• The Supra® S8 Unit – When you need a reliable solution for refrigerated transport of perishable and frozen foods in large-medium to large trucks, you need a unit you can trust. The Supra® S8 unit delivers the powerful performance, capacity, and efficiency you’ve come to expect from a name that’s been trusted for decades. We’ve taken one of the industry’s most proven diesel truck refrigeration platforms and made it leaner, smarter, and filled with powerful advantages for fleets of all sizes.
• Innovative Design – Not only does the new Supra® S8 unit look great on the outside with its aerodynamic body and sleek composite paneling, but the internal systems have also been redesigned to make it lighter, quieter and more efficient.
• APX™ Control System – Powered by the latest operating system that combines remarkable control intelligence, temperature control and system reliability with amazingly simple operation for drivers, fleet managers and warehouse personnel.
• Lower-Noise Performance – Up to 3dbA quieter than our prior model on the base truck unit. Additional sound reduction available with the optional Stealth™ kit.
