The degas function is used for degassing the cleaning liquids and allows some sound/chemical applications to be adopted, e.g. degassing of high polymer solvent (HPL). During this function, the detergent solutions are released from air bubbles which prevent effective propagation of the ultrasound waves. Whenever a new detergent or water is used, a degassing cycle of approximately two minuts is recommended in order to bring the air bubbles to the surface. Higher temperatures not only affect the quality of cavitation, but also help to degas the liquid and improve the chemical cleaning action. A big and unheated ultrasonic tank could require several hours to degas. The amount of dissolved gas decreases with increasing temperature. It's important to start the degas function before cleaning parts and after the detergent or chemical is added.
