Power Density Control System

The Corotec Power Density Control System. Your full-time quality control expert. Consistent Corona Treating Levels Regardless of Changes in the Line Speed, Web Width, or Materials.

Our Power Density Control System should not be confused with simple proportional speed control systems that are only able to compensate for changes in line speed. This system eliminates the need for complex graphics and charts when new materials are set up, or widths and line speeds are changed. It is only necessary for the operator to dial in the web width and the power density requirement for the material and treatment level desired, since speed feedback is automatically provided via the on-line tachometer supplied with the system. Our Power Density Control will then automatically adjust the output of the power supply to deliver the treatment level desired.

The treatment level attained on any given material is a function of energy applied per unit area, and it is commonly referred to as the power density requirement in watts per square foot per minute. Once a power density requirement is established for a particular material and treatment level, the same treatment level will always result as long as the power density is held constant, which is exactly how our Power Density Control System functions.
