The D-series air cooler, also referred to as a cold air cooler, is a versatile cooling device suitable

for various types of cold storage facilities, including standalone cold rooms and combined cold

storage systems. This series comprises three models—DL, DD, and DJ—each designed to

operate efficiently at different temperature ranges. Characterized by its compact and lightweight

design, the D-series air cooler maximizes space utilization without occupying excessive cold

storage area. It ensures uniform and efficient cooling, significantly enhancing the freshness and

preservation of stored food items.

1. **Durable Construction:** The unit's housing is crafted using advanced spray technology or

crimped aluminum with a surface spray finish, offering robust corrosion resistance and an

aesthetically pleasing appearance.

2. **Optimized Coil Design:** The coils are innovatively arranged to minimize wind resistance.

After precise measurement and assembly, the coils are hydraulically expanded and wrapped

with aluminum fins on copper tubes, reducing contact resistance and enhancing heat transfer

efficiency.

3. **Rigorous Quality Control:** Each product undergoes a comprehensive pressure test and

is cleaned with trichlorethylene to remove oil, water, and oxide residues from the tubes. This

ensures that the system remains free from blockages caused by debris, preventing issues

such as expansion valve malfunctions during refrigerant charging.

4. **Efficient Fan Motors:** Equipped with specialized fan motors, the air cooler boasts low

power consumption, high air volume, and minimal noise levels. Its long-range airflow capability

ensures reliable performance even in low-temperature and high-humidity environments.

5. **Effective Defrosting System:** The unit features an insulated U-shaped tubular heating

pipe integrated into the coil. With a well-designed pitch and power distribution, it achieves rapid

and effective defrosting, minimizing downtime.

6. **Easy Installation:** The inclusion of slotted hangers facilitates straightforward lifting and

installation of the unit.

7. **Nitrogen Preservation:** Prior to dispatch, each unit undergoes nitrogen packing to maintain

its integrity and performance during storage and transportation.This combination of advanced

features makes the D-series air cooler a reliable and efficient solution for maintaining optimal

conditions in cold storage environments.
