Most problems are process oriented, not mechanical, Leshuk points out. "Every time we do a thermal map, whether it's for a trailer or a facility, we find opportunities for improvement. Quite often, especially when the facilities are older, people tend to blame temperature problems on the mechanical refrigeration system, but we find that the problems relate more to the process of how that trailer or facility is being operated," he says.
"We usually find that employees are leaving doors open too long, or insulated panels have been damaged or that there's not proper air circulation'particularly when we're talking about trailers. We see wall damage from forklifts in trailers or bad seals. Loading patterns are very important in trailers'that's often overlooked."
Thermal mapping projects start around $10,000, depending upon the size and complexity of a facility, as well as the length and the number of stops on a truck run.
