Answer: Common cold dryers are divided into air-cooled and water-cooled types according to the cooling method of the condenser; they are divided into high-temperature air-intake type (below ) and normal-temperature air-intake type (around) according to the intake air temperature; they are divided into ordinary type (0.3~1.0MPa) and medium and high-pressure type (above 1.2MPa) according to the working pressure. In addition, many special specifications of cold dryers can be used to treat non-air media, such as carbon dioxide, hydrogen, natural gas, blast furnace gas, nitrogen, etc.
