The efficiency enhancement of the Exc!ter® is the transducer’s sonic waves that cause the large globules of refrigerant molecules to break into smaller globules, increasing the total refrigerant surface area, thus, causing more cooling for the same electricity (= more BTUs per kilowatt hours electricity paid for.)

Using this “de-emulsifying” or “molecular disassociating” method, large globules of refrigerant molecules are broken up into smaller globules creating larger total refrigerant surface area by attaching the Exc!ter® directly to all refrigerant filter / dryers. 

On all circuits.
