Code of practice during loading and unloading of refrigerated trucks


Different cargos have different requirements for the cabin temperature, but the temperature setting range in the specific transportation process needs to be determined according to the specific conditions of the cargo.

There are many considerations in the transport of refrigerated trucks. Once the cabin temperature is unstable during transportation and the cabin is too cold or too hot, the cargo cannot be stored for a long time and it is extremely easy to be damaged.

Truck refrigeration unit manufacturer Guchen Thermo said that in addition to paying attention to the transport process, loading and unloading goods cannot be sloppy.

Before loading
According to the temperature requirements of the transported cargo, the carriages are pre-cooled in advance until they reach the proper loading temperature.
If the humidity inside the box is heavy, the defrosting can be done manually or automatically. Generally, it can be controlled by a temperature controller.

When loading
Try not to open the door too much, reducing the entrance of hot gas and moisture.
Be careful not to obstruct the inlet and outlet of the evaporator when loading.
Cargo pallets are placed between the cargo and the carriage floor to ensure that the bottom cool air can circulate.

In addition, it is necessary to frequently check the chassis of the vehicle, the refrigeratedtruck unit, the backup power supply, etc. to ensure that it can work properly, so that it will not fail during transportation and cannot be moved, thus causing damage to the goods. At the same time, it is also necessary to clean the interior of the train frequently to ensure the safety of food transportation.

Guchen Thermo manufacture and supply all kinds of truck refrigeration units and van refrigeration units apply for small to big, large cooling capacity for long, middle or short distance frozen transport business.


For example the TR-300truck refrigeration units, it is front mounted vehicle engine driven units, especially apply for 10~20m³(L≤4.3m) small or medium sized refrigerated truck box. With the R404a Eco-friendly refrigerant, can make inner temperature keep at -20 to 25. So TR-300 small refrigerationunits for trucks are more suitable for transport frozen or deep frozen foods.

Problems to be aware of when using truck refrigeration units

It is generally believed that the goods with too high or too low temperature are loaded into the compartment of the refrigerated truck, and the truck refrigerating unit is set to the necessary transportation temperature. After a certain period of time, the temperature of the cargo will drop to or rise to its required temperature.

However, the opposite is true. China truck refrigeration direct drive manufacture said that not only does the temperature fall (or does not go up), the cargo damages or deteriorates. The cooling air blown by the truck refrigeration unit will change the temperature of the goods, and the water content of the goods will be lost. This will cause the quality of the goods to change, which will lead to a decline in the quality of the goods, a shortened storage period, and even a corruption of the goods.

Refrigerated cars are not cold storage. In the concept of many people, the truck refrigeration unit for ambient temperature on a refrigerated truck is free to freeze or heat the cargo loaded into the compartment to the necessary temperature. Good quality truck refrigeration unit manufacture Guchen Thermo said that truck chillers are used to maintain the temperature of the cargo, not to reduce the temperature of the cargo.

Truck refrigeration unit should be closed when loading and unloading. Many people do not shut down the truck chiller unit when loading or unloading goods, thinking that this can make the temperature of the goods rise more slowly. In fact, this is a very wrong understanding.

Clean the refrigerator compartment frequently. Truck refrigeration unit for ambient temperature manufacture Guchen Thermo said that the refrigerated trucks are often loaded with different goods, especially fish, meat, etc. It is best to clean the cars once after each shipment.

Prior to loading, the car must be pre-cooled or warmed up for about 1.5 hours. Good quality truck refrigeration unit manufacture Guchen Thermo said that when the cargo is loaded into the carriage, the ambient temperature inside the carriage will affect the temperature of the transported cargo, which will cause the quality of the transported goods to change. Therefore, the carriage must be pre-cooled to the necessary temperature before loading.


Guchen Thermo is the biggest truck refrigeration direct drive manufacture in China, we supply all kinds of truck refrigeration system, apply for small to big truck, direct drive, diesel powered and electric powered transport reefer units for your fresh, frozen or deep frozen transport.

Why Your Vehicle Refrigeration Units are not Refrigerating?

Some drivers may find that their vehicle refrigeration units have a better refrigerating effect at the first time when they buy it, but after works for a long time,maybe several months or 1 year, the transport refrigeration unit is not refrigerating well. So why this condition happened and how to solve it? Let’s see the detail reasons that may result in this bad refrigerating happening.

Bad air flow around the refrigerated truck body block the evaporator inlet
Airless is one of main reason that result in the “hot”. Usually, if there is something blocked in the evaporator inlet, then the cold air cannot blow evenly and result in the freezer in the roof of cargoes. 

In one hand, it also can result in the temperature increase in some part of truck body. In other hand, some of the vehicle refrigeration units have the defrost device, when the inlet is blocked, the 
transport refrigeration units evaporator pipe will be frozen quickly, and the vehicle refrigeration units will turn on the defrost device automatically, and then when the temperature is up to set temp, defrost device will end, and this circle will start again and again. And it will give the condition that the vehicle refrigeration units defrost frequently. 

