A cold chain logistics solution which facilitates low operating cost was developed by the team FreshUnn Technologies from the Department of Mechanical Engineering, IIT (Madras). Unlike the conventional diesel powered method, this technology is electrically powered thus rendering the system as environmentally benign. It’s a key aspect is the unique ‘Thermal Battery’ that can retain the cooling for 3 to 4 days with one single charge. This comprises of a charging unit and a battery system. Once the system is charged for 6 to 8 hours, it can retain the cooling for 3 to 4 days. Furthermore, the system does not require any active cooling during transportation thereby reducing the fuel requirement. With further research the system can be coupled with solar panels to make it completely environmentally friendly, thus facilitating a reduction in the carbon footprint.
