The 3.4m length closed box is specially designed for pickup or light truck chassis, mainly used for short-distance cold chain material transportation. It can accurately maintain the low-temperature environment inside the box, effectively ensuring the freshness and quality of perishable goods such as fresh food, aquatic products and pharmaceuticals during transportation. In addition, its overall size and load-bearing design are fully matched with the loading capacity of pickup trucks and light trucks, which can avoid problems such as unbalanced center of gravity caused by improper matching, and further ensure the stability and safety of the transportation process.

TOPOLO – CKD/SKD/CBU refrigerated truck body manufacturer
TOPOLO offers refrigerated truck bodies that can be towed by any simple pickup truck or sedan. These coolers come in sizes of 5, 6, 8, and 12 feet. They feature a fiberglass shell and are available with PU or XPS insulation.
Rapid assembly improves efficiency
The modular refrigerated box feature a quick-assembly structure that allows for installation and disassembly without specialized tools, reducing labor time and improving assembly efficiency. Traditional refrigerated box assembly typically requires a team of 4-6 professionals working 8-10 hours, involving heavy lifting, complex tools, and repeated adjustments. In contrast, TOPOLO’s rapid assembly process overcomes the time-consuming and labor-intensive challenges of traditional equipment installation. The innovative “two people + two hours = one box” assembly concept significantly reduces labor input and sets a new benchmark for assembly efficiency in the cold chain industry.
Are you struggling with recurring issues with refrigerated box?
- Refrigeration unit vibration → cracked front panel?
- Frequent opening and closing/collision → door frame deformation or door jamming?
- Cargo impact → wall bulging (swelling)?
- Forklift loading and unloading → floor damage and collapse?
- Weak connections?
- Short service life?
01. The perfect combination of strength and thermal insulation solves these problems
Weather-resistant outer skin
- UV-resistant FRP/GRP sheets are used for the exterior skin of refrigerated boxes. They are resistant to sunlight, marine weather, rain, and snow. They offer a service life of over ten years and retain their vibrant color. TOPOLO has developed a variety of FRP sheets (thermoplastic and thermoset) for insulation panels to achieve a balance between performance and cost.
High-quality thermal insulation core material
- The insulation core material is preferably extruded polystyrene (XPS) or polyurethane (PU) or polyester foam. These foams have extremely low thermal conductivity and excellent thermal insulation performance, which ensures the high efficiency of the refrigeration unit.
High-strength embedded “skeleton”
- The interior of the refrigerated box panel has been processed and pre-embedded with “skeletons” made of various lightweight materials. These “skeletons” are distributed at the edges, corners and other stress-prone areas of the panel, enhancing the panel’s resistance to damage. Even under frequent loading and unloading, stacked transportation or extreme road conditions, the panel can be prevented from denting or breaking due to external forces.
