A fluid coupling suitable for soft-starting high inertia machinery with reduced current demand, controlled acceleration, torque and motor overload protection.

Coupling Capacity
Maximum power @ 1500RPM - 600kW
Maximum speed - 3500RPM

Features & Benefits
High inertia-controlled torque to 700kW
Soft start - motor accelerates at reduced load
Reduced motor size - lower cost drive package
Overload protection - safeguards costly equipment
Dampens vibration, reducing mechanical stress - extends machine life
Delay fill version - extends acceleration time and further reduces start up torque
Automatically matches load and speed on multi drives
Energy saving through reduced current demand at start up
Coupling, brake and V pulley design types - design flexibility
