How Steritroxing works
Steritroxing controls and exploits the killing power of advanced oxidation technology in a way previously unavailable. The key technology that the Steritroxing process utilises to deliver its huge sterilising charge is based on the production of free radicals through the generation of aqueous ozone.
Free radicals are powerful bactericidal and virucidal agents which are managed safely, effectively and efficiently by an advanced control system.
This vapour diffuses into every corner of the workspace, bathing all exposed surfaces and penetrating deep into hidden areas and fabrics.
The free radical cascade destroys molecular biofilm and exposes resistant environmental contaminants to a natural biocide to which they can develop no defence. Put simply, bacteria are unable to build resistance to this form of attack.
Towards the end of the programmed cycle a further catalyst is injected that creates a secondary burst of free radicals massively enhancing the kill rate for a further short period and then quickly absorbs the remaining ozone concentration down to a safe level for personnel to re-enter the room, all typically within one hour. The speed at which Steritroxing reduces ozone concentration to a safe level is something that no other system can match, meaning that production down-time is kept to a minimum.

The table left shows the oxidising potential of various reagents. Hydroxyl free radicals are more effective than other oxidising reagents in the fight against harmful micro-organisms.
The technology is proven and has been confirmed by Campden and Chorleywood Food Research Association and Manchester University.
The Steritroxing killing cycle
Phase 1
The ozone within the Steritroxing vapour initially addresses the latent contaminants present in the area workplace - called ‘ozone debt absorption’
Phase 2
Having overcome this the vapour concentration builds rapidly fuelling the Steritroxing reaction
Phase 3
Sophisticated software in the equipment maintains the optimum biocidal level by being adaptive to changing environmental conditions for the minimum time needed for maximum kill
Phase 4
The final phase of the cycle dramatically accelerates the free radical cascade to consume all of the residual elements of the room clean, safe and fresh for immediate re-occupation
Steritroxing in action
Figure 1 shows actual results over the first five consecutive days of Steritroxing in a high-care food preparation unit. Total Viable Count (TVC) swabs were taken at a number of high risk locations immediately before and after Steritroxing on each day and sent to an independent UKAS registered laboratory for processing.
