- Eliminates the need to buy, handle and store toxic chemicals
- No risk of ‘overdose’ with UV disinfection unlike chemical disinfection
- No risk of residual by-products in your water
- Easy to install into a current water supply
- Inexpensive to purchase and cost effective to run; a Saphir UV water disinfection system uses less power than a regular light bulb
- No alteration of taste, odour or clarity of the water
Where source water is supplied directly from a bore hole, well or spring, or you’re harvesting water or simply living off-grid the compact Saphir is the ideal disinfection solution. Kind to the environment it is high performing and comes with a 10-year chamber guarantee, as standard.
UV is the smart alternative to buying, storing and handling harmful chemicals – simply install & run and have complete peace of mind. The compact, space-saving Saphir system is designed to fit under a regular size kitchen sink, on the incoming main, or to the outlet of a header tank in your loft.
Saphir range utilises mainstream UV lamps that are economical to replace. The single ended UV lamp also makes servicing the equipment very simple.
