GF Transformer Dry Air Generator
- Our GF transformer dry air generator is mainly used to quickly and effectively provide dry air for transformers and other industrial equipment. It uses an air compression system, refrigerated air drying system, adsorption drying system, air purification system and PLC control system.
- This air drying equipment and purification system use a low-pressure oil-free compression system and low-temperature condensed moisture removal technology, which can solve the problems of dirty oil caused by air, steam and dust.
- Our dry air machine has the characteristics of small size, lightweight, easy installation and operation, energy-saving and high reliability. This machine has a series of instant display instruments such as power supply voltage, outlet pressure, outlet dew point, outlet temperature, absorption stroke, etc., which is very convenient to manage.

Advantages of Dry Air Generator in the Electric Power Industry
- The dry air generator for transformer can show its unique advantages for large transformers and reactors in the power system.
- When the transformer is shipped from the factory, heavier insulating oil is pumped out and replaced with very light dry air, which reduces the transportation cost of large transformers.
- Due to a long time for overhaul and accident repair of a large transformer, sometimes more than half a month, if there is no absolutely dry air to fill the transformer around the clock, the transformer body will be seriously damp, and it will be seriously corroded. The insulation performance will be destroyed.
- The dry air generator manufactured by our Oil Purifier can ensure that the internal insulation of the transformer will not get wet during the maintenance process, and the maintenance personnel will not suffocate due to lack of oxygen when working inside the equipment. It is not affected by external climate change, avoiding the traditional transformer oil thermal cycle drying method, which can ensure the improvement of oil insulation performance and the reduction of moisture, and also ensure the personal safety of maintenance personnel.
Application of Dry Air Generator
- Dry Air Generator For Transformer is suitable for supplying dry air that keeps the power equipment’ inner parts from moisture in the maintenance of the transformer, reactor and other large power equipment.
- This machine can ensure that the maintenance staff will not be short of oxygen when working inside of the equipment. It is more reliable economical convenient and safer than nitrogen. Therefore, it can shorten the maintenance period and improve the efficiency of maintenance quality.
Why We Need Dry Air Generator?
- Dry air generator for a transformer is used to remove moisture from the air. It is suitable for air drying of transformers. In the maintenance of power transformers, instrument transformers and other large power equipment, the dry air generator can keep the interior of the power equipment from moisture and prevent potential safety hazards. These dry air machines are specifically designed for transformer applications. It adopts an advanced and reliable microprogram control unit, which has the characteristics of automatic timing and automatic switching. Dry air generators remove particles up to 0.01 microns.
- Chongqing Yuneng, as a reliable transformer air dryer supplier in China, cooperates with a famous local university (Chongqing University) to develop an integrated dry air generator. Customers can choose PLC to automatically check parameters. Our air compressors can work continuously and reliably, without the need for workers to supervise, and can automatically alarm if a fault is diagnosed. The oil content of the air outlet of the machine is as low as 0.01PPM.
