In 1968, a small company in Fenton, Missouri, just outside of St. Louis called Magnetic Power Systems pioneered the use of magnetic particle torque control technology for industrial applications. In fact, our father Ed Grosel, sold clutches in the early days with then President, Gerald Eddens.  We have supplied MAGPOWR’s controls, sensors, brakes and clutches since the early days.  Our tension control expertise has been solving web handling issues for over 50 years.
