About the customer
Located in the renowned polysilicon base of the central and western regions — the Ordos Qipanjing Industrial Park, Inner Mongolia ERDOS Polysilicon Co., Ltd. is a wholly-owned subsidiary of the famous Erdos Group. It is a high-tech, green manufacturing enterprise specializing in the research, development, production, and operation of high-quality polysilicon products, with an annual production capacity of 8,000 tons of polysilicon.
The challenge
Polysilicon production is a core upstream process in the photovoltaic and semiconductor industries, involving purification and processing of high-purity silicon. It requires continuous operation in ultra-clean environments with complex processes and extremely high requirements for temperature, pressure, and purity control.
Reduction Furnace: Used to reduce silane gas into polysilicon, requiring extremely precise temperature control and gas flow stability.
Purification Column: Purifies silicon materials through chemical reactions, requiring stable internal pressure and temperature.
Wafer Slicing Machine: Cuts silicon ingots into wafers, requiring high precision of cutting tools and highly stable cutting speed.
Stringent Production Continuity Requirements
Unplanned downtime disrupts polysilicon production continuity, and high-purity silicon retained in equipment is easily contaminated or degraded.
Difficulty in Monitoring Early-Stage Failures
Long inspection intervals make early faults difficult to detect, and early abnormalities in seals, pipelines, or pumps may be overlooked.
High-Temperature Conditions Accelerate Equipment Degradation
High-temperature and high-load conditions accelerate component degradation, causing heating elements and internal assemblies to wear more rapidly and making early changes difficult to detect through manual inspection.
