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

cooling solution crafted to address a broad spectrum of cold storage requirements. It is perfectly

suited for both independent cold rooms and integrated cold storage setups, offering three

specialized models—DL, DD, and DJ—each meticulously designed to operate efficiently

within specific temperature ranges. Its compact and lightweight design optimizes space

utilization while maintaining ample storage capacity. The D-Series air cooler guarantees

consistent and dependable cooling performance, significantly prolonging the freshness

and shelf life of stored food items.

**Key Features:**

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

surface spray finish, ensuring superior corrosion resistance and a sleek, contemporary look.

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

combined with aluminum fins and hydraulically expanded, reduce contact resistance and

enhance heat transfer efficiency.

**Stringent Quality Assurance:**
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.

**High-Efficiency Fan Motors:**
Fitted 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 conditions.

**Effective Defrosting Mechanism:**
The unit includes an insulated U-shaped tubular heating element integrated into the coil.

With optimized spacing and power distribution, it facilitates rapid and efficient defrosting,

minimizing downtime and maintaining operational efficiency.

**Streamlined Installation:**
Slotted hangers are included for easy lifting and installation, simplifying the setup process

and reducing installation time.

**Nitrogen Protection for Quality Preservation:**
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, durable 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 wide range of cold storage needs.
