Atlas H53 U unit

The Atlas H53 UV unit delivers 53 litres per minute, specifically designed for typical family water consumption patterns.

Perfect for the Average Family Home

Two showers, kitchen taps, toilet cisterns, and domestic appliances can operate comfortably within this capacity, providing full disinfection protection for homes with 2-3 bathrooms without the cost of over-specification.

Space-Conscious Installation

At just 508mm long, the Atlas H53 UV unit is one of the most compact high-output UV systems available. The short chamber length makes it ideal for installations where space is limited, under stairs, in utility cupboards, or compact plant rooms. You’re not compromising on performance; you’re choosing efficient engineering.

High-Output Lamp Technology

The 45-watt high-output lamp delivers superior UV intensity compared to standard output equivalents. This concentrated UV energy means effective disinfection in a shorter chamber length, whilst the 10,000-hour lamp life matches larger systems for consistent annual maintenance schedules across all your equipment.

Universal Voltage Operation

The 90-265V power supply automatically adjusts to supply voltage variations, providing stable operation across the UK’s electrical network. No voltage-specific models, no configuration switches, simply plug in and the system adapts. This universal compatibility also protects against voltage fluctuations that can reduce lamp life in conventional systems.

Exceptionally Low Running Costs

At just 48 watts total power consumption, the Atlas H53UV unit costs approximately £50-60 per year to run continuously, less than many standby appliances. Over a 10-year operating life, this efficiency delivers significant savings whilst providing uninterrupted whole-house water disinfection.

Visual Communication That Actually Helps

The full-colour LCD controller displays system information in clear, understandable language. No cryptic error codes or flashing LED patterns, just straightforward messages telling you exactly what’s happening and what action (if any) you need to take. The lamp life countdown keeps you informed weeks in advance of required maintenance.

Built for British Water

WRAS approval confirms the Atlas H53 UV unit meets UK drinking water treatment standards. Combined with 316L stainless steel construction (superior to the 304 grade used in many competing systems), the Atlas H53 UV unit is engineered specifically for the mineral content and chemistry typical of British private water supplies.

Genuine Upgrade Path

The Atlas H53 UV unit isn’t a locked-down appliance. Today it provides essential lamp monitoring and countdown. Tomorrow you can add UV intensity sensing when water conditions change. Next year you might integrate it with a new building management system using the volt-free contact module. The expansion port means your system grows with your needs.

Maintenance You Can Actually Do

Tool-free lamp changes. Simple twist-off quartz sleeve access. Clear visual instructions via QR codes. The Atlas H53 UV unit is designed around the principle that maintenance you can do yourself is maintenance that gets done, protecting your water quality long-term.

Frequently Asked Questions

Q: Can I install the Atlas H53 UV unit outdoors?
A: No. The Atlas H53 UV unit 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 Atlas H53 UV unit’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.
