The Importance of Airflow Management in Reefer Trailers

The Importance of Airflow Management in Reefer Trailers

Airflow management in reefer containers and trailers – It may not seem like something that an average person would think about. Airflow in a refrigerated container versus that in a traditional container is not something that an average person would think about. But if you are moving fresh produce or other refrigerated products, it is a very important subject.

There is a huge difference in refrigerated (reefer) trailers and containers. The air flow moves differently in each of these containers, and it makes a difference in how well the cargo is preserved. Poor air flow circulation can cause the product to be partially or entirely ruined before it arrives at its destination.

Airflow Management in Trailers vs. Containers

Airflow in a reefer trailer is pushed in through the top of the trailer and circulated from the back of the trailer to the front. Along the way, the air becomes warmer because of the distance it has to travel before being recycled through the refrigeration unit again. This means that much of the product at the front of the trailer is being held at a warmer temperature than that at the back. This can lead to product loss and contamination.

Airflow in a reefer container is handled much differently. The cold air is pumped into the container from the bottom of the unit. This is done because of the way the floors are made in the container. Known as a “T” floor, the air flows more evenly through the container and remains cooler throughout the recycling process. This results in the product being kept in a more stable and safer temperature environment.

Reefer trailers do not use the T floor in their units because of the additional weight this adds. Trailers are restricted by weight limits, and reefer trailer manufacturers would prefer more space in their trailers than more weight. So, the top airflow system is used.

Peace of Mind with Containers

If you are concerned with the safety and quality of your cold storage units, you may wish to convert to cold storage or reefer containers instead of using trailers. The containers will protect the product more effectively and reduce overall spoilage.

Portables 360 offers two different types of reefer containers. Each container is capable of easily maintaining a temperature of -20 degrees to 70 degrees. This allows companies to transport a wide variety of products using the same containers. Investing in refrigerated containers is a very cost-effective way to transport your product safely while reducing loss.

The Proper Way to Pack a Portable Storage Container

The Proper Way to Pack a Portable Storage Container

Portable storage containers have found many uses in recent years. In addition to shipping goods, these containers have been used to construct homes and hotels, build offices, create emergency shelters, and generate grow areas for specialty plants and foods.  

Portable storage containers have become workshops and garages, on-site offices, and even training facilities for fire and rescue workers. It is truly amazing what can be done with a shipping container. 

However, when you get back to basics, these shipping containers are made for just that – shipping goods. Many people have found that a portable container makes the perfect space for shipping their personal or business belongings over long distances.  

Portable containers are weatherproof, solidly built, and some even have refrigeration if you need to keep your goods at a certain temperature during transport. Knowing how to pack a storage container is important. Regardless of how sturdy these containers are, for the best protection of your items, you should: 

Pack the Heaviest Items in the Middle 

To keep your container balanced while it is being picked up and set down, it is always better to pack your heaviest items in the middle of the container. Make sure that you secure them to the container so that they do not shift when the container is being moved.  

Pack all of your other belongings around the heavy items until the container is full. Make sure that you have space to open and close the door. You should always secure boxes and other items with bungee cords or stops, even if they are lightweight.  Adjustable straps are excellent for keeping items from shifting during travel. 

If you are packing a refrigerated container, you will want to make sure that the airflow is not interrupted in the container. The air conditioning works by circulating the cold air throughout the trailer.  Usually this is accomplished through vents in the flooring. Make sure that all of your vents are open and that nothing is blocking the hoses running the system. This will help protect your items from temperature damage. 

If you are traveling over long distances, or through areas where there will be weather changes from your current temperatures, make sure that your items are protected from the weather change. Unless you have already insulated the shipping container, there is a risk that the container could become very hot or very cold when you are moving to a different climate. Items like electronics, vinyl records, DVDs or CDs can all be negatively impacted by temperature changes. If the items you have packed in the container will be harmed by severe temperature changes, you need to take precautions. 

The final thing to remember when you pack a storage container is to put all the light or breakable items at the top of boxes or bins. Moving can be difficult for delicate items.  Take your time and ensure you have protected and secured everything as well as possible.

