Integrated Bulk Chemical Delivery System and Automatic CDU Solutions for Safe Hazardous Chemical Fluid Handling

Integrated Bulk Chemical Delivery System and Automatic CDU Solutions for Safe Hazardous Chemical Fluid Handling

Safely managing hazardous chemicals requires a specialized, closed-loop approach that removes the human element from the danger zone. The Integrated Bulk Chemical Delivery System (BCDS) and Automatic CDU provide a unified solution designed specifically for the secure handling of toxic, corrosive, and flammable fluids.

By integrating bulk storage with automated dispensing, the system creates a seamless “drum-to-tool” flow. The BCDS handles the high-volume transport from secondary containment areas, while the Automatic CDU performs the precise point-of-use metering. This integration eliminates the need for manual pouring or open-container transfers, which are the primary causes of chemical spills and inhalation accidents in industrial settings.

Safety is engineered into every component. The system utilizes double-contained piping and air-operated valves to ensure that even a primary line failure is contained. Integrated sensors provide 24/7 monitoring, with automated emergency shut-offs that trigger instantly upon detecting a leak or pressure drop. For facilities handling hazardous etchants or solvents, this integrated solution is the most effective way to ensure regulatory compliance, protect personnel, and maintain an environmentally responsible production floor.

chemical delivery module (cdm) and chemical delivery system (cds)

Shenzhen Jewellok Technology Co., Ltd. is a premier manufacturer specializing in ultra-high purity (UHP) fluid control and chemical delivery solutions. We serve as the backbone for high-tech industries, providing the “circulatory systems” required for semiconductor fabrication, photovoltaic production, EV battery manufacturing, and pharmaceutical processing.

Our Core Expertise

We specialize in the design, engineering, and integration of automated systems that handle hazardous and ultrapure media. Our product portfolio is anchored by two flagship solutions:

Bulk Chemical Delivery Systems (BCDS): Engineered for large-scale, continuous transport of chemicals from bulk storage to the production floor. Our systems utilize 316L electropolished stainless steel and PFA-lined piping to maintain parts-per-trillion (PPT) purity levels.
Automatic Chemical Dispense Units (CDU): Point-of-use modules designed for surgical precision. These units automate the blending, dilution, and dispensing of critical fluids with a delivery accuracy of ±1%.

Engineering Excellence & Safety

At Jewellok, we prioritize contamination control and operational safety. Our systems feature:

Ultrapure Components: Surfaces finished to 5Ra to eliminate particle shedding.
Advanced Automation: PLC-based control with 3D HMI interfaces for real-time monitoring of flow, pressure, and tank levels.
Multi-Layered Safety: Integrated nitrogen blanketing, secondary containment, and millisecond-response leak detection to ensure SEMI S2 compliance and 24/7 uptime.

Our Mission

Jewellok is committed to helping global manufacturers increase wafer yields, reduce chemical waste, and eliminate human exposure to hazardous materials. By bridging the gap between bulk storage and precision dispensing, we provide the stability and purity essential for next-generation sub-micron manufacturing.

For technical consultations or custom UHP infrastructure projects, Jewellok Technology delivers the precision your process demands.
