How Does the DJ-3881E Work?

The principle of the dehumidifier is-to discharge theair vapor-cooled self-condensing liquid through daocooling,reduce the air humidity,and achieve thedehumidification effect. The working principle is topass the compressor dao,two devices (evaporator,condenser)，capillary tube,and The refrigerant in thecopper pipe changes from a high-temperature andhigh-pressure gas to a low-temperature and low-pressure liquid.The air inhaled into the machine has alarge temperature difference, which quickly condenseswater droplets and slides into the drain box throughthe two fins to reduce the air humidity and achievethe effect of dehumidifcation.

360 L/Day Industrial Dehumidifier Applications

Warehouses & Storage

Humidity control can help protect moisture-sensitive materials and products stored in warehouses.

Factory & Production Workshops

Industrial processes may require controlled humidity to maintain suitable working conditions and protect materials or equipment. The DJ-3881E can be evaluated for production areas according to the actual moisture load and environmental requirements.

Greenhouses & Horticulture

Greenhouses can experience high humidity caused by irrigation, plant transpiration and temperature changes. A dehumidifier can be considered where excess moisture and condensation need to be controlled.

Swimming Pools & High-Humidity Areas

Indoor swimming pools and similar environments can generate significant moisture. Dehumidification can help control indoor humidity and reduce excessive condensation on building surfaces.The equipment should be selected according to pool area, water surface, indoor temperature, RH and moisture load.

Other Moisture-Sensitive Environments

The DJ-3881E can also be evaluated for other applications where continuous humidity control is required.
Contact TOJJE with your environmental and technical requirements for model selection.

How to Select an Industrial Dehumidifier

Before requesting a quotation, provide the following information:

Application: Warehouse / Factory / Workshop / Greenhouse / Swimming Pool / Other

Room Dimensions: Length × Width × Height

Current Conditions: Temperature: ___ °C Relative Humidity: ___ %RH

Target Conditions: Target RH: ___ %RH Target Temperature: ___ °C

Moisture Sources: Production process,Drying process,Washing,Irrigation,Open water,Personnel,External humid air.

Power Supply: Voltage / Phase / Frequency

Installation: Indoor / Outdoor / Floor-standing / Other

Drainage: Gravity drainage / Hose drainage / Other

This information allows the TOJJE technical team to evaluate whether the DJ-3881E is appropriate or whether another model would be more suitable.

Installation Considerations

The dehumidifier should be installed in a place with air circulation, and avoid placing it in dead corners, causing short circuits in the air flow and failing to achieve the required dehumidification effect. At the same time, the dehumidifier should be placed on a firm and flat floor to avoid vibration and noise. Also, avoid direct sunlight or close to heating appliances.

Frequently Asked Questions

The nominal dehumidification capacity is 360 L/day at 30°C and 80% RH.

Actual dehumidification performance depends on operating temperature, relative humidity and other site conditions.

The standard specification is 380V/50Hz.
Please confirm the required electrical configuration before ordering.

The circulating airflow is 4,000 m3/h.

The current product specification lists a humidity control range of 40–95% RH, while the feature section states 45–95% RH.

The final control range should be confirmed with TOJJE before quotation.