How do you Solve the Vehicle Refrigeration Units not Refrigerating Problem? 


So in order to keep a better refrigerating effect, do not block the evaporator inlet, the cargoes should not pack too high to block the inlet. When upload cargoes, leave at least 225mm height between the roof of cargo and the roof of truck body, and cargo height is not higher than evaporator inlet height. 

Besides that, keep the truck body clean, do not leave paper scrap or packing paper, because the
 refrigeration units for trucks evaporator fans will intake the paper or scrap, then lots of dust will attached to the evaporator pipe, decrease the heat exchange rate, and the refrigerating system will not work well. 

How to Use Truck Refrigeration System Transport Cargo Better?

In order to keep the frozen foods fresh and decrease the food damage, it needs to be in the low temperature all the time after it manufactures, transports and delivers to customers. So how to make your truck refrigeration system in a proper situation and finish this frozen transport ideally? Let’s see this article to get more tips! 
1.Cooperate the truck refrigeration system properly 
The 
truck refrigeration is one of the most important equipment in a reefer truck, so to know how to cooperate the truck refrigeration unit rightly is the key to keep frozen cargoes safe, especially for the long distance transport refrigeration unit, drivers need to pay more attention to the truck refrigeration and transportation. 
2.Preventive maintenance of the truck refrigeration system and trucks 
Preventive maintenance can decrease the repair and cooperation cost and increase the 
truck refrigeration working life. Usually, the truck engine needs to be maintained after 10000km, and the truck refrigeration system needs to be maintained after 500-700 hours working. Take Guchen Thermo truck refrigeration system as example, after 500-700h working hours, it need to be oil filter, fuel filter and air filter; check the belt and whether refrigeration system leakage.
3.Suitable package is the key to protect frozen cargoes
For the frozen cargoes, it needs airless package, and for the fresh cargoes, it needs ventilated package. What’s more, all the package needs to be pressure proof. 
4.Precool or preheat before upload frozen cargoes
Before upload the frozen cargoes, please turn on the
 truck refrigeration system and set the required temperature, precool or preheat for 1.5 hours, and then turn off the truck refrigeration, upload cargoes fast. 

Tip: Why Precool or Preheat is Important When Upload Frozen Cargoes? 
5.Check the cargoes temperature when cargoes are uploaded in the refrigerated trucks 
It seems that there is a common mistake that most people may make, people always think that the 
truck refrigeration system can decrease or increase the cargoes temperature to the required temperature. In fact, the truck refrigeration is used to keep the cargoes temperature not decrease or increase cargoes temperature. 

Tips: Why Needs to Turn off Truck Refrigeration System When Upload Cargoes? 

6.Do not put the cargoes in the truck refrigeration evaporator inlet

Usually, the airless in the refrigerated truck body is main reason that result in cargoes damage, in fact, any block materials around cargoes may result in “hot”. So when upload cargoes, carefully check whether the cargoes block the truck refrigeration evaporator inlet. Keep the cargoes height is lower than truck refrigeration evaporator inlet height. If not, it will effect the temperature and even effect the truck refrigeration system working.

Tips: 
Why Your Truck Refrigeration System is not Refrigerating? 
7.Keep the refrigerated truck body clean
Clean the truck body, and do not leave packing paper or paper scrap in truck, because it will block air flow or intake by evaporator, then effect the refrigerating system. For long time, the more impurity will be attached to the evaporator tube, and decrease the heat exchange rate. That is why some drivers think that their
 truck refrigeration units not refrigerating better than before. 

To conclusion, keep the perishable food fresh and high quality is the main purpose of frozen food transportation, and keep low temperature condition is core, so it needs more attention and investment. So the first step for the truck drivers is use 
vehicle refrigeration system correctly and it is also the key point to keep cargoes quality.  
Guchen Thermo as the truck refrigeration manufacturers in China, not only sell our transport refrigeration units, but also glad to share more refrigerated transport smart tips and industry news to help more people knowing cold chain transportation better.

Why Needs to Turn off Truck Refrigeration Unit When Upload Cargoes?

Some smart tips that drivers should to know when they cooperate the truck refrigeration unit during the frozen transport business, for example, turn off the truck reefer unit when upload the cargoes, let’s see why should do this.

It’s know to us all that before upload cargoes, it needs to be precool or preheat for 1.5 hours in order to keep the cargoes fresh, but few people to know it should turn off the
refrigeration units for trucks when upload the cargoes. So why should do this? 

Reason: when after precool truck body to the required temperature, if the 
truck refrigeration unit is still on, and the evaporator fans are still working, the front side is positive pressure and the back side is negative pressure, so the cold air will blow from the roof of truck body, and intake much hot air into the down side of truck body, which result in the temperature is up quickly; if turn off the refrigeration units for trucks, and then upload cargoes, evaporator fans are not working, and air flow stops, the pressure is same between outside and inside of the truck body, so the outside hot air is intaken into the truck body slowly. 

Do you get this smart tip? Come to use this tip when you use the truck refrigeration unit next time!
