UV sterilisers that disinfect without chemicals.
SovSafe sterilisers use ultraviolet light to inactivate bacteria and viruses as water flows past. Nothing is added, so taste and minerals stay the same. Choose a whole-site unit or a compact one for a single outlet, installed by our team in the UK.
Whole site or a single outlet.
Choose by where the water needs protecting. UV works best on filtered water, so every system starts with the right pre-filter.
Point of entry
A stainless-steel steriliser on the main supply for large homes, villas, boutique hotels and cafes. Ideal after storage tanks.
- Up to 5.4 m3/h
- 1.5" connection
- Stainless chamber, quartz sleeve
- 9,000-hour lamp, about one change a year
Point of use
A compact unit that fits inside a sink cabinet, for under-sink filters, water dispensers and vending machines.
- 0.22 m3/h (60 GPH)
- 30 mJ/cm2 dose at 254 nm
- 270 × 52 × 90 mm, 1.3 kg
- Draws 10 W
Filter plus UV
UV needs clear water, as particles can shade microbes from the light. We fit the right filter before the steriliser.
- Mechanical pre-filtration first
- Chlorine taste removed with carbon
- UV as the final barrier
- One team to install and service
Two sterilisers, whole site to single tap.
Both SovSafe models, side by side.

Light that stops microbes from multiplying.
UV-C light damages the DNA of bacteria and viruses, so they cannot reproduce. It is a physical process: nothing goes into the water.
Filter first
Pre-filtrationWater passes a mechanical filter before the steriliser. Clear water lets the light reach every microbe.
- Sediment and particles
- Cloudiness that shades microbes
- Chlorine taste (with carbon)
Why it matters: Pre-filtration is required for UV to work as designed.
UV chamber
UV-C at 254 nmWater flows through a stainless chamber around a lamp in a quartz sleeve, receiving a measured dose of UV-C.
- Bacteria
- Viruses
- Up to 99.9% at the DNA level
Why it matters: It disinfects without chemicals, so taste and minerals are unchanged.
Keep it working
Annual serviceLamps lose strength with use, so they are changed at around 9,000 hours, about once a year.
- Lamp hours
- Quartz sleeve clean and clear
- Pre-filter condition
Why it matters: A tired lamp or dirty sleeve lowers the dose.
UV does not remove hardness, chlorine or particles. It is the final barrier after filtration, not a replacement for it.
Safer water, nothing added.

Part of a system, not a bolt-on.
We fit SovSafe as the last stage of a treatment system, after the right filter, so the dose is delivered as designed.
- Sized to your flow, not a guess
- Pre-filtration matched to your supply
- Stainless chambers with quartz sleeves
- Pair with a maintenance plan from a fixed annual fee

Supplied, installed and serviced across the UK
Across most of southern and eastern England, mains water is very hard. Rain filtering through chalk and limestone dissolves calcium and magnesium, and that scale coats heating elements, so we size every system to your supply and your equipment.
Tell us about your site and what you need the water for. We specify the system, fit it and keep it running under Comprehensive Maintenance.
