High Voltage VFD Industrial Applications

Smelting Industry：In the metallurgical industry, variable frequency drives (VFDs) are employed to drive high-power, high-flowrate equipment. The application of VFDs further enhances operational stability. Typical applications:Slurry pumps, induced draft fans, descaling pumps, ventilation fans, dust removal fans, centrifugal feed pumps, blast furnace blowers, etc.

Petroleum industry：Typical applications: Water injection pumps, ID fans, squeeze pumps, ESPs, main pipeline pumps, gas compression pumps, boiler feed water pumps, etc. For the petrochemical industry, our VFDs deliver seamless integration into pumping station control systems — no changes to existing motors or wiring required, perfectly suited for both new build and upgrade projects.

Cement industry：Typical applications:Raw material mill fans, dust removal fans, preheating fans, coal mill fans, grinders, rotary kilns, high-temperature fans, etc.With a modular design, variable frequency drives (VFDs) simplify installation, commissioning and maintenance in the cement industry.Their performance has been proven to be highly reliable.

Electricity industry：Typical applications: Feed water pumps, primary air fans, forced draft fans, exhaust fans, ash slurry pumps, circulating pumps, booster pumps, condensate pumps, slurry pumps, etc.Traditional control methods are not only inefficient, but also extremely cumbersome to maintain. Variable frequency drives (VFDs) deliver more reliable, more accurate and more efficient direct-drive speed regulation control.

Non-ferrous Metals Industry：Typical applications: ID fans, mother liquor pumps, seed pumps, underflow pumps, digestion pumps, feed pumps, etc.The variable frequency drive (VFD) adopts power unit series multi-level technology, which meets the needs of load speed regulation, energy saving and production process optimization.

The coal industry：Typical applications: Belt conveyors (including multi-motor drive for a single belt), agitators/grinders, various slurry pumps, water pumps, all types of fans, compressors, etc.In large-scale conveyor applications, precise torque control and automatic load balancing in multi-motor control are critical. Variable frequency drives (VFDs) perfectly address these requirements.
