Dongfeng Tianjin Refrigerated Truck – 330 HP 6.8-Meter Cold Chain Carrier

I. Product Introduction

The Dongfeng Tianjin Refrigerated Truck is a high-performance cold chain vehicle designed for long-haul transport of fresh produce, frozen goods, pharmaceuticals, and other temperature-sensitive cargo. Powered by a Cummins 330 HP engine (D7.0NS6B330) and built on the intelligent Dongfeng Tianjin D560 PLUS chassis, this 6.8-meter refrigerated truck delivers exceptional reliability, fuel efficiency, and thermal stability. With a gross vehicle weight of 18,000 kg and a 5,000 mm wheelbase, it is the ideal choice for logistics companies, food distributors, and pharmaceutical supply chains requiring consistent temperature control.

II. Core Parameters

III. Exterior Dimensions, Body Size, Material & Design Philosophy

• Cargo Box Dimensions (L×W×H): Approximately 6,800 mm × 2,450 mm × 2,400 mm (volume ~32–35 m³, depending on wall thickness).

• Material: The box uses a steel-wood composite structure with thermal break technology. Inner and outer skins are high-quality fiberglass (non-light-absorbing, high insulation, hard, and oxidation-resistant). The middle layer is filled with 80 mm thick XPS extruded polystyrene foam.

• Flooring: Plastic-steel checkered plate for durability and slip resistance.

• Side Skirt: 150 mm internal side skirt to prevent cargo shifting and improve air circulation.

• Sealing: Labyrinth-type rubber door seals and bright stainless steel door frames ensure airtight integrity.

• Reinforcements: Galvanized steel tube skeleton; hot-pressed using automated gluing and pressing technology to prevent bubbling and ensure uniform adhesion.

• Design Philosophy: “Thermal efficiency + durability” – the combination of XPS insulation, thermal break bridges, and seamless panel assembly minimizes heat infiltration, keeping the cargo at stable temperatures for longer. The lightweight yet rigid structure maximizes payload.

IV. Structural Advantages – Engine, Transmission, Axles & Chassis

• Engine (Cummins 330 HP): The D7.0NS6B330 7.0L engine delivers strong low-end torque for heavy loads, excellent fuel economy, and proven reliability for long-haul refrigerated transport.

• Transmission Options: Choose between a Fast 8JSQX120TE (8-speed) for balanced performance or a Fast 10JSD120TB (10-speed) for finer gear splitting and better gradeability. Both are matched to the engine’s torque curve.

• Front Axle (4.5T) & Rear Axle (9T): The 9T rear axle with optional ratios (3.91 or 3.64) provides superior load-carrying capacity and allows optimization for highway cruising or mixed terrain.

• Chassis Frame: 220×75×7 mm frame with 8/10+8 leaf springs. The full-floating cab suspension (front/rear mechanical or optional air) dramatically reduces driver fatigue on long journeys.

• Suspension: Option for front/rear air suspension on the second configuration, further improving ride quality and cargo protection.

• Wheels & Tires: 275/80R22.5 18PR radial tires offer low rolling resistance and high load capacity.

• Fuel Tank: 600 L aluminum tank provides extended range and corrosion resistance.

V. Product Features & Chengli Group Manufacturer Advantages

Product Features

• High-Efficiency Insulation: The 80 mm XPS core combined with thermal break technology and automated hot-pressing ensures uniform insulation, preventing hot spots and reducing temperature fluctuations.

• Durable Construction: Fiberglass inner/outer skins resist corrosion, impact, and UV damage, while the galvanized steel skeleton adds structural integrity.

• User-Friendly Interior: LED lighting, stainless steel hinges and lock sets, and a sloped front drainage hole for easy cleaning.

• Smart Cab Features: D560 PLUS intelligent high-roof double sleeper cab with aluminum air tanks, intelligent cockpit, and optional rear-differential package (second config).

• Refrigeration Ready: Standard Chengli 1550 cooling unit (or upgrade to major brands) ensures reliable temperature control from -18°C to +20°C.

• Versatile Applications: Ideal for frozen food, dairy, fresh produce, meat, seafood, and pharmaceutical logistics.
