Watts UV Spares

Watts UV Spares

Watts UV spares to fit the Watts steriliser kits - please note these steriliser kits have been discontinued, we can now only supply the spares!

The UV systems are fantastic chemical free disinfection methods, but over time as your ultraviolet steriliser lamps age, the intensity of the UV dose degrades- as illustrated in the graph (additional image). To maintain the correct dose (30MJ/cm²), the lamps should be replaced annually.

If you don't replace your lamps the system will progressively become ineffective.

Remember: It is the UV rays penetrated from these lamps that disinfect harmful pathogens and kill illness-causing microorganisms- the main purpose of the entire system!

Also available are spare Watts quartz sleeve.
