Benefits

Proven Emissions Compliant

Utilizing the proven S-Series engine, the S-750i meets current and proposed CARB ULETRU emissions without the use of a DPF. Integrated shore power, embedded telematics with 24 months of service, and R452A refrigerant position this unit well for future regulatory changes.

Why do you need shore power?

Benefits of Shore Power Operation include increased efficiency (4x more efficient than diesel), reduced environmental impact (fewer emissions), quieter operation (at least 3 decibels quieter), less maintenance, and longer TRU life due to extended engine maintenance time frames.

Use telematics to increase your profitability

Telematics data helps your fleet be more responsive by providing immediate issue detection, monitoring temperature, offering rapid alarm detection, security alerts for door openings, and detecting fuel loss. Every S-750i unit comes equipped with ConnectedSuite™ telematics, providing 24 months of complimentary service.

Keeping sustainability at the forefront

By purchasing an Evergreen CARB compliant unit, customers meet the strictest Particulate Matter and NOx regulations and maximize fuel usage. Since 2013, Precedent S-Series units have avoided over 6 million metric tons of CO2 emissions, contributing to Trane Technologies’ Gigaton Challenge to reduce customer greenhouse gas emissions by 1 billion metric tons.
