CASE ANALYSIS
Scenario
An injection molding machine requires a stable supply of cooling water to reject process heat and maintain mold temperature. A closed-loop recirculation circuit with flow control ensures consistent cooling capacity.
Key decisions
- Used a centrifugal circulation pump and buffer tank for closed-loop recirculation rather than once-through cooling.
- Included a flow transmitter (FT-101) and flow indicating controller (FIC-101) to regulate supply flow to the molding machine via a pneumatically actuated control valve.
- Placed a Y-strainer and shell-and-tube heat exchanger upstream of the machine to remove particulates and reject heat to an external utility.
When to reuse this
Reusable for any industrial closed-loop cooling water recirculation system where flow control and heat rejection are required, such as injection molding, extrusion, or hydraulic cooling circuits.
