Type Standard air cooler DD-57.9/310
Product Features:
D series air cooler is a complete library of cooling cooling equipment freon refrigeration unit used;by the use of temperature to sub-divided into DL,DD,DJ three series,can be separately applied to different storage temperature ,DD type air cooler is mainly applied to the refrigerator of -18℃.
The series has the following characteristics:
1. The shell is made of high quality steel,powder coated,corrosion resistance,aesthetic appearance;
2. High-quality stainless steel electric heating tube evenly distributed in the coil,good defrosting effect, defrost using electric heating tube and finned aluminum casing hole close,easy to heat,long life;
3. Coil using the wrong row or parallel manner,using a mechanical expander, brass and aluminum so closely,good effect of heat transfer;
4. Cooler design width reasonable, blades and aluminum fin spacing is greater than 1/3 diameter of the blades to ensure there is enough effective air flow;
5. You can use long-range air duct according to customer requirements.
