Solar cell proliferation are mainly open tubular and close tube soft landing proliferation in two forms

Closed tube phosphorus diffusion, with directional recycling process exhaust gas cooling device, Metaphosphate, CL2, separate collection and handling; technology waste gas collected from the rear directional discharge; various process gases can be separated into the quartz tube, process gas (Phosphorus oxychloride) spray way to introducing the quartz tube can be used. Close tube soft landing diffusion process free from outside interference, and process quality are fully protected.
Automation: automatic control temperature and process. Master temperature control module is imported, the control accuracy of ± 0.25 c.
Access methods: cantilever push-pull the boat. Cantilever push-pull side layout structure is adopted, can effectively prevent metaphosphoric acid drip, resulting in push-pull bodies from corrosion, affecting the accuracy of the push-and-pull bodies.
