The Ultrasonic Gas-phase Cleaning Machine is sealed type with manipulator driving transportation rack, loading by special material baskets, step-type conveying cleaning technology and pneumatic elevator to transport material. Using organic solvent such as trichloroethylene as the cleaning medium to degrease the surface of the workpiece. Then having freeze-drying. The supersonic cleaner is suitable for the cleaning of the heat exchanger parts.

The principle of gas-phase cleaning machine is as follow. When the solvent is heated, the steam forms the gas phase zone. In this area, the oil on the surface of the workpiece is dissolved and washed by steam. When the steam condenses, the dirt along with the grease falls back into the tank to become the cleaning fluid. Then, the cleaning fluid is heated and gasified into steam to clean the workpiece. This continuous cycle ensures the workpiece is always surrounded by the steam of cleaning fluid which overcomes the problem of contaminated cleaning fluid in the past common cleaning process.
