The Stoughton PureBlue refrigerated trailer sets a new standard for thermal efficiency, weight savings, and durability in cold-chain operations. Engineered with bonded side posts to reduce moisture intrusion and composite framing in the front wall and rear doors, PureBlue helps maintain consistent temperatures while reducing overall trailer weight, allowing fleets to haul more product with confidence.
Thermal Efficiency & Insulation
- Platen foaming insulation process applied to sidewalls, ceiling, front wall, doors, and floor for consistent, airtight insulation
- Bonded side post construction reduces rivet count by up to 704 per sidewall, helping limit heat flow and moisture intrusion
- Composite framing in the front wall and rear doors to optimize thermal efficiency without adding weight
- Composite refrigeration unit mounting frame designed to reduce heat transfer from the reefer unit into the trailer
Rear Door & Sealing System
- Lightweight composite rear doors designed to reduce weight while maintaining strength
- Triple wiper seal door gasket retains contact pressure for a longer-lasting seal
- Seal design minimizes air loss, prevents water intrusion, and is easily replaceable without full door disassembly
Floor & Interior Protection
- Fully enclosed, extruded aluminum heavy-duty duct floor for high-load support
- Standard heavy-duty non-skid floor with optional grocery-spec flat floor available
- No wood in the floor structure to increase service life
- Dual sidewall scuff protection:
- Rivet-free 6-inch aluminum scuff band
- 12-inch integral scuff liner providing 18 inches of total sidewall protection
Frame, Suspension & Weight Savings
- Hot-dip galvanized steel frame components, slider box, and rear underride guard for corrosion resistance
- Aluminum cross members (5.25-inch extruded) for a strong yet lightweight floor structure
- Standard Hendrickson ULTRAA-K® slider suspension, designed for an optimized strength-to-weight ratio
- Lighter overall trailer weight supports increased payload capacity
Safety & Compliance
- Rear underride guard comes standard with no additional cost or weight
- Designed to resist automobile intrusion at 30%–100% overlap
- Complies with applicable U.S. and Canadian regulations
- Bolt-on design allows for easier repairability
Performance Highlights
- Up to 13% greater thermal efficiency compared to industry average*
- Reefer unit run time reduced by up to 275 hours per year*
- Up to 560 lbs of weight savings* to help increase payload capacity
