Sturdy structure:

His production cost will be much higher than the dry van, whether it’s a small or heavy-duty trailer. So, we focus more on the structure and the accessories’ service life. Thus, the shell is very important.

Refrigerated trailers use durable, high-strength fiberglass. It is waterproof, scratch-, dent-, rust-, and corrosion-resistant. It can withstand harsh environments while keeping the trailer’s appearance neat. Our small freezer trailer has the same structure as the large refrigerated one. We will cut no corners.

Strong insulation performance:

We use XPS or PU foam. The panel thickness is 30-120 mm. You can adjust the density and thickness as needed. XPS foam is non-absorbent. Its insulation is second only to PU foam, and it has a higher density. You can keep excellent insulation in -20℃ or 50℃.

Application of Small Reefer trailer

Insulated trailer: Used for transporting goods that are sensitive to high temperatures.
Refrigerated small trailers: Our trailers are for short-distance purposes. These include produce and meat delivery, catering, florists, and convenience store transport.
Freezer small trailers: Frozen trailers can transport goods that must stay at -18℃. This includes ice cream, meat, flowers, and medications. They are suitable for long-distance transport.
