What is the difference between Class F and Class C refrigerated trucks?
2 Answers
To ensure the transportation of frozen, refrigerated, insulated, and constant-temperature goods, the transportation department has classified refrigerated trucks into eight grades. Based on the average temperature range maintained inside the refrigerated truck compartment, there are the following six standards: 1. Refrigerated trucks with an average internal compartment temperature between 12°C and 0°C are classified as Class A. Therefore, if you see a refrigerated truck labeled as Class A on the road, you can estimate its internal temperature; 2. Refrigerated trucks with an average internal compartment temperature between 12°C and -10°C are classified as Class B; 3. Refrigerated trucks with an average internal compartment temperature between 12°C and -20°C are classified as Class C; 4. Refrigerated trucks with an average internal compartment temperature of 0°C or below are classified as Class D; 5. Refrigerated trucks with an average internal compartment temperature of -10°C or below are classified as Class E; 6. Refrigerated trucks with an average internal compartment temperature of -20°C or below are classified as Class F;
I drive a refrigerated truck and have been doing so for ten years. The difference between Class F and Class C is quite obvious. Class C trucks maintain temperatures between zero and eight degrees Celsius, suitable for fresh vegetables, dairy products, or medical supplies. Class F can drop below minus twenty degrees, specifically designed for frozen meat and ice cream. I remember once using a Class C truck to transport frozen seafood by mistake, and the temperature didn't meet the requirements, causing the cargo to melt and resulting in a financial loss. Choosing the right truck depends on the type of cargo: Class C is simpler to operate, consumes less fuel, and has cheaper maintenance; Class F requires a more powerful refrigeration system, such as a dual-compressor setup, and has thicker insulation. Although it costs more in terms of fuel and maintenance, it's safe and reliable for long-distance transport of frozen goods. Over the long term, Class F trucks are more prone to issues in the summer and require frequent compressor checks, but the benefit is ensuring quality and avoiding waste due to broken cold chains.
