drawer-type anhydrous constant humidity collection cabinet

【Cabinet Structure】

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

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

3. Surface treatment: Advanced multi-process powder coating is adopted, which has strong corrosion resistance;

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

5. Main unit material: The shell of the moisture-absorbing main unit is made of PPS fire-resistant material, with a heat resistance of up to 230℃.
6. Adopts a magnetic sealing strip sealing method for refrigerators. The door handle is a flat-press high-integrity integrated handle lock with anti-theft function. Both inner and outer surfaces are electrostatically sprayed to ensure that the surface coating will not peel off or age.

【Product Features】

1. Fully automatic electronic dehumidification and humidification, no manual operation required, meeting the requirements of long-term quality-preserving storage;

2. The most energy-efficient movement, with the fastest dehumidification, dust-free, no dripping, no noise, no consumables, and a truly low-power design;

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

4. Built-in dehumidification movement, avoiding exposure failures and accidental touch risks, while improving safety and preventing man-made damage;

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

6. The inner and outer surfaces of the constant humidity cabinet are powder-coated 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 a power outage, the system can ensure that the humidity rise in the cabinet is less than 10% (within 24 hours);

10. High-quality, fast and stable dehumidification capacity, and good sealing performance, which can keep the humidity inside the cabinet unaffected by the environment.
11. Requirements for dehumidification and humidification movement: Adopt a high-efficiency dehumidification movement, the movement shell is made of PPS + Class A flame-retardant material, with a humidity resistance of up to over 300℃, to avoid the risk of the movement melting due to excessive instantaneous current. The solid polymer electrolyte membrane for moisture absorption must be an imported product (no need to replace within 8 years), which can directly electrolyze and continuously remove moisture from the air, and discharge it to the outside in a gaseous state, and can be repeatedly regenerated and recycled. The movement needs to have the advantages of fast dehumidification, ultra-quiet operation, low power consumption, no consumables, etc. The main accessories of the dehumidification movement must come from internationally renowned enterprises.
12. Fault prompt requirements: High-brightness liquid crystal display for temperature and humidity, 24-hour all-weather monitoring of the dehumidification movement. Set the required humidity through the keys on the liquid crystal display, 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 liquid crystal panel has a fault prompt function. Through program settings, you can clearly understand the working status of the dehumidification movement. If the product fails, you can immediately judge the fault location and quickly repair the product.  

13. Power outage protection requirements: After a power outage, the system uses the "chemical moisture absorption supplement" function to absorb moisture, ensuring that the humidity rise in the cabinet is less than 10%RH within 24 hours after the power outage. At the same time, the humidity does not need to be reset after power is restored, and the system has a memory function.

【Dehumidification Principle】

The drawer-type high-efficiency intelligent anhydrous constant humidity storage cabinet for cultural relics, when the movable anhydrous constant humidity storage cabinet is powered on and started, the dehumidification movement regenerates and operates, the inner door is closed, and the outer door is opened, so that the drying material is regenerated and dehumidified, and the water vapor evaporates out of the cabinet. After regeneration is completed, the outer door is closed, the inner door is opened, and the drying material dehumidifies inward, adsorbing the water vapor in the cabinet and reducing the humidity inside the cabinet. The regeneration and dehumidification steps are cyclically performed under the control of the control panel, effectively adjusting the humidity inside the cabinet.
