Oil Immersed Rectifiers

PRODUCT ORDERING CODES









Enclosed in a rugged nonclassified or explosion-proof tank, these oil-immersed durable cathodic protection rectifiers are constructed with lifting eyes, with a lockable, hinged top, and with fins for added cooling and strength. Separate transformer and stack rack assemblies are provided for easy removal and servicing. The construction of the explosion proof housing option is classified for use in areas with flammable vapors. Single or three-phase input available.  Cooled by oil and by radiating fins, your corrosion prevention rectifier will be protected by thermal or magnetic circuit breakers.  Custom oil cooled rectifiers are classified by enclosure:

  • Nonclassified (Non Explosion Proof Enclosure)
  • Explosion Proof Enclosure for use in Class I, II & III, Division 1 and Class1, Zone 0 & 1 Hazardous (Classified) Locations, as classified by ANSI/ISA, IECEx and ATEX.
