What is Refrigerated Trailers

Reefer trailers, or refrigerated trailers, are insulated trailers with built-in refrigeration units. They're designed for cold chain transport, delivering perishable cargo at safe and consistent temperatures. This includes fruits, vegetables, dairy products, meats, chemicals, and flowers. Reefers are equipped with a closed refrigeration system designed to remove heat from a trailer in order to maintain the temperature of a product during transportation. They're not designed to actually cool a product.

Benefits of Refrigerated Trailers

Temperature Control

A refrigerated trailer allows you to keep better control of the environment, more specifically the temperature. These portable trailers allow you to adjust the temperature to suit the contents you're transporting, within the range of –65 to 40 degrees celsius (yes, despite their name these trailers can even keep your contents warm). Because of this, your refrigerated trailer can be used for many purposes, perfect if you sell a wide range of products with different temperature requirements.

Food Preservation

A key benefit of investing in a refrigerated trailer is food preservation. If you're needing to transport perishables, these trailers can preserve the quality of your food until the end of your journey. This feature is perfect for those who need regular refrigerated transportation, for example, those who sell food at a market or a festival. As mentioned before, refrigerated trailers don't just keep your perishables cold, they can also keep them hot. So whatever you're selling, these trailers are the perfect portable storage facility. It's also worth noting that poor preservation could end in ruined goods, which may cost your business to replace.

Flexibility

The flexibility refrigerated trailers give you is unbeatable. They can be placed anywhere with a nearby power source, perfect if you frequent markets or festivals selling perishable foods. Refrigerated trailers also give you plenty of flexibility when travelling and don't limit your journey, allowing you to transport the trailer contents across the country hassle-free and offer fresh produce wherever you end up. Refrigerated trailers allow you full control over what you're transporting, at what temperature, where you're transporting them to and much more. Instead of stressing about food transportation, you can sit back and relax with these cleverly designed reefer trailers.

Cost-Effective

If you're planning to put your refrigerated trailer into frequent use, purchasing one is definitely the most cost-effective solution. Whilst you can hire these trailers, constant hire charges can soon add up and may even amount to more than the purchase price.Not only this, but reefer trailers keep costs down when transporting perishable goods or selling them. Rather than ruining the perishable products and having to throw them out due to poor refrigeration, essentially costing your business, you can keep them at the perfect temperature wherever you are.

Types of Refrigerated Trailers

Standard refrigerated trailer

Standard refrigerated bodies are based on aluminum panels, polyester-glass foil, often called laminate, and the insulator is a rigid polyurethane foam or polystyrene. Standard dimensions are internal width 245 cm, internal height 265 cm, internal length 1340 cm. The thickness of the walls in standard refrigerated semi-trailers is 65 mm or 85 mm in the case of reinforced walls. Such a body can be used for most goods in a wide range of temperatures, from -25c to +25c.

Refrigerated doppelstock / doubledeck trailers

Body with the so-called double floor is mainly used to transport light, delicate products with low weight tolerance, which means that they cannot be restacked or stacked high. Thanks to the system of movable, lifted crossbeams attached to the body walls, it is possible to organize an additional cargo floor for storing goods during transport. This enables the simultaneous loading of up to 66 euro pallets with a height not exceeding 130 cm. The main goods transported on this type of semi-trailers are sweets, food products and cosmetics.

Two-chamber refrigerated trailer

A semi-trailer equipped with a special, movable partition wall attached to the ceiling of the body interior, thanks to which it can simultaneously transport goods that require different temperatures. It has two independent refrigeration units with a wide range of temperatures, thanks to which it is possible to transport both frozen products (-25c / -1c) and goods at positive temperatures (+1c / +25c). The bulkhead wall provides very good insulation, thanks to which two extreme temperatures do not affect the loads transported separately. The weakness of this type of body is the lower than the standard loading space, which can accommodate goods with a height of about 240 cm, as well as the higher curb weight of the semi-trailer, which means that the maximum weight of the loaded goods is lower than in the case of a standard refrigerator.

