PP Corrosion-Resistant Equipment
CDS Chemical Dispense System
Product Overview
A CDS (Chemical Dispense System) transfers chemicals automatically from bulk containers to the point of use at each process tool. Design centres on safety, cleanliness, stability, expandability and automation, with main and branch pressure drops and flows calculated from actual consumption.
Because the dispensed chemicals are volatile organic materials, the system is designed to explosion-proof standards and carries the dual protection of leak detection and a monitoring system.
Features & Specifications

►**Corrosion resistance**：resists strong acids, strong alkalis and chemical reagents; impact resistant
►**Customisation**：dimensions, sheet thickness, door count, hinge direction and viewing panels all designed to requirement
►**Common configurations**：Central chemical dispense system、PP transfer rollers、Distribution piping with safety and stability provisions
Detailed Description
Why the protection has to be dual
A dispense system moves strong acids and alkalis through piping that crosses the whole plant. When a single protection mechanism fails and there is no second, the result is a large-scale release. **Leak detection** handles the case where liquid has already escaped: sensors in trenches, tool bases and the bulk area trigger an EMO shutdown the moment liquid is present. **The monitoring system** handles the case where nothing has leaked yet but is about to: continuous watch on flow, pressure and level raises an alarm on an abnormal trend before a release occurs. The two detect at different moments and neither substitutes for the other. Leak detection alone can only limit damage after the fact; monitoring alone is powerless against a sudden pipe rupture.Selection References
