VLT 4000 VT Series adjustable frequency drives are UL, cUL, and CE listed units specifically designed to meet the performance and reliability demands of variable torque applications.
Featuring built-in harmonic distortion protection, they are engineered to protect the drive, motor, and process equipment. They eliminate control valves and problematic pressure storage tanks and reduce energy consumption maintenance and pump noise.
The units can optimize flow, level, and pressure process control and are suitable for controlling multiple parallel-coupled pumps and blowers.
