Custom Chemical Delivery System (CDS) Engineering for Hazardous Etchants and Volatile Organic Solvent Distribution Systems
When handling hazardous etchants and volatile organic solvents, safety and material compatibility are the non-negotiable foundations of facility engineering. A Custom Chemical Delivery System (CDS) is specifically designed to manage these high-risk fluids, ensuring they are transported from bulk storage to production tools without compromising personnel safety or environmental integrity.

Materials & contamination control
For aggressive acids such as Hydrofluoric (HF), custom engineering commonly uses PFA-lined piping or high-grade 316L electropolished stainless steel to prevent corrosion and metallic ion leaching. Systems are configured for ultra-high purity (parts-per-trillion) requirements using 316L electropolished stainless steel with a 5Ra surface finish to minimize particle shedding and ensure chemical inertness throughout fluid paths.

Safety, automation & containment
The intelligence of the custom Jewellok CDS is in its automated safety architecture. Every system includes secondary containment (pipe-within-a-pipe or cabinet-within-a-cabinet) coupled with high-sensitivity leak detection. Managed by a centralized PLC (Programmable Logic Controller), the system can trigger immediate automated shutdown of pneumatic valves on leak or pressure anomaly. Additional measures include nitrogen blanketing for volatile solvents, automated leak detection, explosion-proof cabinet options and multi-tiered interlocks to protect personnel and product yield.
