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.

This high-precision design demands exactness within a tolerance of 50 microns and ensures impeccable flatness with no leakage.
  • 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.
