Chutes are in common use in tall buildings to allow the rapid transport of items from the upper floors to a central location on one of the lower floors or basement. Chutes may be round, square or rectangular at the top and/or the bottom.
Akin to these, man-made chutes, such as the timber slide and log flume, were used in the logging industry to facilitate the downstream transportation of timber along rivers. These are no longer in common use. Man-made chutes may also be a feature of spillways on some dams. Some types of water supply and irrigation systems are gravity fed, hence chutes. These include aqueducts, puquios, and acequias.
His expertise includes managing offshore catering business, offshore reefer containers, AI technology, offshore gas tanks, A60 pressurized cabins, etc. His contributions have helped establish MGS, in partnership (joint venture) with Thermo King and Honeywell to produce state of art Offshore Reefer Container products.Return air is the temperature of air that has been circulated through the reefer. In low-temperature mode, the majority of common refrigeration units control ‘return temperature’ using a two-point switching method.
Therefore, it is safe to say that the respiration gasses emitted by non-climacteric fruit are much lower than climacteric fruit. As such, the need for ventilation of non-climacteric fruit becomes far less.
The Ice Storm Offshore Reefer Container container by MGS maintains a refrigerated container temperature setting that ranges from -30c to +20c with a humidity controller to meet the requirements of different perishables.
When the ‘return air’ temperature rises to approximately 0.5°C above the nominal value, the refrigeration unit starts up again, and the entire process is repeated.
One way to ensure stable temperature moderation during perishable good transportation is by using an offshore reefer container or offshore refrigerated container.
With the ability to facilitate fresh air exchange, ventilation also helps remove unwanted heat, ethylene, carbon dioxide and most gases produced by the cargo.
In summary, reefer containers are designed to automatically control refrigeration using the supply air sensor to detect and critically manage temperatures within a 0.5°C (0.9°F) range, or better, under most conditions.
With over 13 years in the shipping industry, he has had a significant contribution to Malaysia’s oil and gas industry in the engine and boat supply sector. A graduate (Business) from KDU, Jason Tan, is the current Business Director (Sales) for MGS Icestorm and has been associated with the company for the past 10 years. At temperatures below 10°C, this results in more frequent defrosting periods and frequent interruption of the circulation fans. In turn, less fresh air intake shows that:
Generally, fresh air ventilation helps to remove accumulated respiration gasses, like carbon monoxide and ethylene, emitted by the cargo as a result of the ripening process of perishables.
As a result, climacteric fruits have a high level of respiration, for example, pears, mangoes, avocados and bananas. Non-climacteric fruits include citrus, grapes, cherry and watermelon.Ventilation helps deliver fresh air to perishable cargo that is being transported. It is also the simplest and most cost-effective way to help prevent condensation in your cargo.
What is the ventilation of reefer container?
Ventilation in reefer containers Ventilation essentially refers to the replacing of air inside a container with air from the outside surrounding environment. For the most part, the fresh air intake capacity of most reefer containers varies between 0 and 180 m3/hour (50 Hz).
Consequently, once the nominal temperature is reached, the refrigeration unit switches itself off. It leaves only the fans responsible for circulating the air in the reefer container running.
Overall, fresh air ventilation is especially useful for products that produce high levels of ethylene, such as tomatoes and apples. However, excessive ventilation can result in the freezing of the evaporator coils and will necessitate additional defrosting to remove ice build-up.Ventilation essentially refers to the replacing of air inside a container with air from the outside surrounding environment. For the most part, the fresh air intake capacity of most reefer containers varies between 0 and 180 m3/hour (50 Hz). Fresh air affects the efficiency of refrigeration installation as the evaporator cooling coil is designed to eliminate humidity from the air inside the container. Temperature is essentially the most important factor in preserving the freshness and quality of perishable commodities. This is because the rate of respiration is directly proportionate to the rate of deterioration, which typically increases exponentially as temperatures increase.
Fruit, for example, can be divided into climacteric and non-climacteric. Climacteric fruits continue to ripen after harvest, while non-climacteric fruits stop ripening after harvest.
However, the amount of fresh air required typically depends on the tolerance of the product to low levels of oxygen and high levels of carbon dioxide and ethylene. Additionally, it also depends on the rate at which the product respires and produces ethylene.A standard air chute runs the cold air that comes from the refrigerated unit through the middle of the trailer’s ceiling blowing it to the back of the trailer.
Two of our patented performers paired together to prevent damage to the center chutes, as well as the header. Ideal product for non-refrigerated back-hauls!Two tubes designed to prevent airflow from blowing directly against the hot trailer ceiling, allowing for less heat transfer. Also, tubes lay flat against the trailer walls when not in use, preventing possible damage to the chutes during loading and unloading.Reefer containers play a vital role in the global supply chain. They carry food, medicines, and electronics wherever needed. Designed to carry such temperature-sensitive goods, reefers are undoubted one of the essential container types out there.

