How Long Does It Take A Reefer To Cool Down
The fact that you are reading this indicates you are a trucker, shipper, or someone in the industry who would like to understand more about reefer containers, aren’t you?
Reefers, short for refrigerated containers, have become essential for transporting perishable items like food and medicines around the world.
And the most important thing in the transport business is to make sure that your cargo is kept in the right temperature range.
After all, time is money, and not knowing when a reefer is ready can create some costly delays in your supply chain.
So the old age question remains: how long does it take for a reefer container to cool down?
Maybe two to three hours or even more?
Let’s take a look at some facts to get an idea.
How Long Does It Take A Reefer To Cool Down
Well, just like most things in life, the answer isn’t a one-size-fits-all deal.
But lemme give you a general breakdown.
But don’t be fooled; the answer isn’t that straightforward. Let’s explore this in a bit more detail.

Factors That Influence The Cooling Rate Of A Reefer
Now that we have a general idea of a reefer’s cooling time let’s look at some factors that can influence the cooling rate.
These are:
1. The size of the container:
The size of the reefer plays a big role in the cooling process.
Larger reefers have more volume inside, so they must work harder to decrease the temperature. As such, it will typically take a larger reefer longer to cool down than a smaller one.
2. The temperature of the reefer:
Another factor to consider is the starting temperature of the reefer.
If you’re starting with a hot truck, it’s surely going to take longer for it to cool down than if you had started with a truck already at a cool temperature.
3. Refrigeration Unit:
The type of refrigeration unit being used can also impact the cooling process.
Some units are more efficient than others, which means they may be able to bring the temperature down more quickly.
4. Ambient Temperature:
Last but not least, the temperature outside the reefer also affects the rate at which it cools down. If it is hot and humid outside, it will take longer to cool the inside of the container.
On the other hand, if it’s a relatively cool day, the cooling process may be a bit faster.
How Can You Reduce The Cooling Time Of The Reefer?
In the world of shipping and transport, time is of the essence, and you want to make sure your cargo gets there on time.
So, how can you reduce the cooling time?
Here are some tips that can help you reduce the cooling time of the reefer.
1. Pre-Cooling:
One of the most effective ways to reduce cooling time is pre-cooling your reefer.
This means reducing the temperature of the reefer before loading it with cargo, which ultimately can help reduce cooling time when the doors are closed.
2. Use The Right Refrigeration Unit:
Using the right refrigeration unit can also help reduce cooling time.
Look for a unit designed to maximize efficiency, which can help lower the temperature quicker.
3. Insulate The Container Well:
Insulating the container is another thing you can do to reduce the cooling time of the reefer.
This is because insulation helps keep the temperature stable, which can decrease time spent cooling down.
Literally, every second counts in the shipping and transport industry.
Use these tips to reduce the cooling time of your reefer and make sure that your cargo is kept in the right temperature range.
Pro Tip: Consider using a hybrid reefer solution for the best results. A hybrid reefer combines traditional diesel and electric power, which can help reduce fuel consumption and emissions while still providing the necessary cooling performance.
What Temp Should A Reefer Be Set At?
Well, there is no hard fast answer to this question, as the optimal temperature will depend on the type of cargo being shipped.
But, the ideal temperature for most products is between 0 and -25 degrees Celsius.
Please remember that this is merely an estimate, as certain products may require different temperatures.
Pro tip: To make sure that your cargo is transported and stored in optimal conditions, you should always consult the manufacturer before setting any temperatures.
How Often Should You Check The Reefer Temperature?
Again, this will depend on the type of cargo being shipped.
But, generally speaking, you should check the temperature of your reefer at least twice a day.
Medical and pharmaceutical products, for example, may require more frequent checks.
Not doing frequent temperature checks can lead to spoilage and other issues, so you must be diligent about checking the temperature.
After all, it’s better to be safe than sorry.
How Long Can A Reefer Container Be Unplugged?
Sometimes, you may face a situation where you will need to unplug your reefer for a while due to unavoidable circumstances.
However, how long can a reefer container be unplugged without being damaged?
Well, a reefer container can be unplugged for up to 6 hours without any significant temperature change.
So how does the reefer maintain its temperature during this time?
The answer is pretty simple – Reefer containers are designed with a thermal insulation system that helps keep the temperature inside the container steady.
However, if the reefer is unplugged for more than 6 hours, the temperature can increase significantly.
So, it’s important to make sure that the reefer is plugged in at all times.
At the end of the day, it pays to take extra precautions when using reefer containers – because time is of the essence in shipping and transport.
Wrapping Up
So, there you have it – a comprehensive overview of reefer containers and how to reduce their cooling time.
Reefer containers are becoming increasingly popular in the shipping and transport industry every passing day, especially when transporting temperature-sensitive products.
It can take anywhere between two to three hours to cool down a reefer container, depending on various factors.
Trust me; these tips can help you save time and money, so implement them if you use reefers for shipping and transport.
Frequently Asked Questions
Q: How cold do reefers get?
A: Reefers can reach temperatures as low as 0°F (-18°C) and even more, depending on the type of cargo and the conditions. Temperature control is achieved by using a reefer container’s cooling system, which utilizes air or liquid to achieve the desired temperature.
Q: Is it safe to transport food in a reefer container?
A: Yes, reefers are designed specifically for transporting temperature-sensitive products. They provide an optimal environment for storing and transporting food products safely.
Q: Do reefer containers have ventilation?
A: Yes, reefers typically come with an exhaust system that helps equalize the air pressure and reduce condensation. This helps to protect the cargo from moisture damage.
