GF-100 Series Mobile Type Transformer Dry Air Machine


YUNENG GF-100 Series Mobile Type Transformer Dry Air Machine appropriates for providing completely dry air for transformer maintenance. Dry air can maintain good insulation of transformer, reactor as well as other power facilities. It is developed to provide high-purity dry air with a dew point up to -40 C ~ -70 C for installment and upkeep of large power devices such as reactors as well as transformers.

Application and Function of YUNENG GF-100 Series Mobile Type Transformer Dry Air Machine:

  • GF-100 Series transformer air dryer is designed to provide high-purity dry air with dew point up to -40C~-70C for installation and maintenance of large power equipment such as transformers and reactors.
  • It can replace traditional hot oil circulation, nitrogen filling, vacuum drying, etc. Way, and more efficient, economical, safe, and environmentally friendly. Instead of the traditional drying method, it is efficient, economical, safe, and environmentally friendly.
  • It integrates air compression, cold drying, and adsorption and can move freely.

Working Principles of Transformer Air Dryer:


The GF-100 Series transformer air drying machine mainly consists of a gas source system, a gas compression system, a freeze-drying system, an adsorption drying system, and an electric control system. The mobile high-purity dry air generating device is composed of five parts. Air source system composition: It consists of an air dust filter, oil-free air pump (or screw-type oil-free air compressor), radiator (air-cooled), gas-water separator and filter, and outputs clean and oil-free gas. The atmosphere enters the gas storage tank through the air compressor, most of the water is compressed and liquefied and discharged through the drain valve, and the air is once dried; then enters the refrigerating dryer, the water vapor is condensed into water, and the air is dried for the second time; then enters the adsorption The dryer is dried for the third time, and the remaining traces of water are adsorbed, and then transported through a high-precision air filter to the equipment to be dried.

Advantages of Transformer Dry Air Machine:

  1. The transformer air drying machine is suitable for supplying dry air for transformer maintenance. Dry air can keep good insulation of transformer, reactor and other power facilities.
  2. Meanwhile, operators will not be short of oxygen to maintain inside.
  3. Dry Air Generator for Transformers is safer, cheaper, more reliable & convenient than using nitrogen.
  4. With a transformer air dryer for transformers maintenance, you can save time for maintenance and get good efficiency.
  5. Transformer air drying for transformer maintenance Parameter.
