Thermo King introduced the Precedent S-750i trailer refrigeration unit for long-haul and local food distribution.
Utilizing the S-Series engine, the S-750i meets current and proposed California Air Resources Board Ultra-Low Emission Transport Refrigeration Unit emissions without the use of a diesel particulate filter.
Electrification, integrated shore power, embedded telematics, and a lower-global warming potential refrigerant all contribute to Thermo King’s efforts in helping customers transition fleets to reduce their environmental impact and stay ahead of future regulation, company officials said in a press release.
The enhanced operational efficiencies of the S-750i leverage Thermo King’s Precedent platform and introduce several new first-use features. These include a three-speed engine, which optimizes efficiencies at fresh and frozen; a next-generation control system, which offers precise temperature control; and a diesel electric architecture optimized for shore power integration, which makes the S-750i an “ideal investment” for fleets using or considering shore power operation long-term.
Shore power operation is up to four time more efficient than diesel, has fewer emissions than diesel, is at least three decibels quieter than diesel motor operations, reduces engine hour operation, and offers extended engine maintenance time frames, according to the company.
The S-750i trailer unit also comes equipped with TracKing telematics and collects data for the first 12 months of ownership with no service charge. Telematics can help fleet owners monitor temperature, offers rapid alarm detection and security alerts when the doors are opened, and detects fuel loss.
