Features
Read full description

This app is built for all levels of restorers in the water mitigation industry. For the first time ever these proprietary algorithms and metrics will give the restorer complete control of their drying chamber regardless of the size, class, equipment used or outside conditions instead of the restorer being controlled by their chamber. The keystone metric for this app is the patent pending E3 metric that can evaluate the exact evaporation ability of any condition in a drying chamber and the daily E3 targets that have been set for all different types of drying equipment for all possible water classes and outside conditions. This metric also allows for all different types of equipment to be specifically ranked or compared to prove which is the best for any job scenario.
