FAQ

Q: Is the temperature control performance of this refrigerated truck body stable? Is it suitable for long-distance transport?

A: It features an integral high-pressure PU foam structure, ensuring stable thermal insulation performance with a thermal conductivity coefficient of ≤0.31 W/(m²·K). It can consistently maintain temperatures ranging from -25°C to +10°C over extended periods.

Q: Can this be customized to fit my specific truck chassis?

A: Yes, absolutely. We support compatibility with most truck and semi-trailer chassis; both dimensions and structural configurations can be fully customized.

Q: Approximately how much does it cost? What factors influence the price?

A: The price primarily depends on the dimensions, material specifications, insulation thickness, and whether a refrigeration unit is included.

Q: Can the unit be shipped as disassembled components (CKD), or must it be shipped as a complete vehicle?

A: We support both methods: export as CKD (Completely Knocked Down) kits or delivery as CBU (Completely Built-Up) units.

Q: Will the insulation material degrade or lose its effectiveness over time?

A: We utilize a high-density (40 kg/m³) integral PU foam structure with B2-grade flame retardancy. This material is highly durable and resistant to collapse or degradation during long-term use, offering a service life of up to 15 years.

Q: Does it support multi-temperature zone transport?

A: Yes, it does. We can design partition structures to create single or multiple temperature zones, allowing for the simultaneous transport of different types of cargo with varying temperature requirements.

Q: What is the approximate lead time for delivery?

A: Typically, the production cycle takes approximately 15 to 30 days, depending on the specific configuration requirements.

Q: This is my first time purchasing a refrigerated truck body; what should I do if I am unsure how to select the right configuration?

A: We can provide comprehensive configuration recommendations tailored to your specific needs, taking into account the type of cargo you transport, your temperature requirements, and the specifications of your truck chassis.
