38 | Overdrive | June 2018 A sampling of reefer specs B uying a refrigerated trailer means considering a lot more specifi cations than with a dry van or fl atbed. There's duct design, UV-resistant roofs and the type and density of foam insulation, to name a few. Also, transportation refrigeration unit manufacturers are introducing greener models with higher operating efficiencies and lower fuel consumption. Combined with trailer makers off ering improved in- sulation and heat isolation on their reefer products, owners benefi t from lower TRU operating costs. The following are standard or typical specifications for popular 53-foot refrig- erated trailers.
