PRECEDENT MULTI-TEMP

The most environmentally sensitive multi-temp unit we’ve ever made offers improved efficiency and a lower cost of ownership.

With Precedent Multi-Temp’s architecture, we scrutinized everything. Components were meticulously researched, compared and optimized. In some cases, we made substantial upgrades. In other cases, we improved what already works.

And in the end, we arrived at a system that delivers superior temperature control and pull-down performance while helping provide double-digit gains in fuel efficiency.

The most environmentally sensitive multi-temperature diesel-powered unit we’ve ever made. A redesigned architecture. Unequaled reliability. It all adds up to double-digit fuel savings and a lower lifecycle cost.

Our Most Fuel-Efficient Unit Ever
Precedent pays for itself in approximately seven years of use.

Electronic Throttling Valve (ETV)
A standard feature of Precedent Multi-Temp, the ETV uses a microprocessor to precisely control the refrigeration system to save you both time and fuel during pull down.

Common Rail Fuel Injection
Meets all known emissions standards without the need for an expensive after treatment system.

Comprehensive Support
Every Precedent unit is backed by the Thermo King Dealer Network with over 200 locations across North America.

PRECEDENT S-600 AND S-700

The Precedent S-Series features a >25 horsepower engine with emission control technologies that minimize fuel consumption and deliver lifelong emissions compliance.

Developed to achieve emissions compliance, the Precedent engine is notable for what it does not have: a Diesel Particulate Filter (DPF). Because of the way a transport refrigeration unit (TRU) runs, with its frequent stops/starts, light engine loads and low exhaust temperatures, using a DPF to achieve compliance is problematic. When we also considered the negative impact on engine life and fuel efficiency that a DPF brings, it was clear that a DPF had no place in the Precedent platform.

To control emissions, we chose proven technologies that are ideally suited to TRU operation. The high pressure common rail fuel delivery system controls particulate matter within the cylinder while improving efficiency and performance.

Our “EGR Light” system recirculates a small amount of exhaust back into the combustion chamber in certain load conditions to help control NOX emissions. A unique “fail closed” design assures continued peak engine performance if a failure occurs, ensuring load integrity is maintained. Additionally, the Diesel Oxidation Catalyst (DOC) provides maintenance-free performance for the life of the unit.
