Product Introduction

The HD6-500 Series Drainage-Type Electrical Cabinet Dehumidifier is engineered to provide continuous and efficient moisture control for industrial enclosures. It operates based on the principle that warm, humid air condenses when it encounters a colder surface.

Using advanced electronic cooling technology, the device creates a cold zone inside the unit that remains lower than the ambient temperature. A built-in fan forces the hot, humid air from inside the electrical cabinet to pass across the cold end, where moisture rapidly condenses into water droplets. The HD6-500 continuously collects this condensation and discharges it outside the cabinet through a drainage outlet—effectively lowering internal humidity and preventing condensation-related failures.

This makes it ideal for electrical control cabinets, power distribution cabinets, PLC automation cabinets, outdoor communication enclosures, and other humidity-sensitive equipment.

• Designed for long-term, maintenance-free industrial use

Installation Method

4.1 Installation Dimensions

The HD6-500 supports both backplate mounting and DIN35 rail installation.
Standard backplate size: 121mm width × 34mm length × 1.2mm thickness.

4.2 Installation Instructions

The device can be installed using:

Backplate Installation (default)

Pre-drilled mounting holes on the rear allow quick installation on standard electrical cabinets.

DIN35 Rail Installation (optional)

Side and back rail clip holes support direct rail mounting for easy cabinet integration.

Installation Precautions

To ensure optimal operation and service life:

• Do not block the air inlet or outlet

• Ensure the drain port is properly connected to a water discharge pipe

• Leave sufficient space for ventilation and heat dissipation

• An external temperature and humidity sensor is required for full functionality
