PREMIUM SERIES
DualZone Phase Converters
Twice the starting power. Maximum efficiency. Built for the toughest loads.
Available in 20 HP – 100 HP
What Makes DualZone Different?
The DualZone series uses a dual-motor design that delivers more starting torque and runs more efficiently than any single-motor converter on the market.
⚡
2x Starting Power
Dual-motor design delivers twice the starting torque of standard converters. Handles heavy inrush loads with ease — compressors, elevators, heavy CNC machines.
🔋
Energy Efficient
The secondary motor only activates during startup, then disengages. At idle, the DualZone uses less energy than a standard single-motor converter.
🎯
Balanced Voltage
Factory-calibrated for tight voltage balance across all three phases. Your sensitive equipment runs smoothly and safely.
