Vertical Laminar Flow Workstation (VLF) With Chemical Concentration Monitor
While Shenzhen Jewellok Technology is primarily known for ultra-high purity (UHP) gas and chemical delivery systems (such as gas cabinets and valve manifold boxes), it also provides specialized laboratory and semiconductor processing infrastructure. A Jewellok Vertical Laminar Flow (VLF) Workstation integrated with a Chemical Concentration Monitor is typically used in wet processing environments where precise chemical levels and a particle-free environment are critical.

- 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%.
- 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.
