The PureTech Dry Air Generator (Model DAG) is also called as Air Drying System and Air Dryer, it is used to supply dry and purified air for transformers and other electrical equipment. It can quickly and effectively supply dry and clean air to the container or interior zone. This air drying equipment is suitable for supplying dry 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.
Dry Air Generator 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. Compared with the traditional nitrogen-filling way, dry air generator is more reliable, safe and economic.
Dry Air Generator will shorten the maintenance period and greatly improve the efficiency of maintenance quality.
• 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.
