The Precedent S-Series: The Only Evergreen Choice

Developed to achieve Evergreen CARB and EPA emissions compliance while adding performance, the Precedent S-Series is notable for what it does not have: a Diesel Particulate Filter (DPF). When considering the negative impact on engine life and fuel efficiency that a DPF brings, it was clear that a DPF was not a viable solution for units that run in California. Choose the S-Series and you’ll avoid the unknowns and risks of DPFs and can rest easy knowing that you’re running the only unit available that will be compliant nationwide for as long as you own it.

Precision Temperature Control

“Close enough” isn’t what your customers are looking for with their temperature-sensitive cargo. Your unit should perform as you program it to, which is just what Precedent units do. No magic, no averaging, just precise temperature control that helps ensure your loads arrive exactly as they should.

Eco-Pulldown

Thermo King’s entire line of Precedent refrigeration units offer proprietary eco-pulldown technology that can dramatically reduce fuel consumption. Eco-pulldown technology takes advantage of the efficient design of the Precedent refrigeration system.
