What are Small Refrigerated Trailers and Freezer Trailers?

Refrigerated and freezer trailers are specialized vehicles designed to transport perishable goods at specific temperatures. These trailers ensure that the products inside remain at a consistent temperature, regardless of external conditions.

Definition and Basic Functionality

At their core, both refrigerated and freezer trailers are insulated trailers equipped with a cooling system. They are designed to maintain a set temperature range, ensuring the goods inside remain fresh and safe for consumption or use. The cooling system can either be mechanically refrigerated using compressors and condensers (our preference) or cold plate systems in the walls.

Difference Between Refrigerated and Freezer Trailers

The primary difference between the two lies in their temperature range and purpose:

Refrigerated Trailers: Also known as “reefers,” these trailers maintain temperatures above freezing, typically between 35°F to 70°F (2°C to 21°C). They are ideal for transporting goods like fresh produce, dairy products, and pharmaceuticals that require cool but not frozen conditions.
Freezer Trailers: These trailers maintain sub-zero temperatures, typically below 32°F (0°C). They are designed for goods that need to be kept frozen, such as meat, seafood, and certain medical supplies.
Cooler Trailers brand are unique because they will do both freeze or cool with just a 115-volt refrigeration unit.

Why are they Essential?

The modern global market demands swift and efficient transportation of goods. With perishables, the challenge is not just speed but also maintaining product integrity.

Importance in Food and Pharmaceutical Transportation

Both the food and pharmaceutical industries have stringent standards for product safety and quality. Refrigerated and freezer trailers ensure that these products are transported in optimal conditions, preventing spoilage and ensuring that medicines remain effective.

Our trailers have food grade USDA and NSF approved walls, floor and roof to meet and surpass any inspectors wish list.

Role in Reducing Food Wastage

A significant amount of food is wasted every year due to improper storage and transportation. By maintaining the right temperature, these trailers play a pivotal role in reducing this wastage, ensuring that food reaches consumers in the best possible condition.

Use in Events and Mobile Businesses

From food trucks serving gourmet dishes to mobile vaccination drives, refrigerated and freezer trailers offer a flexible solution for businesses and events on the go. They ensure that products are kept at the right temperature, even in remote locations or during large-scale events.

Types of Refrigerated and Freezer Trailers

The world of refrigerated transportation is diverse, with various types of trailers catering to different needs.

Transport Refrigeration vs. Off The Shelf Units

Transport Refrigeration: These trailers come with an integrated refrigeration system. They are designed to handle the rigors off the road and ideal for long-haul transportation.
Off The Shelf Units: These are split units meaning a condenser and evaporator in separate housings joined together by local installer with copper lines that are prone to leak do to design. This is good for stand alone application but not for over the road use.

Single Temperature vs. Multi-Temperature Units

Single Temperature: These trailers maintain a consistent temperature throughout. They are simpler and often more energy-efficient.
Multi-Temperature: These trailers have compartments with different temperature settings. They are ideal for transporting a variety of goods with different temperature requirements in a single trip. We have an optional moveable bulkhead wall with fan kit that we use for our multi- temp folks.

Comparison of Popular Products

Cooler Trailers: Renowned for its insulated truck body durability, aluminum chassis and advanced temperature control features since 1997.
Cargo Trailer Retrofit style: Problems with wood leading to mold & mildew. Not efficient as a freezer and will not get very cold.
Window Unit Gimmick: Maybe an option for you if your a gambler and don’t mind rolling the dice with your hard earned money or this is just a hobby for you. Otherwise stay with a professional solution that is proven to work.

Selecting the Right Trailer for Your Needs

Choosing the right refrigerated or freezer trailer is crucial for the safe and efficient transportation of perishable goods. Here’s what you need to consider:

Size Considerations

Volume of Goods: Estimate the volume of goods you’ll be transporting regularly. Ensure there’s some extra space to accommodate occasional larger loads.
Vehicle Compatibility: If you’re considering a small refrigerated trailer, ensure it’s compatible with the vehicles you intend to attach it to. Find out your vehicles Gross Vehicle Weight Rating or (GVWR) rating so you know how much weight your vehicle can tow.

Temperature Requirements

Type of Goods: Different goods have different temperature requirements. For instance, dairy products and fresh produce might need cool temperatures, while meat and seafood require freezing conditions.
External Climate: Consider the external climate, especially if you’re transporting across varying weather conditions. Some trailers offer better insulation than others.

Duration of Use

Short vs. Long Hauls: For shorter trips, a pre-cooled unit might suffice. However, for longer hauls, especially across states or countries, a transport refrigeration system is more reliable.

Benefits of Using Small Refrigerated Trailers

Small refrigerated trailers offer several advantages over their larger counterparts and other forms of cold storage:

Mobility and Flexibility

Location Independence: These trailers can be moved to different locations as per demand, making them ideal for events, farmers’ markets, or pop-up sales.
Ease of Use: Their compact size makes them easier to maneuver, especially in urban settings with tight spaces.

Cost-effectiveness

Lower Initial Investment: Small trailers are generally more affordable than large trucks or permanent cold storage facilities.
Reduced Operational Costs: With fewer goods to cool, they often consume less energy, leading to lower operational costs. For example 70% less on insurance for trailer vs truck.

Energy Efficiency

Advanced Technology: Many modern small trailers come equipped with energy-efficient cooling systems, reducing electricity consumption and environmental impact.

Potential Drawbacks and How to Overcome Them

While small refrigerated trailers offer numerous benefits, they come with their own set of challenges:

Maintenance Costs

Regular Upkeep: Like all vehicles, these trailers require regular maintenance to ensure their cooling systems function optimally.
Solution: Set a regular maintenance schedule and stick to it. Cooler Trailers brand only need to keep the coils clean ever so often.

Limited Storage Compared to Large Units

Space Constraints: Their compact size means they can’t accommodate the same volume of goods as larger trailers or trucks.
Solution: For businesses that see fluctuating demand, consider maintaining a mix of small and large trailers. Use the smaller ones during off-peak times and the larger ones during peak seasons.

Solutions to Common Problems

Breakdowns: Always have a backup plan in place. Consider partnering with a rental service for emergencies.
Temperature Fluctuations: Invest in trailers with advanced temperature monitoring systems. Regularly calibrate and check these systems to ensure accuracy.

Innovative Uses of Refrigerated Trailers

Refrigerated trailers aren’t just for transporting perishable goods. Their versatility has led to some innovative applications in various sectors and rental income opportunities for savvy entrepreneurs:

Mobile Bars or Cafes

With the rise of the food truck culture, entrepreneurs are turning refrigerated trailers into mobile bars or cafes. These trailers ensure beverages and perishable ingredients remain fresh, allowing businesses to serve gourmet dishes and chilled drinks on the go.
