An empty trailer is arguably the “worst case scenario” because the cubic volume
of warm air is at a maximum. Even in this case, the temperature at the rear of the
trailer is approximately 10° F cooler than the same trailer without an FG Side Duct
A loaded trailer without an air chute(as in the case of SEFF) showed us that indirect
interference from product or turbulence limited the full length circulation necessary to
keep product at the proper temperature. 28.3 degrees is a large difference!
It should be noted that each test trailer was outfitted with a properly sized
refrigeration unit. Our test results do not indicate inadequate refrigeration unit
performance. In both cases it is important to remember that proper air circulation
and temperature control is only possible if the method used is consistent and reliable.
