AquiSense’s PearlAqua Micro water disinfection range approved by NSF to new Standard 55
Nikkiso Group company AquiSense Technologies LLC of Erlanger, KY, USA (which designs and manufactures water, air and surface disinfection systems based on UV-C LEDs) claims Class B component certification for its PearlAqua Micro range.
Multiple models were tested and certified by NSF International (which develops public health standards and certification programs that help to protect food, water, consumer products and environment) in compliance with the new NSF/ANSI 55-2019 standard for disinfection performance, materials compliance, and structural integrity. Standard 55, Class B, certifies ultraviolet water systems for supplemental bactericidal treatment of disinfected public drinking water and is commonly specified for drinking water products. As the first range of products using mercury-free, instant-on, UV-C LED technology, this opens considerable opportunities for use in residential and commercial point-of-use water dispensers, reckons AquiSense.
The PearlAqua Micro is claimed to be the smallest UV-C LED water treatment system, and production has already exceeded 10,000 units per month. The platform includes five discrete model sizes and a range of custom variants offering flow rates of up to 8 liters per minute (LPM). Supplemental third-party disinfection validation in accordance with US EPA UV Disinfection Guidance Manual protocols show up-to 6-log (99.9999%) bacterial reduction, with additional certifications and compliance including: Watermark - AZ/NZS 3497:1998; EMC - EN 55022; CB scheme - IEC 60335 & IEC 62471; CE; RoHS; REACH; Japan Food Sanitation and Water Works Law (pending); and WRAS - BS 6920 (pending).
This wide range of certifications make the PearlAqua Micro platform the most extensively tested UV-C LED water treatment product on the market, it is claimed. It is manufactured in the AquiSense Kentucky, USA facility to ISO-9001:2015 quality standards.
“Our team has worked for years supporting NSF International to ensure the new 55 Standard is robust and future-proof,” says chief technology officer Jennifer Pagan PhD. “Our OEM partners will now benefit from the added claim of integrating an NSF-certified component.”
