What is the difference between Class F and Class C refrigerated trucks?

[OKennedy]

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.

In fleet management, I've found the distinction between Class F and Class C refrigerated trucks to be crucial. Class C maintains warmer temperatures, between 0 to 10 degrees Celsius, suitable for perishables like fruits and flowers; whereas Class F is designed for deep freezing, capable of reaching as low as -20 degrees, ideal for meat and seafood. The differences impact costs significantly: new Class F trucks cost 20-30% more due to their more powerful refrigeration units and higher insulation requirements. Maintenance is also more frequent for Class F, such as monthly coil inspections to prevent freezing. Energy consumption differs too: Class F trucks consume 15% more fuel in hot weather, affecting overall operational costs. Choosing the wrong type not only damages goods but also violates cold chain regulations—like when our fleet once misused a truck, leading to customer complaints. My advice is to select based on logistics needs: opt for Class F if regularly transporting frozen goods; otherwise, Class C is more cost-effective and efficient.

I learned about refrigerated trucks from a friend who repairs vehicles. The difference between Class C and Class F lies in the temperature range. Class C maintains temperatures within 10 degrees above zero, suitable for refrigerating items like vegetables; Class F can drop to minus 20 degrees, used for freezing items like ice cream. The core technologies differ: Class F trucks require more powerful refrigeration systems and double-layer insulation to prevent frost, while Class C can operate with standard equipment. Choosing the wrong type in practical use can easily lead to issues, with Class F consuming more fuel in hot summers.
