SDS20 Transformer Oil Dehydration System The SDS20 Transformer Oil Dehydration System utilizes Velcon's Superdri technology to remove dissolved water from transformer oil. The dual stage unit processes oil to reach moisture levels of 10 parts per million of dissolved water or less in a single pass. The SDS20 can dramatically reduce oil filling costs by eliminating the need for costly heat and vacuum units to dehydrate transformer oil. The system is designed with all the necessary features required for critical transformer filling operations. These features help reduce downtime and eliminate added cost from sampling error, or from improper use of filter cartridges.

APPLICATIONS

The SDS20 System with Superdri cartridges can be used for oil processing situations where removal of dissolved water in insulating oil is necessary.

  • Use the SDS20 System to process oil used to fill new distribution and EHV transformers. Avoids the need for heat and vacuum systems to dry the oil
  • Filter and dehydrate transformer oil used to fill existing transformers after repair or service
  • Use the SDS20 System to enable oil to meet moisture critical ASTM D-1816 dielectric strength requirements
  • Purify oil used for circuit breakers and other high voltage apparatus that is sensitive to dissolved water
  • The SDS20 can be fitted with standard Aquacon filters for routine oil maintenance work
