Why Choose the DJ-1681E
168 L/Day Nominal Moisture Removal Capacity
The DJ-1681E provides a nominal dehumidification capacity of 168 liters per day under test conditions of 30°C and 80% RH. It is designed for industrial and commercial spaces with substantial moisture-control requirements.
Real-Time Temperature and Humidity Display
The LCD display shows ambient temperature and relative humidity, helping operators monitor environmental conditions and adjust humidity settings as required.
Automatic Defrosting and Restart Protection
Automatic defrosting helps maintain operation when frost forms on the evaporator under suitable conditions. A three-minute restart delay helps protect the compressor against frequent restarts.
Automatic Humidity Control
The adjustable humidity control supports humidity management according to the needs of the application. The final achievable humidity depends on environmental conditions and the operating characteristics of the equipment.

How Does the DJ-1681E Work?
Working Principle
The dehumidified air then passes through the condenser coil, where it is reheated before being returned to the indoor environment. This process reduces indoor humidity while helping maintain suitable air circulation.
When the preset humidity level is reached, the humidity control system stops the dehumidification operation. The unit resumes operation when the measured humidity rises above the set level, according to the controller's operating logic.
168 L/day Industrial Dehumidifier Applications
Factories and Production Workshops
Manage excess humidity in production areas where moisture can affect materials, packaging, equipment or manufacturing processes.
Warehouses and Storage Facilities
Help control moisture in storage environments containing moisture-sensitive products, raw materials, packaging or inventory.
Greenhouses
Support humidity management in greenhouse environments. Select the equipment based on temperature, ventilation, crop requirements and the actual moisture load.
Indoor Swimming Pool Facilities
Help reduce excess airborne moisture in suitable indoor pool environments. Equipment sizing should account for pool water surface area, water temperature, room conditions and ventilation.
Installation Considerations
Installation
Install the dehumidifier in a well-ventilated area to ensure proper air circulation. Avoid placing the unit in enclosed spaces or corners where airflow may be restricted or recirculated, as this can reduce dehumidification efficiency.
Place the dehumidifier on a firm, level surface to minimize vibration and operating noise. Keep the unit away from direct sunlight and heating appliances or other heat sources. Ensure that the air inlet and outlet remain unobstructed for optimal performance.
