D-series air cooler, also referred to as air cooler, is an essential device that provides efficient cooling for various cold storages, such as civil cold storage or combined cold storage. The D-series air cooler comes in three different types: DL, DD and DJ, all of which are suitable for cold storages with different storage temperatures.
One of the main advantages of the D-series air cooler is its compact structure, which makes it a space-saving device. In addition, it is light weight and designed to eliminate any cold storage area, which helps in maintaining a uniform storage temperature. This attribute ultimately leads to the preservation of the freshness of the stored food.
Another notable advantage of the D-series air cooler is its high efficiency in cooling down the food stored in the cold storage. With the use of this device, food can be quickly cooled down resulting in improved freshness and extended shelf life.
Using either a plastic spraying process or embossed aluminum plate, the shell of the product is designed to be resistant to corrosion and has an attractive appearance.
The coil arrangement is innovative in order to reduce wind side resistance. After the sheet is installed, the copper tube is mechanically expanded onto the fin to reduce contact thermal resistance and so improve heat transfer efficiency.
The product undergoes a pressure test before being cleaned using trichloroethylene in the tubing. This removes any oil, moisture and oxide scale from within the tubing.
Our specialized fan motor has low power consumption and is specifically designed to provide large air volume, low noise and a long range. This ensures that the product can operate normally under humid conditions and in low temperatures.
Our U-shaped tubular stainless steel electric heating tube has strong insulation and is inserted into the coil. We ensure that the spacing distribution and power design are reasonable to ensure that defrosting times are short and have a good effect.
The slot-type hanger we use makes for easy lifting so that the product can be transported easily and safely. All of our products are filled with nitrogen and are pressure-maintained before leaving the factory.

There are different types of cold storage units available for various purposes. The DL type is ideal for cold storage with a storage temperature around 0℃, mainly used for storing fresh eggs or vegetables. On the other hand, the DD type is appropriate for storing frozen foods, such as meat and fish, with a storage temperature of about -18℃. Lastly, the DJ type is designed for quick freezing of meat, fresh fish products, or prepared foods, with a storage temperature of -25℃.
