Description
The Thermo King Precedent® S-600 trailer refrigeration system sets the benchmark in transport refrigeration technology. Designed with a Diesel Direct Electric (DDE) architecture, the S-600 provides double-digit fuel savings while optimizing temperature control and minimizing energy loss across operations.
As a CARB Evergreen certified unit, it delivers full nationwide emissions compliance without requiring a Diesel Particulate Filter (DPF). Equipped with common rail fuel injection, microchannel condenser coils, and a high-efficiency reciprocating compressor, the S-600 maximizes thermal performance and equipment longevity.
