Why the Hallett 750PN is Better for NZ Installers and Owners

1. Drastically Fewer False Alarms
Standard UV systems often plague owners with false alarms. The Hallett 750PN solves this pain point with its intelligent temperature control, preventing overheating of the lamps or water. Furthermore, the automatic mechanical wiper prevents quartz sleeve fouling, while the air-mounted sensors stay clean, dry, and error-free.

2. Safe and Simple Maintenance
Keep maintenance straightforward and sanitary. The air-mounted lamps and sensors can be easily serviced or replaced without the operator ever coming into contact with raw, potentially contaminated water. Because the quartz sleeve is self-cleaning, there is no need to manually shut down the system and pull the sleeve out for chemical cleaning.

3. Comprehensive Data Monitoring
Tracking compliance is easy. The color touch-screen interface automatically logs and timestamps the last 99 system messages. For commercial properties requiring strict record-keeping, the onboard USB port allows easy data extraction, while dry contacts make building management system (BMS) integration straightforward.
