Digital Display Dehumidifying Box 25L 110V Product Overview

The 25L electronic constant humidity dry cabinet is designed for moisture-proof storage of 3D printing filaments, camera lenses and precision electronic components. It adopts a high-performance dehumidification module and features low noise and low power consumption. It is an ideal choice for 3D printing studios, photographic studios, photography enthusiasts and similar users.

Note: The printing filaments shown in the pictures are for reference only and are not included in the packing list.

Product Parameters Voltage AC 110V Rated power 8W Capacity 25L (6.6 US gal) Material Cold-rolled steel plates + tempered glass door Humidity control range 25%–60% RH Function Dehumidification Recommended storage humidity PLA: 30%–50% RH
ABS: 20%–40% RH
PETG: 20%–40% RH
TPU: 20%–40% RH
PC: 20%–30% RH Precautions 1. The dry box only dehumidifies and cannot humidify. Therefore, when the ambient humidity is lower than the target humidity, the humidity displayed by the dry box will be basically consistent with the ambient humidity. 2. The dry box cannot control temperature. It only monitors the actual temperature inside the cabinet, which fluctuates with the ambient temperature. 3. To achieve optimal dehumidification performance, ensure the glass door is tightly sealed against the cabinet body during operation. 4. Items must be fully dried before being placed inside the cabinet. Do not put damp items directly into the cabinet. 5. Humidity inside the cabinet will rise when the door is opened to put in or take out items. This is normal. It is caused by external air entering the cabinet or the humidity of the newly placed items being higher than the internal humidity. (The increase in internal humidity depends on the door opening duration, external air humidity and moisture contained in the items.) 6. The dehumidification speed is related to the ambient humidity and the dampness of stored items. Higher ambient humidity, more items or wetter items will require longer dehumidification time, and vice versa. If the target humidity range cannot be achieved after prolonged dehumidification, perform an empty cabinet test to verify the dehumidification function of the dry box. Product Features

1. Heat-free effective dehumidification
   Designed for moisture-proof storage to preserve original filament performance.
2. Adjustable & accurate humidity control
   Adjustable humidity range: 25–60% RH, matching storage requirements for different filaments and optical devices. The external digital display shows real-time temperature and humidity. Data can be read without opening the cabinet door, preventing humidity disturbance inside the chamber.
3. Silence & low power consumption
   The dry box runs at low noise and low power consumption, ensuring energy-saving and stable long-term operation.
4. Large capacity with flexible layout
   The cold-rolled steel cabinet with a transparent tempered glass door allows direct visual check of the filament state. It is also compatible with camera lenses and precision electronic parts.
5. Secure locking & reliable sealing
   The mechanical key lock prevents unintended opening and dust ingress, and protects valuable filaments and photography devices. The well-sealed cabinet body reduces external moisture intrusion.
6. Multi-purpose usage
   One cabinet for multiple purposes: moisture-proof storage of 3D printing filaments, photography equipment, electronic components and collectibles.

Digital Display The digital temperature and humidity display screen supports easy reading of temperature and humidity values. It is compact in size and sensitive in response, providing real-time environmental monitoring. Door The transparent visible door allows clear observation of stored filaments without opening the cabinet. It is equipped with a key lock mechanism to secure the door for dust-proof and moisture-proof purposes. Dehumidifier The dehumidifier features multi-gear knob adjustment to set the target humidity for different filaments with simple and intuitive operation. The modular integrated structure facilitates disassembly and maintenance. Rear Panel The rear ventilation and heat dissipation panel with the multi-groove structure accelerates heat dissipation of the dehumidifier module and prevents local heat accumulation inside the cabinet. It is easy to assemble and disassemble. Operation Method

A. Machine Placement

1. Place the unit on a horizontal and solid surface. Maintain a clearance of no less than 5cm between the unit and surrounding objects or walls.
2. Do not place the unit in locations with drastic temperature fluctuations, direct sunlight, heavy dust, strong airflow, or dark and humid conditions. These environments will reduce or destabilize dehumidification performance.

B. Power On

1. Connect the power supply. The green operating indicator light on the core module will turn on, and the unit starts working.
2. Insert the adapter plug into the AC power socket.
3. Then insert the DC plug of the adapter into the DC socket of the unit.

Caution: Do not use an incorrect power supply. The unit is only compatible with a power adapter with an output of DC 5V and a current of 2A or higher.

C. Humidity Setting & Adjustment

1. Select and adjust the humidity according to the stored items.
2. Turn the knob to the corresponding position, close the door, and run the unit empty for 8–12 hours. After the humidity stabilizes, check whether the reading on the hygrometer falls within the required humidity range.
3. If the humidity is within the required range, open the door, place items into the dry box, and close the door.
4. If the humidity is outside the required range, adjust the knob position:
   • If the displayed humidity is higher than the required range, turn the knob slightly clockwise.
   • If the displayed humidity is lower than the required range, turn the knob slightly counterclockwise.
5. After fine adjustment, close the door and wait for the internal humidity to stabilize, then check the displayed humidity. If it is within the required range, proceed to Step 3. If it is still outside the range, repeat Step 4 until the target humidity is achieved.
