LARGE BUILDINGS
Custom solutions for Commercial Buildings
Our UVC technology is proven to kill airborne pathogens, that contaminate recirculating air within commercial air handling systems.
Ensure
Safer
Buildings
Our proven UVC technology provides the security of safe air within buildings, reducing energy consumption while improving occupant wellbeing and performance.
How It Works
Our technology works by ‘killing’ airborne pathogens as they pass through the patented optical cavity. Units can be integrated into existing HVAC systems or established on a standalone basis.
Units are designed and built on a custom basis following a comprehensive study of the building’s internal air speeds and circulation patterns, ensuring maximum performance and energy efficiency.
We lead the world in UVC anti-pathogen efficacy, having proved our technology with the most stringent lab testing. We continue to refine and develop our solutions, ensuring we remain at the forefront of lighting science.
Higher Occupancy
Ensures higher occupancy rates as tenants seek better IAQ and safer buildings
Proven Efficacy
World-leading UVC solution inactivates all airborne pathogens in air circulation
Energy Saving
Safe air allows increased recirculation, saving energy used on heating and cooling
Custom Design
Systems are designed to suit the specific air handling parameters of the building
We offer a complete custom solution. Our modular built units are easily integrated into existing HVAC systems, treating the air before it is circulated through the building.
All air passing through the Optical Cavity will be treated with high-power UVC and airborne viruses, moulds and bacteria will be inactivated. A summary of the testing can be downloaded via the link below.

Proven Performance
A pilot installation on the 2nd floor of Class A London office building allowed us to conduct comparative testing of floors without PRS in the same building.
Using a combination of petri dish analysis and air quality monitoring we were able to demonstrate the following highly compelling performance against bacteria, mould, and VOCs:
KEY BENEFITS
- HVAC energy savings of 10-30%
- Helps ESG and Net Zero objectives
- Customised design and build
- Improves wellbeing and productivity
- Powerful, energy efficient solution
- Easily integrated into existing plant
FAQ
What does the system do?
We offer a range of UVC-based solutions, all using our multi-patented optical cavity and safety design elements, to inactivate pathogens in moving air. This creates safer indoor environments which promote better occupant health and wellbeing. PRS helps reduce HVAC-related energy consumption by safely allowing increased recirculation rates.
Third-party lab testing with live viruses and bacteria clearly demonstrates that our system instantly kills airborne pathogens in fast moving air. This is supported by our London office pilot installation which also tested against mould and volatile organic compounds. Read more about this Case Study here and download testing summaries from our System page.
How do I know it works?
Extensive efficacy testing has been carried out using 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.
Subsequent monitoring of a live site pilot on Canary Wharf supported our rigorous lab testing. Read more about this Case Study here.
Is your system safe?
We have carried out advanced electrical safety testing (to domestic standards) and UVC safety testing. Our multi-patented optical cavity design ensures UVC is contained within the cavity and therefore can not damage infrastructure within existing ventilation systems or pose a risk to personnel.
Safety certification details can be found here.
How does your system integrate into my building?
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.

How does PRS help the environment?
PRS ensures that air within the building is safe. Usually placed after the AHU, the PRS unit treats all air passing through it. This constant treatment allows for higher levels of recirculation which means the air requires less energy to heat or cool it. We estimate that energy consumption can be reduced by 10-30% depending on the original settings. Our London pilot showed an energy saving of 15%.
Levels of filtering can be reduced subject to the objective. PRS will not reduce PM2.5 but will tackle microscopic pathogens. Lowering the level of filtering will save energy and reduce the wear and tear of plant equipment.
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.
What is the lifetime of a unit?
If maintained correctly units will last for at least 25 years.
What are the maintenance requirements?
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.
