GF-100
100m3/h Mobile Transformer Dry Air Machine
- YUNENG GF-100 series mobile transformer dry air machine provides completely dry air for transformer maintenance.
- Dry air maintains good insulation of transformers, reactors, and other power facilities.
- It provides high-purity dry air with a dew point of up to -40°C to -70°C for installing and maintaining large power devices such as reactors and transformers.
The GF100 is a high-performance, low dew point -70°C dry air generator for medium oil-immersed transformers, providing continuous high-purity dry air to remove moisture and extend equipment life.
With stable operation, it adapts to various substation environments, meeting medium-scale transformer drying needs efficiently.
