Ultra-High Purity Bulk Liquid Chemical Delivery System (BCDS) for Maintaining Parts-Per-Trillion Purity in Manufacturing

Ultra-High Purity Bulk Liquid Chemical Delivery System (BCDS) for Maintaining Parts-Per-Trillion Purity in Manufacturing

In the world of advanced semiconductor and photovoltaic manufacturing, the journey of a process chemical begins with the Ultra-High Purity Bulk Liquid Chemical Delivery System (BCDS). This system serves as the primary “artery” of a facility, responsible for transporting large volumes of acids, solvents, and bases from bulk storage to the production floor without introducing a single microscopic contaminant.

To achieve and maintain Parts-Per-Trillion (ppt) purity, the BCDS is engineered using 316L electropolished stainless steel. This specialized material features a mirror-like 5Ra internal finish, which eliminates the microscopic “peaks and valleys” where particles could be trapped or metallic ions could leach into the fluid. Every weld and connection is designed to be “dead-space free,” ensuring that chemicals do not stagnate and degrade.

Managed by sophisticated PLC-controlled automation, a Jewellok-engineered BCDS provides a continuous, pulse-free flow. Safety is non-negotiable; the system integrates Nitrogen (N2) blanketing to prevent oxidation of sensitive chemicals and uses secondary containment with high-sensitivity leak detection. By providing a “zero-contamination” bridge between bulk supply and point-of-use modules, the BCDS ensures that the high-tech manufacturing process maintains 99.9% uptime and the highest possible product yield.

Chemical automatic liquid supply equipment

Shenzhen Jewellok Technology Co., Ltd. is a premier global manufacturer specializing in the engineering and production of Ultra-High Purity (UHP) gas and liquid chemical delivery systems. Headquartered in the high-tech hub of Shenzhen, China, we provide the mission-critical fluid infrastructure required for sub-micron semiconductor fabrication, photovoltaic energy, and advanced EV battery manufacturing.

At the core of our portfolio are the Chemical Delivery Module (CDM) and Chemical Delivery System (CDS). These systems are engineered to meet the industry’s most stringent parts-per-trillion (ppt) purity standards. While our bulk CDS solutions manage the large-scale distribution of process fluids, our CDMs provide precision, point-of-use blending and dilution. By utilizing 316L electropolished stainless steel with a 5Ra surface finish, we ensure zero-particle shedding and maximum chemical inertness across all fluid paths.

Jewellok distinguishes itself through a commitment to “Intelligence + Safety.” Our systems feature proprietary UHP diaphragm valves with metal-to-metal seals and advanced PLC-controlled automation. This integration allows for precise recipe management and predictive maintenance, which has been shown to reduce facility downtime by up to 30%. Furthermore, our hardware is built with multi-tiered safety protocols, including secondary containment, nitrogen blanketing, and automated leak detection to protect both your personnel and your product yield.

As a trusted partner to the world’s leading high-tech manufacturers, Jewellok provides more than just hardware; we provide the “circulatory system” of the modern smart factory. From initial design to installation and technical support, we ensure your facility operates with 99.9% uptime and absolute purity.
