The D-series air cooler, also known as a cold air cooler, is a highly adaptable and energy-efficient

cooling system designed to meet diverse cold storage requirements. It is ideal for both

independent cold rooms and integrated cold storage setups. The series includes three

models—DL, DD, and DJ—each engineered to perform effectively within specific temperature

ranges. Its compact and lightweight design optimizes space usage without compromising storage

volume. The air cooler delivers stable and dependable cooling, significantly improving the freshness

and prolonging the shelf life of stored food items.

Key Features:

1. **Robust Construction:**
The housing is manufactured using advanced spray technology or crimped aluminum with a

surface spray finish, providing excellent corrosion resistance and a modern, polished appearance.

2. **Efficient Coil Configuration:**
The coils are strategically designed to reduce wind resistance. After precise assembly, they are

hydraulically expanded and fitted with aluminum fins on copper tubes, minimizing contact resistance

and maximizing heat exchange efficiency.

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

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

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 consistent performance even in low-temperature

and high-humidity conditions.

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

pitch and power distribution, it provides quick and efficient defrosting, reducing downtime and maintaining

operational efficiency.

6. **Simplified Installation Process:**
Slotted hangers are included for easy lifting and installation, making the setup process straightforward

and time-efficient.

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

storage and transportation.

With its innovative design and advanced 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 excellent choice for a variety of cold storage applications.
