"Freezing cabinet simple introduction
Relative to the ordinary box, the freezer in addition to the box wrapped in the internal insulation with insulation (commonly known as foam layer) in addition to some special equipment.
In order to facilitate your daily use, here we have marked the key parts of the freezer for your reference.
Unit display board
Refrigeration lamp: when the refrigeration compressor is turned on, the lamp is turned on.
Heating lamp: when the unit is in the heating or defrosting mode, the lamp turns on, indicating the working status of the heater.
Defrost lamp: when the unit is in defrost mode, the lamp turns on.
In Range Lamp: The lamp turns on when the control temperature sensor is within the permissible error of the specified set point.
Air Out Light: This light turns on when the air out thermostat is being used for control. When this light is on, the temperature shown in the air temperature display is the reading at the return air thermostat. This display will flash if the dehumidification or humidification function is activated.
RETURN AIR LIGHT: This light turns on when the return air thermostat is used for control. When this light is on, the temperature shown in the air temperature display is the reading at the return air thermostat. This light will flash if the dehumidification or humidification function is activated.
Alarms: This light turns on when there is a valid or invalid shutdown alarm in the alarm queue.

Summary of common problems in the use of freezing cabinet
Firstly, for the import aspect. Due to the requirements of the Commodity Inspection Bureau, when you are importing goods as fruits, you need to provide the cold treatment records of the goods.
Secondly, for the export aspect here also collated some common problems when you use the box in daily life for your reference:
1. Please make sure to load the goods reasonably, if you overload the goods into the box, the maximum load height should not exceed the red load line of the container. Otherwise, it will affect the cold air circulation inside the freezer container, causing poor wind circulation leading to poor insulation effect or even failure of the freezer.
When the freezer container is loaded, the goods must be placed up to the edge of the T-floor. This ensures even air circulation throughout the container. If there is not enough cargo to fill the T-floor, it is recommended to fill the empty spaces with padding or cushioning. This method can also be used to fill gaps in the centre panel between pallets. By following the guidelines below, you can ensure that the air in your freezer container circulates around the merchandise in the route you want it to, rather than bypassing the entire load. (Separate picture attached for reference)
2. the temperature of the goods themselves should be the same as the set temperature to avoid possible damage to the goods caused by hot loading situations.
3. please don't start the freezer equipment when you open the door of the box, such as refrigeration of the freezer when the door of the box is open, it is easy to make the moisture in the air coalesce on the condenser coil, which leads to serious frosting of the condenser coil, resulting in non-refrigeration phenomenon of the freezer.
4. If you send the box to the factory for loading, please ensure the quality of the sockets used and the stability of the voltage, to avoid damage to the relevant parts of the container caused by unstable voltage or due to irregularities in the sockets.
5. The goods need to be pre-cooled before shipping and then loaded into the container. to achieve the optimum temperature level, which will reduce the effect of external temperature on the product during transport. To maximise the shelf life of the goods.
6. The items used to package the goods need to be moisture resistant.
Is a dry freezer a dry cabinet OR a freezer? What should I pay attention to?
Cabin space has been confirmed, but there is no container to lift. The shipping company tells you that you can pick up the container directly if you use a dry or frozen container ...... To pick up or not to pick up?
What is dry freezer?
Dry freezer means cold instead of dry, the freezer is used as an ordinary cabinet to load ordinary goods, without running the freezing equipment. English abbreviation for NOR, that is, Non Operating Reefer, said cold dry container.
The significance of the existence of dry freezer
China's import and export there are a variety of surpluses and deficits, the cargo structure is extremely complex, if you want to go to the port of destination is currently in urgent need of a large number of frozen containers, the port of departure, but the frozen containers are piled up, but at the same time the shipping company does not want to transfer the empty container to increase the cost of transferring the box, in order to alleviate the contradiction, the shipping company will dismantle the refrigeration compressor of the refrigerating container, the owner of the cargo using the refrigerating container to ship, which is called the frozen instead of the dry, the shipping company's move is in order to make better use of boxes! Improve the turnover rate of heavy cargo.
The difference between dry freezer and dry container
The volume of freeze-dry container is slightly smaller with the same container
The volume of dry container of the same container type is larger
Shorter container-free period and stacking-free period
Longer container-free and stack-free periods
Individual countries have restrictions on lyophilised cabinets
Generally no restrictions
Shipping companies encourage the use of freeze-dried containers, low freight rates
High freight cost
Precautions for the use of dry freezer
1.NOR (dry freezer) need special application, not just want to use it, generally spring and summer export to South America, Australia and New Zealand and other directions, the shipping company will allow NOR!
2. Dry freezer is really cheap, but not all the goods are suitable for applying NOR, due to the refrigeration equipment, so it is not suitable for loading too heavy, the goods and dangerous chemicals, so as not to damage the cabinet.
3. Very hard goods are also not suitable for NOR, even if not very hard, the goods need to be soft-packed, so as not to damage the internal insulation layer of the box.
4. Freezer before the general transport of meat, fruits and vegetables and other fresh goods, there will be residual taste. And clothing, silk or some other easily affected by the smell of the goods are not suitable for such container transport.
5. The freezer itself has a special setup inside, forklift loading containers should pay attention to avoid not being able to enter or destroy the box.
6. The rent-free period of dry and frozen containers is relatively short, taking into account the factory scheduling and delivery of articulation problems, choose NOR with caution.

(Container dimensions are for reference only, actual measurement shall prevail)
The actual freeze instead of dry operation, because the freezer air-conditioning and internal insulation layer accounted for space, for insurance purposes, generally the same type of cabinet than according to the ordinary container shrinkage of a certain volume to calculate the goods.
In short, dry freezer in freight because of the shipping company's incentives will be more favourable than the general container, but taking into account the actual operation of the problem, be careful to choose dry freezer."
