The System

Future proofing spaces against airborne pathogens

Scientific Solutions

We offer a complete anti-pathogen solution for commercial air handling in large, enclosed spaces. Our UVC systems can be retrofitted and are manufactured on a bespoke basis, to suit the required volume and speed of airflow of your air-handling system.

Patents-pending and world class bio-lab verified, PRS instantly inactivates airborne pathogens traveling through its optical cavity, ensuring safe air and an infection resilient environment. Testing has proven the effectiveness of our system on SARS-CoV-2, Influenza A, Measles, and Aspergillus Niger. The results of live virus testing can be found below.

In addition to air safety, PRS also provides sustained economic and environmental benefits. The ability to safely recirculate air significantly reduces energy costs and importantly, carbon footprints.

Technical Specifications

Our systems have undergone rigorous technical and scientific testing to demonstrate operational efficacy and performance. PRS is undoubtedly the leading technology in its class, and it will lead the drive for infection resilient environments and improved IAQ for years to come. 

We are continually adapting and advancing our technology, ensuring we remain the leading experts in our field. To date we have filed four patent applications and there are more in process. 

We have the only UVC-based solution able to successfully treat large volumes of air traveling at speed. This makes PRS the ideal technology for large buildings, hospitals, and vessels. Not only can we ‘kill’ any pathogen, but we can also do it very safely, as our UVC safety testing at LUX TSI demonstrates. Details of all our technical and scientific testing can be downloaded from the panel on the left.

UVC Safety Measures

High intensity UVC 254nm light is utilised, to inactivate pathogens, within our systems. UVC radiation is a danger to human beings, as well as many susceptible materials, and we understand how important it is to you that any equipment installed is safe for the people, the infrastructure, and materials more generally within your spaces.

It is particularly important, therefore, that we highlight the safety measures that have been designed into our systems which include:

  • UVC containment section – eliminates UVC leakage outside the optical cavity, ensuring UVC light cannot bleed, avoiding damage to existing plant, building materials, and ensuring the safety of occupants and maintenance personnel.
  • Automated cut-off – this mechanism turns off the UVC light source in the event no airflow is detected, the system auto starts once airflow resumes.
  • Power interlock – automatically turns the power off if anyone attempts to open the PRS
  • Safety maintenance key – ensures that the system cannot be turned on during maintenance

Integration into Existing Ventilation

PRS technology takes proven science and adapts it to suit the target environments and objectives. We cover diverse sectors, each with specific needs, and we have a solution for all. The premise of ‘air conditioning’ has been around for decades but how this is provided varies greatly between environments. 

The primary plant equipment in a modern, commercial air conditioning systems is the Air Handling Unit (AHU). The AHU processes all the air before it is released into circulation. Fresh air from outside is drawn into the system, where it is filtered and temperature-managed, to ensure a constant and comfortable atmosphere for occupants. PRS units are installed in the supply-side ducting, after it leaves the AHU. This ensures that all air, whether recirculated or fresh, has been treated so that no pathogens are in circulation. 

Some buildings use localised systems known as Fan Coil Units (FCUs). They are much cheaper than large air-handlers however far more are required, and their serviceable life is short in comparison to AHU based systems. The advantage of fan coils is that we can prioritise specific areas, such as hospital wards, by installing a small PRS unit on a few FCUs without having to a build large system servicing the whole floor. 

In areas where there is no mechanical ventilation we provide ceiling-based units that use and integrated fan to draw air through the system to ensure fully treated air. 

Whether installed in a specific location or building wide, PRS will ensure that any airborne viral load, within that area, will be removed every time the air is exchanged. The result is the same.

In order for us to better understand the potential benefits of installing PRS in your space we are happy to complete a free Desktop Review. This can typically be done by simply providing site schematics, airflow metrics and photographs of the current systems in place.