Flower refrigerated trailer

Flowers and potted plants are transported on special flower carts, the most popular of which are the so-called danish trolleys (cc) or ecc trolleys. Flower semi-trailers are characterized by a wider loading space of 250 cm, thanks to which they are able to accommodate more flower trolleys than a standard refrigerator. Wider space is obtained at the expense of narrower side walls (45mm), which results in lower thermal insulation, which is why it is not recommended to transport goods requiring a transport temperature lower than 0c on this type of body.

Application of Refrigerated Trailers

Events and Festivals
At large public gatherings such as music festivals, food festivals, and outdoor markets, refrigerated trailers are indispensable for storing large quantities of food and beverages at safe temperatures. They provide event organisers with the flexibility to store perishable items on-site, ensuring fresh and safe consumption throughout the event.

Pharmaceutical Transport
The pharmaceutical industry relies heavily on refrigerated trailers to transport medicines, vaccines, and other temperature-sensitive products. These trailers are equipped with precise temperature controls to meet strict regulatory standards, ensuring that vital medications remain effective and safe for use upon delivery.

Catering and Mobile Food Services
Mobile food businesses, including catering companies, use refrigerated trailers to transport and serve food at various locations. These trailers ensure that all food items remain at safe temperatures, reducing the risk of foodborne illnesses and enhancing the overall quality of the food served.

Private Functions
For private functions like weddings, anniversaries, and family reunions, refrigerated trailers offer a practical solution for catering services. They allow for the advanced preparation of meals and keep floral arrangements fresh, adding a layer of sophistication and professionalism to the hospitality offered at these gatherings.

Business Operations During Peak Periods
Businesses such as butchers, florists, and restaurateurs often face increased demand during peak periods like Christmas, Easter, and Valentine's Day. Refrigerated trailers provide additional storage space to manage surplus stock efficiently, ensuring products remain in optimal condition and are available to meet consumer demands without compromising quality.

Components of Refrigerated Trailers

Trailer Refrigeration Unit (TRU)
The TRU is a self-contained refrigeration unit that has its own diesel fuel supply from a tank located underneath the trailer. It also has a small diesel engine and a refrigerant compressor. This device cycles as necessary to maintain the preset temperature while monitoring the inside temperature of the trailer compartment(s).

Insulated Container
Foam insulation is used to insulate the walls of reefer trailers, and the doors seal tightly to keep out air. This guarantees that the temperature stays the same for the duration of the journey.

A Chute for Air
Reefer trailers need adequate air flow to keep the interior at a steady temperature, which calls for air to move freely throughout the trailer. The inner ceiling of some reefers is attached with an air supply duct because of this. Air is distributed from the front of the trailer to the back via this chute. The majority of reefers also include metal channels in the floor that make room for air to flow uniformly underneath the cargo being transported.

Temperature
From a control panel on the driver's side of the TRU, the temperature is controlled and set in accordance with the needs of the consumer. A TRU can provide heating in addition to cooling if necessary to keep the freight at the proper temperature.

Air Ride Suspension
A TRU air ride suspension typically consists of airbags located at each corner of the unit. The airbags are inflated and deflated by a compressor and air tank system controlled by the driver. The air pressure in the bags can be adjusted to level the unit and provide a smoother ride.

How to Choose Refrigerated Trailers

Consider the Size and Capacity

Refrigerated trailers come in various sizes and capacities. Evaluate the volume of cargo you typically transport and choose a trailer size that accommodates both your current and potential future needs. Ensuring that the trailer has ample space without being excessive helps optimize energy efficiency.

Assess the Temperature Control Features

Modern refrigerated trailers offer advanced temperature control features. Look for trailers with precise temperature control mechanisms, ensuring that the internal environment remains consistent throughout the journey. Some trailers come equipped with multi-zone cooling options, allowing you to transport different goods with varied temperature requirements in a single trip.

