PP Chemical Delivery Unit
The Chemical Delivery Unit (CDU) offers a cost-effective, automated solution for transferring chemicals from the drum to the day tank and then to the Fab, with an onboard PLC/HMI for easy control and set point adjustments. It also includes a Diaphragm Pump for smooth transfer, an alarm system for drum replacement, and a Levitronix Centrifugal Pump with sensors and safety measures to ensure controlled delivery and prevent spills or air entry into the fabrication area.
