Submersible UV Sterilisers for Water Tanks

Our Submersible UV Sterilisers are designed specifically for installation inside water storage tanks, reservoirs, and cisterns, offering an effective final disinfection stage to ensure microbiologically safe water. These units emit germicidal UV-C light (254nm) that neutralises bacteria, viruses, protozoa, and other pathogens, without the use of chemicals or chlorine.

Perfect for rainwater harvesting systems, borehole water storage, and off-grid tanks, submersible UVs are easy to install, fully waterproof (IP68), and ideal for tanks where inline UV disinfection is not practical. Commonly used in domestic, agricultural, and light commercial applications.
