Minneapolis-based Thermo King designed a line of Precedent S-Series model transport temperature control systems to create peace of mind for refrigerated trailer Thermo King Precedentfleet operators and owner operators who want to remain compliant with air quality standards without sacrificing performance or efficiency.

The Precedent S-Series is said to deliver double-digit fuel savings, best-in-class performance and lower life cycle costs while providing regulatory compliance.

Within this platform is the Precedent S-600 unit, which meets the variety of refrigeration demands within the trucking industry thanks to its strong pull-down and 2-speed evaporator operation for exceptional airflow while hauling perishable goods.

This greater-than-25 horsepower, single-temperature unit is said to be the only unit in the industry compliant with California Air Resources Board (CARB) Ultra-Low-Emission Transport Refrigeration Unit In-Use Performance Standards (ULETRU), to meet Tier IV final emissions certification by the U.S. Environmental Protection Agency (EPA) and the only evergreen CARB compliant unit requiring no additional diesel particulate filters (DPF) or engine emissions system (EES).
