Our dry air generator for transformer 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.

It 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.

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 Spera 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.
