【Cabinet Structure】

1. Made of high-quality structural steel plates with high-load-bearing steel shelves. The base is equipped with high-quality universal casters, excellent sealing (silicone sealing strips), and the door viewing window uses 5mm tempered glass;

2. Standard configuration: Includes pressurization, high shock-absorbing rubber strips, and key lock installation;

3. Surface treatment: Advanced multi-step powder coating process for strong corrosion resistance;

4. Humidity control system: Microcomputer-programmed intelligent control of moisture absorption and exhaust cycles, stable and precise dehumidification, eco-friendly design;

5. Main unit material: The moisture-absorbing main unit casing uses PPS flame-retardant material, heat-resistant up to 230°C.
6. Sealed with magnetic refrigerator-style sealing strips; door handle uses a flat-press high-strength integrated handle lock with anti-theft function; both inner and outer surfaces are electrostatically sprayed to ensure the coating does not peel or age.

【Product Features】

1. Fully automatic electronic dehumidification and humidification, no manual operation required, suitable for long-term preservation storage;

2. Most energy-efficient core, fastest dehumidification, dust-free, no dripping, no noise, no consumables, truly low-power design;

3. Achieves low humidity without additional operations, low usage cost, currently the most economical design; 

4. Built-in dehumidification core, avoids external exposure faults and accidental contact risks, improves safety, and prevents human damage;

5. Digital humidity control design, digital LED display of temperature/humidity, freely adjustable humidity, sensors are imported original foreign brands, error ±2%RH;

6. Inner and outer surfaces of the humidity cabinet are treated with high-quality brand powder coating;

7. Cabinet body made of high-strength cold-rolled steel plates, precision high-frequency argon arc welding, door sealed with non-toxic magnetic rubber strips;

8. Glass door uses high-quality tempered glass, waterproof, dustproof, and with good airtightness;

9. After power failure, the system ensures humidity rise inside the cabinet is less than 10% (within 24 hours);

10. High-quality, fast, and stable dehumidification capability, excellent sealing performance, keeps internal humidity unaffected by the environment.
11. Dehumidification and humidification core requirements: High-efficiency dehumidification core, core casing made of PPS + Class A flame-retardant material, moisture resistance up to 300°C or higher, avoiding risks of core melting due to sudden high current. Solid polymer electrolyte membrane for moisture absorption must be imported (no replacement needed for 8 years), directly electrolyzes and continuously removes moisture from the air, discharging it externally in gaseous form, reusable and recyclable. The core must have fast dehumidification, ultra-quiet operation, low power consumption, no consumables, etc. Key components of the dehumidification core must come from internationally renowned companies.
12. Fault indication requirements: High-brightness LCD display of temperature and humidity, 24/7 monitoring of the dehumidification core’s operation. Set desired humidity via surface buttons on the LCD display, simple and easy to operate. Temperature display range: 1-99°C, humidity display range: 1-99%RH. The LCD panel has fault indication function; through programmed settings, the working status of the dehumidification core can be clearly understood. If a fault occurs, the faulty part can be quickly identified for prompt repair.   

13. Power-off protection requirements: After power failure, the system uses "chemical moisture absorption compensation" to absorb moisture, ensuring humidity rise inside the cabinet is less than 10%RH within 24 hours. After power resumes, humidity settings do not need resetting; the system has memory function.

【Dehumidification Principle】

When the drawer-type high-efficiency intelligent water-free constant humidity preservation cabinet or movable water-free constant humidity preservation cabinet is powered on, the dehumidification core regenerates, the inner door closes, and the outer door opens to allow drying material regeneration and moisture discharge, evaporating water vapor outside the cabinet. After regeneration, the outer door closes, and the inner door opens for internal dehumidification, adsorbing moisture inside the cabinet to reduce humidity. The regeneration and dehumidification steps cycle under the control panel’s management, effectively regulating internal humidity.
