Overview

CerAnode’s ASAI Air-Cooled Rectifiers are compact, efficient DC power supplies designed to deliver steady current for impressed-current cathodic protection (ICCP) systems. These units convert AC mains to adjustable DC output and utilize natural or forced air convection to dissipate heat, making them ideal for small to moderate cathodic protection (CP) installations in non-harsh environments.

Key Benefits
  • Extended service life (15-30+ years)
  • Higher current output capability
  • Adaptable protection levels
  • Effective for large structures
  • Suitable for high-resistivity environments
  • Remote monitoring capabilities
Common Applications
  • Pipeline protection (oil, gas, water)
  • Marine structures and vessels
  • Underground storage tanks
  • Reinforced concrete structures
  • Industrial water systems
  • Well casings and offshore platforms

Power Sources & CP Control Equipment

Air-cooled rectifiers (ASAI)

CerAnode’s ASAI Air-Cooled Rectifiers are compact, efficient DC power supplies designed to deliver steady current for impressed-current cathodic protection (ICCP) systems. These units convert AC mains to adjustable DC output and utilize natural or forced air convection to dissipate heat, making them ideal for small to moderate cathodic protection (CP)

Lifespan: 25-30+ years

Environments: Soil, freshwater, seawater

Oil-Cooled Rectifiers (OSOI/OSXI)

CerAnode’s OSOI / OSXI Oil-Cooled Rectifiers are high-capacity transformer-rectifier units built for impressed-current cathodic protection (ICCP) installations that demand maximum reliability under harsh environmental conditions, including offshore, coastal, high-humidity, or dusty industrial sites. By immersing the transformer and rectifier stack in dielectric oil, these units deliver superior cooling, long service life, and stable DC output, even under continuous full-load operation.

Lifespan: 25-30+ years

Environments: Soil, freshwater, seawater

Multi-Channel Rectifiers (REC)

CerAnode’s REC Multi-Channel Rectifier is a versatile DC power supply designed to run multiple cathodic protection (CP) circuits from a single unit. Each channel can be independently adjusted to supply DC current to separate anode beds or protected structures, making the REC ideal for complex pipeline networks, multi-tank farms, or distributed CP systems.

Lifespan: 25-30+ years

Environments: Soil, freshwater, seawater
