Atlas H151 UV Unit

The Atlas H151 UV unit delivers an impressive 151 litres per minute, the highest flow rate in the residential Atlas range.

Maximum Flow Capacity for Demanding Applications

This UV unit makes it the ideal choice for larger homes with multiple bathrooms, commercial kitchen facilities, or properties where several outlets may be used simultaneously without compromising disinfection effectiveness.

Professional-Grade 316L Stainless Steel Construction

Unlike lower-grade alternatives, the Atlas H151 UV unit features a premium 316L stainless steel reactor chamber with a polished internal surface. This marine-grade material offers superior corrosion resistance and longevity, particularly important in harder water areas or where water chemistry may be challenging. The result? A system backed by an industry-leading 10-year reactor warranty.

Intelligent Monitoring That Works for You

The full-colour LCD controller continuously monitors system performance, displaying real-time information in plain English. From lamp life countdown to diagnostic checks, you’re never left guessing about your water quality. The advanced controller automatically detects lamp failure within seconds and can be upgraded with UV intensity monitoring for complete peace of mind.

Future-Proof Investment Protection

Water treatment needs evolve. Perhaps you’ll want UV intensity monitoring next year, or remote alarm capabilities when you install a building management system. The Atlas H151 UV unit’s Infinite Expandability Port means you can add these features whenever needed without replacing the entire system, protecting your investment for decades to come.

Designed for Real-World Serviceability

At 101 watts, the Atlas H151 UV unit’s high-output lamp delivers powerful disinfection whilst remaining energy-efficient. The tool-free twist-and-turn lamp connector means annual lamp changes take minutes, not hours, and you won’t need to call a technician. Every component is designed for the realities of long-term maintenance.

Comprehensive UK Support Network

Canadian engineering excellence meets British service standards. With full WRAS approval, UK-based technical support, and a comprehensive spare parts inventory held in Cambridgeshire, you’re never waiting weeks for overseas components. The QR code on the controller provides instant access to video guides and support documentation.

Universal Power Compatibility

The 90-265V power supply works across all UK voltage variations without modification, making installation simpler and providing protection against voltage fluctuations that can damage conventional UV systems.

Frequently Asked Questions

Q: Can I install the Atlas H151 UV unit outdoors?
A: No. The H151 must be installed indoors in a dry location protected from freezing temperatures.

Q: Do I need the UV sensor module?
A: Whilst not mandatory, the UV sensor module provides real-time monitoring of UV intensity and alerts you to cleaning requirements or lamp degradation before the scheduled replacement date. It offers valuable additional protection.

Q: What happens if the lamp fails?
A: The controller immediately detects lamp failure, sounds a constant alarm, and displays a “lamp failure” warning screen. If the solenoid module is fitted, water flow is automatically shut off.

Q: Can I upgrade my system later?
A: Yes. The H151’s Infinite Expandability Port allows you to add UV sensors, solenoid valves, remote alarms, and other modules at any time without replacing the base system.

Q: How do I know when to change the lamp?
A: The controller counts down lamp life in days. You’ll receive a 7-day advance warning with an audible chirp, and a red alarm screen when the lamp expires.

Q: What’s included in the warranty?
A: 10 years on the stainless steel reactor, 3 years on electronics and controller, and 1 year on lamps, quartz sleeves, and sensors. Full warranty terms apply, see owner’s manual for details.

Q: Is there an installation manual?
A: Yes please see below or visit Atlas UV for additional support.
