WET STEAM OR SUPERHEATED STEAM
By combining ultrasonic and / or high pressure cleaning with blasting the surface with superheated steam, in certain applications the performance of aqueous cleaning systems can be further optimized with regard to the surface purity to be achieved. Thanks to compact, aerodynamically optimized jet nozzles in the process zone, systems with small dimensions can be realized.
The steam generated in an electric steam generator can be additionally heated to temperatures of 200-250 ° C and flows with a pressure of 6 bar and a temperature of 150-200 ° C from the radiation nozzles on the wire or profile surface.
Oily residual contaminants are reliably removed by the high temperature and kinetic energy of the steam jet. At the same time, the dry, superheated steam with its high heat transfer ensures rapid drying of water-wetted surfaces.
When cleaning copper flat wire for photovoltaic (PV-Ribbon) after rolling at a line speed of up to 1000 m/min, residual carbon contents of less than 0.002 mg/cm² could be achieved by a perfectly to the process matched combination of ultrasound, high pressure and steam.
