VFD

Delta Variable Frequency Drives match motor speed to actual process demand instead of running motors at full speed continuously, cutting energy use by 20-50% on variable-torque loads like pumps, fans, blowers, compressors, and conveyors. VFDs add soft-start, precise torque and speed control, and reduced mechanical wear compared to direct-on-line or soft-starter setups, and integrate with HVAC, water supply, and production-line automation.
