MILTON, N.Y.— Sono-Tek Corporation (OTCQX: SOTK), the leading developer and manufacturer of ultrasonic coating systems, today announced the sale of its 300th ultrasonic coating system for manufacturing fuel cells and electrolyzers.

Notably, the 300th machine sale was a large platform electrolyzer coating system, directed at converting environmentally harmful CO2 emissions into a useable fuel source.  The end product produced by Sono-Tek’s customers for this market can help reduce the global carbon footprint by implementing it onto large carbon emitting manufacturing processes, while creating a revenue stream from the fuel byproduct.

When Sono-Tek first started tracking this industry in 2008, the market was just emerging, and the Company quickly realized that the inherent benefits of its proprietary ultrasonic spray coatings provided significant advantages to fuel cell manufacturers in the development of Solid Oxide Fuel Cells (“SOFC”), Proton Exchange Membrane (“PEM”) fuel cells, and electrolyzers. Over the years, Sono-Tek’s sales to this market have steadily increased as demand from new and repeat customers increased as coating systems began to be developed for production scale manufacturing rather than primarily R&D, when the industry was first developing. This transition toward machines capable of higher throughput has driven average selling prices from less than $50,000 per unit to an average selling price of well over $150,000 per unit, and fully automated production lines can sell for over $400,000.

The Company further leveraged its growing knowledge and expertise with these coatings to enhance the capabilities of its spray equipment specifically for electrocatalyst spray applications and to expand Sono-Tek’s offerings to include what is now a full line of spray machines and configurations. Recent additions have been the ExactaCoat OP3 and VersiCoat conveyorized enclosure for continuous coating lines, with oversize options and expanded automation features. New features include Sono-Tek’s DuraFlow pump for high flow continuous applications, PEM inverters, and active flow rate monitoring that help support the growing requirements for production fuel cell applications.

New developments and advances to Sono-Tek’s systems are identified from customer relationships and requirements and developed in-house by the Company’s highly skilled team of five applications engineers and 15 product engineers.

Brian Booth, Electronics and Advanced Energy Division Director at Sono-Tek, noted, “The 300th sale milestone caps an exciting journey over the past 10+ years. During that time, we’ve witnessed the industry transform from mostly R&D systems to growing demand for the production of significantly more complex, high speed, customized solutions for both fuel cells and electrolyzers.  Our technical team has excelled in satisfying customer challenges for scale up, creating a bright outlook for the future of Sono-Tek as one of the go-to suppliers in the industry.”

Bennett Bruntil, Vice President of Sales and Marketing at Sono-Tek, added, “Sono-Tek’s sales and innovation to the fuel cell/electrocatalyst industry have remained robust despite the impact of the global pandemic on many industries.  We are proud to be part of the path that is developing a growing hydrogen infrastructure where renewable energy from solar and wind can be converted into hydrogen fuel.  Since our coating technology is used in both the supply and consumption of hydrogen, we believe that we are part of the solution and positioned to make a significant impact on a cleaner energy future.”
