At present, domestic freezing dryers are not much different from foreign importers in terms of hardware configuration. Refrigeration compressors, refrigeration accessories, and refrigerants use a large number of internationally renowned brands. The applicability of users in the freezing dryer generally exceeds the import machines. This is because domestic manufacturers in China have fully considered the characteristics of domestic users when designing and making a freezer dryer, especially climatic conditions and daily maintenance characteristics. For example, the power of the cooling compressor of the domestic freezer dryer is generally larger than the same specifications, which fully adapted to the characteristics of the vast vast and different seasons/different seasons. In addition, domestic machines are also quite competitive in terms of price, and they have an inevitable advantage in after -sales service. Therefore, domestic frozen dryers are very popular in the domestic market. At present, the gap between domestic frozen dryers and imported frozen dryers is mainly manifested in the level of manufacturing process, especially in terms of cleaning and assembly welding in refrigerant system pipelines. In addition, imports have now used a green environmentally friendly refrigerant R134A, which has no destruction of atmospheric ozone layer, which is still difficult to do on the domestic freezer dryer.
