As summer temperatures continue to rise each year, motor carriers face the challenge of reducing energy consumption while ensuring that perishable goods remain at the required temperatures for safe transport. Efficient energy use is crucial in maintaining both product quality and cost-effectiveness. Here are some strategies to optimize energy efficiency in the transport of temperature-sensitive goods, based on insights from Sid Gnewikow, product manager for small trucks at Thermo King Americas. While these suggestions focus on refrigerated straight trucks, they are equally applicable to refrigerated trailers.

Recool Your Refrigerated Trailer or Cargo Box
One of the most effective ways to enhance energy efficiency is by precooling the trailer or cargo box before loading it with perishable items. Loading products at their optimal temperatures means the refrigeration unit isn’t overburdened by having to cool them down during transport. This practice not only conserves energy but also helps maintain the quality of goods.
2. Minimize Energy Loss During Deliveries
During deliveries, it’s important to minimize energy waste. Installing door switches to shut off the Transport Refrigeration Unit (TRU) when the doors are open can prevent unnecessary energy consumption. Additionally, air curtains can be used to retain cold air and prevent warm ambient air from entering the cargo space when the doors are open. This helps maintain the required temperature and reduces the workload on the refrigeration unit.
3. Invest in Quality Insulation
Adequate insulation is crucial for maintaining consistent temperatures inside the cargo space. Using sufficient insulation or increasing its thickness can significantly reduce the electrical load required for cooling. Well-insulated trailers help preserve the desired temperature with less energy, which is beneficial for both the environment and the bottom line.
4. Ensure Regular Maintenance of Vehicles
Regular maintenance of refrigerated trailers and trucks is vital for energy efficiency. This includes ensuring that door seals are intact, using devices like “kazoos” on drain ports to prevent ambient air from entering, and addressing any damage to the vehicle, such as ripped skin panels, that could affect
5. Choose the Right Door Type
Choosing the correct type of door can also impact energy consumption. Sid Gnewikow suggests using swing doors instead of roll-up doors on cargo boxes. Swing doors typically provide a better seal and reduce the amount of time the interior is exposed to external temperatures, thereby conserving energy and maintaining the required calm environment.