Check for Energy Efficiency

Energy efficiency is a crucial factor in reducing operational costs and minimizing environmental impact. Choose a refrigerated trailer that incorporates energy-efficient technologies, such as advanced insulation and low-emission refrigeration units. These features not only save on fuel costs but also contribute to sustainable transportation practices.

Ensure Proper Ventilation

Proper ventilation is essential to maintain the quality of certain products, especially fruits and vegetables. Trailers with adequate ventilation systems help regulate humidity levels and prevent the buildup of ethylene gas, extending the shelf life of perishable items.

Evaluate Refrigeration Unit Reliability

The refrigeration unit is the heart of any refrigerated trailer. Prioritize reliability when selecting a trailer by opting for reputable brands known for durable and efficient refrigeration units. Regular maintenance is crucial to keep the unit in optimal condition, so inquire about the availability of maintenance services and spare parts.

Check for User-Friendly Features

Consider features that enhance the user-friendliness of the refrigerated trailer. This can include easy-to-use temperature monitoring systems, remote control options, and user-friendly interfaces. A trailer with intuitive features can contribute to the efficiency of your operations and reduce the risk of errors.

The Right Way to Load a Refrigerated Trailers

01/

Pre-cool your cargo
Reefer semi trailers are not designed to chill warm goods, but rather to keep chilled goods cool. In other words, if items are meant to be kept at 40 degrees Fahrenheit during their journey, they should be at that temperature when they're loaded. This is best for them and also for the semi trailer's refrigeration unit.

02/

Minimize cargo dock time
Ensuring that your cargo is pre-cooled isn't helpful if it's then allowed to sit on a warm loading dock for an extended period. As much as possible, time your loading so that cargo can be moved from cold storage to your cold semi trailer quickly and efficiently.

03/

Pre-cool the cargo space
The residual heat in the floor, walls and ceiling of a reefer semi trailer can transfer to the cargo you load. Consequently, it's important to get the trailer to the desired transport temperature before you load it. A certain amount of warming may occur during the loading process, but it will be minimal and the trailer's cooling unit can catch up easily.

04/

Ensure proper spacing
The key to keeping goods cool in a reefer semi trailer is airflow. Anything that inhibits airflow creates the risk of hotspots developing in the trailer. Consequently, you should position your cargo so that there is at least 2 inches of space between the goods and the trailer sidewalls, 4 inches of clearance from the rear doors, and 9 inches of overhead clearance.

05/

Use pallets if appropriate
If the floor of the trailer you're using is flat, you should load cargo onto pallets so that air can flow easily under the goods. Again, unimpeded airflow is essential.

06/

Be mindful of cooling equipment function
It's important that you understand how the cooling system on your reefer semi trailer works and ensure that cargo doesn't interfere with that work. For example, goods should not block the cooling system's evaporator outlet.

Emerging Trends in Refrigerated Trailers

Sustainability and Environmental Consciousness
People have become aware of the environment and its consequences on it. Therefore, people are now opting for more eco-friendly gadgets than usual ones. These fridges use coolants that are environment safe and authorized by the government to use. The refrigerator now uses these gases as per government recommendation to keep things cool. These eco-friendly gases such as hydrofluorocarbons (HFCs) maintain the temperature of the earth preventing them from rising global warming. So, when people buy fridges, they think about the Earth and pick ones that don't make it too hot.

Internet of Things (IoT) Integration
The integration of the internet has touched almost every part of our lives. And, refrigerated trailers are not left untouched. These trailers are equipped with smart temperature sensors and GPS devices. It shares instant information about the temperature and route of these trailers. This also allows users to check and control things remotely. It also helps to predict when the trailer needs fixings and indicate if there are any problems in the trailers. So, it's like giving these trailers a superpower to stay in perfect shape and do their job better!

Data-Driven Optimization
The integration of emerging technology in these refrigerated trailers, helps them perform much better. The use of telematics and a data-driven approach helps make the refrigerated trailers more advanced. It gives access to users to monitor and change the temperature in real-time, saving the food and products right before they get frozen or humid. Moreover, by using these data it plans the fastest and most optimal route, reducing the consumption of fuel and making the working efficient. In other words, it's like having smart fridges that not only will save you money but also keep the food fresh and safe to eat.

