Offgrid UV-C LED Module (15 LPM)

Flow-activated UV-C sterilisation for pre-filtered water, stored tank water, rainwater systems and mains-fed installations. 8 year lifespan never change the bulb! 99.999% disinfection rate. The Offgrid Water UV-C LED Module adds a microbiological treatment stage for water that has already been filtered. As water flows through the unit, UV-C LED light at the precise wavelengths of 260–280nm neutralises bacteria and microorganisms that may still be present. It is designed as an add-on, not a standalone system. It works best after sediment and carbon filtration, where the water is already clear - this allows the UV-C light to work most effectively. Unlike traditional mercury UV systems, this module is flow-activated - it only switches on when water moves through it. This reduces power use, extends LED lifespan, and makes it well suited to boats, campervans and off-grid setups running on 12V or 24V DC. A 220V AC adapter can also be used where mains power is available. Typical installation points After Stage Two, before your taps - adds UV-C to your general water supply After Stage Two but before FinalStage RO - adds an extra sterilisation pass before drinking water reverse osmosis Before a cold water tap - galley, sink, campervan or point-of-use On stored tank water - treats water that has been sitting before it enters your system. We advise using a Stage Two filter too. This module is designed for pre-filtered, clear water. UV-C is less effective on dirty, cloudy or coloured water. For canal, river or rainwater use, install as part of a wider filtration system.
