Air Dry GeneratorIt is widely used to supply dry air during the maintenance of large power equipment such as transformers and reactors. The provided dry air ensures that the internal insulation of the power equipment does not become damp, and maintenance personnel will not suffer from hypoxia when working inside the equipment. It is safer, more reliable, more economical, and more convenient than using nitrogen.
Working Principle:
Atmospheric air enters the air storage tank through the air compressor. Most of the moisture is compressed and liquefied, then discharged through the drain valve, achieving the first drying; then it enters the refrigerated dryer, where water vapor condenses into water, achieving the second drying; then it enters the adsorption dryer for the third drying, where the remaining trace moisture is adsorbed, and finally, it passes through a high-precision air filter and is delivered to the equipment requiring dry gas.
When using Air Dry Generator for equipment maintenance, it is not affected by changes in external climate conditions, especially for overnight operations. Simply seal the flanges and fill with dry air at 0.1~0.3Mpa, and transformers, reactors, etc., will not become damp without oil injection. This reduces the daily workload of oil extraction and injection, achieving the effect of shortening maintenance time and improving maintenance quality.
When using the Air Dry Generator for power equipment installation and maintenance, it is not affected by changes in external climate conditions, especially for overnight operations. Simply seal the flanges and fill with dry air to 0.02-0.03Mpa, without the need for oil injection, nitrogen supplementation, or vacuum pumping. Transformers, reactors, and other power equipment will not become damp, greatly reducing workload and achieving the effect of shortening the construction period and improving installation and maintenance quality. The Air Dry Generator is also suitable for air drying and circulation drying in warehouses, packaging, electronics, pharmaceuticals, and other industries, as well as for drying nitrogen, generator hydrogen, and SF6 equipment. It replaces traditional drying methods, is efficient, economical, safe, and environmentally friendly, integrating air compression, cold drying, and adsorption, and can be moved freely.
