4.2m Refrigerated Truck Body with Integral Ventilation Rail System

The 4.2m Refrigerated Truck Body with Integral Ventilation Rail System combines compact urban cold chain performance with one-piece aluminum rails that double as air distribution channels. With an interior volume of approximately 18.8 m³ and an interior length of 4,080 mm, this body is built for operators who need reliable temperature uniformity and a versatile rail interior for hanging, shelving, and load securing — all in one compact package.

The defining feature is the integrated ventilation rail system: one-piece extruded aluminum rails mounted flush into the side walls, with built-in air channels that guide cold air from the reefer unit along the cargo space for even temperature distribution and reduced hot spots near the walls. The same rails accept a full range of accessories — meat hanging hooks, adjustable shelving brackets, and cargo tie-down rings — allowing the interior to be reconfigured quickly between jobs. The body is built with FRP sandwich panel or polyurethane (PU) integral foam construction, delivering stable temperature retention from -25 °C to +15 °C, while the corrosion-resistant aluminum rail surface is easy to clean and suitable for food-grade cold chain operations.
