The KX is a fluid coupling with a special patented circuit designed to start up large inertia machines driven by eletric motors. The circuit includes two internal tanks connected by a scoop. The scoop works like a differential pump transferring the fluid from one chamber to the other and finally into the coupling working circuit through external adjustable valves. This double passage allows a long starting time with very low starting torque and absorbed current by the electric motor, virtually isolating the effect of the inertia of driven machine.
The coupling can work using both oil and treated water as standard.
