At Intermodal Europe 2013, Carrier Transicold commemorated the 45th anniversary of the invention and production of its first “picture frame” container refrigeration system while looking ahead to its next milestone, the production of its one millionth unit.

Carrier’s original front-wall container refrigeration system was produced in 1968 and became the industry standard. With its flat, square frame, that first self-contained system fit compactly on the front wall of a corrugated steel insulated shipping box, giving rise to the nickname “picture frame” unit.

It took Carrier 25 years to reach the 100,000-unit plateau. With steady growth in the container industry over the past 20 years, Carrier’s output increased ten-fold, onto the present course to producing its one-millionth unit.

Carrier Transicold offes a complete line of equipment for refrigerated trucks, trailers and containers, and is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX).
