Differences between Class C and Class F Refrigerated Trucks

[BradyFitz]

The differences between Class C and Class F refrigerated trucks are as follows: 1. Temperature: Class C refers to refrigerated trucks where the average internal temperature is generally between 12°C and -20°C when the ambient temperature is 30°C. They are typically used for transporting vegetables and fruits, which require relatively precise temperature control, thus demanding considerable experience and skill from the operators. Class F refers to refrigerated trucks where the average internal temperature is generally below or equal to -20°C when the ambient temperature is 30°C. They are commonly used for transporting frozen meat, seafood, frozen foods, etc. These goods generally do not require strict temperature control as long as the temperature remains below -18°C.

I usually drive refrigerated trucks, and the biggest difference between Class C and Class F is the temperature control range. Class C trucks are suitable for medium-temperature transportation between -10°C to 0°C, such as transporting vegetables, fruits, or fresh milk. The temperature fluctuation in these compartments is small, and the requirements for cargo preservation are not as high. Class F trucks, on the other hand, must maintain temperatures below -18°C, specifically designed for frozen goods like meat and ice cream that are prone to thawing. They have more powerful refrigeration units and thicker compartment walls to ensure ultra-low temperature stability. On long-distance trips, Class F trucks consume more fuel because they require continuous and strong refrigeration, especially during high summer temperatures, which puts extra strain on the equipment. In terms of maintenance, Class C trucks have cheaper parts, whereas a compressor failure in a Class F truck can be a major headache. Choosing between the two depends on the cargo being transported. For short urban trips, Class C is often used—it’s more cost-effective and hassle-free. For long-distance frozen goods, Class F is the reliable choice; otherwise, the risk of cargo spoilage mid-journey could lead to greater losses. In short, after over a decade in this industry, the temperature difference is the key factor. Don’t mix up the classes—it’ll cause delays and cost you money.

As the owner of a small freight company, we focus on the cost-effectiveness of Class C and Class F refrigerated trucks when purchasing. Class C refrigerated trucks have low maintenance costs, making them suitable for transporting chilled foods like yogurt and fruits, maintaining temperatures around -10°C. Their cabin equipment is relatively simple, fuel-efficient, and the purchase price is budget-friendly. On the other hand, Class F refrigerated trucks are designed for deep-freeze storage below -18°C, specifically for frozen meats and seafood. They feature a more robust structure and stronger refrigeration systems, naturally requiring higher initial investment and operational costs. In daily scheduling, Class C trucks are hassle-free and cost-effective for short-distance deliveries, offering better profit margins. However, for frozen orders, Class F trucks are a must to prevent product spoilage and returns. Seasonal factors also play a role—Class F trucks show less advantage in winter, but in summer heatwaves, they ensure stable temperatures. The experience shows that Class C trucks have broader versatility, while Class F trucks excel in specialized tasks. Choosing the right type enhances fleet efficiency and avoids complaints. Overall, selecting the most suitable category based on business volume improves overall profitability.

Having repaired many refrigerated trucks, the main differences between Class C and Class F lie in refrigeration performance and working temperature. Class C handles temperatures from -10°C to 0°C, with thinner walls being acceptable, making it suitable for transporting fruits and vegetables, and maintenance is simpler. Class F must maintain temperatures below -18°C, requiring more powerful compressors and thicker inner walls to ensure stable low temperatures. Key components in Class F are more prone to wear, leading to higher costs. Choose the type based on the cargo.
