TESTING PROGRAM FOR DETERMINING EFFICIENCY OF REFRIGERATED TRAILERS (CONTAINERS)

Since the early '60's, trailers have been insulated with Polyurethane foam. This insulation was theoretically twice as effective as previously used insulations. In application it became apparent that Polyurethane foam had certain drawbacks. Improper mixes of liquids making the foam resulted in imperfect cell structure allowing moisture entrance, and improper mechanical application of the foam in the trailer could result in unisulated areas which were not readily discovered. In the early '60's there was no certain means of determining Polyurethane foam efficiency as applied in a trailer. Later, standards of efficiency and an independent testing laboratory to determine trailer efficiency were established.
