Precedent S-600RR
NewUnsurpassed reliability and double-digit fuel savings for rail refrigeration.
The Precedent S-600RR offers CARB Evergreen compliance, outstanding durability, and double-digit fuel savings for rail-ready refrigeration applications.

About Precedent S-600RR
The Precedent S-600RR is designed for robust performance in unattended rail service, offering extended maintenance intervals and expert mobile support nationwide. It ensures lower operating costs and the lowest cost of ownership, backed by the longest warranty in the rail industry. With CARB Evergreen compliance, it eliminates the need for a Diesel Particulate Filter (DPF) and provides superior temperature control with electronic fuel injection and real-time fuel monitoring.
Benefits
Lower Operating Costs
The SR-4 Controller with OptiSet® Plus ensures correct parameters are set for every load, quickly and easily. Extended maintenance intervals (EMI) mean longer periods between service. A low fuel warning helps prevent costly out-of-fuel shutdowns, and scheduled maintenance reminders keep the unit running at peak efficiency.
ConnectedSuite™ Telematics
Every Precedent rail refrigeration unit includes 24 months of complimentary TracKing telematics. This allows fleets to easily monitor and analyze refrigerated fleet operations, saving time and money on installation. Fleets can enable TracKing telematics remotely, gain access to data, and focus on their business without taking assets out of service.
e-Rail Safe Certified Dealers
e-Rail Safe certification is essential for accessing rail yards and facilities across the United States. Without it, access can be denied, leading to lost loads and customer dissatisfaction due to unit shutdowns. Thermo King dealers are e-Rail Safe certified, ensuring they can access all rail yards nationwide to provide timely service.
