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

adaptable cooling solution tailored for a diverse array of cold storage applications. It is

well-suited for both standalone cold rooms and integrated cold storage systems, offering

three specialized models—DL, DD, and DJ—each meticulously designed 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 dependable cooling performance, significantly enhancing the freshness and shelf life of

stored food products.

**Key Features:**

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

surface spray finish, ensuring exceptional resistance to corrosion and a sleek, modern appearance.

**Efficient Coil Design for Optimal Performance:**
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:**
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 conditions.

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

With optimized spacing and power distribution, it enables 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.
