Compared to dry-van trailers, refrigerated trailers offer more to consider when spec’ing – the type and density of foam insulation, duct design and UV-resistant roofs, just to name a few details. As today’s transportation refrigerated unit manufacturers introduce models with higher operating efficiencies and lower fuel consumption, trailer manufacturers are offering improved insulation and heat isolation on their refrigerated products, resulting in lower TRU operating costs and greater savings for refrigerated carriers.
The following are standard or typical specifications for popular 53-foot refrigerated trailers marketed by leading suppliers. Look for specs of flatbeds in July. Specs of select dry vans appeared in March, but Stoughton Trailers’ dry van models were inadvertently left out; those appear this month on page 88.
