Reefer Trailer

The reefer trailer uses a foam-injected insulated panel body rated to hold set temperature from minus 25C to plus 25C, running on a diesel refrigeration unit mounted at the nose. Insulation thickness and panel sealing are the two specs that matter most for buyers comparing semi reefer trailers for sale, since a poorly sealed door or thin wall panel loses cold faster than any compressor can recover, driving up fuel burn. Frame is Q345B steel with a corrosion-resistant coating under the floor where condensation and cargo runoff collect. We build multi-temperature zone options for operators hauling frozen and chilled goods in the same load, plus rear swing doors or roll-up doors depending on dock access at the buyer's usual delivery points.

Insulation and Sealing Decide Real-World Performance

Buyers searching for semi reefer trailers for sale, whether new or among used semi reefer trailers for sale, usually compare refrigeration unit brand first, but panel insulation and door seals matter just as much for actual fuel cost and temperature hold. Buyers cross-shopping a 2023 Utility reefer trailer price or any other North American brand's sticker price against SIGMA's factory quote generally find the insulation and refrigeration spec comparable at a lower landed cost for export markets. Our body uses foam-injected panels sealed at every joint, holding cargo temperature from minus 25C for frozen goods up to plus 25C for chilled produce without the compressor running constantly. Fleets that also move dry freight on the same routes often add our Flatbed Trailer for backhaul legs where refrigeration isn't needed, since it shares the same tractor and axle spec.

Multi-Temperature Zones for Mixed Cargo Routes

Distribution routes rarely carry a single product type, so we offer a partitioned reefer trailer body that splits the interior into two temperature zones, letting one truck deliver frozen goods to one stop and chilled dairy to the next without cross-contaminating temperature settings. Partition walls are removable for operators who need full-length single-zone capacity on other routes. This flexibility matters most for regional distributors running mixed grocery or foodservice delivery rather than dedicated frozen-only lanes.

Built for Daily Loading and Washdown

Floor is anti-slip aluminum tread plate rated for daily pallet jack and forklift traffic at distribution centers, and the under-floor structure carries a corrosion-resistant coating since condensation drip and cargo runoff are constant in cold chain operation. Door seals and hinges are sized for frequent opening at multi-stop routes without losing the gasket seal that keeps cold air inside. Operators expanding into oversized refrigerated cargo, like palletized machinery needing climate protection, sometimes pair this unit with our Lowbed Trailer for the non-perishable side of their fleet. Fleets outgrowing a single semi truck reefer trailer for sale, and buyers who'd otherwise be scanning a reefer trailer for sale by owner near me listing hoping to save on a used unit, get a full size reefer trailer built to the same insulation and door-seal spec on every unit we ship, rather than an unknown history from a private seller.
