After the foam sprays to an angle of about 240 degrees, the foam stops spraying and clean water begins to be transported in the pipe system. This design ensures that after spraying the foam once, it is immediately followed by a clean water spray to completely remove the foam residue and avoid the mixing of the two foams.
This not only improves the cleaning effect, but also ensures that each stage of the cleaning process can reach the best state, reducing possible chemical reactions or the formation of deposits. In addition, this spraying method also helps save resources and reduce operating costs.
