Fleet managers often overlook environmental considerations when seeking temporary refrigerated trailer solutions. Sonsray Rentals & Leasing prioritizes both equipment reliability and ecological responsibility, with trailers that receive meticulous maintenance and equipment that functions dependably for transporting temperature-sensitive cargo.
The company distinguishes itself by installing only environmentally safe refrigeration equipment across its entire fleet. Specifically, Sonsray has chosen Thermo King Precedent S-Series units — representing cutting-edge transport refrigeration technology with the lowest environmental footprint available.
The fleet achieves 100% CARB Evergreen Certification and EPA Emissions Compliance. California's stringent emission standards guided this decision: meeting those requirements ensures compliance nationwide. Customers also benefit from double-digit fuel savings over extended routes without requiring diesel particulate filters.
Sonsray commits to reducing environmental impact as a core business strategy, pledging to continuously install advanced refrigeration systems and demonstrating leadership while encouraging industry-wide adoption of cleaner alternatives.