Advanced Cooling Technologies
With new and improved technologies the way refrigeration trailers work is also changing. They are becoming advanced with the betterment of technologies. Getting efficient in keeping things cold with, less energy, and remote temperature controls. Some of these trailers use coolants like liquid nitrogen to keep them fresh for long. Also, refrigerated trailers that work on an electric basis are more in demand than diesel ones. These electric trailers help in reducing noise and air pollution. So, our fridges are getting cooler, saving energy, and helping the environment!

How to Maintain Refrigerated Trailers

Practice Routine Vehicle Maintenance
As a company that relies on refrigerated trailers for daily business operations, vehicle maintenance issues such as unexpected breakdowns, wear and tear, condenser or evaporator problems, temperature sensor malfunctions, and blocked airflows will disrupt the ability to optimize the use of refrigerated trailers.It is therefore important to have a routine maintenance plan that is followed to prevent unexpected downtime from maintenance issues and breakdowns.

Clean the Interior
With all the kinds of temperature-sensitive products being transported, reefer trailers can get messy. Once emptied, reefer trailers need to be cleaned using a pressure washer with water mixed with industrial refrigeration detergent because the leftovers, dirt, and other messy things can hinder proper airflow within the trailer, risk the temperature consistency in the trailer, and put products at risk of spoilage and damage.

Perform Pre-trip Inspections
Interior inspections include checking if drains have clogs, walls have cracks or cuts, and air chutes have holes. Exterior inspections include checking for oil leaks, faults in hoses and belts, unusual engine noises, trailer body damages, light malfunctions, and low tire pressure.

Stay Fully Fueled Up
Before transporting products be sure there is a full fuel tank to prevent the reefer trailer from running out of fuel. If the reefer runs out of fuel, it also runs out of cold, placing the perishable products at risk of spoilage and can cause major mechanical issues as the cooling unit will pull accumulated moisture out of the lines if fuel is low.

FAQ

Q: What is a reefer trailer?

A: A reefer trailer is also known as a refrigerated trailer. Primarily a dry van, reefers are built with insulation and refrigeration capabilities for the transport of perishable and temperature-sensitive goods. While these goods aren't meant to be heated or cooled, reefers are able to maintain a pre-set temperature. Normally truckers invest in reefer trailers to eliminate product spoilage in their loads.
Reefer trailer's main components include a reefer unit, an insulated box, reefer air chute, air ride suspension, and tire inflation system. Reefer unit's important components include the engine, compressor, evaporator, and condenser. Reefers are typically 53 foot long but are also available in a variety of sizes.

Q: What can a refrigerated trailer do?

A: A refrigerated trailer is meant to maintain the temperature during the transport of perishable and temperature-sensitive goods. The purpose of refrigeration is to remove heat, take it from one place, transport it, and release it to another. Since reefers are able to collect and pump heat, they can be used to heat and cool shipments.

Q: What types of things to reefer trailers transport?

A: Reefer trailers are used in the transport of goods that are temperature-sensitive and/or perishable.

A: You can buy a reefer trailer using our online inventory. Ranging from new to used trailers, we offer a wide selection of reefer trailers. Once you find the reefer trailer you need, you can call or e-mail us regarding any purchase.

Q: How does a reefer trailer work?

A: In a reefer trailer, its compressor is driven by a small diesel engine. The compressor draws gaseous refrigerant in and compresses it. This pressure is then able to liquefy into gas. The liquefied gas then gives off heat to the body of the compressor and the air. After this process, the trailer is still relatively warm, so it's then pumped to the condenser.Once pushed into the condenser, it goes through a heat exchanger process. During this phase, warmth flows from the liquid to the walls and fins of the tubing. This process works similarly to the way a radiator cools an engine.

Q: How to maintain a reefer trailer?

