Modular Refrigerated Box
Flexible configuration to meet scenario applications
With the triple breakthrough of new technology, new materials and new design, TOPOLO modular refrigerated box has not only achieved a qualitative leap in refrigeration performance, but also brought multi-dimensional innovation and value to the cold chain industry through its core advantages of reducing costs and increasing efficiency. Refrigerated boxes can be customized based on transport volume and cargo type, eliminating the space and capacity issues of traditional refrigerated bodies. The same box can be configured to switch temperature zones to meet the transport needs of a wide range of products, from ice cream (-20°C) to flowers (5-10°C) to vaccines (2-8°C).
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?
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.
