Piping System

For effective spray cleaning, nozzle pressure should be at least 105 kPa (15 psi) to provide adequate mechanical action at the surface of the workpiece. Higher pressures can be used, but they tend to atomize more of the emulsion, which increases the risk of flash. The nozzles should be readily accessible and removable for cleaning. To prevent overspraying, end nozzles in the cleaning and rinsing chambers should be deflected inward approximately 30°. All nozzles should be staggered to ensure complete coverage of the workpiece.
