Application of Transformer Air Drying Machine

The PureTech Air Drying Machine (Model DAG) is also called as Dry Air Generator or Air Dryer, it is used to supply dry and clean air for power transformers and other electrical equipment.

It can supply dry and clean air to the container or interior zone quickly, continuously and effectively . This air drying machine is designed to supply drying air when engineers are working inside the transformers during installation and maintenance, so as to keep the inner components of transformers from the moisture,and meanwhile provide purified dry air for engineers, so the maintenance staff will not be short of oxygen when working inside.

Compared with the traditional way of "Nitrogen-Filling", Air Drying Machine is a safer, reliable and more economic equipment necessary for transformer maintenance. It will shorten the maintenance period and greatly improve the efficiency of maintenance quality.

Composition of Transformer Air Drying Machine

PureTech Air Drying Machine uses an air compression system, refrigerated air drying system, adsorption drying system, air purification system and PLC control system. With a unique design of "Double-Tank" , it can work continuously without stop, the two tanks will change automatically when the moisture reaches satuation, and start drying itself.

Features of Transformer Air Drying Machine

• Continuous and reliable working without supervision, multi protection devices are installed to ensure performance.

• Main components are from world famous brands to ensure the reliable quality.

• Advanced and reliable PLC control unit is integrated, which characterizes automatic timing, automatic switch of work.

• Operating parameters can be displayed and monitored on the screen of electrical control cabinet.

• Intelligent design makes operation much easier and safer.

* For outdoor use, waterproofing cover is recommended.