How Does a Refrigerated Trailer Work

How Does a Refrigerated Trailer Work

Everyone understands that certain products need to be kept at a cooler temperature while they are being transported. Ice cream, for instance, cannot travel in a shipping container that is not held at 32 degrees or colder. Produce, some beers and wine, and meat all must be transported under controlled temperatures. 

Businesses use refrigerated shipping containers to move their product safely and at the right temperature. But how does a refrigerated shipping trailer work? The system is quite simple and only consists of three major components. 

How a Refrigerated Shipping Trailer Operates 

The first thing that you must understand is that any refrigeration unit works on a closed system. Having a closed system is essential for maintaining temperature control. The system must be sealed for it to work properly since part of the refrigeration process includes the use of gas. 

The cooling unit on a refrigerated shipping trailer contains three major components: The condenser, the compressor, and the evaporator.  

The compressor is a small engine that powers the refrigeration unit. The job of the compressor is to take in the refrigerant and compress it into a liquid. While the refrigerant is being compressed into a liquid, the heat is being released. This is one of the reasons that you will feel the heat coming off of the compressor while it is working.  

The condenser is the next component of the system. The condenser receives the liquid from the compressor and then cools it by running it through the tubing and cooling it with a fan. This part of the cooling system works very similarly to a car radiator. 

The final component of the cooling unit is the evaporator. The evaporator receives the cooled liquid and causes it to evaporate so that it can cool the designated area. The cooling unit on these trailers works similar to the cooling units on your homes.  

Cooling a trailer is basically that simple. Refrigerated shipping trailers take other precautions as well to make sure that the cooling system works properly and manages to keep all the product at the same temperature. 

Insulation and Airflow

A refrigerated shipping trailer is insulated in a way that when the trailer is cooled, it can maintain the right temperature. Additionally, many of these trailers are specially designed so that the cool air flows throughout the trailer at all times and not just blowing at one end. If the cool air is not circulated through the unit, some of the product may be affected. 

If you need to transport or store goods at a controlled temperature, a refrigerated trailer will be your best choice. These containers are perfect for transporting products as well as for using as stand-alone cold storage units for restaurants, stores, and personal hobbies like homebrewing.

Growing plants in shipping containers has become increasingly popular as an economical choice for having a shipping container garden.  Shipping containers are being used for building homes, storage units, and even health care clinics in remote destinations. Many organizations have found these upcycled containers to be perfect for transporting goods.  Setting up service centers in disaster zones is another vital use for containers. Now a new use has been found for shipping containers: farming or gardening. 

Shipping containers are a perfect solution for gardening, specialty crops, or making space to grow fresh food in an area without available land. These containers can be fitted with shelving, grow lights, watering systems, and everything else you would need to grow fresh food and specialty plants or flowers.  Portable360 can modify your shipping container with the following add on options.

Imagine the possibilities.  

Imagine a restaurant creating a shipping container garden behind their venue so that they have “fresh to table” options. An apartment complex can start a community garden for residents to enjoy. Farmers that want to increase crop output or raise specialty crops can use containers and reserve their ground space for other plants.  

You can control the temperature and growing conditions in a shipping container much easier than having to rely on the weather. Refrigerated containers are perfectly insulated.  If you need ultra-controlled growing conditions, you can opt for a refrigerated container. 

A New Resource For Schools  

Many schools have stopped offering classes or clubs related to gardening or agriculture. Many school districts try to devote their limited space to technology and science. A shipping container garden, however, can be the perfect option to teach children how to grow their food. 

A container garden is also the perfect way to teach children the science behind growing plants, soil management and conservation.  Even teaching innovative growing methods like hydroponics is possible in a recycled shipping container.

Cost Effective Farming Method 

One of the best benefits of a shipping container garden is the fact that these containers are very affordable. It is just more cost-effective to purchase a new or used shipping container and convert it into a growing area than it is to construct a greenhouse. Everyone can benefit from how affordable these containers are when used as a place to grow crops.  The durability of a mobile storage container garden versus a traditional greenhouse is also a huge benefit.

Another benefit to growing food in a recycled portable container is how quickly you can bring your crops to harvest. In a controlled growing space like a shipping container, you can bring your crops to harvest in a matter of weeks for fast-growing foods because you always control the growing conditions. You do not have to worry about pest infestations, wild animals, or drought and heat issues slowing your growing season.
