Refrigeration units for transportation control the temperature inside the cargo compartment in order to maintain the quality of food and other cargo during shipping. These refrigeration units were planned with the objective of providing high-quality, reasonably priced refrigeration units to contribute to food safety and security. Until now, typical moldings imitated a front grille, but we reduced the feeling of intimidation by starting with a base with a geometrical shape that fits well with the box shape of the cargo compartment and by chamfering the sides. Furthermore, by placing our brand logo symbolically on the sides, we expressed high quality.
