Available in inflatable seal and mechanical compression styles, with the inflatable variant featuring high-density EPDM imported from the Netherlands, rated at 60±5° Shore A, and hinges cleverly concealed.

Door Handles: Designed for both inflatable and mechanical pressure models. Inflatable pressure model includes a protective handle to prevent accidental pressure rebound injuries. Mechanical pressure model is crafted from durable SUS304 stainless steel through CNC machining for longevity, strength, and fatigue resistance.
Liquid Weighing: Employs a gravity sensor for precision measurement and can be set and adjusted according to specific usage.
Communication with BMS Systems: Capable of online and remote printing, as well as data storage.
Temperature Stability in Sterilization: Minimal change, with an optional configuration keeping within ≤3℃, ideal for sensitive biological transfers like serum.
Independent Air Supply and Exhaust: Built with standalone air ducts, the unit comprises integrated supply, exhaust, and recirculation fans and can connect to customer HVAC systems.
Functional Versatility: Equipped with a feature switch that toggles between VHP sterilization transfer mode and standard self-cleaning UV sterilization transfer mode, selectable via touchscreen (optional configuration).
Sturdy Door Construction: Both sides of the door are made from fully welded 3.0mm stainless steel sheets, with built-in double-layer 5mm tempered glass.
Safety Assured: Rounded corner welding and comprehensive sanding ensure safe use and mitigate collision risks that could lead to glass breakage.
Built-In Biological Safety Valves: Internally equipped with airtight butterfly valves to minimize the risk of hydrogen peroxide leakage during sterilization.

Technical Specifications

Power Supply: Operates on a single-phase AC 220V/50Hz power source.
Efficiency Level: Supply air features HEPA H14 filtration; exhaust air also utilizes HEPA H14 filters.
Sterilization Temperature: The temperature range for sterilization is between 18-35°C.
Sterilization Pressure: Operable at 0-100Pa for sterilization processes.
Decontamination Cycle Time: Less than 120 minutes to complete a decontamination cycle.
Inflation Pressure & Timing: Achieves an inflation pressure of 1.5kg/cm2 with inflation and deflation times of less than 5 seconds, capable of more than 10,000 cycles without bursting or leaking.
