US Electric Technologies’ new innovative patented Refrigerant Exc!ter® Technology provides a low-resistance path to refrigerant flow through the original refrigerant filter / drier with minimal effort to install. 

The Exc!ter® is an electronic device that sends sonic vibration harmonics waves into the filter/ dryer to cause the debris and fouled oil films to disperse and migrate deeper into the filter / dryer - thus opening and clearing the main refrigerant flow channels without disturbing the integrity of the filter / dryer.
