The ITB intelligent maintenance-free dehumidifier consists of several parts including a silicone chamber, heating device, filtering device, and intelligent controller. Humid air enters the device through the metal filter screen at the bottom of the ITB maintenance-free dehumidifier, which filters dust, sand, and other particles from the air. The filtered air passes through the silicone chamber in the dehumidifier for dehydration, and the dehumidified air enters the transformer through the pipeline in the oil cushion.

The ITB intelligent maintenance-free dehumidifier is equipped with a temperature and humidity sensor to measure the humidity of the air entering the transformer. When the measured humidity exceeds the set value and the transformer is in exhalation mode, the heating element installed in the drying chamber will automatically dry the silicone particles. The water vapor generated during the silicone drying process condenses on the glass outer wall of the maintenance-free dehumidifier, and the condensate is discharged through the metal filter screen, which also helps to clean the metal filter screen.

The ITB intelligent maintenance-free dehumidifier can upload the device's operating status and the temperature and humidity data of the transformer breathing pipeline to the background monitoring system via communication protocol for real-time monitoring, data storage, analysis, and mining functions.

The ITB intelligent maintenance-free dehumidifier eliminates the need for silicone replacement and cleaning of the oil cup, reducing labor costs and avoiding safety hazards caused by blocked breathing passages. At the same time, the ITB intelligent maintenance-free dehumidifier can also upload the device's operating status and temperature and humidity data of the breathing passage to the computer monitoring system, making it particularly suitable for centralized control and unmanned operation modes in substations. It effectively improves the intelligence level of the equipment and is beneficial for the safe operation of transformers.
