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

adaptable cooling solution designed for a wide array of cold storage applications. Whether

used in standalone cold rooms or integrated cold storage facilities, this series features three

models—DL, DD, and DJ—each optimized 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 delivers consistent and reliable cooling

performance, effectively extending the freshness and shelf life of stored food products.

**Key Features:**

1. **Robust and Corrosion-Resistant Build:**
The housing is constructed using advanced spray technology or crimped aluminum

with a surface spray finish, ensuring superior corrosion resistance and a sleek, modern

appearance.

2. **Efficient Coil Design for Optimal Performance:**
The coils are strategically arranged to reduce wind resistance. Precision-assembled copper

tubes, combined with aluminum fins and hydraulically expanded, minimize contact resistance

and enhance heat transfer efficiency.

3. **Stringent Quality Assurance:**
Each unit undergoes rigorous pressure testing and is cleaned with trichlorethylene to eliminate

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

expansion valve clogging during refrigerant charging.

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

and quiet operation. Its long-range airflow capability ensures dependable performance even in

low-temperature and high-humidity conditions.

5. **Effective Defrosting Mechanism:**
The unit features an insulated U-shaped tubular heating pipe integrated into the coil. With optimized

pitch and power distribution, it enables rapid and efficient defrosting, reducing downtime and

maintaining operational efficiency.

6. **Easy Installation:**
Slotted hangers are included for effortless lifting and installation, simplifying the setup process

and reducing installation time.

7. **Nitrogen Preservation for Quality Protection:**
Before shipping, each unit is treated with nitrogen packing to preserve its quality and performance

during storage and transit.

8. **Why Choose the D-Series Air Cooler?**
Combining advanced engineering, durable construction, and user-friendly features, the D-Series

air cooler is a dependable and efficient solution for maintaining optimal conditions in cold storage

environments. It ensures the preservation and quality of stored goods, making it an ideal choice

for a wide range of cold storage needs.
