Characteristics and performances

A,It is made of quality copper tube and aluminum fin.Rust-proof coating treatment is performed on the casting. 

The product features reasonable structure, high heat transfer efficiency, equal frost, energy saving, low operating cost and simple installation.

B, Efficient fan featuring large air volume ,long shot range, and low noise enjoys a long life span.

C, Automatic molding process ensures dry clean interior of copper tube.

D, Having passed 2.6mpa air tightness test, the coil satisfies the requirements for tightness. Close conjunction of aluminum fin and copper tube achieves a good effect of heat transfer.

E, Electrical defrosting selects stainless tube-shaped electric heating tube featuring extreme high insulation performance, reasonable distribution, short time of defrosting and excellent effect. Water defrosting adopts special showering design to prevent splattering.

F, Famous brand fan and electric heating tube feature stable quality, low noise, low power consumption and high efficiency.

G, It is the wise choice for refrigeration project.

 

(1)Panel and side plates are well constructed by using step structure, reducing the noise caused by fan and fan vibration. Water pan and side plate are easy to dismantled.

(2)After treatment of phosphate and surface spray, the shell becomes corrosion resistance, smooth and achieves a long life span.

(3)Automatic molding process ensures dry and clean interior of the copper tube.

(4)2.6mpa air tightness test satisfies product air tightness requirements.

(5)Expanded by liquid pressure machine, the aluminum fin and copper tube are combined tightly and achieves a stable effect of heat transfer.

(6)Famous brand fan and heat tube achieves stable quality, low noise, less energy consumption and high efficiency.

(7)Slot type rack design convenient for installation.

(8)All wires and plugs are connected in an electrical box, convenient for installation and maintenance.

(9)Electric defrosting selects high insulation performance stainless steel heating tube. Reasonable distribution achieves short time defrost, high efficiency and low consumption.

Users can add module in the controller to achieve the automatic defrosting control.

Fast efficient defrosting and less energy cost.

Advantages: 

D series air coolers include DL, DD, DJ types and are applied in all ranges of cold room due to compact structure, lightweight, space saving.

Compared to the normal flow unit cooler, it can rapidly fast cool down temperature and greatly improve products freshness.

 

Application

D serial air cooler can match with different capacity condensing equipments; it can apply to different temperature cold rooms.

DL serial can apply to 0°Ccold room, storage such as egg or vegetable.

DD apply to -18°C cold room, storage meat, fish.

DJ apply to -25°Ccold room for freezing or fast freezing the fresh meat and fish.
