Optical Instrument Smart Dehumidifying Cabinet – Product Introduction
I. Product Overview
The Optical Instrument Smart Dehumidifying Cabinet is a professional-grade storage device specifically designed for scientific research institutes, industrial enterprises, government agencies, and precision manufacturing environments. Integrating intelligent dehumidification, maintenance‑free operation, non‑magnetic properties, and high strength, the cabinet utilizes advanced LLDPE material and a double‑layer rotational molding process. It provides a safe storage space with stable temperature, stable humidity, and magnetic‑interference‑free conditions for precision optical equipment, optoelectronic devices, and various sensitive components.
II. Core Material & Manufacturing Process
Premium LLDPE Material: The cabinet body is made of high‑grade Linear Low‑Density Polyethylene (LLDPE) resin. This material offers excellent corrosion resistance, electrical insulation (especially high‑frequency insulation), and weather resistance, effectively eliminating external magnetic interference.
- Double‑Layer Rotational Molding: Manufactured using a single‑process double‑layer rotational molding technique.
- Physical properties: High strength, good toughness, impact resistance, drop resistance, and durability.
- Chemical properties: 100% waterproof, mildew‑proof, UV‑resistant, and salt‑spray resistant – suitable for extreme harsh environments.
- Fully Non‑Magnetic Design: The entire product contains no magnetically conductive materials (including structural parts such as metal shafts, which are either non‑magnetized or made from specially selected non‑magnetic materials), effectively preventing magnetic interference with stored optoelectronic and electromagnetic equipment.
III. Smart Dehumidification Performance & Technical Features
- Alloy Chemical Absorption Technology: Utilizes industry‑leading “shape memory alloy” chemical absorption drying technology. The system intelligently adjusts its operating frequency based on a built‑in humidity control model, quickly reducing internal humidity to below 60% RH and maintaining it within a set range.
- Power‑Off Protection: Features a powerful “memory” dehumidification capability. In the event of a power outage, the dehumidifier cartridge continues to provide dehumidification for approximately 12 hours using the memory alloy characteristic. When power is restored, the system automatically returns to its previous state without manual intervention.
- Wide Temperature Range Adaptation: The cabinet operates normally in extreme temperatures from -40°C to +50°C. Combined with the reinforced enclosure design, it ensures extreme stability of the internal environment.
- Flexible Layout: The interior is divided into three main storage zones (upper, left, and right). Additionally, the lower section has three adjustable shelves, providing high space utilization and convenient classification of items of different sizes.

VI. Operating Instructions & Precautions
1. Quick Start
Placement: The cabinet must be placed on a level, sturdy surface. Leave at least 20 cm of space behind the cabinet for moisture exhaust.
No‑Load Operation: When using the cabinet for the first time or after a long shutdown, operate it empty for at least 12 hours. Wait until the humidity drops to the target value before loading items.
2. Humidity Setting & Calibration
Display Panel:
Green LED – displays current temperature (non‑adjustable).
Red LED – displays current humidity (adjustable).
Setting Humidity: Briefly press the UP or DOWN key, adjust to the desired number, then release.
Calibration Mode: Press and hold the UP or DOWN key for 3 seconds to manually calibrate the displayed humidity value.
Reset to Factory Defaults: Press and hold both UP and DOWN keys simultaneously; the humidity display will reset to factory settings.
3. Operational Precautions
Environmental Restrictions: Do not place the cabinet near air conditioner vents, exhaust fans, in damp or high‑humidity areas, or in direct sunlight.
Storage Guidelines: Do not place items directly against the dehumidifier cartridge. Do not block the moisture exhaust holes. Chemicals or food items must be stored in sealed containers to prevent interference with dehumidification performance.
Door Management: When accessing items, keep the door open for as short a time as possible to maintain stable internal humidity.
