Replaceable UVinaire


UVinaire is a replaceable LED lamp module that is the heart of the PearlAqua. Easily replaced at the end of its 10,000 hour life, it includes a safety interlock switch and on-board data logging.

Real-Time Performance Monitoring

Options for monitoring lamp operation, lamp intensity, and alarm conditions. Remote start/stop operation with unlimited cycles per day.

Environmental Friendly UV-C LEDs

Utilizes small, state of the art UV-C LEDs, which provide instant full power and unlimited on/off cycling without the use of harmful chemicals or traditional UV lamps.

Flexible Operation

Designed to go above and beyond, powered with 12 V DC, solar or battery is a realistic option. With a high IP rating, the PearlAqua reliably treats water in the most remote places.

LEDs do not transfer heat to the water, thus limiting fouling and ensuring a constant UV output regardless of water temperature. 

Temperature Independent 


The PearlAqua platform is the most certified and tested UV-C LED product range in the world - boasting certifications from NSF, WQA, ISO, Reach, IEC, Watermark, and more.
