DH1-20 (DH-021) Intelligent Enclosure Dehumidifier

DH1-20 (DH-021) Intelligent Enclosure Dehumidifier

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.

Notes:
1. The rated power is related to the cabinet’s inner volume and airtightness, and the general reference value is:
0.5cubic meter cabinet choose 15w
1.0cubic meter cabinet choose 30w
1.5cubic meter cabinet choose 40w
2.0cubic meter cabinet choose 60w
Cabinet volume is calculated according to the physical dimension (Length*Width*Height).2. The DH-021 intelligent enclosure dehumidifier is with a built-in external sensor. The sensor accuracy is 5%.3. The intelligent enclosure dehumidifier provides passive NO contact for external heater connection, capacity is AC250V5A. You can free to order heaters or purchase with the DN series.
