Product Specification

   The rotary dehumidifier also known as a desiccant wheel dehumidifier, The drying wheel is the key component of the dehumidifier to absorb moisture. It is composed of a corrugated medium made of a special composite heat-resistant material. The corrugated medium contains moisture absorbent. This design has a compact structure and can provide a huge surface area for full contact between the humid air and the hygroscopic medium. Thereby greatly improving the dehumidification efficiency of the dehumidifier.

Structure of the Rotary Dehumidifier:

• Desiccant Wheel (Rotor): The core component is a large, porous wheel made from a desiccant material (like silica gel or zeolite) that absorbs moisture from the air. The wheel is divided into two sections: the process air section and the reactivation air section.

• Air Inlet and Outlet: The device has separate air channels for the process air (the air that needs to be dehumidified) and the reactivation air (air used to regenerate the desiccant).

• Blowers/Fans: These move the air through the system, one for the process air and one for the reactivation air.

• Heater:  a heater is used to warm the reactivation air to regenerate the desiccant material by releasing the absorbed moisture.

Applications:

1. Industrial, Scientific Research, Military and Municipal Engineering

• Including small storage rooms, substations, museums, archives, control rooms, pump houses, laboratories, etc.
• Key Requirements:
  • Museums/Archives: Maintain humidity to prevent mildew damage to cultural relics and documents.
  • Substations/Control Rooms: Reduce corrosion risks to electrical equipment from moisture, avoiding short circuits.
  • Laboratories: Ensure constant humidity for experimental accuracy (e.g., chemical analysis, biological culture).

2. Scenarios with Strict Humidity Control (RH < 45% at 22℃-24℃)

• Covering production workshops, warehouses, and special technical rooms.
• Typical Industries:
  • Electronics Manufacturing: Prevent moisture damage to precision components (e.g., semiconductor chips, PCB production).
  • Pharmaceutical Warehousing: Comply with GMP standards to avoid drug deliquescence.
  • Lithium Battery Production: Control humidity to prevent electrolyte deterioration and ensure battery safety.

3. Scenarios with High Moisture Generation (Regardless of RH Requirement)

• E.g., food processing plants, car washing workshops, or areas with frequent water operations.
• Challenge: Moisture from processes (e.g., steam, cleaning) requires continuous dehumidification to prevent equipment corrosion.

4. Low-temperature and High-humidity Environments

• E.g., cold storage rooms (2℃-8℃) or outdoor facilities in rainy regions.
• Risk: Condensation on surfaces may damage materials (e.g., metal rust, insulation degradation).

5. Low-temperature Environments Prohibiting Condensation

• E.g., air-conditioned cold halls, refrigerated transport vehicles, or precision instrument rooms.
• Control Objective: Maintain dew-point temperature below ambient temperature to avoid water droplets on equipment surfaces.
