Technical Specifications
Key Features
Dual Lamp Power Configurations
Available in 120 W and 320 W lamp versions with 3U to 12U lamp arrays, allowing precise sizing for each application's flow rate and dose requirements.
Automatic Compressed-Air Cleaning
Built-in self-cleaning mechanism driven by compressed air keeps quartz sleeves clear of fouling, maintaining UV output without manual intervention.
SS304 Chamber with Dual-Finish Surface
Mechanical polishing on the inside and sandblasting on the outside ensure long-term corrosion resistance and maximum UV reflectivity.
PLC Touch Screen Cabinet Controller
Full-featured UV controller with PLC and touch screen display for flow rate, UV intensity, running time, ON/OFF status, and fault indication.
SS316L Upgrade Option
Optional SS316L chamber material with temperature sensor and Low Pressure Amalgam lamp upgrade for more aggressive water chemistries and 11 Bar operating pressure.
9,000–12,000 Hour Lamp Life
Long-life low-pressure UV lamps reduce replacement frequency and lower total cost of ownership for high-utilisation municipal and industrial installations.
