Reefer fuel tank capacity and usage

Reefer fuel tanks are crucial for transporting and preserving goods that need to be kept at a specific temperature. They are used in refrigerated trailers, which have their own motor and reefer fuel tank to maintain the cargo's temperature even when the truck is turned off. Reefer fuel is a type of diesel formulated to work in colder temperatures with higher stability, ensuring the safe operation of the refrigeration unit.

The reefer fuel tank capacity varies depending on the manufacturer and model of the trailer. Common capacities range from 50 to 100 gallons. For example, Carrier Transicold and Thermo King typically offer 50-gallon reefer fuel tanks. The size of the tank impacts the usage between fill-ups, with larger tanks providing more flexibility.

The duration of a tank of reefer fuel depends on various factors, including the trailer's age, load size, and the required temperature. Older trailers tend to consume more fuel, with usage ranging from 1 to 3 gallons of reefer fuel per hour. In contrast, modern reefer trailers are more fuel-efficient, with newer units consuming between 0.4 and 1.1 gallons of fuel per hour. Therefore, a typical 50-gallon reefer fuel tank can last between 25 and 50 hours, or approximately two to four days, depending on usage.

To optimise reefer fuel usage, it is essential to understand the cargo's required temperature and the trailer's settings. Loads requiring absolute temperature control should be run on continuous mode, while those with variable temperature controls can utilise the reefer's auto settings. Proper management of reefer fuel usage is critical for controlling costs and ensuring timely deliveries.

The cost of a reefer fuel tank can range from $500 to $3,000, depending on its size and capacity. Small tanks (less than 100 gallons) typically cost $500 to $1,000, while medium-sized tanks (100-200 gallons) range from $1,000 to $2,000. Large tanks with a capacity of more than 200 gallons generally cost between $2,000 and $3,000.

The cost of reefer fuel tanks

Reefer fuel tanks are crucial components in the transportation and preservation of perishable goods. These specialised vehicles ensure that temperature-sensitive goods, such as chemicals, medications, and food supplies, can be safely transported over long distances. Reefer trucks have two fuel tanks: one for powering the refrigerator and the other for the engine.

The price of reefer fuel also varies depending on the region, season, state of the fuel market, fuel type, and supplier. As of October 2023, the average cost of reefer fuel in the United States was $2.18 to $2.81 per gallon. Reefer fuel is generally less expensive than diesel fuel due to its off-road use classification and lower taxes. However, it is important to note that using reefer fuel for on-road vehicle operations is illegal and can result in significant fines.

To manage costs effectively, organisations must consider long-term expenses such as fuel economy, maintenance, and operating costs. Additionally, understanding daily consumption patterns can help determine usage across extended periods and calculate the average time between refuelling. A typical reefer fuel tank has a capacity of 50 gallons, and depending on usage, it can last between 25 to 50 hours, or approximately two to four days.

Differences between reefer fuel and diesel

The duration of a tank of reefer fuel depends on the size of the tank, the temperature, and the rate of fuel consumption. A typical reefer fuel tank has a capacity of 50 gallons, and reefers consume between half a gallon and one gallon of fuel per hour. Therefore, a tank of reefer fuel can last anywhere from two to four days, or even up to five days if the tank is larger.

Now, let's discuss the differences between reefer fuel and diesel:

Usage

Reefer fuel, or refrigerated fuel, is used specifically for powering the refrigeration units in trucks, trailers, and shipping containers that transport perishable goods. It is essential for maintaining a controlled temperature. On the other hand, diesel is used to power vehicles, including the engines of those same trucks. So, a refrigerated truck has two separate fuel tanks: one for diesel to power the truck's engine and another for reefer fuel to power the refrigeration unit.

Legal Classification

The main difference between reefer fuel and diesel lies in their legal classification. Diesel is considered an on-road fuel, which means it can be used for vehicles driven on public roads and highways. As a result, diesel fuel is subject to higher taxes to fund transportation projects. In contrast, reefer fuel is classified as an off-road fuel and is legally prohibited from being used to power vehicles on public roads. This restriction is strictly enforced, and violating it can result in hefty fines of up to $10,000.

