Air Cooled Standard Line

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.

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.
