Thermaflex is literally at your fingertips with this convenient and easy-to-use application for the iPhone. This app allows HVAC engineers to determine the smallest size Thermaflex duct recommended for the installation at hand, based on the project’s specific volume and friction loss. Simply select the Thermaflex product you’re installing, as well as the friction loss and volume present in the system – the app will calculate the velocity of the system and display the appropriate size Thermaflex duct for your application.
