Hexahedron Refrigerating Chamber System contains front, back, left, right, upside and downside, six planks in total, also named Hybrid Freezer. Application includes small-scale storage, which the hydraulic hand jacks and fork lifts are no accessible

The structure of Pentagon Refrigerating Chamber System is more sophisticated, which is particularly applied on RC material floor. Specifically, issues such as the collision of the access of fork lifts and the slippery floor for entrances and exits, should both be taken into consideration. Thus, equipping additional mechanical protections, electric heating floor and bumpers, is of a necessity.
