Introduction to Temperature-Controlled Transportation
Temperature-controlled transportation is a crucial aspect of various industries, including food and beverage, pharmaceuticals, and healthcare. Refrigerated trailers play a vital role in maintaining the quality and safety of perishable goods during transportation.
With the ability to control temperature ranges from 0°F to 50°F, refrigerated trailers are an essential component of fleet management. Whether you’re looking for small refrigerated trailers or larger units, there are various options available to meet your specific needs. In this section, we will explore the importance of temperature-controlled transportation and the benefits of using refrigerated trailers.

What are Refrigerated Trailers?
Refrigerated trailers (often referred to as cooler trailers or freezer trailers) are specialized vehicles designed for temperature-controlled storage and transportation. These trailers use advanced refrigeration units to maintain consistent temperature ranges, making them ideal for industries where preservation is critical.
Built with one-piece, seamless fiberglass construction, refrigerated trailers are insulated to keep the interior at precise temperatures. Whether you need to keep products cool, frozen, or somewhere in between, these trailers ensure safety and quality through every mile.
Unlike our competitors who limit their selection to a single brand or model, we offer a diverse range of high-quality trailers tailored to various refrigeration needs, showcasing our commitment to quality and innovation in design.
Benefits of Using Refrigerated Trailers
Why invest in refrigerated trailers? Here are some key benefits that stand out for businesses:
- Reduce Spoilage and Waste: Maintain temperature consistency and avoid the risk of perishable goods or sensitive materials becoming unusable.
- Temporary Refrigeration Solutions: Perfect for occasions such as events, seasonal demand increases, or emergencies. Restaurants, hospitals, and even government agencies rely on them for quick refrigeration whenever needed.
- Long-Term Efficiency: Investing in refrigerated trailers reduces operational interruptions while enabling seamless deliveries and storage.
- Safety and Reliability: Durable construction, advanced insulation, and professional-grade refrigeration units make these trailers a reliable choice for long-term use.

Types of Refrigerated Trailers
Refrigerated trailers come in a variety of types to meet specific business needs. Knowing which one suits your operation is crucial.
Small Refrigerated Trailers
These compact trailers are designed for businesses that don’t need to haul large quantities. Small refrigerated trailers maintain a precise temperature range, making them ideal for food vendors, event organizers, and small-scale distributors.
- Benefits include easy maneuverability and reduced operating costs.
- Customizable options like pallet duty floors and four-inch walls optimize performance.
Freezer Trailers
Freezer trailers are designed to keep goods frozen during transportation. If your business deals with frozen food items or pharmaceutical products, these trailers are an excellent choice. Timely delivery is crucial to ensure the availability of freezer trailers, as it guarantees that your products remain at the required temperatures during transit.
Most freezer trailers come with efficient freezing units to maintain sub-zero temperatures.
Cooler Trailers
Cooler trailers are used when products require refrigeration rather than freezing. Perfect for transporting fruits, vegetables, or beverages, these offer a reliable solution for maintaining product quality.
Trailer Specifications
Polar King Mobile refrigerated trailers feature a rugged construction with a one-piece, seamless fiberglass design. The trailers are available in three standard models: 6’x8’, 6’x12’, and 6’x16’. Each trailer features 54-inch reinforced doors, four-inch walls, and a pallet-duty floor.
The interior of the trailers is coated with an antimicrobial gel coating, ensuring a clean and hygienic environment for storing medical supplies and other perishable goods. The actual cooling of the trailer is achieved using a GOVI arktik 2000US series refrigeration unit, which provides a temperature range of 0°F to 50°F. With a focus on trailer safety and efficiency, these units are all-electric and require only 110V and 15 amps to operate.
Fleet Management and Maintenance
To get the most out of your refrigerated trailers, you’ll need to focus on effective fleet management and maintenance. Here’s how you can ensure they are always ready to operate efficiently:
- Routine Maintenance: Inspect insulation, refrigeration units, and structural components regularly to maintain peak performance.
- Safety Inspections: Trailer safety is crucial. Implement regular checks for any cracks, leaks, or system malfunctions that could compromise temperature control.
- Streamlined Fleet Management: Utilize specialized tools to track the performance and maintenance schedule of your trailers, ensuring smooth operations without unexpected failures.
Investing in proper fleet management not only ensures reliable temperature control but also reduces long-term costs and inefficiencies.
Temperature Range and Control
The most critical aspect of refrigerated trailers is their ability to maintain a precise and consistent temperature range. Different requirements call for different systems, and understanding these can help make the perfect fit for your business.
How Temperature Control Works
The actual cooling process in these trailers is achieved using refrigeration units such as evaporators and condensers. The evaporator plays a critical role by releasing cooled liquid to maintain the desired temperature. These systems regulate interior temperature by managing airflow and ensuring heat is removed efficiently.
Options for Flexibility
Depending on your needs, you can select trailers with adjustable temperature controls for freezing, refrigeration, or ambient temperature. These customizable systems are particularly useful for businesses handling diverse products. You can also have the unit set to a specific temperature upon delivery, whether as a refrigerator or freezer, providing flexibility and customization for various storage needs.
Applications Across Industries
Refrigerated trailers serve an essential role across multiple industries. Here’s how specific businesses benefit from their use:
- Food Service: Restaurants, caterers, and grocery suppliers use refrigerated trailers to ensure their food remains fresh during transportation or storage.
- Healthcare: Transporting medical supplies like vaccines and medications requires stringent temperature control, making refrigerated trailers indispensable in healthcare logistics.
- Emergency Response: Government agencies rely on refrigerated trailers for disaster relief, storing food, medical supplies, and other resources safely.
- Event Management: From weddings to music festivals, refrigerated trailers provide temporary refrigeration for catering and beverage operations.
These trailers are designed to handle various challenges, ensuring reliable performance in different scenarios.
Customization Options
Refrigerated trailers aren’t a one-size-fits-all solution. Many manufacturers offer options to customize both the interior and exterior of trailers based on your specific needs. These trailers can be modified with diverse features to meet various industry requirements, ensuring that clients receive solutions uniquely suited to their operational needs.
Key Customization Features
- Pallet Duty Floors and Walls: Ideal for businesses requiring heavy loads or high insulation.
- Refrigeration Units: Select systems based on your desired temperature range, including freezing, cooling, or dual-mode capabilities.
- Additional Equipment: Generators, high-performance evaporators, or backup power systems can ensure uninterrupted performance.
Working directly with manufacturers to customize your trailer ensures that you get a product specifically tailored to your industry requirements.
Supplier Selection
When selecting a supplier for your refrigerated trailer needs, it’s essential to consider factors such as quality, reliability, and customization options. Look for manufacturers that offer a variety of trailer sizes and configurations to meet your specific requirements. Additionally, consider the level of customer support and after-sales service provided by the supplier.
A reputable supplier will be able to provide you with a perfect solution for your temperature-controlled transportation needs, whether you’re looking for a small refrigerated trailer or a larger unit. With hundreds of options available, it’s crucial to invest in a high-quality refrigerated trailer that meets your business needs and provides a reliable and efficient service.
