About the UV-STICK-SCR
The Light Progress UV-STICK-SCR is a modular coil UV-C system installed directly inside air-conditioning and HVAC equipment to keep cooling coils, heat exchangers and filter systems clean and hygienic. Fitted within the air handling unit (AHU), it delivers continuous UV-C germicidal irradiation onto the surfaces where moisture, dust and organic matter would otherwise accumulate. In doing so, UV-STICK-SCR inactivates viruses, bacteria, fungi and spores, and prevents biofilm from forming on cold registers, heat-exchange surfaces and filtration stages. For UK facilities and building services teams seeking dependable AHU coil cleaning UV-C, it offers a compliance-led approach to indoor air hygiene and system protection.
Continuous HVAC coil disinfection at the source
Cooling coils and heat exchangers operate wet, dark and nutrient-rich — ideal conditions for microbial colonisation. Left untreated, biofilm and deposits of bacteria and mould spores build up across the coil face, becoming a reservoir that the airstream can carry through the building. UV-STICK-SCR addresses this at source: sustained coil UV-C exposure stops biofilm establishing on cold registers, heat exchangers and filter systems, and halts the accumulation of bacterial and fungal deposits. By suppressing microbial growth continuously rather than periodically, the system helps maintain consistently cleaner surfaces throughout the operating season.
Efficiency, energy and maintenance benefits
A fouled coil is an inefficient coil. Biofilm and deposits insulate heat-exchange surfaces and restrict airflow, forcing the plant to work harder to achieve the same conditions. Keeping cooling coils clean of biofilm is a well-established route to restoring heat-transfer efficiency and airflow — a recognised energy and maintenance benefit of coil UV-C. With UV-STICK-SCR maintaining clean surfaces, facilities can reduce maintenance, disinfection and operating costs while raising overall system efficiency. Fewer manual coil cleans, less downtime and improved heat transfer combine to protect both the equipment and the operating budget over the life of the AHU.
Managing airborne infection risk in AC systems
Air-conditioning systems can inadvertently create conditions that favour hazardous micro-organisms. UV-STICK-SCR counters the growth conditions inside AC systems that favour Legionella pneumophila, tuberculosis (TB) and influenza, reducing the microbial burden associated with the coil and drain-pan environment. As part of a considered indoor air-quality and building-hygiene strategy, HVAC coil disinfection with UV-C complements — rather than replaces — sound maintenance and water-management practice. UV-STICK-SCR is available on a 30-day trial and priced on application, quoted in GBP, EUR or USD.
