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

cooling solution designed for a wide variety of cold storage applications. It is ideal for both

standalone cold rooms and integrated cold storage systems, offering three distinct 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

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, providing exceptional corrosion resistance and a sleek, modern appearance.

**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.
