The DH-021 Intelligent Enclosure Dehumidifier (semiconductor dehumidifier) is a device used to control and maintain the environmental humidity inside the electrical cabinet. Its main function is to reduce the humidity level inside the electrical cabinet to ensure the normal operation and protection of electrical equipment.

This Enclosure Dehumidifier is equipped with an intelligent control module, which uses a microcomputer processing chip with strong anti-interference. The double-row digital tubes display the measured value and the set value at the same time, and alternately display the current temperature and humidity, and realize the automatic control function of the humidity. Contact directly to get the dehumidifier for Enclosures or outdoor enclosures.
