A reefer trailer is a heavy-duty semi-trailer designed for long-haul, bulk cold-chain transport. It is equipped with an independent diesel refrigeration unit and features a fully sealed body with a thick polyurethane foam insulation layer, internal air circulation ducts, and non-slip, ventilated aluminum flooring. Its temperature control capabilities span ranges suitable for fresh produce, chilled goods, deep-frozen products, and pharmaceuticals. Mounted on a multi-axle heavy-duty chassis, it can be hitched to a tractor unit for long-distance transport of perishables—such as fruits, vegetables, meat, seafood, and frozen goods—or parked independently at facilities or markets, where it can connect to the mains power grid to serve as a large-scale temporary cold storage unit.

Features of the Reefer Trailer: 

Independent diesel refrigeration unit, unrestricted power supply; Equipped with its own diesel fuel tank, it does not rely on a tractor or external power source, allowing for uninterrupted temperature control in high-speed and remote storage yards; It also supports external 220/380V AC mains power for static insulation, maintaining coldness even after the engine is shut down upon arrival at the station.

Wide-Range, Precise Temperature Control

Adjustable temperature range of +25°C to -25°C, customizable for various needs: 0–10°C for fresh produce, -5–0°C for fresh meat, below -18°C for frozen seafood, and 2–8°C for pharmaceuticals.

High-Density, Thermal-Break Insulated Body

Walls, roof, and floor are formed via integrated foaming with thermal-break joints. Doors feature multi-layer magnetic seals to minimize cold air loss, ensuring minimal temperature fluctuation and reduced cargo damage during long-haul transport.

Heavy-Duty Structure for Durability

Built on a heavy-duty tri-axle semi-trailer chassis with high load capacity. The floor features aluminum alloy ventilation channels that are strong, easy to wash, and promote uniform airflow to eliminate localized temperature variations.

Compliant Cold Chain Traceability

Standard features include a temperature/humidity logger and audible/visual over-temperature alarms; optional remote monitoring meets strict regulatory standards for food exports and pharmaceutical/vaccine cold chain management.

Corrosion-Resistant and Rugged

Exterior clad in waterproof fiberglass or aluminum alloy panels; chassis features electrophoretic anti-rust coating and reinforced corner guards. Built to withstand rain, snow, salt spray, and rough road conditions for a long service life.

Flexible Customization Options

Options include dual-temperature partitions (refrigeration and freezing zones), side-access doors, hydraulic tail-lifts, cargo securing straps, multi-level shelving, and waterproof LED interior lighting.

Dual-Use for Transport and Storage

Can serve as a stationary cold storage unit after delivery, eliminating the need for permanent civil construction. It offers a cost-effective solution for temporary capacity expansion at wholesale markets, farms, and processing plants.
