Ultraviolet water disinfection using state of the art LED's. Chemical free whole house point of entry or point of use pathogen control for your drinking water. Instant on/off kill intensity automatically switched with water flow provides intelligent power usage and prevents hot water slugs. Compared to Mercury lamps which are on maximum output all the time, heat up the water when there is no flow and/ or have multiple lamp failures due to over heating, LED UV-C Systems Ltd provides advanced power modulation technology when flows fluctuate and 5,000 hours of 'Lamp On' time with unlimited on/off cycling.
