PureBlue Reefer Trailer
Stoughton's PureBlue™ refrigerated trailer is an innovative trailer that is more thermally efficient, lighter weight, and safer than other competitive trailers on the road today. The use of bonded side posts reduces the number of holes in the sidewalls to aid in preventing moisture intrusion into the trailer. Composite framing used in the front wall and rear doors optimizes thermal efficiency and reduces overall weight, letting you haul more product. Minimizing air loss with a triple wiper seal on the rear doors helps protect your cargo from the elements. Galvanized steel components provide greater protection from corrosion and extend product life.
PureBlue is the refrigerated trailer that sets a new industry standard for performance. In Q3 of 2025, Stoughton Trailers commissioned Element Labs to conduct an independent, third-party competitive testing to benchmark its PureBlue against five leading refrigerated trailers. The results showed that PureBlue was, on average, 18.2% more thermally efficient than the competitive set. The PureBlue design was also lighter than four of the five competitor trailers tested and, when compared directly to the market-leading trailer, delivered both superior thermal efficiency and lighter overall weight.
PureBlue refrigerated trailers are now available with the factory-installed equipment, allowing for multiple temperature zones within the trailer. Stoughton offers a heavy-duty, grocery spec flat floor for customers in food, pharmaceutical and other cold-chain markets.
