Evergreen CARB Compliant Solutions

Celebrating the Precedent® S-Series reefer unit

Celebrating the Precedent® S-Series reefer unit

At Thermo King, we are celebrating our history of investing in innovative and sustainable solutions that provide peace of mind and confidence for our customers.

The S-Series was the first reefer unit in the refrigerated transportation industry to achieve Evergreen CARB and EPA Tier 4 engine compliance. More than 10 years later, it's still a proven solution that meets the strictest emission regulations without modifications like a diesel particulate filter (DPF).

Your trust in us over the last decade for CARB-compliant solutions keeps pushing us to innovate and develop new solutions for you.

Innovative thinking is what drives us

Precedent Decade Celebration Landing Page Innovation Updated 2.0

When you're committed to providing your customers with reliable TRU solutions, smart thinking and innovation are a must.

Since launching the Precedent S-Series reefer unit, we've spent the last decade innovating to provide reliable, proven and industry leading technology. From more multi-temp options, solar integration and being the first TRU manufacturer to switch to a lower global warming potential (GWP) refrigerant, we are proud of the evolution of the Precedent S-Series portfolio.

We promise to continually provide new, reliable solutions that keep improving and pushing the boundaries of the transport refrigeration industry.

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.
