Thermo King SL-200 Trailer Refrigeration Unit

The Thermo King SL-200 is the mid-capacity model in the SL trailer family and the diesel-only counterpart to the SL-200e. If a trailer never plugs in, there is no reason to pay for a standby motor, and the SL-200 is the version for exactly that operation — line-haul work where the trailer is either rolling or parked away from power. Listed at $8,500. Thermo King SL-200 Specifications Type: single-temperature nose-mount trailer refrigeration unit Power: diesel only (no electric standby fitted) Engine: Thermo King four cylinder direct injection diesel Drive: belt-driven open compressor Control: Thermo King microprocessor with programmable setpoints Modes: continuous run and cycle-sentry, automatic defrost Application: chilled and frozen freight in 48-53 ft vans Condition: new and inspected used units available Price: $8,500 Cycle-Sentry and Continuous Run Continuous run keeps the evaporator fans turning all the time, which gives even air distribution and tight temperature control — the right mode for fresh produce that needs airflow as much as it needs cold. Cycle-sentry starts and stops the engine to hold setpoint, which uses far less fuel and is the right mode for frozen freight that does not care about airflow. The wrong mode for the commodity is one of the most common causes of a load claim, and it costs nothing to get right. Applications Long-haul chilled and frozen freight, produce, protein and dairy, and fleets that want the SL platform’s simplicity without paying for standby capability they cannot use. If your trailers do dwell at powered docks, the SL-100e or SL-200e will pay the difference back in fuel.
