Thermo King SL-200 Trailer Refrigeration Unit

The Thermo King SL-200 is a robust, diesel-only refrigeration unit designed for the demands of line-haul trailer operations where electric standby power is not utilized. This mid-capacity model offers flexibility with both Continuous Run and Cycle-Sentry modes. Continuous Run ensures consistent airflow and precise temperature control, ideal for sensitive produce, while Cycle-Sentry optimizes fuel efficiency by automatically starting and stopping the engine to maintain setpoints, perfect for frozen goods. Featuring a Thermo King four-cylinder diesel engine and microprocessor control, it provides reliable performance for chilled and frozen freight in 48-53 ft trailers.
