1. Basic Overview

A refrigerated semi-trailer is a specialized transport vehicle designed for temperature-controlled cargo transportation, ideal for perishable goods (e.g., fresh produce, dairy products, frozen food, pharmaceuticals). It integrates a high-performance refrigeration unit, insulated cargo compartment, and robust chassis structure to maintain stable temperatures during long-haul transportation.

3. Detailed Performance Advantages

Precision Temperature ControlThe intelligent refrigeration system supports multi-zone temperature control (optional dual-temperature zone design), allowing simultaneous transportation of frozen and fresh goods. The built-in temperature recorder can store data for 12 months, meeting the traceability requirements of food and pharmaceutical logistics.

Energy Efficiency & Environmental ProtectionThe latest generation of refrigeration units adopts variable frequency technology, reducing fuel consumption by 15%–20% compared to traditional models. It complies with Euro V/Euro VI emission standards, suitable for transportation in countries with strict environmental regulations.

Durability & SafetyThe reinforced chassis and anti-corrosion coating (epoxy zinc-rich primer + polyurethane topcoat) ensure a service life of 10–15 years. The EBS braking system shortens the braking distance by 20%, and the emergency temperature alarm function alerts the driver in real time if the compartment temperature exceeds the set range.

Customization Options

Pharmaceutical-grade modification: Equipped with GSP-certified temperature monitoring and alarm systems, meeting the transportation requirements of vaccines and biological products.

Heavy-duty modification: Reinforced floor and chassis for transporting large batches of frozen seafood or meat.

Lightweight modification: Use of aluminum alloy compartment and chassis to increase payload by 3–5 tons.

4. Application Scenarios
