• Dry Air Generator for Transformer Maintenance

Dry Air Generator

KLEANOIL Dry Air Generator can provide air drying circulation inside transformer, replacing the traditional hot oil circulation method. It is suitable for the supply of dry air during the overhaul of large-scale power transformers. The dry air can ensure that the internal insulation of the power equipment will not be affected by moisture, and maintenance workers will not suffer from oxygen deficiency when working inside the equipment. It is safer, more reliable, economical, and convenient than using nitrogen. With the help of dry air generator, transformer overhaul can be performed during day and night, regardless the weather condition. The air drying system also shorten the maintenance schedule, improve the quality of inspection results.
