PureBlue Refrigerated Trailer

18.2% More Thermally Efficient Than Other Reefer Trailers

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 materials used in the front wall and rear doors optimize thermal efficiency and reduce 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.

Why PureBlue™ Refrigerated Trailers Set a New Industry Standard

PureBlue is the refrigerated trailer that sets a new industry standard for performance. In Q3 of 2025, Stoughton Trailers commissioned Element Labs to conduct independent, third-party competitive testing to benchmark its PureBlue against the five leading refrigerated trailers. The results showed that PureBlue was, on average, 18.2% more thermally efficient and 27.7% more airtight than the competitive set. The PureBlue design was also lighter than four of the five competitor trailers tested. When compared directly to the market-leading trailer, PureBlue delivered both superior thermal efficiency and lighter overall weight.

Refrigerated Trailers Built for Cold-Chain Markets

PureBlue refrigerated trailers are available with 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.

Frequently Asked Questions

What is a reefer trailer? A reefer trailer (short for refrigerated trailer) is an insulated semi-trailer equipped with a refrigeration unit that maintains a controlled temperature during transport. It’s used to carry temperature-sensitive goods such as food, pharmaceuticals, and other perishable products.

How is a refrigerated trailer different from a dry van trailer? A refrigerated trailer actively controls temperature using a built-in cooling system, while a dry van trailer does not. Dry vans are used for non-perishable freight and simply protect cargo from weather and theft, whereas reefer trailers are insulated and designed to keep goods cold or frozen.

Which industries use refrigerated trailers? Refrigerated trailers are commonly used by:

  • Food and beverage companies (produce, meat, dairy, frozen foods)
  • Pharmaceutical and medical suppliers
  • Floral and agricultural businesses
  • Chemical manufacturers
  • Retailers and grocery distributors
