Wuxi Zhanghua Pharm & Chem Equipment Co., Ltd. Equipment designed for the process requirements of electronic-grade production.

Founded in 1976, Wuxi Zhanghua has spent nearly five decades developing and manufacturing reaction, crystallization, filtration, and drying equipment.

Our Filtration-Washing-Drying “Three-in-One” equipment has been validated in the production of semiconductor materials, electronic-grade powders, high-purity precursors and other high-end applications.

Our equipment delivers the following capabilities:

· Fully sealed operation – Material is never exposed to the external environment, from feeding to discharging.

· Displacement washing + multi-stage counter-current washing – Metallic ion content reduced to ppb/ppt levels.

· Vacuum low-temperature drying – Protects heat-sensitive materials against oxidation and degradation.

· Integral helium leak testing – Standard at delivery, with leak rate controlled to the 10⁻⁷ Pa·m³/s scale.

· CIP/SIP capability – Meets clean-process production requirements.

· PLC/DCS full automation control – Enables comprehensive data recording and batch traceability.

· ATEX explosion-proof certification + solvent recovery system – Suitable for organic solvent systems and flammable materials.

Electronic-grade products require production equipment designed around tighter purity, sealing, and traceability controls.
