With the development of production, they are gradually replaced by artificially controllable heat sources and air dehumidifiers.

[0003] For example, the authorization announcement number "CN204684922U" is an air dryer, which dries the compressed air very well. After long-term use, it can absorb moisture in the compressed air normally as long as it is electrically heated for a period of time. However, part of the heat is lost to the air outside the electric heating coil, resulting in a waste of resources; at the same time, the air that still has residual moisture after drying is not processed.
