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

efficient cooling system engineered for a wide range of cold storage needs. It is suitable for

both standalone cold rooms and integrated cold storage facilities. The series comprises

three models—DL, DD, and DJ—each designed to operate optimally within specific

temperature ranges. Its compact and lightweight structure maximizes space utilization

without sacrificing storage capacity. The air cooler ensures consistent and reliable cooling

performance, significantly enhancing the freshness and extending the shelf life of stored

food products.

Key Features:

1. **Durable Build:**

The housing is crafted using advanced spray technology or crimped aluminum with a surface

spray finish, offering superior corrosion resistance and a sleek, modern aesthetic.

2. **Optimized Coil Design:**
The coils are strategically arranged to minimize wind resistance. After precise assembly,

they undergo hydraulic expansion and are fitted with aluminum fins on copper tubes, reducing

contact resistance and enhancing heat transfer efficiency.

3. **Rigorous Quality Control:**
Each unit is subjected to thorough pressure testing and cleaned with trichlorethylene to remove

oil, water, and oxide residues from the tubes. This ensures the system remains free from

blockages, preventing issues like expansion valve clogging during refrigerant charging.

4. **High-Efficiency 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.

5. **Effective Defrosting System:**
The unit incorporates an insulated U-shaped tubular heating pipe within the coil. With an

optimized pitch and power distribution, it enables rapid and efficient defrosting, minimizing

downtime and maintaining operational efficiency.

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

and reducing installation time.

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

during storage and transit.With its cutting-edge design and advanced 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 ideal

choice for a variety of cold storage applications.
