1 Power & Drive Turns electrical power into mechanical drive: compressor motors, starters, soft-starts, belts, pulleys, and other driven-load hardware. ▸
Role in the system
Power & Drive
Motors and the gear that starts, protects, and couples compressor and pump loads.
Choose by fit
Electric Motor → Magnetic Starter → Soft Starter → Motor Pulley → V-Belt →
2 Control & Logic Decides when and how the drive runs: alternation, sequencing, relay logic, and lead-lag duty rotation. ▸
Role in the system
Control & Logic
Relays and logic that stage paired compressors, pumps, and redundant utility packages.
Product type
Alternating Relay →
3 Sensing & Feedback Reports what the system is doing: pressure switches and electrical feedback that close the compressor or machine loop. ▸
Role in the system
Sensing & Feedback
Pressure switches that start and stop compressors or feed status into the control panel.
