1. What are the characteristics of domestic cold dryers compared with imported cold dryers?
At present, the hardware configuration of domestic cold dryers is not much different from that of foreign imported machines. Refrigeration compressors, refrigeration accessories and refrigerants all use a large number of international famous brands.
The user applicability of cold dryers generally exceeds that of imported machines. This is because domestic manufacturers have fully considered the characteristics of domestic users, especially the climatic conditions and daily maintenance characteristics, when designing and manufacturing cold dryers.
For example, the power of refrigeration compressors of domestically produced cold dryers is generally larger than that of imported machines of the same specification, which fully adapts to the characteristics of my country’s vast territory and large temperature differences between regions/different seasons.
In addition, domestic machines are quite competitive in price, and have incomparable advantages in after-sales service. Therefore, domestic cold dryers are quite popular in the domestic market.
At present, the gap between domestic cold dryers and imported cold dryers is mainly reflected in the production process level, especially in the cleaning of refrigerant system pipelines, assembly and welding. In addition, imported green refrigerant R134a, which has no damaging effect on the atmospheric ozone layer, is now commonly used, which is still difficult to do in domestic cold dryers.
2. What are the characteristics of the cold dryer compared with the adsorption dryer?
Compared with adsorption drying, freeze dryer has the following characteristics:
① There is no gas source consumption. For most gas source users, using a cold dryer saves energy compared to using an adsorption dryer;
② No wear of valve p
