8 top-level parts · 31 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Variable Frequency Drive 4 parts | 1× | PWM inverter that modulates compressor speed 25–100 percent to track vapor make. |
| 2 | Unit Controller 3 parts | 1× | PLC running the pressure-control loop, permissives, and shutdown logic. |
| 3 | Panel HMI 2 parts | 1× | Local display showing suction pressure, speed, temperatures, and alarm history. |
| 4 | Power Supply | 1× | Unit that converts mains or battery input into the regulated DC voltages a machine's electronics and actuators need. |
| 5 | Relay | 6× | Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch. |
| 6 | Wire Bundle | 1× | Group of insulated conductors cut to length, terminated, and bound together to carry power and signals between the assemblies of a machine. |
| 7 | Connector | 8× | Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering. |
| 8 | Sheet Metal Panel | 1× | NEMA 4 enclosure |
