The whole machine adopts modular structure design, which is convenient for disassembly and assembly. Compared with the traditional integrated design, it has greater advantages, convenient maintenance, faster repair, and saving manpower and time costs. Adopt PC + PLC control system, Chinese-English window operation interface, with automatic storage function of process curve / data, low and high flux level alarm and low tin level alarm. Vertical spray design, more penetrating, software path optimization can save 27% flux, any combination of hot air and infrared modules, the best performance. The nozzle and the flow channel are provided with a diversion device, the variable nozzle of the anti-oxidation sleeve, the integrated funnel shape of the impeller, the new invention patent, and the anti-seizure is more effective.
