“What is Predictive Maintenance?”
Guests: Tim Darrah – Intelligent Systems and Rick Bennet – National Facilities Solutions
Tim served 7 years in the U.S. Army as an airborne infantryman and later as an avionics maintenance technician. In 2017, Tim graduated from Tennessee State University with a bachelor’s of science in computer science prior to entering the Ph.D. program at Vanderbilt University. His focus at Vanderbilt is on extending the current state-of-the-art in health management technologies for cyber-physical systems to include system-level prognostics, predictive maintenance, and decision making.
In 2019 he started his company, Intelligent Systems, and has been working with National Facility Solutions to develop their flagship product, Facility Coach, which gives Facility Managers the predictive edge when it comes to maintenance and indoor air quality. In 2020 he was awarded a prestigious NASA Fellowship to support his thesis research and is working towards embedding the technology behind Facility Coach into iPerformance (National Facility Solutions product), so that he can focus on finishing his degree.
Rick has over 25 years of experience in the HVAC industry as a service technician, supervisor, instructor, designer and Commissioning Engineer. His areas of expertise include high- and low-pressure chillers, large DX systems, DDC controls, pneumatics, hydronics, air makeup, computer room systems, process equipment, steam high and low pressure, and frequency drives.
