Drawers-type anhydrous constant humidity collection cabinet

【Cabinet Structure】

1. Made of high-quality structural steel plates, with high-load-bearing steel shelves. The bottom is equipped with high-quality universal casters, featuring excellent airtightness (using silicone sealing strips); the cabinet door's viewing window is made of 5mm tempered glass;

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

3. Surface treatment: Adopts advanced powder spraying process with multiple procedures, ensuring strong corrosion resistance;

4. Humidity control system: Intelligently controls the moisture absorption and exhaust cycles through microcomputer programming, providing stable and accurate dehumidification with an eco-friendly design;

5. Main unit material: The housing of the moisture-absorbing main unit is made of PPS fire-resistant material, with heat resistance up to 230℃.
6. Uses magnetic sealing strips for refrigerators; the door handle is a flat, pressurized, high-integrity integrated handle lock with anti-theft function. Both inner and outer surfaces are treated with electrostatic spraying to ensure the surface coating will not peel or age.

【Product Features】

1. Fully automatic electronic dehumidification and humidification, requiring no manual operation, meeting long-term quality-preserving storage needs;

2. Energy-saving core, with the fastest dehumidification speed, dust-free, no dripping, no noise, no consumables, truly low power consumption design;

3. Can reach low humidity state without additional operations, with low use cost, making it the most economical design at present; 

4. Built-in dehumidification core, avoiding external exposure faults and accidental touch hazards, while improving safety and preventing artificial damage;

5. Digital humidity control design, with LED digital display of temperature/humidity on the window, and freely adjustable humidity. The sensor is imported from a foreign brand, with an error of ±2%RH;

6. Both inner and outer surfaces of the constant humidity cabinet are powder-sprayed with high-quality brand paint;

7. The cabinet of the constant humidity cabinet is made of high-strength cold-rolled steel plates, with precision high-frequency argon arc welding; the cabinet door uses non-toxic magnetic rubber strips;

8. The glass door is made of high-quality tempered glass, with good waterproof, dustproof and airtight performance;

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

10. Excellent fast and stable dehumidification capacity and good sealing performance, which can keep the internal humidity of the cabinet unaffected by the environment.
11. Requirements for dehumidification and humidification core: Adopt high-efficiency dehumidification core, with the core housing made of PPS + Class A flame-retardant material, and moisture resistance up to over 300℃, to avoid the risk of core melting caused by instantaneous overcurrent. The solid polymer electrolyte membrane for moisture absorption must be imported (no need for replacement within 8 years), which can directly electrolyze and continuously remove moisture from the air, discharge it to the outside in gaseous state, and be repeatedly regenerated and recycled. The core shall have the advantages of fast dehumidification, ultra-quiet operation, low power consumption and no consumables. The main accessories of the dehumidification core shall come from internationally renowned enterprises.
12. Requirements for fault prompt: High-brightness LCD display of temperature and humidity, 24-hour all-weather monitoring of the dehumidification core's operation. Set the required humidity through the keys on the LCD screen, which is simple, clear and easy to operate. The temperature display range is 1-99℃, and the humidity display range is 1-99%RH. The LCD panel has a fault prompt function. Through program setting, the working status of the dehumidification core can be clearly understood. If the product fails, the fault location can be immediately identified for quick product repair.  

13. Requirements for power failure protection: After power outage, the system uses the "chemical moisture absorption supplement" function to absorb moisture, ensuring the humidity rise inside the cabinet is less than 10%RH within 24 hours after power outage. Meanwhile, the system has a memory function, so the humidity does not need to be reset when power is restored.

【Dehumidification Principle】

The drawer-type high-efficiency intelligent anhydrous constant humidity cabinet for cultural relics, when the mobile anhydrous constant humidity cabinet is powered on and started, the dehumidification core performs regeneration work: the inner door is closed and the outer door is opened, so that the drying material is regenerated and exhausts moisture, making water vapor evaporate out of the cabinet. After regeneration, the outer door is closed and the inner door is opened, so that the drying material dehumidifies inward, adsorbing water vapor inside the cabinet and reducing the internal humidity. The regeneration and dehumidification steps circulate under the control of the control panel, effectively adjusting the internal humidity of the cabinet.
