Filters and Breathing Valves Successfully Delivered for Hualu Engineering’s 80,000-ton Electronic-Grade Granular Polysilicon Industrial Upgrading Project

The supporting filters and breathing valves for Hualu Engineering’s 80,000-ton technical renovation project of electronic-grade granular polysilicon were fully delivered on schedule.
Complying with stringent process specifications featuring ultra-high cleanliness and closed explosion-proof requirements for electronic-grade raw materials, our equipment adopts refined fluid purification and safety pressure stabilization core technologies to precisely control material impurities and balance sealed tank operating conditions. It ensures polysilicon products meet standard grades from the source of the process and establishes a solid safety barrier for production lines.
