Benefits of Refrigerated Trailer

Maintaining Food Freshness

One of the most important aspects of any food service operation is maintaining food safety. At festivals, where food is often prepared and served outdoors, keeping perishables at the correct temperature is vital to prevent food going off and causing potential illnesses. Refrigerated trailers provide a reliable way to store food at safe temperatures, ensuring all ingredients remain fresh from preparation to serving.

Highly Versatile

Refrigerated trailers are highly versatile and offer various configurations to suit different needs. They can be easily moved around festival grounds, allowing vendors to place them in optimal locations, ensuring convenient access to cold storage.

Increased Efficiency

Refrigerated trailers significantly increase the efficiency of food service operations by offering the ability to store large quantities of perishable items close to the serving location. This reduces the need for frequent restocking trips, allowing vendors to focus more on serving customers.

Common Uses for Refrigerated Trailers

Food and Beverages

The most widespread use of refrigerated trailers is for the transportation and storage of food and beverages. Fresh produce, dairy, frozen meats, and seafood all require consistent temperatures to maintain product freshness and prevent spoilage, and these units provide a reliable way to preserve these conditions. Whether your business is moving items from farms to grocery stores or transporting beverages to retail outlets, reefer trailers help businesses comply with strict food safety regulations and deliver the best products to their customers. They also enable companies to expand their delivery range while minimizing waste and maintaining product quality.

Pharmaceuticals

The pharmaceutical and biotech industries depend on strict temperature control for many drugs and vaccines. Refrigerated trailers are used to store and transport sensitive pharmaceuticals that must be kept within a precise temperature range to remain effective. These containers ensure these strict conditions are maintained without any fluctuations. For products from vaccines to insulin, deviations in temperature could compromise product efficacy. Reefer trailers provide a mobile solution that helps pharmaceutical companies meet compliance needs and deliver the medications people need.

High-Value Items

Beyond perishable goods, refrigerated trailers are also used to store and transport high-value items that require controlled environments. This can include fine art, electronics, or luxury products sensitive to temperature and humidity fluctuations. These trailers provide reliable cooling, as well as an added layer of security and protection during transit or temporary storage. Companies looking to protect expensive or delicate cargo often turn to refrigerated trailers for peace of mind.

Versatility

Refrigerated trailers are incredibly versatile and can be used in a variety of settings. From storing food and beverages at an outdoor event to transporting pharmaceuticals over long distances, these trailers adapt to different industries and applications. They can be placed at construction sites, used by florists for floral storage, or deployed during emergencies to support relief operations. Their broad functionality makes them a valuable resource for businesses of all sizes.

Working Of Refrigerated Trailer

Trailer Refrigeration Unit

The reefer refrigeration unit consists of three main components:

Compressor: It compresses the refrigerant gas, raising its pressure.

Condenser: Converts the refrigerant gas into a liquid by cooling it.

Evaporator: Absorbs heat from inside the trailer, reducing the temperature.

This closed-loop system keeps the air circulating, ensuring an even and consistent temperature inside the trailer.

Insulated Design

Reefer trailers are built with walls, floors, and ceilings made of metal or fiberglass to help insulate the trailer and prevent external heat or cold from affecting the cargo. This insulation plays a key role in maintaining efficiency and reducing energy consumption.

Reefer Fuel

The trailer refrigeration unit runs on a separate power source which is usually diesel fuel, commonly referred to as ‘reefer fuel ‘. It is a special type of ultra-low sulfur diesel (ULSD) used specifically for powering reefer units, ensuring the cargo stays at the right temperature during transit.

Transportation

Whether it is air freight, express delivery, or sea freight, we can arrange shipments according to the time required by customers. We help customers inquire about the best rates and arrange the delivery of your goods in the most economical way. This allows you to control the schedule of the entire project to meet seasonal cargo demand.

FAQ

Q: What is a reefer trailer?

A: Refrigerated trailers, also known as reefer trailers, are heavily-insulated and tightly secured to maintain a consistent, climate-controlled temperature for cargo. Reefer units have a trailer refrigeration unity (tfu) on the trailer's front or “nose” portion, ensuring refrigerated temperatures are maintained throughout the transportation process.

Q: How cold can a reefer trailer get?

A: Though some cargo types are less sensitive to temperature changes, some commodities, like meat and ice cream, require constant refrigeration during transit to maintain quality. As such, you May have an interest in the answer to, “how cold can a reefer trailer get?” these goods are susceptible to too-warm or too-cold temperature changes, so keeping the required 32-36 degrees fahrenheit for transporting these goods must be a top priority. So it’s less of a question of how cold can a reefer get and more about what temperature you can use a reefer trailer to maintain, considering its cargo.

Q: What is the life expectancy of a refrigerated trailer?

A: A common rule of thumb is a reefer trailer should last for an average of 40,000 hours of use which equates to about 8 years on the open road. These values are based on an average of 4,000 to 5,000 hours of use per year. Keeping your hours under 4,000 annually will then extend the lifespan of your trailer considerably.

Q: What to know about reefer trailers?

A: Refrigerated trailers are similar to standard 48' or 53' dry van trailers, but there are a few important differences: The walls, ceiling and floors are made of metal or fiberglass, never wood. This not only improves insulation, but it prevents the floors and walls from absorbing odors from product.

Q: How long can a refrigerated trailer run?

A: Reefer Trailers typically can run for two days without a refuel if opened only once or twice a day. Three days if you go a weekend without opening the trailer if fueled on Friday. If you have staff leaving the door open regularly expect to need fuel daily.
