APPLICATIONS

CRS rectifiers deliver precision DC, PP, and PPR power across the full spectrum of industrial surface treatment, electroplating, and electrochemical processes — engineered for the most demanding environments worldwide.

Aluminium hard anodizing application
ANODIZING

ALUMINIUM HARD ANODIZING

Electrochemical process growing a thick oxide layer on aluminum. PP and PPR waveforms reduce anodizing time by 30% and prevent film burning – compatible with alloys 2024, 7075, ADC12.

Aluminium electrolytic coloring application
ANODIZING

ALUMINIUM ELECTROLYTIC COLORING

Drives metal ions (tin, cobalt, nickel) into anodized pores using AC or DC waveforms. One CRS unit replaces separate DC and AC power supplies – sine wave 20-100 Hz for faster, more uniform coloring.
