New Energy & Photovoltaics
In the photovoltaic industry, where high-temperature processes define both efficiency and cost, reliable refractory and insulation materials are indispensable. Hongda’s advanced polycrystalline mullite fiber solutions provide superior thermal management across the entire PV value chain:
· Polysilicon reduction furnaces – delivering stable insulation and energy savings in the foundation of silicon production.
· Thin-film deposition furnaces (CdTe, CIGS, and others) – ensuring precise temperature control and consistent film quality under demanding thermal conditions.
· Photovoltaic glass annealing lehrs and melting furnaces – enhancing energy efficiency, protecting thermal stability, and improving product yield.
With outstanding energy-saving performance, our materials help manufacturers significantly reduce energy consumption, enhance production yield, and lower operating costs. By reinforcing the thermal backbone of PV manufacturing, Hongda supports the global transition to cleaner, more sustainable energy.
