Reefer

A reefer (short for refrigerated trailer) is an insulated semi-trailer equipped with a built-in refrigeration unit that maintains a specific temperature range during transport. Reefers can hold temperatures from -20F to 70F, making them essential for transporting perishable goods including fresh produce, frozen foods, meat, dairy, beverages, pharmaceuticals, and certain chemicals.

Reefer trailers are more expensive to purchase ($50,000-$80,000 new versus $30,000-$50,000 for a dry van) and cost more to operate due to fuel for the refrigeration unit (an additional $0.15-$0.25/mile). However, reefer rates are consistently higher than dry van — averaging $3.10/mile with professional dispatch. The premium rates reflect the higher operating costs, stricter handling requirements, and the risk of cargo spoilage.

Reefer hauling requires more attention to detail. You must pre-cool the trailer before loading, maintain continuous temperature records (using devices like TempTale or Sensitech), and verify temperature settings match the shipper requirements. Temperature excursions — even brief ones — can spoil an entire load worth $50,000-$200,000, leaving the carrier potentially liable for cargo claims.
