EPM – Protection against Over Pressure for Extrusion Lines

Throughout the world, the requirements on plastics and rubber machines with regard to safety protection against over pressure are increasing.

With the Gneuss safety system EPM, the use of stretch bolts, fail safe components, rupture discs or movement sensors can be avoided.

Extruders, melt pumps or components which are under pressure can be protected against excess pressure by the EPM safety system, with a duplicated and monitored pressure measurement. The safety-relevant components of the monitoring system conform to EN ISO 13849 -1, with a performance level of ´c´.

In addition to the pressure monitoring / cut out function, the pressure monitoring system contains safety features such as emergency stop or protection monitoring.
