The Inspection, Sealing, and Advanced Cleaning Robotic System, or ISAAC for short, is the newest product from Carlisle HVAC. ISAAC is the company’s answer to cleaning and sealing inaccessible ductwork. ISAAC aims to improve indoor air quality and decrease heating and cooling costs without significant interruption to building occupants. The robotic system is capable of hard-to-reach remediation that would otherwise result in much more costly renovations, officials say. Carlisle representatives say that with ISAAC, it is no longer necessary for employees to crawl into ductwork and cut access holes every 8 feet. The system is also equipped with an integrated digital video recorder which, combined with the included personal computer software, creates an inspection and documentation tool.
