Description
The Thermo King Precedent® S-700 trailer refrigeration unit sets the standard for single-temperature transport refrigeration with deep-frozen capability. Built with a Diesel Direct Electric (DDE) architecture and electronic fuel injection with electronic throttling valve (ETV), it delivers reliable temperature control alongside double-digit fuel savings.
Engineered for nationwide longevity, the S-700 features an evergreen CARB and EPA Final Tier 4 compliant engine without requiring a Diesel Particulate Filter (DPF). The advanced microchannel condenser coil system maximizes heat transfer surface area to prevent airflow dead spots, while the proven 4-cylinder reciprocating compressor ensures durable, high-efficiency cooling in demanding ambient conditions.
