The Inspection, Sealing, and Advanced Cleaning robot, or ISAAC, is created specifically for the inspection and repair of ductwork. The ISAAC HVAC Robotic System is capable of hard-to-reach remediation that would otherwise result in much more costly renovations. It is a robotic vehicle integrated with a digital video recorder that is specifically designed to clean, coat, and seal ductwork of all types. The robot uses lightweight rotary flails to remove contamination and rotary spray nozzles to apply a sealant coating. ISAAC can: Inspect, coat, and seal ductwork from the inside Effectively remove debris in a single pass Provide video footage of interior conditions
