Cleamix VCS-100Cr bio-decontamination solution
Cleamix VCS-100Cr unit is a very powerful hydrogen peroxide vapour generator. It is
designed for effective bio-decontamination, its hydrogen peroxide vapour output exceeding
650 ppm/m
3
/min at 5ml/min injection rate of 50% w/w aqueous H2O2 solution.
H2O2 vapour like any other gas has good penetration into hard to reach locations and the
sporicidal efficiency of H2O2 vapour is activated already at 100-700 ppm concentrations.
Stable generation and adequate distribution of the active H2O2 agent together with high
quality process parameter monitoring allow accurate and repeatable decontamination
conditions ensuring correct contact times for >6-log microbial reduction. It has been shown
that a wide variety of interior configurations with sealed enclosures can be successfully bio-
decontaminated by hydrogen peroxide vapour.
Appendix II
Controlling a Cleamix VCS-100Cr bio-decontamination process
When optimizing a decontamination process the importance of continuous measurement of
the bio-
decontamination process parameters can’t be over empha sized. The maximum
achievable H2O2 vapour concentration is highly dependent on the existing environmental
conditions - therefore temperature and relative humidity (%RH) need to be taken into
account when planning a decontamination process using H2O2 vapour. The targeted H2O2
ppm level shall be estimated in accordance with the needed exposure time.
When %RH is very high the amount of H2O2 vapour injected to the space is quite limited,
but is related to the temperature. The colder the space the quicker the saturation point is
achieved. This fact makes the relative saturation (%RS) value the only parameter
meaningful for controlling condensation when H2O2 vapour is present. Continuous
measurement of both, water and H2O2 vapour,
enhances the process from monitoring to
controlling.
