VHP decontamination units

Vaporized hydrogen peroxide (VHP) decontamination equipment sterilizes surfaces inside sealed spaces. The family covers three unit types. VHP fumigation pass boxes handle small items moving from non-sterile to sterile areas: the vaporizer raises the peroxide concentration in the chamber, holds it through the exposure phase, then removes the residue below 1 ppm before the inner door opens. VHP decontamination transfer rooms apply the same cycle to large loads between functional rooms, first dehumidifying the air, then holding a VHP concentration above 700 ppm for at least 30 minutes, then catalytically breaking the residue down below 1 ppm. Vaporized hydrogen peroxide generators vaporize a 35% hydrogen peroxide solution and distribute the gas into isolators, pass boxes, biological safety cabinets and small cleanrooms, where a micro-condensation phase lets it reach pores, gaps and shadowed areas for a 6-log kill.

Features

• Common cycle structure: conditioning, vapor injection and hold, then catalytic breakdown of the residue below 1 ppm.
• Residue-free sterilant: hydrogen peroxide decomposes to water and oxygen.
• Transfer-room versions hold VHP above 700 ppm for at least 30 minutes for load decontamination.
• Generators vaporize a 35% hydrogen peroxide solution and serve isolators, pass boxes, safety cabinets and small rooms.
• PLC control with touch-screen HMI; cycle parameters are set per load and run without continuous supervision.

Applications

• Isolators, pass boxes and biological safety cabinets in pharmaceutical plants
• Decontamination of materials entering aseptic processing areas
• Hospital wards, operating rooms and laboratory spaces
• Food packaging lines and equipment decontamination
