We have several different methods, but all use panels containing 100% natural minerals known as desiccants. In walk-in coolers, we attach a series of specially designed panels to the ceiling. For homes, a different type of panel(s) is placed in the return airflow. These are simply stood up behind the air filter. For large buildings and such, our panels are either placed into the return air flow or installed in the plenum chamber section of the air handling unit. Whichever the method, or specific product, our panels begin working once they are placed into the conditioned environment.
