General Discription
As a professional manufacturer specializing in the R&D and production of boron diffusion filament furnaces for solar photovoltaic applications, our company has focused on technological innovation in the electrothermal field for twenty years. We possess mature production processes, meticulous and rigorous quality control, ample production capacity, and guaranteed delivery times as a source factory. We have shipped a total of 30,000 units, consistently ranking among the industry leaders. We deeply understand the stringent requirements for thermal field uniformity and stability in photovoltaic cell diffusion and doping processes. Through breakthroughs in multiple core technologies, we provide global customers with efficient and reliable boron diffusion thermal field solutions.
Our boron diffusion filament thermal field is specifically customized for solar photovoltaic thermal process equipment. It employs a vacuum integrated adsorption process, using imported Kanthal heating wire or domestic Shougang heating wire as the heating element. The six-temperature zone thermal field design achieves superior temperature uniformity, rapid heating, low energy consumption, high safety, and easy replacement. It can be used in diffusion, oxidation, LPCVD, PECVD, and other models.