Refrigerated truckload trailers — commonly referred to as reefers — are just as the name promises: insulated, full truckload trailers with a refrigeration unit in the front (nose).As soon as produce comes out of the ground (or off the tree), the clock starts ticking. These products must be delivered by a certain date or the food will spoil and the shipper won’t make any money.Though reefers are often used to maintain cooler temperatures, they are also used to heat air. In the winter, shippers use reefers to protect temperature-sensitive products from freezing.
One of the requirements in the Sanitary Transportation rule in FSMA states that refrigerated trailers have to be equipped temperature recording equipment. Though there are a few exemptions, this applies to most refrigerated truckload shipments.
Trailer chutes lay flat against the trailer ceiling and inflate when in use. They are easy to install, made of highly durable material, protect against temperature variance and create more efficiency, which reduces diesel consumption.
Meet the winners of the 2022 Carrier of the Year awards from Coyote Logistics. These trucking companies stepped up to keep our network moving all year long.For instance: sweet corn needs to be immediately cooled after harvest to prevent sugar from turning to starch (reducing quality). To do that, corn shippers often dump ice on top of the corn after harvest, then again once it is loaded in the trailer, where it will slowly melt during transit. The FSMA covers seven major rules. One of the seven — the Sanitary Transportation rule — establishes specific requirements directly related to refrigerated truckload shipping. Another example: ice cream comes off the production line at a higher temperature than it ships at. If the shipper does not already have the ice cream pre-cooled to the appropriate temperature, it doesn’t matter if the driver has their trailer pre-cooled to a -20 degrees Fahrenheit deep-freeze — there is a chance the product will be rejected upon arrival.”Training of carrier personnel in sanitary transportation practices and documentation of the training. Carriers covered by the rule are required to provide food safety training to transportation operations personnel when the carrier and shipper agree that the carrier is responsible for sanitary conditions during transport.”
Many products require continuous cooling. Ripening produce, for instance, generates heat, and requires a steady stream of cool air to maintain a consistent temperature.
Do all reefers have chutes?
Every reefer has what is called an air chute. An air chute is basically a shaft that runs across the trailer’s ceiling (see previous photo). The chute is what blows sizeable amounts of cold air from the reefer unit all the way to the back of the trailer.
For more information on how to ensure compliance to the Sanitary Transportation rule for your small business, the FDA published this helpful guide, as well as this training module for carriers.With dry van freight, the loading, shipping and unloading process is pretty similar across most products. That is not the same with temperature-controlled freight — different commodities can have very different refrigerated shipping requirements (particularly produce).
This includes carriers local to produce regions, as well as those migrating from other capacity markets. The net impact is spot rate inflation and capacity shortages for refrigerated truckload services.
Whether you’re a dry van carrier looking to get into the reefer market, or a truckload shipper trying to boost your knowledge, every industry professional should have an understanding of this important mode.The reefer truckload market can be a great way to expand your business and access new opportunities, but before you buy a trailer and “ride the wave” of produce season, here are a few things to remember:
Variations in air pressure create air flow. As air from inside the trailer passes over the evaporator coil, it removes heat and redistributes the now colder air back throughout the trailer.
Furthermore, the refrigerated truckload market is comparatively smaller than the dry van market. Less supply and higher seasonal demand make rate and capacity swings even more volatile.The refrigerated truckload market follows most of the same patterns as the wider truckload market — most of which is dry van capacity — but there are a few differences that make temperature-controlled shipping a little more complex.
“The measures taken during transportation to ensure food safety, such as adequate temperature controls, preventing contamination of ready to eat food from touching raw food, protection of food from contamination by non-food items in the same load or previous load, and protection of food from cross-contact, i.e., the unintentional incorporation of a food allergen.”

Running the refrigeration unit in cycles reduces diesel consumption, but also creates more temperature variance.”The design and maintenance of vehicles and transportation equipment to ensure that it does not cause the food that it transports to become unsafe. For example, they must be suitable and adequately cleanable for their intended use and capable of maintaining temperatures necessary for the safe transport of food.” Learn how to get guaranteed revenue and minimize empty miles with My Smart Routes, the new route optimization program for carriers from Coyote Logistics. While perishable foods are always shipped in refrigerated trailers, many products that you won’t find in your refrigerator require temperature control — to name a few:
What is trailer chute?

