Operation of the HPVPA disinfection process

The effectiveness of our process lies in the dry, cold diffusion of a stable, ready-to-use hydrogen peroxide and peracetic solution, X-CID. This automatic process is conducted with no human presence in the room and guarantees optimal reproducibility. Its effectiveness has been validated in accordance with European standard EN 17272: 2020.

The biocidal solution acts as a non-specific oxidant: it destroys bacteria, spores, fungi and yeasts, viruses and mycobacteria including tuberiferous bacilli.

Diffused homogeneously in the form of dry mist by our RHEA Compact and RHEA Titan units, X-CID reaches all surfaces, even those least accessible: ceiling, top of walls, light strip, under the bed, table or armchair.

Greater effectiveness with boosted hydrogen peroxide

Hydrogen peroxide is a powerful bactericidal agent. However, to be effective, it must be heated to at least 60°C and used in high concentrations, which makes it corrosive: it can therefore damage surfaces, paint and coatings in the room treated. In addition, its action is slow.

To improve its effectiveness and prevent any damage to surfaces, we developed the X-CID stabilised solution: with a low hydrogen peroxide concentration, it is boosted by the addition of peracetic acid.

6 good reasons to choose HPVPA surface disinfection technology

  • Process validated in accordance with standard EN 17 272: 2020
  • Effective at room temperature thanks to hydrogen peroxide boosted with peracetic acid
  • Destruction of all microorganisms, including resistant spores
  • Non-corrosive to materials, even electronic devices, and not aggressive for coatings
  • No residue on surfaces after treatment
  • Traceability: up to 500 disinfection cycles saved with our RHEA devices for the enhanced monitoring of your procedures
