Reefer Trailers Temperature Settings Explained: Finding the Sweet Spot

Trailer temperature is a common source of frustration that is experienced in the transportation industry. It's important to understand how compartment temperatures affect the overall vehicle temperature and ensure that product arriving at receivers is in optimal condition.

While there are many variables to consider when setting the refrigerator temperature for a trailer, we've developed guidelines based on the types of products.

Let's dive deep into each of them!

1. Produce

Produce is one of the most sensitive products to temperature, and it's important to ensure that the temperature of your trailer remains at a constant level. A change in temperature can cause damage to fresh produce, which will be reflected in the quality of your finished product when it arrives at its destination. If you're transporting fresh produce such as apples or oranges, you'll want to follow these guidelines:

- The lower compartment should be set at between 34-38 degrees Fahrenheit

- The upper compartment should be set between 50-55 degrees Fahrenheit

The best temperature to store produce is 3°C (37°F).

The ideal conditions will help the produce retain its nutritional value, taste, and color. Keep in mind that these are general guidelines, as some fruits and vegetables have different requirements. For example, apples and tomatoes should be stored at room temperature rather than refrigerated.

When setting up your compartment, make sure there are vents on all sides of the trailer so that cold air can circulate properly. It's also important that you don't put any extra weight inside the box as this will increase energy consumption and decrease performance.

2. Poultry, Dairy, Meat, and Fish

Poultry, dairy, and meat products should be stored in their original packaging. If the item is wrapped in plastic, remove it before storing it. Fish should be kept on ice or at a temperature of 40°F or below.

3. Pharmaceuticals

Pharmaceuticals should be stored in their original packaging and kept at room temperature, with the exception of liquids. Some medications may need to be stored at a specific temperature, so check with your pharmacist before storing them. If you need to transfer the product from one container to another, make sure it's done under sterile conditions.

4. Florals and Plants

The best reefer temperature for transporting florals and plants is 36 degrees F. Humidity can also affect plants, so the ideal environment should have moderate to high levels of humidity.

Flowers and plants lose a lot of their moisture as soon as they are picked. Luckily, reefer trailers come equipped with special systems that can be used to control the level of humidity in the air inside them.



Wrapping Up

To achieve the best operating temperature, there are three factors involved: load size, load density, and temperature range. Understanding these three factors is key to optimizing your refrigerated trailer's performance.
