Why Trade Professionals and Facility Managers Choose Hallett:

No More Annoying False Alarms

Standard UV systems often trigger false alarms when water sits idle and overheats, or when sleeves get slightly dirty. The Hallett 500PN solves this. The integrated temperature control system prevents overheating. The automatic mechanical wiper keeps the quartz sleeve clear of fouling, and the air-mounted sensors prevent sensor fouling. This means fewer late-night service calls and uninterrupted water supply.

Hassle-Free, Safe Maintenance

Maintenance is incredibly simple and hygienic. Because the UV lamps and sensors are air-mounted, they can be replaced without the operator ever coming into contact with potentially contaminated water. There is no need to drain the chamber or risk leaking seals during routine servicing.

Simple, Audit-Ready Monitoring

With built-in data logging via the USB port, a time-stamped alarm history, and easy integration into building management systems (BMS) via dry contacts or optional MODBUS, proving Taumata Arowai compliance to water quality auditors is straightforward and stress-free.
