The cold chain logistics industry is shifting focus from rapid expansion to high-quality development, bringing higher standards for refrigerated vehicles — superior heat preservation, solid structure and intelligent control are all essential.
SUNHUNK refrigerated semi-trailers have been fully upgraded with refined craftsmanship and outstanding performance, standing out as star products in the market. Let’s explore its core advantages in detail.
This three-axle refrigerated semi-trailer has an overall length of 13.6 meters with capacity for 33 pallets, ideal for long-distance haulage. Matched with 4×2 tractors, it delivers flexible mobility and meets diverse cold chain transport demands.

Adopting European imported panel production equipment and open foaming technology, it ensures even and full density of insulation layers without hollow gaps inside compartment panels.
Both inner and outer skins are made of pre-coated galvanized steel sheet, featuring smooth surface and strong corrosion resistance.
The interior floor adopts high-strength aluminum profiles with great load-bearing capacity for easy pallet loading and unloading.
Rear door frames, locking rods and latches are made of 304 stainless steel, while hinges are thickened aluminum alloy for enhanced structural strength and long service life.
The main beam is built with high-strength low-temperature resistant materials. Equipped with BPW axles and air suspension, it realizes even load distribution and safer, more stable road travel.
Inner wall with PVC film coating, eco-friendly and odor-free, complying with food contact safety standards.
Flat corrugated aluminum floor with transversely pressed anti-slip lines greatly improves anti-skid performance.
300mm aluminum anti-collision plates fitted on side panels for strong impact resistance; recessed cargo fixing grooves and movable aluminum support rods in the middle firmly secure goods in place.
Three-section air guide cloth installed on the ceiling to guide cold air to the rear compartment and ensure smooth circulation of refrigeration units.

Optional Carrier Vector 1550 refrigeration unit supports both cooling and heating with temperature range from -25℃ to 25℃.
