The core configuration of a refrigerated truck is divided into five parts: chassis, refrigeration unit, insulated box body, special functions, and electronic control/monitoring.
| independent unit | Equipped with its own engine, capable of cooling while parked, temperature range: -18℃ to +25℃, suitable for pharmaceuticals / deep freezing. |
| non-independent unit | Driven by the main engine, low cost, ideal for short-distance fresh food transportation (-5℃ to +15℃). |
| refrigeration unit brand | Thermo King, Carrier |
| van body / box body | Heat insulation and cold retention |
| box body structure | Internal and external fiberglass reinforced plastic (FRP) with middle insulation layer (80–100mm thick, commonly polyurethane or polystyrene). |
| box body floor | Aluminum checkered plate / stainless steel / ventilation trough, equipped with floor drain. |
| box body door | Rear double doors / single side door; fitted with sealing strips and anti-collision rubber strips. |
| optional | Ventilation troughs, meat hook rails, pharmaceutical-grade internal frames, side door thermal insulation curtains. |
| temperature monitoring | Dual-temperature recorder with printing function (mandatory for pharmaceuticals / vaccines). |
| temperature zone | Single-temperature / dual-temperature / multi-temperature (for goods requiring different temperature zones). |
| ventilation / drainage | Floor ventilation troughs, ceiling ventilators, floor drains. |
| reinforcement | Meat hooks, thermal insulation partitions, lashing and fixing devices. |
| new energy | Electric refrigeration, fast charging, 220V external power supply. |
