Simple plate fins, engineered for a press fit on the condenser tube, as in examples 1 and 3 were relatively easily achieved. The serpentine, soldered fin construction in example 2 represented a 2 nd or 3 rd generation of fin engineering, with higher conductivity and thermal performance. The manufacturing process for producing the fins and soldering them in place was a mark of the increasing sophistication of Canadian manufacturing methods, in place by the end of the 1930\u2019s. As manufacturing methods evolved the Canadian industry would move to non-ferrous tube and fin construction [copper], see code no. 6.02-7, and eventually to non-corrosive refrigerants, including methyl chloride and Freon 12. But for now this construction genre remained as the state of the art, an important snapshot in time.
