Advanced Dry Air Technology, Safeguarding Transformers with Continuous Low Dew Point Air

REXON DAG Transformer Dry Air Generator is designed to provide a continuous supply of clean and dry air during the installation, maintenance, and reconditioning of power transformers, reactors, and other large electrical equipment.

During transformer maintenance, dry air helps prevent moisture and humidity from entering the equipment, protecting internal insulation and maintaining reliable electrical performance. It also provides a safer working environment for maintenance personnel working inside electrical equipment.

Compared with bottled dry gas, the DAG system provides a more convenient, economical, and reliable on-site dry air supply, eliminating the need for frequent gas cylinder replacement and transportation.

The system is especially useful when transformer oil purification and maintenance are carried out in rainy or humid environments. By supplying dry air to the equipment enclosure, it helps reduce moisture ingress and supports better insulation performance of the transformer and insulating oil.
