Automated Bulk Liquid Chemical Delivery System (BCDS) with PLC Controls for High-Volume Industrial Fluid Transport

The Automated Bulk Chemical Delivery System (BCDS) provides high-capacity, continuous chemical supply for high-volume manufacturing environments such as semiconductor fabs and EV battery plants. The system transports large daily volumes of process chemicals and delivers a pulse-free supply to point-of-use modules through PLC-based automation and redundant pump architecture.

PLC Automation and Operational Control
The integrated PLC monitors flow rates, line pressures and tank levels and adjusts pump speeds in real time for stable delivery. The control strategy supports recipe-based dosing, automatic barrel changeover and touchscreen HMI for status, setpoints and alarm handling — reducing manual interventions and contamination risk.

Safety, Materials and Purity
Safety logic in the PLC includes automated leak detection, rapid emergency shut-off and manifold isolation. Nitrogen blanketing is controlled for volatile solvents. Wetted parts are electropolished 316L stainless steel and PFA where specified to meet ultra-high purity requirements.
