Liquid Bulk Chemical Delivery System with Automatic Chemical Dispense Unit (CDU) Featuring 316L Electropolished Stainless Steel Piping Components

Liquid Bulk Chemical Delivery System with Automatic Chemical Dispense Unit (CDU) Featuring 316L Electropolished Stainless Steel Piping Components

In high-tech manufacturing, the integrity of a Liquid Bulk Chemical Delivery System (BCDS) depends entirely on the quality of its internal surfaces. This system, paired with an Automatic Chemical Dispense Unit (CDU), utilizes 316L Electropolished (EP) Stainless Steel piping to create a near-perfect environment for transporting ultrapure fluids.

Standard stainless steel contains microscopic pits and ridges that can trap particles or react with aggressive chemicals. By using 316L EP components, the internal surface is smoothed to a mirror-like 5Ra finish. This process removes surface impurities and enhances the chromium-rich passive layer, providing superior corrosion resistance against solvents and high-purity chemicals.

When integrated with an Automatic CDU, this “ultra-smooth” infrastructure ensures that chemicals arrive at the point of use with zero added contaminants. The CDU precisely meters and blends these fluids using automated valves and sensors, maintaining the high yields required for semiconductor and pharmaceutical production. This combination of superior material science and advanced automation not only guarantees parts-per-trillion (PPT) purity but also extends the lifespan of the system by preventing chemical buildup and “dead zones” within the piping.

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.
