Innovas Secures Patent for Advanced Chiller Monitoring System
CORALVILLE, IA — November 2025 — Innovas Technologies, a leader in automated tube cleaning and fouling prevention for water-cooled chillers and heat exchangers, is proud to announce the issuance of U.S. Patent No. 12,422,411, titled “System and Method for Monitoring and Diagnosis of Heat Exchanger Tube Health.” The patent was officially granted by the United States Patent and Trademark Office (USPTO) on September 23, 2025, extending protection through February 22, 2044.
This new patent reinforces Innovas Technologies’ commitment to pioneering solutions that optimize the efficiency, reliability, and sustainability of district cooling and industrial process systems.
A New Standard in Chiller Performance Monitoring
The patented technology represents a breakthrough in continuous fouling detection and system diagnostics for chiller operations. It provides a data-driven approach to identifying tube fouling in real time, allowing plant operators to monitor performance degradation before it impacts efficiency.
By integrating this monitoring system with the company’s flagship Helios Automatic Tube Cleaning System, Innovas is advancing the state of predictive maintenance—helping customers reduce energy consumption, eliminate manual cleaning cycles, and extend chiller life.
A wireless sensor ball is used in conjunction with an ultrasonic acoustic reciever enabling monitoring of chiller systems without interruption to the system or requiring operator intervention.
Building on a Legacy of Innovation
“This patent further validates Innovas’ position at the forefront of energy-efficiency technology for water-cooled systems,” said Charles Dirks, President of Innovas Technologies. “Our engineering team continues to develop innovations that help customers achieve world-class operational performance, reduce energy costs, and meet their reliability goals.”
The company’s growing intellectual property portfolio underpins its ongoing development of next-generation products, including Helios Sentinel Diagnostics, which leverages smart sensors and analytics to optimize chiller operation across global installations.
Protecting and Extending the Technology
The patent covers a term of 20 years from the application filing date, extended by 436 days due to USPTO administrative delays. Innovas Technologies now holds the exclusive right to manufacture, market, and implement this monitoring technology in its product line.
