DENSO Corporation and Yamato Transport Co., Ltd. have co-developed D-mobico,*1 a compact mobile refrigerator. Yamato Transport began using D-mobico in its delivery trucks in February 2021. DENSO will market the product more broadly through DENSO Solution Japan Corporation by summer 2021.

As e-commerce grows, there is increasing demand for delivery systems that can move sensitive products, such as food and pharmaceuticals, more securely, at a controlled temperature and with less environmental impact. These characteristics are even more important to organizations transporting small parcels of chilled and frozen products, another rising trend. On the other hand, many delivery vehicles are unrefrigerated and require dry ice to move cold products. A more efficient and sustainable delivery method is needed.

One solution to this dilemma is D-mobico, a compact, lightweight and portable refrigerator compatible with a variety of thermal boxes depending on cargo size and amount. Powered by a mobile battery, D-mobico does not require dry ice, nor does it draw energy from the engine, to refrigerate its freight. This helps reduce CO2 emissions and improves the vehicle’s fuel efficiency. Such a system also supports the transition to electric delivery vehicles, a key development in creating cleaner transportation.

In addition to striving to make mobility greener for all, DENSO aims to achieve carbon-neutral manufacturing by reducing CO2 emissions from its products and plants, and by collecting and reusing CO2 in the atmosphere. Meanwhile, Yamato Transport has been working to reduce the use of dry ice and shift its fleet to electric vehicles in order to reduce the environmental impact across its operations. DENSO and Yamato Transport will continue working together to achieve safe and environmentally friendly delivery of chilled and frozen parcels.
