The D-Series air cooler, also known as a cold air cooler, is a highly flexible 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 specialized

models—DL, DD, and DJ—each carefully engineered 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:**

**Durable and Corrosion-Resistant Construction:**
The unit’s housing is made using advanced spray technology or crimped aluminum with a

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

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

with aluminum fins and hydraulically expanded, reduce contact resistance and improve 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 offers 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 element integrated into the coil. With

optimized spacing 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, simplifying 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.