Chemical Composition

Despite their different uses and legal statuses, reefer fuel and diesel have similar chemical compositions. However, reefer fuel is formulated to have improved stability and oxidation resistance, especially under cold and cycling conditions. It also has a lower viscosity than standard diesel, allowing it to flow more easily at low temperatures and prevent gelling issues that can clog filters.

Cost

Due to the road taxes associated with diesel, reefer fuel offers significant cost savings for off-road vehicles. Off-road vehicles that use reefer fuel can save thousands of dollars annually compared to using diesel. This makes reefer fuel a more cost-effective option for vehicles that operate on private property, such as farm or construction equipment.

Appearance

To distinguish reefer fuel from diesel and prevent misuse, reefer fuel is dyed red. This dye makes it easy for authorities to detect when reefer fuel is used illegally on public roads, as the dye can be identified with a black light.

Where to buy reefer fuel

Reefer fuel is used to power the refrigeration systems of tractor-trailers, which are used to transport perishable goods. Reefer fuel is a type of diesel that is intended solely for off-road use. It is usually stored in a separate tank from the fuel that powers the engine of the vehicle.

When it comes to purchasing reefer fuel, there are a few options available:

Gas Stations

Most gas stations that service diesel trucks also provide reefer fuel. This is a convenient option for those who are on the road and need to refuel their vehicles. When at the pump, drivers typically fill their main tanks with diesel first and then move on to filling their reefer fuel tank. It is important to note that reefer fuel is not to be used to power the vehicle's engine, as it is strictly for off-road use and using it for on-road operations can result in hefty fines.

All-Terrain Vehicle Service and Sales Companies

Reefer fuel is also available at all-terrain vehicle service and sales companies. This is because reefer fuel is often used in off-road vehicles, such as ATVs. This option may be useful in a pinch if you are unable to access a gas station that provides reefer fuel.

Reefer Fuel Delivery Services

There are specialised companies, such as Foster Fuels, that offer reefer fuel delivery services for refrigerated trailers. These services can be useful for businesses that rely on the timely delivery and storage of perishable goods. They offer guaranteed fast response times to meet the demanding schedules associated with fueling refrigerated trailers.

Regular Diesel

In some cases, you may be able to use regular diesel in your reefer fuel tank. However, it is important to note that regular diesel is subject to road taxes, so you will have to pay higher taxes initially. You can then file for a refund using Form 4136 from the IRS to recoup the taxes paid. Regular diesel can also be distinguished by its red dye, which is added to prevent its misuse in on-road vehicles.

How to fill a reefer fuel tank

The duration of a tank of reefer fuel depends on several factors, including the age and model of the reefer unit, the outside temperature, and the size of the load. Generally, a reefer fuel tank with a capacity of 50 gallons needs to be refuelled every two to four days.

Now, here is a step-by-step guide on how to fill a reefer fuel tank:

Firstly, identify the location of the reefer tank. The reefer fuel tank is typically found below the trailer, and it is cylindrical in shape. Once located, pull forward until the reefer tank is aligned with the pump's hose or nozzle.

Before initiating the refuelling process, it is crucial to turn off the refrigeration unit temporarily. This step ensures the safety of the procedure. After powering down the reefer unit, you can begin filling the tank with the appropriate fuel type. Reefer fuel is specifically designed for these refrigeration units and is usually available at gas stations that service diesel trucks.

During the refuelling process, it is important to keep safety measures in mind. Always use the right fuel type, as using regular diesel in a reefer could lead to engine damage or even a fire due to the differences in energy density and flashpoint between reefer fuel and regular diesel. Reefer fuel is dyed red to distinguish it from regular diesel and prevent accidental misuse.

Once the tank is filled, don't forget to restart the reefer unit. This step is crucial to ensure the refrigeration system is operational and maintaining the desired temperature for your cargo.

Additionally, it is recommended to maintain at least a quarter tank of reefer fuel at all times. This practice helps to avoid the risk of the refrigeration unit shutting down, which could lead to the spoilage of temperature-sensitive goods. Regular maintenance of the refrigeration unit is also advised to optimise fuel efficiency and minimise costs.
