China Suppliers Factory Solar Thermal Oven Belts for Efficient Module Assembly and Wafer Drying Solutions
Products Description
Our solar drying oven mesh belts use 316L stainless steel with anti-static coating, designed for PV backsheet E-coating and pre-lamination drying. Chemical-resistant structure withstands acid washdown.
Jiangsu Huada’s PV cell drying oven belts are engineered for critical moisture removal in monocrystalline/polycrystalline silicon production. Our 316L stainless steel conveyor systems deliver:
- < 5ppm residual moisture (verified by FTIR analysis)
- 30% faster drying cycles vs. conventional mesh belts
- Zero metal contamination (ICP-MS tested to <0.1ppb)
Key Applications:
- Post-texturing cleaning drying
- PSG removal rinse drying
- Edge isolation process drying

Frequently Asked Questions
What materials are used in your solar drying oven mesh belts?
Our drying oven mesh belts are manufactured using high-quality 316L stainless steel equipped with an anti-static coating, ensuring durability and safe operation.
What level of residual moisture can be achieved?
Our systems deliver exceptional drying capabilities, achieving < 5ppm residual moisture, which is strictly verified by FTIR analysis.
How does the drying speed compare to conventional belts?
Thanks to the 85% open area design for laminar airflow and mirror-polished surface, our belts provide 30% faster drying cycles compared to conventional mesh belts.
Are these drying belts safe for handling thin wafers?
Yes, they are ESD-safe (surface resistance 10⁶-10⁹Ω) and feature rounded edge guides that significantly reduce the breakage rate to <0.05% (0.03% for 160μm wafers).
Can the belts withstand harsh chemical washdowns?
Absolutely. The chemical-resistant structure withstands 1-10% HF / HNO3 residuals and successfully passes the 1,000-hour salt spray test (ASTM B117).
How energy efficient is the Huada drying belt system?
Our drying belt is highly efficient, consuming only 8.2 kW·h/m² of energy, which is significantly lower than the industry standard of 12.5 kW·h/m².
