The 1950\u2019s and on into the 60\u2019s was the \u201cgolden age\u201d of the open-system refrigeration machine. Behind the industry were its crude beginnings in Canada. Machines were now operating on non-noxious refrigerants [principally F12], were smaller, lighter, quieter, more efficient and reliable.As important was the fact that they were readily field serviceable, allowing major components to be removed for repair or replacement. Too, major component replacement was facilitated, even with parts of a different manufacture, because of the level of universality and flexibility, which was an inherent part of the open-system design, a feature which would soon be lost, as the industry moved to higher efficiency, less costly sealed system design.<\/p>","protected":false},"excerpt":{"rendered":"
