This device is mainly used in power systems, warehouses, packaging, electronics and other industries for air supply drying and circulating drying, replacing the traditional hot oil circulation drying method for transformers. It is suitable for supplying dry air during the maintenance of large power equipment such as transformers and reactors. The provided dry air ensures that the internal insulation of power equipment is not affected by moisture, and maintenance personnel will not suffer from oxygen deficiency when working inside the equipment. It is safer, more reliable, economical, and convenient than using nitrogen. When using the dry air generator for equipment maintenance, it is not affected by changes in external weather conditions, especially for overnight operations. Simply seal the flanges and fill with dry air at 0.1-0.3MPa, without the need for oil injection. Transformers and reactors will not be affected by moisture, reducing the workload of daily oil pumping and injection, achieving the effect of shortening maintenance cycles and improving maintenance quality. During oil filtration, the equipment box and oil can be filled with dry air to improve filtration efficiency (more than double). When filtering oil on rainy days, it ensures the improvement of oil insulation and reduction of moisture. When idle, it can be used as an indoor air conditioner at the construction site.

Product Principle:
ZGF series dry air generator mainly consists of air compressor, refrigerator, adsorber, three-stage precision dry air filter, electric control system, pressure reducing valve, dew point meter and other parts. The compressed air enters the pre-cooler for cooling, then enters the centrifugal dewatering filter for the first water-gas separation, then enters the refrigerator for deep condensation dewatering, most of the water vapor is condensed into water, the air undergoes the second coalescing dewatering filter, then enters the renewable dry air filter to adsorb the remaining water vapor. The dry air after adsorption and dewatering enters the 0.01μm high-precision filter to remove particles, and then is transported to the equipment requiring dry gas through the pressure stabilizing valve, to ensure that the transformer will not reduce insulation strength due to impurities. The dew point detector detects the air dew point, and alarms when the air is unqualified.
