20 Litre Specifications, Features & Compatibility Guide

UV-C sterilization works through photochemical disruption rather than thermal or chemical kill mechanisms. When UV-C photons at 254 nmnm wavelength strike nucleic acids (DNA/RNA) in microorganisms, they cause thymine dimers to form — covalent bonds between adjacent thymine bases that prevent normal DNA transcription and replication. The result is cellular death without leaving chemical residues on treated surfaces. The 8 W - 15 WW lamp intensity determines the UV dose delivered per unit time. UV dose (mJ/cm²) is the product of irradiance and exposure time — to achieve 99.9% inactivation of E. coli, a minimum dose of approximately 7 mJ/cm² is required. The 15-30 minutes cycle of the 20 Litre is calibrated to achieve this dose at the designed lamp-to-surface distance. The lid-open safety shutoff in the 20 Litre uses a simple magnetic or mechanical interlock that breaks the lamp power circuit immediately when the lid is lifted. This is not merely a software switch — it is a hardware interlock that cannot be bypassed by software failure, ensuring UV-C exposure to skin and eyes is impossible during normal operation. UV-C LED technology differs from traditional low-pressure mercury lamps in both safety and longevity. LEDs contain no mercury, making disposal safer and eliminating the breakage hazard of glass mercury tubes. With a 6000-8000 hours-hour lifespan, the LEDs will outlast most product use cycles without replacement, maintaining consistent germicidal output throughout.
