Refrigerator Truck(commonly abbreviated as Refrigerated truck) is a special commercial motor vehicle fitted with an independent mechanical refrigeration unit, insulated cargo compartment and temperature control system, engineered to maintain a preset constant low-temperature environment inside the enclosed cargo body throughout transportation, regardless of ambient external temperature fluctuations.

Detailed Extended Explanation

Body Structure Description Its cargo box is constructed with multi-layer thermal insulation sandwich panels made of polyurethane foam sandwiched between inner and outer fiberglass or steel skins to minimize heat infiltration and prevent cold loss. All compartment door seams and gaps are equipped with rubber sealing strips for airtightness.

Refrigeration Unit Function The mounted refrigeration compressor system powered by either the vehicle’s main engine or a standalone auxiliary diesel engine circulates refrigerant to absorb internal heat, enabling adjustable temperature ranging from deep-freeze level (-25℃ ~ -20℃) for frozen food, medium cold storage (0℃ ~ 5℃) for fresh fruits, vegetables, dairy and chilled meat, to controlled ambient temperature (10℃~25℃) for pharmaceutical, biological reagent and special chemical cargo.

Application & Classification Definition Classified by load capacity into light-duty, medium-duty and heavy-duty refrigerated trucks; widely applied in cold-chain logistics for frozen seafood, fresh produce, vaccine transportation, frozen meat and quick-frozen food distribution across land haulage.

Advantages:

1. Precise temperature control. Supports adjustable temperature from -25℃ to +25℃, keeps goods fresh and intact during transportation.

2. Superior heat insulation. High-density insulated panels and full sealing reduce cold loss and save fuel cost.

3. Wide application range. Suitable for frozen food, fresh produce, dairy, vaccines and temperature-sensitive cargo.

4. Stable refrigeration performance. Reliable refrigeration unit ensures continuous cooling for long-distance transport.

5. Low operation cost. Energy-saving design and durable body structure reduce maintenance expenses.

6. Customizable design. Multiple sizes and optional configurations meet different logistics needs.
