Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for water vapor condensing units in gas drying
Equipment primarily for dehumidification classifies under vapor condensing machinery.
If imported as replacement heat exchanger parts
Individual heat exchanger components for cryogenic use fall under valves and regulators parts.
If when sold as a complete gas processing station
Multi-function gas stations not emphasizing liquefaction may go to other unspecified industrial machinery.
