Benefits of the Precedent S-610M


Use telematics to increase your profitability

Telematics data is all about helping your fleet be more responsive. Knowing immediately when an issue occurs makes you more effective in how you respond—keeping your deliveries on time and avoiding load loss.

It also helps monitor temperature, offers rapid alarm detection and security alerts when the doors are opened, and detects fuel loss.

With ConnectedSuite™ telematics, you have the information you need at your fingertips. Every S-610M unit comes equipped to deliver the data you need, and does so for the first 24 months of ownership with no service charge.*

*One year of service at 15-minute reporting interval when unit is on and 60-minute reporting interval when unit is off, including two-way control functionality. Additional charges may apply.

Since the Precedent S-Series reefer unit launched in 2013, customers have avoided more than 6 million metric tons of CO2 emissions

Keeping sustainability at the forefront

Sharing a commitment to sustainability with our customers is what drives us forward. By purchasing an Evergreen CARB compliant unit, customers can rest assured that they are meeting the strictest Particulate Matter, NOx regulations, as well as maximizing their fuel usage. Since the Precedent S-Series reefer unit launched in 2013, customers have avoided more than 6 million metric tons of CO2 emissions. This saves the equivalent emissions of 600 million gallons of diesel fuel.

While transformational products like the Precedent S-Series help you make a positive impact on the environment, we also are committed to broader global climate goals. Through Trane Technologies’ Gigaton Challenge, we are committed to reducing our customer’s greenhouse gas emissions by 1 billion metric tons.
