Modular Anode Control System

EcoDC MACS is an innovative electrocoating plant design. A modular rectifier design permits flexible activation of individual anodes and large anode groups. This results in an optimized voltage profile that tracks the car body’s movement through the EC tank. “DC” stands for “direct current”; “MACS” is the acronym for “Modular Anode Control System.”

EcoDC MACS reduces production failures. If anodes or anode groups should fail, the flexible control system permits the adjacent modules to compensate for the malfunction in the coating process. This ensures uniform coating quality.

EcoDC MACS is based on IGBT technology. This achieves a very low residual ripple value of less than 2% over the entire current and voltage range. The result is a more uniform coating with lower surface roughness values. The efficiency value of more than 96% saves energy. Simultaneously, it is no longer necessary to maintain a supply of standby rectifiers.

Your benefits:

  • High coating quality
  • Greater energy efficiency
  • Small footprint
  • Modular design
  • Greater availability
  • No standby rectifiers required
