Mexican group ISA Tracto C revealed that it has developed a clean refrigeration technology for tow containers. Using sunlight and kinetic energy, the system would save up to at least 20,000 liters of fuel per year and reduce the costs of transportation operations.
Two prototypes have already been tested in the State of Mexico. The automated container system allows the cooling engines to run on solar energy through panels. The technology has the potential to store up to a hundred hours of solar energy. An auxiliary battery supplied with kinetic energy (from the movement of the tires when the tractor is on the road) takes over when the main power supply is reduced to the capacity of 30%.
According to Nayeli Flores Huerta, project leader, this container technology has great potential. In addition to declining costs for carriers, this process could open up primary markets such as the food and pharmaceutical industries.
"The automated container system allows the cooling engines to run on solar energy through panels. Another advantage is that, after the initial investment, there will be no fuel costs," he added.
