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

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

both standalone cold rooms and integrated cold storage facilities, this series offers three

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

ranges. Its compact and lightweight design optimizes space utilization without sacrificing

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

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

Key Features:

Durable and Corrosion-Resistant Construction:
The housing is crafted using advanced spray technology or crimped aluminum with a surface spray

finish, offering exceptional corrosion resistance and a sleek, modern aesthetic.

Optimized Coil Design for Enhanced Efficiency:
The coils are strategically designed to minimize wind resistance. Precision-assembled copper tubes,

paired with aluminum fins and hydraulically expanded, reduce contact resistance and maximize heat

transfer efficiency.

Rigorous Quality Control:
Each unit undergoes strict 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.

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.

Efficient Defrosting System:
The unit features an insulated U-shaped tubular heating pipe integrated into the coil. With optimized

pitch and power distribution, it enables quick and effective defrosting, minimizing downtime and

maintaining operational efficiency.

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

reducing installation time.

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 excellent choice for a variety of

cold storage needs.
