No-Contact Maintenance
Built-in safety features prevent operator exposure during maintenance.
Low Operating Cost
Engineered to cut down on recurring costs like chemical cleaning and quartz replacement.
Quick Installation
The plug-and-play design enables easy installation of one or more units where you need them.
Modular Redundancy
Easily configure multiple units for redundancy at a fraction of the cost of large conventional systems.
360 Degrees of Coverage
Powerful UV disinfection from every angle for excellent performance in very hard water and low UVT applications with Crossfire Technology.
Three Systems. Every Application.
Each Hallett series is purpose-built for its application -- serving commercial, municipal, agri-food, healthcare, and industrial operations. Select a series to configure your system.
Hallett P Series
Potable Water Disinfection -- NSF/ANSI 55 Class A, 61 & 372 certified. Effective in UVT as low as 35% with hardness up to 855 mg/L.
Hallett W Series
Wastewater Disinfection -- EPA UVDGM validated. Self-cleaning design handles high turbidity and fouling with less pre-treatment than conventional systems.
Hallett R Series
Reuse & Rainwater -- NWRI validated. Purpose-built for water reuse, rainwater harvesting, and reclaimed water with iron tolerance up to 3 mg/L.

Engineered for the
Toughest Water
Conventional UV systems struggle with hard water, high turbidity, and low transmittance. Crossfire Technology was designed to thrive in exactly those conditions—delivering effective disinfection in water with UVT as low as 35%, hardness up to 855 mg/L, and iron up to 3 mg/L.
Whether it's a single unit for a rural well system or a prefabricated multi-unit array for a municipal treatment plant, Hallett systems scale to match your operation without compromising performance.

Game Changing Evolutions
Four breakthrough technologies that set Crossfire apart from every conventional UV system on the market.
360° Protection
Dual air-mounted lamps inside a unique elliptical reflector concentrate sterilizing UV from every angle. Pathogens have nowhere to hide -- penetrating radiation reaches every point in the water column, eliminating UV shadowing even in water with high suspended and dissolved solids.
Self-Cleaning
An automatic wiper continually scrapes mineral buildup and biofilm from the quartz sleeve, preventing fouling and maintaining peak UV dose delivery -- no manual intervention required. This allows Crossfire to handle wastewater, rainwater, and groundwater with far less pre-treatment than conventional systems.
Smart Sensors
Dual smart sensors continuously monitor UV dose, lamp intensity, and net UVT in real time. Onboard data logging, optional 4-20 mA and Modbus outputs, visual/audible alarms, and self-diagnostics eliminate nuisance alerts and minimize downtime.
Modular Redundancy
Stack multiple compact units for additional capacity and built-in redundancy at a fraction of the cost of large conventional systems. Prefabricated manifold or cabinet configurations adapt to variable flow and water quality so disinfection performance is always achieved.
Certifications & Validations
UV Pure products have certifications that meet safety and technology standards around the world. Product performance is validated with third-party testing in accordance with globally recognized water industry standards.
