The D-Series air cooler, also referred to as a cold air cooler, is a highly flexible and adaptable

cooling solution designed for a variety of cold storage applications. Ideal for both standalone

cold rooms and integrated cold storage facilities, this series includes three models—DL, DD,

and DJ—each tailored to operate efficiently within specific temperature ranges. Its compact

and lightweight design maximizes space efficiency without compromising storage capacity.

The D-Series air cooler delivers consistent and reliable cooling performance, significantly

extending the freshness and shelf life of stored food products.

Key Features:

1.Durable and Corrosion-Resistant Build:
The housing is constructed using advanced spray technology or crimped aluminum with a

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

2.Optimized Coil Design for Superior Efficiency:
The coils are strategically arranged to reduce wind resistance. Precision-assembled and

hydraulically expanded, the copper tubes are paired with aluminum fins, minimizing contact

resistance and enhancing heat transfer efficiency.

3.Stringent Quality Control:
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 System:
The unit features an insulated U-shaped tubular heating pipe integrated into the coil. With an

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

downtime and maintaining operational efficiency.

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

and cutting down on installation time.

7.Nitrogen Preservation for Quality Assurance:
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?
With its advanced engineering, robust 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.
