DH-C10 Intelligent Compressor Dehumidifier

DH-C10 Intelligent Compressor Dehumidifier

DH-C10 Intelligent compressor dehumidifier uses compressor refrigeration technology to make the moisture air inside the electric box condense into water on the surface of the condensation plate of the dehumidifier and then discharge it out of the cabinet, quickly reducing the humidity inside the cabinet.

DH-C10 Intelligent compressor dehumidifier is equipped with an intelligent control module and adopts anti-interference technology. The double-row digital tube displays the measured value and the set value at the same time, and alternately displays the current temperature and humidity, and realizes the automatic control function of humidity.

Dehumidification principle

The intelligent compressor dehumidifiers operate based on the vapor-compression refrigeration principle. Humid air is drawn into the unit and passes through the evaporator, where moisture condenses into water and is discharged through the drainage tube. The air reheated by the condenser and released back into the environment, enabling continuous dehumidification.

The refrigerant circulates through the compressor, condenser, expansion device, and evaporator to complete the refrigeration cycle and continuously reduce ambient humidity.
