Description
A Thermo King Precedent S-700, the deep-frozen single-temperature trailer unit of the Precedent line: 68,000 BTU per hour at a 35 degree box and 25,000 at minus 20, with no particulate filter.
The engine is a four-cylinder, direct-injection, liquid-cooled diesel rated at 35 hp, meeting EPA and CARB Tier 4 final without a diesel particulate filter. It drives an X430 reciprocating compressor with a 30 cubic inch displacement and a 14.5 lb charge. A Smart Reefer 4 controller with data logging and USB download manages the system, and the filtration is laid out for a 3,000 hour service interval, 4,000 with the severe-duty package.
The unit weighs 1,872 lb and measures 81.6 by 86.2 by 24 in. Prices run $13,500 to $21,000 across new and used. The source text named two different engine codes, so we confirm the engine model from the plate on the unit you buy.
