Initiation — vaporisation begins
Dwell — 6-log₁₀ kill · all surfaces
Aeration — return to safe 1 ppm level for access
01Initiation Phase
H₂O₂ (35–50% Food grade) vaporised 0.25nm molecules generated. Vaisala sensors continuously monitor RS% relative saturation — system prevents saturation, no condensation risk.
- Vaporation — not large 10µm aerosol droplets
- RS% monitored in real time
- Any Food grade 35-50% H₂O₂ supplier
02Dwell / Decontamination Phase
Generator maintains Vapour ppm concentration and dwell time while preventing saturation and condensation. 6-log₁₀ kill occurs across all surfaces including hidden cavities. Vapour not affected by gravitational pull.
- Relative Saturation RS% control without condensation
- 0.25 nm molecule penetrates everywhere even passes through HEPA/ULPA
- Full 6-log kill — biological indicator confirmed
03Aeration Phase
Using a catalyst it rapidly accelerates the decomposition of over 400ppm of vaporised H₂O₂ into water vapour O₂ and oxygen H₂O to a safe level of 1 ppm in just minutes rather than hours for an aerosol, where typically 24+ hours required for fumigation in an OT.
- Catalyst: H₂O₂ → H₂O + O₂
- Access for 1ppm safe level in minutes from 400ppm
- Electronic treatment profile generated for QA logs