Every March, it kicks off in the southern U.S. as fresh fruits and vegetables become ready for harvest. Produce volumes continue to increase and spread across the country throughout the spring and summer.Learn about the different kinds of trailer repositioning opportunities available, how they can make you money and why Coyote is a great place to find them.
What is an air chute on a reefer?
Air chutes were designed to direct the air within a reefer in an ideal flow to achieve consistent temperature throughout. They are attached to the roof of the trailer, receive the air from the refrigeration unit and deploy it through the sides and back.
For refrigerated carriers, FSMA requires that they must be able to provide documentation of their trailer’s temperature throughout transit — simply put, all drivers need to have a “downloadable” refrigerated trailer.Once produce season kicks off, many reefer carriers will move some — or all — of their capacity to service these high-paying, seasonal produce shippers.
While the hottest produce shipping regions will experience these more intensely (e.g. southern Florida in April), there is a ripple effect across the country.

What is a air chute?
An air chute is installed in your attic to allow air to flow through your soffits, past your attic insulation and through to the roof vents. Without air chutes, your attic will not breathe. A poorly vented attic can cause energy loss, ice dams, mold and rot.
Coyote has been named a 2022 Leading 3PL for Technology by Global Trade magazine for our “Tech + Humanity” approach to logistics, including our free TMS.Understanding the commodity specifications is extremely important for carriers since they are responsible for the product from the moment it is loaded onto their trailer until it is unloaded.
“Maintenance of records of written procedures, agreements and training (required of carriers). The required retention time for these records depends upon the type of record and when the covered activity occurred, but does not exceed 12 months.”
It is also a great way to help determine if a product was damaged in transit or not. This can help fairly settle claims and help protect compliant drivers and carriers against liability.
What is the function of chute?
Chutes are in common use in tall buildings to allow the rapid transport of items from the upper floors to a central location on one of the lower floors or basement. Chutes may be round, square or rectangular at the top and/or the bottom.
Since timeliness is so critical, produce shippers are generally very knowledgeable about how to move their freight from the farm to the store, and use pricing strategies to ensure capacity.Food shippers should familiarize themselves with all seven rules, but reefer carriers should be primarily concerned with the Sanitary Transportation rule. According to the FDA, the FSMA final rule on Sanitary Transportation establishes four specific requirements.
What is the purpose of chute?
Chutes are in common use in tall buildings to allow the rapid transport of items from the upper floors to a central location on one of the lower floors or basement. Chutes may be round, square or rectangular at the top and/or the bottom.
This month, we released personalized scorecards, an interactive help center, facility reviews, instant credit applications and CoyoteGO guidebooks for shippers and carriers.Air chutes in a reefer trailer (aka trailer chutes or a chuted trailer) are flexible air ducts connected to the refrigeration unit that run along the top of the trailer. Chutes act as a ventilation system to evenly distribute chilled air throughout the trailer.
In 2016 — as a part of the Sanitary Food Transportation Act of 2005 (SFTA) and the Food Safety Modernization Act of 2011 (FSMA) — the Food & Drug Administration (FDA) published the Sanitary Transportation Rules.
Two tubes designed to prevent airflow from blowing directly against the hot trailer ceiling, allowing for less heat transfer. Also, tubes lay flat against the trailer walls when not in use, preventing possible damage to the chutes.And that’s where air chutes come in. Air chutes can play a significant role in keeping the climate within the trailer cargo space at optimal conditions because they distribute air evenly and consistently throughout the trailer to help reduce the risk of a load loss. But are they right for your reefer operation? That’s what we want to dive into in this article.

Do reefer containers have ventilation?
Therefore, reefers are kept ventilated by fresh air. Additionally, humidity plays also an essential role in keeping cargo safe. A dehumidification setup maintains the correct levels of moisture in a reefer. Keep in mind that different cargo needs different humidity levels.
Some shippers are known to stuff as much freight into the interior with no concern about proper airflow, putting the carrier at risk of maintaining proper temperature compliance which could result in a rejected load, a claim loss and a tarnished record with their customer.While the original design of truck trailer air chutes was static and prone to tears due to the end of the air chute hanging down into the cargo area, the newest air chutes are made of flexible material that allows them to automatically expand and contract (inflate or deflate) when the reefer unit is turned on and off. When the reefer is not in use, they stay out of the way for limited risk or damage. When the reefer is turned on, the air chute inflates and does its job.While air chutes reduce the negative impact of disadvantageous load organization on the cargo, the right load organization within the trailer is still essential.
Another feature you will come across when reviewing air chute designs is a ramped mesh material at the end of the chute that allows it to be fastened to the roof and still get good airflow performance to the rear of the trailer. It helps reduce the risk of snags from a forklift and/or freight during the loading and unloading process.
What does a chute do?
an inclined channel, as a trough, tube, or shaft, for conveying water, grain, coal, etc., to a lower level. a waterfall or steep descent, as in a river.
With an average value of approx. $60k in value, nobody wants to risk losing a cargo load because of inadequate air flow and elevated temperatures. Air chutes play a key role in truck trailers and truck transport when perishable or temperature-sensitive cargo is involved. Knowing the purpose of air chutes as well as their design and construction, helps shippers and carriers make the best decisions regarding their use in modern supply chain operations.
