Carrier Transicold has added three models to its next-generation Supra series of diesel-powered truck refrigeration units for small to large box trucks ranging from 10 to 28 feet in length. Joining the initial Supra S6 model are the S7, S8 and S9 models, all built for less weight and to deliver improved cooling capacities more efficiently while using less fuel and refrigerant and reducing sound output, making them suitable for nighttime urban deliveries. When parked and operating on electric standby power, the lineup is engineered to deliver refrigeration capacities that rival their capacities when engine-driven. The platform’s architecture streamlines the refrigeration system into a configuration using 42% fewer unique components than earlier models, and to reduce service requirements further, the series feature maintenance-free fans and upgrades designed to enable the oil-service interval to be extended by 33% to 2,000 hours. A wrap-around honeycomb grille provides a more contemporary appearance and is removable for easy access to internal components.
