Five considerations for upgrading an existing UV Pure system

Over 18,000 UV Pure systems are operating worldwide – with many providing years or even decades of reliable disinfection performance in potable, wastewater, and reuse applications. Over time, requirements for some sites can change, leading operators to evaluate different disinfection options to cope with higher flow requirements, changing water quality, emerging pathogenic threats or other factors.

The introduction of UV Pure’s new Hallett product line addresses these upgrade challenges with new technology, higher-capacity flow rates, and lower power consumption while continuing to provide the low-maintenance, highly reliable performance that operators trust from UV Pure.

As the UV Pure team prepares to ship the first of these new Hallett systems in early 2019, we share some answers below to common questions about the new units.

How are the new Hallett units similar to UV Pure’s proven Hallett 15xs and Hallett 30 systems?

The new Hallett units are still powered by UV Pure’s patented Crossfire Technology™, which includes automatic self-cleaning wipers, smart sensors, and built-in purging to prevent fouling of the quartz sleeve by mineral scaling and biofilm. This makes Hallett systems up to 10 times more effective in difficult water applications than conventional UV systems.

How are the new Hallett systems different from existing Hallett units?

The new Hallett units have been completely redesigned with better features and operability. The new systems can handle flow rates of up to 100 gpm (378 L/min) per unit while continuing to provide robust, reliable disinfection under the toughest conditions. For higher flow applications, multiple Hallett units are connected to achieve flow up to 1 MGD (3,785 m3/day).

What happened to UV Pure’s Upstream products?

Upstream systems will be discontinued in early 2019, but UV Pure will continue to offer replacement parts and full product support for years to come. New Hallett NC systems will replace Upstream models for disinfection applications that do not require product certification or validation.

How does UV Pure ensure its systems provide the appropriate level of public health and environmental protection?

UV Pure is offering a new Hallett system that is validated to the US Environmental Protection Agency’s (EPA) UV Disinfection Guidance Manual (UVDGM) protocols, as well as to the National Water Reuse Institute’s (NWRI) UV Disinfection Guidelines for Drinking Water and Water Reuse.

What type of warranty is available for replacement lamps?

UV Pure continues to offer a 12-month limited warranty for LPHO lamps, while amalgam lamps in the new Hallett 1000 model will be covered for 16 months.

Discover the NEW Hallett 1000: Smart new features, same trusted name

Operators can now virtually eliminate concerns about maintenance, active supervision, and performance reliability for on-site UV disinfection at commercial, industrial, and municipal water or wastewater plants up to 1 million US gallons per day (3,785 cubic metres per day). How?

UV Pure’s new Hallett™ 1000 systems have more capacity than ever, plus the performance, power, and smart technology you expect from UV Pure.

The new Hallett 1000 model builds on the success of UV Pure’s proven Hallett 30 system and patented Crossfire Technology™. This technology uses a unique elliptical reflector design with dual air-mounted lamps to deliver a high UV dose and target pathogens from 360 degrees.

New and improved features of the Hallett 1000

Longer lamp life:

Each Hallett 1000 unit is equipped with high-output, long-life low-pressure high-output (LPHO) amalgam UV lamps that are powered by a UL-certified pre-heat ballast with a soft start. This helps extend their operating life to provide maximum UV output for up to 12,000 hours, or approximately 16 months.

Larger capacity system, same reliable disinfection:

The new Hallett 1000 units can handle flow rates of up to 100 gpm (378 L/min) per unit while continuing to provide robust, reliable disinfection under the toughest conditions. For higher flow applications, multiple Hallett 1000 units are connected with a prefabricated pipe manifold to achieve flow up to 1 MGD (3,785 m3/day). This modular design provides built-in redundancy and ensures the highest level of protection since one or more Hallett systems can be shut down for service while others continue to operate.

Space-saving, easy-access vertical design:

The new Hallett 1000 systems incorporate a newly designed aluminum outer shell with side hinges that can easily be flipped open to access the internal components. This design even further reduces the Hallett installation space requirements on a wall or as part of a vertical-mounted manifold system, and allows operators to quickly change lamps without having to pull them from the fragile quartz tube.
