Description
The Thermo King Precedent C-600 single-temperature trailer refrigeration unit delivers outstanding efficiency, temperature control, and long-term reliability. Built on an innovative Diesel Direct Electric (DDE) architecture, the C-600 maximizes fuel savings while minimizing energy loss compared to all-electric alternatives.
Emissions and Compliance
Engineered for full regulatory compliance, the C-600 achieves CARB Evergreen status without requiring a Diesel Particulate Filter (DPF). The four-cylinder direct injection engine meets EPA Final Tier 4 emissions standards, ensuring lasting compliance for fleet operations.
Advanced Cooling & Component Architecture
- Condenser System: Features microchannel condenser coils with a curved design that more than doubles surface area, improving airflow and eliminating operational dead spots.
- Reciprocating Compressor: Powered by the proven X430 series compressor featuring an aluminum alloy body for durable, high-efficiency refrigeration.
- Dual-Speed Evaporator: Utilizes smart induction fans to optimize airflow across varying engine speeds, delivering an airflow capacity of up to 3,350 cu. ft./min.
- Control & Diagnostics: Equipped with the Smart Reefer SR4 controller, temperature data logging, pretrip diagnostics, and integrated TracKing telematics for real-time fleet asset tracking.
Service & Maintenance
Designed to minimize downtime, the system features a 3,000-hour standard maintenance interval, composite easy-access door panels with auto-latches, and heavy-duty drive belts engineered for extended life.
