Organic Chemical Automatic Liquid Supply System Chemical Delivery And Waste Collection Systems CDS And CDM

Shenzhen Jewellok Technology Co., Ltd. provides advanced ultra-high purity (UHP) chemical handling solutions, including chemical delivery module (CDM) and chemical delivery system (CDS). 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.

Fluid Chemical Delivery Module And Chemical Delivery System

chemical delivery module (CDM) and chemical delivery system (CDS)

In modern semiconductor and chemical manufacturing, handling organic solvents requires a closed-loop approach that prioritizes safety, purity, and environmental responsibility. An Integrated Organic Chemical Automatic Liquid Supply System manages the entire lifecycle of a chemical, from initial delivery to final waste recovery.

Automatic Liquid Supply and Delivery (CDS)

The supply side of the system is designed to transport organic chemicals—such as photoresists, thinners, and cleaning solvents—from bulk storage tanks or drums to the production line. To prevent fire hazards common with organic materials, these systems often use explosion-proof components and nitrogen blanketing to displace oxygen.

The delivery modules utilize UHP (Ultra-High Purity) piping, typically made of PFA or electropolished stainless steel, to ensure zero metallic contamination. High-precision sensors and non-contact level monitors track chemical usage in real-time, triggering automatic changeovers between supply barrels to ensure the manufacturing process never runs dry.

Chemical Delivery/Dilution (CDM)

Before reaching the wafer, many organic chemicals require precise mixing. The CDM automates this by blending concentrated solvents with DI water or other additives. By using automated recipe control, the system eliminates human error, ensuring that every batch meets the exact concentration required for consistent etching or stripping results.

Waste Collection Systems

The process concludes with the Waste Collection System. Once chemicals are used, they are automatically diverted into dedicated waste streams based on their composition. This segregation is critical for preventing dangerous chemical reactions and facilitating solvent recovery. Automated pumps move the waste into specialized storage tanks equipped with leak detection and vapor recovery units, ensuring that no toxic fumes escape into the facility.

By integrating supply, delivery, and waste collection into a single automated loop, manufacturers achieve a “hands-off” environment that maximizes operator safety while maintaining the extreme purity levels demanded by the industry.
