Advantages of YUNENG transformer drying system:

  1. YUNENG transformer drying system uses the screw compressor units from the leading air compressor manufacturing ATLAS COPCO.
  2. The low-speed centrifugal fan has a big capacity and low noise. The automatic computer controller ensures the compressor is running at the best performance.
  3. The cooling system adopts a highly efficient, fully enclosed air-cooled motor, level of protection grade IP54, insulation class F, can be maintained long-term trouble-free operation.
  4. The absorption dryer takes a regenerative dryer with low air consumption, low-pressure loss, a long service life desiccating agent, stable outlet pressure, and dew point.
  5. The air dryer for the transformer uses a programmable controller PLC for host control, and the text displayer monitors the operating status of the combination of the machine.
