Simultaneous airborne and surface decontamination and disinfection systems

The significance of PDX's atomisation technology lies in its capability to generate a very high number of extremely small droplets at a very high flow rate: the size of the droplets is between 2-5 microns in diameter and it is estimated that circa half a trillion droplets are produced per second*. The resultant aerosol is gas-like in behaviour, remains in suspension for far longer than traditional fogs and ensures an even and consistent coverage which provides effective decontamination of both airborne and surface threat. Because of this super-efficient dispersion, comprehensive coverage can be achieved using very little fluid. The atomisers are compact and lightweight and can either be used to achieve whole room filling or directional decontamination.

The Atomiser can be easily directed and controlled. Its capability provides simultaneous (and consistent) surface and airborne decontamination against chemical, biological and radiological threats and hazards.

The facts:

Proven to rapidly fill large volume space capability (~2000m3). 1 minute for 40m3 room (mach 3 delivery).

Proven consistent and even coverage. Ratio between visible surface and non-visible surface deposition is the key parameter**

Sensitive and electronic equipment stays functional throughout disinfection process e.g operating theatres and wards.

Proven efficiencies. PDX atomiser uses typically 3-5% of the agent required by existing chemical decontamination systems.

Compatible with a wide range of off-the-shelf chemistries.

Proven to be 17 times more effective than conventional systems available. * (VBDC Comparison)

Highly mobile and robust technology- designed for flexibility and independent operation for deep clean or daily control.

The flexibility of the Atomisation Technology means we can offer a dual use delivery system that eliminates both chemical and biological threats. The atomiser delivers both mist and CAF allowing for decontamination and fire suppression in one unit. The PDX atomisation technology is compatible with a wide range of off the shelf chemistries.

Flexibility is something you're very likely to be looking for when searching for your decontamination solution. PDX Atomisation Technology can be deployed in a number of ways: man portable, mobile and built in. Its designed with maximum flexibility in mind and independent operation. This helps PDX meet your individual requirements more closely than ever before.

Commercial Disinfection

PDX is working with their partners to develop products integrating the atomisation technology to deploy a number of highly effective chemistries. Due to the movement and fineness of the mist, the decontaminant reaches and delivers a consistent even coverage to all line and non line of site surface.

By comparison most fogging technology currently available uses vaporization as a means of mist generation rather than atomisation. Both thermal and electrostatic vaporization are slower and less efficient in terms of chemical degradation and time. For disinfecting a hospital room, rapid turnaround is key: the PDX Atomiser requires only one minute filling a 40m³ room using little more than 1 litre of water.

Because of the low volume of fluid used, sensitive and electrical equipment can remain in-situ and stays functional during process.

Nuclear site decommissioning

NDX Solutions, a JV between PDX and National Nuclear Laboratory (NNL), has identified multiple unique applications for use in nuclear decommissioning including complex decontamination solutions for plants and equipments. NNL is a leader in the provision of technology services to the nuclear industry.

Fire suppression

PDX's fire suppression technology protects interior structures and buildings, regardless of a fire's location. In addition, PDX's small droplet size means that fire suppression through PDX's misting technology is much more effective: smaller droplets increase the surface area which speeds evaporation and displacing oxygen.

PDX has licensed its atomisation technology for fire applications to Tyco, a world leader in fire suppression. Tyco's Aquasonic product, "a revolution in Class B fire protection technology" extinguishes fires using only one-third of the water used by high-pressure water mist systems. The dense cloud of tiny droplets generated also produces superior fire suppression as the Atomiser fills a space rapidly, requires only one-third of the water of high-pressure water mist systems, and offers protection for an internal area regardless of the fire's location. Aquasonic is certified by FM Global, a global provider of independent testing and certification.
