VH2O2 Biodecontamination Systems – Centralized Systems and Mobile Units
The automatic biodecontamination of surfaces by dry fogging with liquid disinfectant (12% H2O2 solution) is an alternative technology to the direct vaporization (known as VHP). This methodology is increasingly being implemented because new solutions available are easier to validate, more economical and not corrosive.
The systems developed by SOLIDFOG specifically for the pharmaceutical industry generate a dry fog that is distributed homogeneously occupying the entire volume. In fact, the dry fog vaporizes until the saturation point is reached. Hence, it can also be called VH2O2.
Scientific studies have shown that the biocidal effect is produced precisely by the microcondensation of vaporized hydrogen peroxide on saturation (MCHP), acting by contact on surfaces.
SOLIDFOG’s DOSYMIST® range of solutions can be adapted to all types of installations, from large areas with complex architecture to small volume applications such as isolators or SAS. SOLIDFOG has also developed equipment and systems for the rapid catalysis of the peroxide NEUTRAMIST® whenever ventilation systems of the facility are not adequate.
The main advantages are:
Simpler process. It does not require dehumidification or conditioning of the area to be treated. Air handling systems are not used to distribute the peroxide since the dry fog generation system provides an even distribution.
Less corrosive The biocide solution has lower concentration of H2o2 (12% versus 35%) so there is less risk of corrosion by an excess of condensation

> Simpler process. It does not require dehumidification or conditioning of the area to be treated. Air handling systems are not used to distribute the peroxide since the dry fog generation system provides an even distribution
> Less corrosive process. The biocide solution has lower concentration of H2o2 (12% versus 35%) so there is less risk of corrosion by an excess of condensation
> Faster process. There is not as much absorption on materials at the end of the cycle because of the lower concentrations used and leveraging the effect of micro-condensation, so the aeration phase becomes shorter
> Lower biocide consumption. The cycles are not carried out maintaining a constant concentration during the contact phase and, therefore, peroxide is not consumed in that phase. It’s simply injected the right amount to achieve the microcondensation effect
> Possibility of centralized control with fixed nebulizers and also with mobile units. It is possible to develop hybrid solutions, combining fixed and mobile systems managed by a central control system
