Sani UV-C Submersible In-Tank Water Steriliser for Tanks, Reservoirs & Borehole Storage

Sani UV-C Submersible In-Tank Water Steriliser

The Sani UV-C Submersible In-Tank Water Steriliser is a premium chemical-free water disinfection solution designed for stored water applications, including water tanks, reservoirs, borehole storage systems and rainwater harvesting setups.

Installed directly inside the tank, the submersible UV-C lamp works by emitting UV-C light into the water volume, helping neutralise bacteria, viruses and other microorganisms without the use of chemicals, ozone or taste-altering additives.

This locally manufactured system is ideal for residential, agricultural, commercial and industrial water storage applications where reliable stored-water hygiene is required.

How It Works

The UV-C lamp is submerged inside the tank and positioned to treat the stored water volume. UV-C light helps disrupt microorganisms in the water, providing ongoing disinfection without adding chemicals to the water supply.

The control box is mounted externally and connected to the submersible lamp using the supplied waterproof connection system. The installation manual specifies that the lamp should be positioned approximately 5cm above the full water level and that the control box should remain visible and accessible for monitoring and maintenance.

Maintenance

Routine maintenance is simple. The UV-C lamp should be replaced approximately every 24 months or 9,000 effective operating hours, depending on system usage.

Replacement lamps are available separately for the 40W, 55W and 145W models.

• Do not power the unit on until fully installed
