NOL series Characterlistics

Reduce O&M cost

UV Solaray Lamp Technology

- NEOTEC’s UV Solaray La mp Technology i ncreases energy efficiency, extends lamp life, and provides not only the best quality and performance but also cost-efficiency.

Ensure appropriate UV dose is maintained

UV Intensity Sensor

- UV sensors measure the UV intensity in real time and monitor output in response to changes in water quality and lamp aging.

Provide the ease of maintenance

Module Lifting Device

- With help of integrated lifting module, maintenance such as lamp replacement can be done with ease, and cost of hoi st installation can be saved.

Quartz sleeve cleaning system

Motor-Driven Automatic Wiper Mechanism

Motor-driven automatic wiper mechanism cleans sleeve so UV lamp can deliver the UV dose in order to achieve optimal disinfection performance.
