RTU Rooftop units explained. In this video we’ll be looking at how RTU’s work to learn HVAC engineering. We’ll be starting with the basics and looking at different 3D models to cover the internal components such as dampers, fans, filters, cooling coils etc. We’ll also look at typical setups to help you build your base knowledge.
