The Philips NaturalTrust UV-C LED Modules are designed to treat ambient water (> 8°C - sealed nut version) and cold water (< 8°C - sealed nut version with cable). The UV-C LED module emits UV-C radiation which, in laboratory tests, has been shown to inactivate 99.9% of E-coli 1 . Because of their small size, the modules are designed to fit appliances where conventional mercury discharge lamps cannot be integrated, such as refrigerators, coffee machines, ice makers etc. It operates on low voltage DC below 24V. In cold conditions such as cold water reservoirs or refrigerators, there is no UV-C output drop like with conventional mercury discharge lamps.
1) In a study conducted by the National Institute of Public Health-PZH (Poland) in a laboratory setting, these LED UV-C modules irradiating various samples of water inoculated with Escherichia coli ATCC 8739 (E-coli) inactivated 99.9% of E-coli in 20 minutes (1 liter sample), 30 minutes (2 liter sample) and 60 minutes (5 liter sample).
