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.

Every Precedent trailer refrigeration unit comes Connected from the factory powered by TracKing, making it easier for fleets to monitor and analyze their refrigerated fleet operations. Fleets can save time and money on installation and choose to enable TracKing remotely, gain access to data, and focus on their business without having to take their assets off the road. Also, fleets can access data for temperature traceability and FSMA compliance while gaining insights into the performance of their refrigeration units.
