Description
The Polaris high-flow UV steriliser range covers commercial and industrial water treatment applications from 170 LPM to 604 LPM. Choose the model that matches your required flow rate, from the UVA-1440HO at 170 LPM through to the UVA-5040HO at 604 LPM.
Each unit uses validated HO (high output) UV lamps rated for 9,000 hours of continuous output, housed in a stainless steel chamber for long service life and consistent UV performance.

- Inactivates micro-organisms within seconds, with no chemicals or by-products
- Inactivates chlorine-resistant parasites, including Cryptosporidium and Giardia, plus E. coli and viruses
- Durable stainless steel chamber maintains UV light integrity over time
- The controller displays the days of use and alarms on lamp failure
- Simple installation and low-maintenance operation
Why You Need It
UV sterilisation neutralises bacteria, viruses, and protozoa at the point of use, making it a practical fit for food processing sites, rural water schemes, and any operation that needs continuous, reliable water safety without dosing or residual chemical taste. Because output degrades gradually even while the lamp still glows, the lamp should be replaced every 12 months to keep protection at full strength.

FAQs
How do I choose the right model for my application?
Match the model to your peak flow rate, not your average. If your system needs to handle 400 LPM at the busiest times, choose the UVA-3600HO (422 LPM) or higher rather than sizing to average daily flow.
Does water pressure affect UV disinfection performance?
Yes. Dwell time inside the chamber decreases as flow rate increases, which is why each model has a fixed maximum flow rate. Running above the rated LPM for a given model reduces UV dose and disinfection reliability.
Can these units run continuously, or do they need to be switched off overnight?
They’re designed for continuous operation. The controller display keeps track of lamp hours regardless of flow, so there’s no need to power down between uses.
What water quality is required before the UV chamber?
Water should be pre-filtered for sediment and have reasonable clarity, since suspended particles can shield micro-organisms from UV exposure and reduce effectiveness. A pre-filter stage is recommended if your supply carries turbidity.
What happens if the lamp fails while the system is running?
The controller display raises an alarm on lamp failure, so you’re alerted immediately rather than unknowingly running unsterilised water through the system.
Is a quartz sleeve required, and does it need separate maintenance?
Yes, the UV lamp sits inside a quartz sleeve within the stainless steel chamber. The sleeve should be checked periodically for scaling or fouling, since a coated sleeve blocks UV transmission even with a healthy lamp.
Annual Maintenance
Replace the UV lamp every 12 months regardless of appearance. UV output degrades over time even when the lamp is still glowing. Check out our replacement lamps and replacement parts collection.