A: Keep It Clean.This includes using a detergent to wash the interior since residues from meats can cross-contaminate vegetables, fruits, and other meat. This also ensures that the trailer is completely emptied of dirt, pallet wrap, and anything else that can reduce the airflow of the reefer trailer.

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

A: One common school of thought is that a reefer trailer should be able to provide an average of 40,000 hours or about 8 years on the road based on between 4,000 and 5,000 hours of use annually.As a good practise, once a week, the trailer should be completely rinsed – ceilings, walls, floor, – then a heavy duty, long-cling cleaner/sanitiser with thickening technology applied to all surfaces. Leave this to dwell for the specified time, then rinse out thoroughly.

Q: What are good hours on a reefer 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: How do you remove air from a reefer?

A: In order to remove this air, it is necessary to vacuum the interior of the refrigeration system, sometimes due to subjective and objective reasons, the vacuum inside the refrigeration system is not enough to meet the requirements, leaving a small amount of air in the system.

Q: What is the best thing to clean an enclosed trailer with?

A: If your trailer is painted, use soap made for washing cars to retain the paint's gloss. Hose down the trailer with water and use a long-handled scrub brush or mop to apply the soap, then rinse. To remove stubborn materials like yard waste or caked-on mud, a power washer and detergent usually does the trick.

Q: How does a refrigerated trailer work?

A: Refrigerated trailers use three core components for their cooling system: Compressor. A small diesel engine powers the compressor, which draws in gaseous refrigerant and compresses it. This compressed refrigerant liquefies into a high (hot) temperature gas and gets passed to the condenser.

Q: How long does it take a reefer trailer to cool down?

A: How long does it take a reefer to cool down? With the doors closed, the average reefer takes around two hours to cool down. If the outside temperature is extremely hot, it can take a longer time.One common school of thought is that a reefer trailer should be able to provide an average of 40,000 hours or about 8 years on the road based on between 4,000 and 5,000 hours of use annually.

Q: How long will a 12 volt RV refrigerator run on battery?

A: Assuming a standard RV battery voltage of 12 volts, your fridge requires 48 Ah for 8 hours of operation (576 Wh / 12V = 48 Ah). Given this example, with 50 Ah available, your battery could run the fridge for approximately 8 hours, assuming no other loads are drawing power from the battery.

Q: What temp should a reefer be set at?

A: According to Hale, these reefer trailer temperature ranges are considered the best for the following types of produce: 32-36˚F for greens, berries, apples, cruciferous vegetables, grapes, and stone fruits. 38-40˚F for avocados and cranberries. 40-45˚F for potatoes, green beans, and sweet potatoes.

Q: What is the life expectancy of a reefer 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.You can also haul dry loads or other temperature-sensitive products with your reefer, which gives you more flexibility regarding which loads you pick up and which routes you can take.

Q: What is the difference between continuous and start stop on a reefer?

A: Most reefer trailers can run in two different modes: Start-stop mode means that the refrigerator unit only burns fuel and decreases the temperature when it reaches a specific threshold. Continuous mode means the refrigerator unit continually burns fuel and keeps the temperature low 24/7.

Q: Why do reefer loads pay more?

A: Refrigerated shipments typically pay more than dry van freight because the items being transported often require sensitive temperature control. For example, most food and beverage companies ship their goods in a refrigerated trailer kept at 32-36°F, which is about the same temperature as your fridge at home.

Q: How often should you service a reefer trailer?

A: Inspections. While reefers don't require as many inspections as dry vans, a pre-trip should be performed at least once every 1,000 hours for older units. However, newer reefers can go much longer than this. As with dry vans, reefer trailers need to have a thorough check done by an authorized service center.

Q: How much fuel does a refrigerated trailer use?

A: How Much Fuel Does a Reefer Trailer Use? Most reefer tanks have a 50-gallon capacity. Since reefers burn around 0.75 gallons of fuel per hour, most reefer tanks must be filled in two to four days. The truck's distance doesn't affect reefer tanks' fuel consumption since they are closed systems.
