The D-Series air cooler, also known as a cold air cooler, is a highly versatile and adaptable

cooling system designed for a wide range of cold storage applications. Suitable for both

standalone cold rooms and integrated cold storage facilities, this series includes three

models—DL, DD, and DJ—each engineered to operate efficiently within specific temperature

ranges. Its compact and lightweight design maximizes space utilization without compromising

storage capacity. The D-Series air cooler ensures consistent and reliable cooling performance,

significantly enhancing the freshness and shelf life of stored food products.

Key Features:

1.Durable and Corrosion-Resistant Construction:
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 for Enhanced Efficiency:
The coils are strategically arranged to minimize wind resistance. Precision-assembled and

hydraulically expanded, the copper tubes are fitted with aluminum fins, reducing contact

resistance and maximizing heat transfer efficiency.

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

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 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.Efficient 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 quick and effective defrosting, minimizing

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 Assurance:
Before shipping, each unit is treated with nitrogen packing to maintain its quality and performance

during storage and transit.

Why Choose the D-Series Air Cooler?
With its advanced engineering, robust construction, and user-friendly 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 needs.
