As a science-led company we believe that the highest quality testing should be carried out with ‘live’ pathogens, rather than surrogates, and that test conditions should be as close to real works as possible.

To this end, efficacy testing has been carried out with live pathogens: Measles, Flu A, SARS-CoV-2, Mycobacterium Parafortuitum, Micrococcus Luteus, and Aspergillus Niger, in a Bio 3 safety level Laboratory, using a modified ASHRAE 185/ISO 15714 single pass testing standard protocol. Our adaptation meant tougher testing: air speed increased from 2.5 m/s to 6m/s, creating a residence time of only a sixth of a second, and the use of live viruses instead of surrogates.

Details of testing can be found here.

We have carried out advanced electrical safety testing (to domestic standards) and UVC safety testing. Our patented optical cavity design ensures UVC is contained within the optical cavity and therefore can not damage infrastructure within existing ventilation systems or pose a risk to personnel.

Safety certification details can be found here.

We all need safe air to breath. Beyond that simple statement every space is different. The great thing about PRS is so are we.

Being a science-based company, we view problems differently. We have solutions, tested efficacy, and scalable design, and we can apply this to Any Pathogen – Any Space – Any Environment.

PRS systems can be integrated into existing plant, whether that is a centralised HVAC system, localised fan-coils, or rooms without any existing mechanical air-handling. We look at your space, existing plant, and individual needs, then build a specific solution for you.

The need for infection resilient environments and better indoor air quality IAQ is a given, trying to balance this with our moral and legislative duty to reduce carbon emissions can seem like opposing goals. PRS with its unique approach, and patents pending design features can help you achieve both.

Being able to recirculate air, because it has been safely treated to inactive pathogens, removes the need to heat and cool vast amounts of air within your environment, saving fuel and reducing equipment degradation, reducing your carbon footprint. 

No other units on the market today produces higher levels of UVC irradiation as a ratio to energy usage than PRS, together with our bespoke design for every environment and world leading test data we are able to maximise efficacy whilst minimising power consumption, again helping your carbon footprint. 

Continuous product development has led to the use of material components that last longer, for example lamps last 60,000 hrs meaning less raw material used.

If maintained correctly units will last for at least 25 years.

Bio-annual checks should be carried out. As with all mechanical equipment, some parts will need to be periodically replaced over the life of the system. For example:

– Lamps burn for 60,000 hours.

– Ballasts typically last 5 years.

Individual maintenance contracts are designed for each client’s needs.
