ALCO Rectifier Air Cooled Standard Line
ALCO Rectifier Standard Line Advantages
The “Standard Line” air cooled, cathodic protection rectifiers are recognized as industry leading in quality, workmanship and service life. Many years of field-proven service prove their superior design. Conservative equipment ratings, controlled manufacturing techniques, plus many extra features ensure long and trouble-free operation.
ALCO Rectifier Standard Line Applications
Typical cathodic protection applications for the air cooled rectifier line include pipelines, tank farms, storage fields, and other non-hazardous locations where continuous duty, DC power is required.
