What do Class B, C, and F refrigerated trucks mean?

[VonLily]

Class B, C, and F refrigerated trucks represent the refrigeration grades of refrigerated vehicles. To ensure the transportation of frozen, refrigerated, insulated, and constant-temperature goods, the transportation department has classified refrigerated trucks into eight grades, marked with letters A to F. Below is the relevant introduction: Class B compartment: Refrigerated trucks with an average internal compartment temperature between 12°C and -10°C. Class C compartment: Refrigerated trucks with an average internal compartment temperature between 12°C and -20°C. Class D compartment: Refrigerated trucks with an average internal compartment temperature of 0°C or below. Class F compartment: Refrigerated trucks with an average internal compartment temperature of -10°C or below.

The Class B, Class C, and Class F of refrigerated trucks refer to different temperature level classifications in cold chain transportation. Having driven refrigerated trucks for over a decade, I have deep personal experience with this. Class B refers to freezer trucks, used for transporting items like ice cream or frozen meat, where the temperature must be maintained at around -18°C. If the temperature fluctuates significantly, the goods can thaw and spoil. Class C is for refrigerated trucks, suitable for transporting vegetables, fruits, or dairy products, with the optimal temperature range between 0°C and 4°C. If the temperature is too high, the food can rot. I don't use Class F very often, but it seems to be the type of multi-temperature zone refrigerated truck that can adjust temperatures in different sections, such as having one area for freezing and another for refrigeration, which is suitable for complex cargo. Choosing the right class is crucial; otherwise, you could lose money on a single shipment. I recommend checking if the onboard thermometer is accurate and keeping the cargo compartment clean. During long summer trips, it's best to start cooling in advance to avoid regretting spoiled goods later.

In our logistics company's refrigerated truck management, the core of B, C, F classification lies in distinguishing application scenarios. Class B represents deep-freezing level with temperature set at -18°C, specifically designed for frozen foods like seafood, requiring high-power compressors. Class C is standard refrigeration level with temperature range of 0-7°C, ideal for transporting milk or fresh meat/poultry. Class F is less common, possibly referring to multi-functional or constant temperature control, suitable for high-sensitivity cargo like pharmaceutical transport. Misuse can cause cargo spoilage rates to skyrocket, increasing costs. Modern fleets must also consider energy efficiency by selecting low-consumption models to reduce expenses. During operation, ensure even cargo stacking for proper cold air circulation, and conduct regular maintenance of refrigeration systems to prolong equipment lifespan.

As a small shop owner who frequently restocks, refrigerated trucks are categorized into Class B, C, and F, which indicate different freshness standards. Class B is for freezing, suitable for chilled fish and frozen products; Class C is for refrigeration, ideal for transporting fruits or cold beverages; Class F is said to allow multiple temperature adjustments, though I haven’t used it in practice. Choosing the wrong truck can spoil the food—for example, putting vegetables in a freezing truck will cause them to freeze and ruin their texture. Therefore, I always ask the supplier about the truck type in advance, and pairing it with a smart temperature monitoring app is even better. Safety should not be overlooked, as temperature fluctuations can easily breed bacteria and affect health. When selecting a truck, consider the distance—short trips can save fuel, while long-term planning saves hassle and money.
