The D-series air cooler, also known as an air cooler, is a cooling device suitable for various cold storages such as civil cold storage or combined cold storage. This type of cooler has three different types: DL, DD, and DJ, each one is suitable for different cold storages with varying storage temperatures. One of its benefits is its compact structure and lightweight design which doesn't take up too much space in the storage area. It's equipped with uniform storage temperature, high efficiency and other advantages which can quickly cool down the food stored in the cold storage and greatly improve the freshness of the stored food.
The shell of the product is designed with a plastic spraying process or embossed aluminum plate, which is then treated with a plastic spraying finish. This results in a strong corrosion resistance, as well as a beautiful appearance.
In order to reduce the wind side resistance, the coil is arranged in a novel way. Upon installation, the copper tube is tightly attached to the fin through mechanical expansion. This helps to reduce the contact thermal resistance, resulting in an improved heat transfer efficiency.
After undergoing pressure testing, the product is then cleaned with trichloroethylene in the tube. This is to remove any oil, moisture, or oxide scale in the tube.
A special fan motor is used in the product. It is selected for its low power consumption, large air volume, low noise, and long range. This helps to ensure that the product can operate normally even under humid and low temperature conditions.
The product also features a U-shaped tubular stainless steel electric heating tube. This electric heating tube is inserted into the coil, with a reasonable spacing distribution and power design. As a result, the defrosting time is shortened, and the defrosting effect is improved.
The slot-type hanger is used for easy lifting of the product.
Finally, all products are nitrogen-filled and pressure-maintained before leaving the factory.

The DL, DD, and DJ types of cold storage units have varying temperature requirements for maintaining different types of perishable items. The DL type is ideal for storing fresh eggs or vegetables in cold storage with a temperature of around 0℃. This type of storage helps to keep the vegetables and eggs in their ideal temperature and humidity, thereby extending their shelf life and maintaining their freshness for a longer period of time.
The DD type, on the other hand, is suitable for refrigerating frozen foods such as meat and fish at a storage temperature of approximately -18℃. This type of cold storage unit helps to keep the frozen goods in optimal condition by preventing freezer burn and preserving the taste and texture of the food.
The DJ type of cold storage unit is perfect for quickly freezing meat or fresh fish products or prepared foods at a storage temperature of -25℃. This type of storage is especially beneficial for maintaining the quality and taste of the food during the freezing process. Using a DJ cold storage unit can help ensure superior quality food that retains its original flavors and nutrients even after being frozen.
