Thermo King's new Advancer S-DRC slimline rail unit for cargo rail and intermodal applications meets current California Air Resources Board Ultra-Low Emission Transport Refrigeration Unit (ULETRU) emissions standards, making it compliant in all 50 states.

Using the company’s S-Series engine, the S-DRC will replace the SLXi-DRC.
“The Advancer S-DRC is another example of Thermo King’s commitment to delivering smart, sustainable temperature-control solutions that help customers transition fleets to reduce their environmental impact and be compliant with the changing regulations in California,” said Sam Doerr, Thermo King’s trailer portfolio leader.
Thermo King said the enhanced efficiencies of the Advancer S-DRC not only allow customers to keep sustainability at the forefront of their business but also can help lower their total cost of ownership. This, according to the company, is accomplished through:
10% improved fuel efficiency over the previous generation.
Next-generation control system that enables precise temperature management.
A slimline profile that allows a competitive 15-pallet capacity and enables a smooth transition to over-the-road, simplifying cross-docking operations.
Two ThermoLite solar panels as standard.
Integrated shore power.
Every Advancer S-DRC unit will also come equipped with TracKing telematics to deliver the data, and there will be no service charge for the first 24 months of ownership. The telematics can help fleet owners monitor temperature, offers rapid alarm detection and security alerts when the doors are opened, and helps detect fuel loss. Additionally, it provides access to predictive analytics and performance dashboards.
Thermo King said the Advancer S-DRC aligns with customers’ goals to transition to more sustainable solutions for their fleets and supports the company’s commitment to reducing carbon emissions and advancing Trane Technologies’ 2030 Sustainability Commitments.
“Our portfolio has expanded significantly in the last year, and Thermo King is committed to having a low- or zero-emission solution in every segment of cold chain transportation,” said Chris Tanaka, vice president of product management for Thermo King Americas. “We are accelerating solutions that help decarbonize the cold chain and support our customers who need solutions that meet regulations and their lower-emission targets.”
