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

Automated Bulk Liquid Chemical Delivery System (BCDS) with PLC Controls for High-Volume Industrial Fluid Transport In high-volume manufacturing environments, such as semiconductor giga-fabs and EV battery plants, the Automated Bulk Liquid Chemical Delivery System (BCDS) serves as the high-capacity “circulatory system” of the facility. To manage the transport of thousands of liters of process chemicals daily, these systems rely on sophisticated PLC (Programmable Logic Controller) controls to ensure both precision and safety. The integration of PLC automation allows for a “set-and-forget” operational model. The system continuously monitors flow rates, line pressures, and tank levels, adjusting pump speeds in real-time to maintain a steady, pulse-free supply to point-of-use modules. This automation is critical for high-volume transport, as it eliminates the variability and contamination risks associated with manual handling. Safety is deeply embedded into the PLC logic. Jewellok-engineered systems feature automated leak detection and emergency shut-off protocols that can isolate a section of the manifold in milliseconds. Furthermore, the PLC manages Nitrogen (N2) blanketing for volatile solvents, maintaining an inert environment to prevent oxidation or combustion. By combining rugged 316L electropolished stainless steel with intelligent automation, an Automated BCDS provides the 99.9% uptime and ultra-high purity required for modern, large-scale industrial fluid management.

Jewellok’s CDS and CDM automate high-purity chemical handling. Use the CDS for bulk transport from storage to the facility via electropolished 316L piping. Use the CDM for precise blending and dilution at the point-of-use. Both systems ensure safety and purity through automated leak detection and non-contact level monitoring. These instructions outline the standard operation for Jewellok’s Chemical Delivery Systems (CDS) and Delivery Modules (CDM) to ensure safety and ultra-high purity (UHP) standards. 1. Bulk Supply and Delivery (CDS) The CDS manages the automated transport of bulk chemicals from storage to the facility. Operators must monitor the non-contact level sensors via the HMI panel to track real-time consumption. The system utilizes automated changeover protocols; when a supply barrel is empty, the system will switch sources to maintain a bubble-free flow. Ensure all 316L electropolished piping connections are inspected during scheduled maintenance to prevent particle contamination. 2. Mixing and Dispensing (CDM & VMB) The CDM handles precise blending and dilution at the point-of-use. Users must select the pre-programmed recipe control to automate the mixing of chemicals with DI water. Use the Valve Manifold Box (VMB) to isolate specific branch lines when servicing individual tools without halting the entire facility supply. 3. Safety and Waste Protocols All units feature automatic leak detection and secondary containment. If an alarm sounds, the system will automatically trigger a safety shut-off. For organic solvents, ensure nitrogen blanketing is active to prevent oxidation and fire hazards.
