AD Air Dryer is designed to provide high-purity dry air with dew point as low as -55 ° C to -70 ° C for electric power equipment such as High voltage transformers, ultra-high voltage transformers, and electric reactors during installation and maintenance. Removes moisture and particulates from the air. It can replace traditional drying methods such as hot oil circulation, nitrogen supplement and vacuum. It is more efficient, economical, safe and environmentally friendly. When using Air dryer for equipment maintenance, they are not affected by changes in external weather conditions, especially overnight operations, Just seal the flanges everywhere and fill with dry air 0.02Mpa-0.03MPa, no need for oil injection. electric equipment will not get wet, reducing the daily pumping and oiling workload, to achieve the effect of shortening the maintenance period and improving the quality of maintenance. during the oil filtration process, the tank and oil of the oil injection equipment can be aerated and dried to improve the oil filtration efficiency. When it is idle, it can be used as indoor air conditioning on the construction site.


 Using rapid regeneration technology, qualified dry air can be provided after 5 minutes of operation.

 the air dew point of the finished product is low. the core index of measurement is the gas supply dew point. the lower the dew point, the drier the air. Low dew point dry air will absorb the moisture in the transformer to improve the insulation performance of the transformer. Compression drying, freeze drying and adsorption drying are integrated into one machine, and a multistage filtration system is adopted.

 Efficient filtration system. Adopting "gradual density" filtration technology, the highest filtration accuracy is 0.01μm, and the solid particle rejection rate is as high as 99.99%. the filtration accuracy of the primary filter is 1 μm, the over-accuracy of the secondary filter is 0.1 μm, and the filtration accuracy of the fine filter is 0.01 μm.

 the adsorbent of the air dryer generator adopts a fully automatic regeneration method without thermal pressure difference, without manual baking of the adsorbent.

 "One-click control" technology. the air dryer uses a PLC intelligent controller. the device can be started by simply pressing the "Start" key. the device runs fully automatically, minimizing manual operation errors.
