The D-Series air cooler, commonly known as a cold air cooler, is a highly versatile and

adaptable cooling solution designed to meet a wide range of cold storage demands. It is

ideal for both standalone cold rooms and integrated cold storage systems, offering three

specialized models—DL, DD, and DJ—each carefully engineered to operate efficiently

within specific temperature ranges. Its compact and lightweight design maximizes space

efficiency while maintaining ample storage capacity. The D-Series air cooler ensures

consistent and reliable cooling performance, significantly extending the freshness and

shelf life of stored food products.

**Key Features:**

**Robust and Corrosion-Resistant Construction:**
The housing is crafted using advanced spray technology or crimped aluminum with a

surface spray finish, providing exceptional corrosion resistance and a sleek, modern

appearance.

**Optimized Coil Design for Enhanced Efficiency:**
The coils are strategically designed to minimize wind resistance. Precision-assembled

copper tubes, paired with aluminum fins and hydraulically expanded, reduce contact

resistance and maximize heat transfer efficiency.

**Rigorous Quality Control:**
Each unit undergoes strict pressure testing and is cleaned with trichlorethylene to remove

oil, water, and oxide residues. This ensures a blockage-free system, preventing issues

such as expansion valve clogging during refrigerant charging.

**High-Performance Fan Motors:**
Equipped with specialized fan motors, the air cooler delivers low energy consumption, high

airflow, and quiet operation. Its long-range airflow capability ensures reliable performance

even in low-temperature and high-humidity environments.

**Efficient Defrosting System:**
The unit features an insulated U-shaped tubular heating pipe integrated into the coil. With

optimized pitch and power distribution, it enables quick and effective defrosting, minimizing

downtime and maintaining operational efficiency.

**Simplified Installation Process:**
Slotted hangers are included for easy lifting and installation, streamlining the setup process

and reducing installation time.

**Nitrogen Preservation for Quality Assurance:**
Before shipping, each unit is treated with nitrogen packing to maintain its quality and

performance during storage and transit.

**Why Choose the D-Series Air Cooler?**
With its advanced engineering, robust construction, and user-friendly features, the

D-Series air cooler is a reliable and efficient solution for maintaining optimal conditions

in cold storage environments. It ensures the preservation and quality of stored goods,

making it an excellent choice for a variety of cold storage needs.
