Bioquell - Bio-decontamination with Hydrogen Peroxide Vapour

Bio-decontamination within a room or chamber is achieved by depositing an even layer of micro-condensation of H2O2 over all surfaces. Micro-condensation may be defined as a microscopic film of H2O2, which, being at a sub-micron level, is invisible to the naked eye. Scientific research has proven that it is this low temperature, residue-free deposit that actually deactivates micro-organisms during the gassing process. The micro-condensation process ensures that the optimum conditions for biological inactivation are achieved.

HYDROGEN PEROXIDE VAPOUR (HPV) GENERATOR AND A HIGH-VELOCITY GAS DISTRIBUTION SYSTEM

The combination of a Clarus® Hydrogen Peroxide Vapour (HPV) generator and a high-velocity gas distribution system provides an even spread of H2O2 vapour to all areas of a room or enclosure.

This system is operated at ambient room temperature and relative humidity, without the need to attain significantly reduced humidity traditionally associated with HPV systems. The benefit of being residue-free means that the necessity to wipe down surfaces on completion of the decontamination process is eliminated.

FULLY MOBILE DECONTAMINATION SYSTEM

Bioquell's fully mobile decontamination system is ideal for any room that will be subject to periodic decontamination. This is the easiest and most cost-effective way to sterilise rooms.

This type of decontamination system can interface with the building ventilation system throughout the aeration phase of the decontamination cycle, provided that there are gas-tight dampers fitted that can be operated from outside the room.

The mobile decontamination system involves positioning the Clarus HPV generator in the contaminated zone and connecting to a local power supply. A fixed or dual rotating vapour distribution nozzle is then mounted directly onto the generator. A remote control cable plugs into the rear of the generator, which terminates at the Siemens remote-control panel within an adjacent area. This control lead can pass either through an interface panel or simply underneath the door seal. The cycle can now be initiated from this point, capturing all relevant cycle data with full controllability.

SEMI-PERMANENT ROOM DECONTAMINATION SYSTEMS

Semi-permanent room decontamination systems are suitable for any room that will be subject to periodic decontamination, and where there is restricted access for wheeled equipment due to step-over benches, etc.

System set-up involves mounting a vapour injection nozzle directly onto the inside of a wall interface plate and using fixed vapour distribution fans to ensure correct vapour distribution. This type of system is particularly suited to containment laboratories because there is no need to access the room to set up equipment in the event of a biological spillage. The decontamination cycle can be run, monitored and controlled from the Clarus HPV generator outside the room.

PERMANENT AND FIXED ROOM DECONTAMINATION SYSTEMS

Permanent fixed decontamination systems are suitable for any room requiring regular decontamination as well as GMP facilities where personnel and equipment access into the area should be minimised. This type of system is only suitable for use with rooms where the HVAC system can be used for aeration.

System set up involves positioning the Clarus HPV generator in the decontaminated zone, and connecting the vapour supply and return hoses to the trace-heated and insulated vapour supply pipe and the insulated vapour return pipe.

REMOTE CONTROL OF THE DECONTAMINATION CYCLE

Where required, a communications link from the Clarus C to the building management system can be installed, which will allow the ventilation dampers to be automatically opened at the start of the aeration phase of the decontamination cycle.

Within the room, rotating vapour distribution nozzles are permanently fixed in the ceiling and are fed via the vapour supply pipe. The decontamination cycle can be run, monitored and controlled from outside the room.
