1. According to international standards
The technical parameters of high-quality DC freezer are all in accordance with international standards, and the quality is guaranteed
2. The freezer has constant temperature and fast cooling speed
The working temperature of high-quality DC freezer is distinguished by the most suitable temperature for food storage or preservation. The DC freezer can ensure that the juice contained in food is not lower than the freezing point and keep its fresh state. High-quality refrigerators not only meet the requirements according to the standards, but also make the refrigeration speed of high-quality refrigerators faster by adopting special-shaped evaporation tubes and matching units with suitable refrigeration capacity.
3. Commercial high-power compressor
All DC freezers adopt commercial compressors. Commercial compressors have good starting performance, complete specifications of refrigerating capacity from small to large, and can be configured differently according to different requirements of products. Only commercial compressors can adapt to the harsh environment, frequent starting times and long running time of commercial refrigerators to ensure product quality. Although the price of commercial compressors is higher than that of domestic compressors, the failure rate is less than two thousandths.
4. The freezer material is better
All evaporation tubes of DC freezer are made of high-quality copper coils and processed into wide-face special-shaped tubes. The stainless steel plate has a smooth surface and uniform thickness. The proper thickness not only ensures a long service life, but also makes the appearance of the refrigerator smooth and firm.
5. The heat preservation effect of the freezer is better
In the production process of DC freezer, the thermal insulation performance of insulation layer is not only an important quality index of freezer, but also an important factor of economic use of freezer. In order to achieve good thermal insulation performance, it is necessary to select appropriate raw materials and control the bulk density and cell diameter in the best range.
6. The structure is stronger
The structural firmness of DC freezer is directly related to the service life. There is an integral angle steel frame support between the outer shell and the inner container of DC freezer, which is equivalent to placing steel bars in the cement precast slab, thus greatly increasing the firmness. After all the door frames are welded and formed, the whole body is foamed and formed at one time, thus avoiding the defect that the cabinet door is easy to fall off because the door frame is not firmly assembled.
