OnlyKem Brand Commercial Refrigeration Condensing Unit for Fish


Commercial refrigeration condensing unit is the key component of cold room or blast freezer room which is commonly used for fish or fruit cold storage. The split units have limitations in terms of cooling capacity and redundancy functions, so that they can not meet the increasingly stringent requirements of the market. Commercial refrigeration condensing unit is a refrigeration unit composed of two or more compressors, which shares a set of parallel refrigeration circuit. The commercial refrigeration condensing unit is usually used in large cold storage projects, energy-saving and redundant.

At present, our commercial refrigeration condensing unit is more used for fish storage and quick freezing. Firstly, the treated fish is put into the blast freezer within 2 to 6 hours for quick freeze, then stored in the freezer room for a long term storage.

Fruit Cold Storage Room for Sale in Uzbekistan

Fruit Cold Storage Room is the widely used professional cold room to storage fruit or vegetable. Our successful installed fruit cold storage room further validates the vast refrigeration market in Uzbekistan, especially in fruit storage.

Fruit Cold Storage Room for Sale in Uzbekistan

Uzbekistan has a severe arid continental climate. Rainfall is concentrated in the eastern area. Winter is short and summer is hot and long. The average temperature in July is 26～32℃, the daytime temperature in the south is often as high as 40℃, the winter is short and cold, the average temperature in January is -6～-3℃, and the minimum temperature in the north is -38℃.


As the climate changes, people are most concerned about how to store the fruits, so how to keep the fruit fresh? For fruit planting industry and fruit sellers, the most important concern is the construction of fruit cold storage room. Let’s see how OnlyKem analyses it for our customers in Uzbekistan.


When building a fruit cold storage room, we must know that the preservation cold room is designed to inhibit the activity of microbes and enzymes, and to enable fruits to achieve a long-term preservation function.


The technique of keeping fresh in cold storage is to keep the stored fruit fresh at low temperature. Generally speaking, the temperature of the fruit should be limited to about 0 to 15 degrees. Keeping fresh and cold storage can effectively reduce the incidence of pathogenic bacteria, reduce the phenomenon of fruit decay.


It can also slow down the respiration and metabolism of fruits, thus preventing decay and prolonging the storage time of fruits, which is why we need to build fruit cold storage room. With the emergence of cooling machinery, it is possible to allow preservation techniques to be carried out after a phenomenon of rapid freezing, so that the quality of stored fruits can be preserved by a large margin.


When fruit cold storage room is built, polyurethane is generally used as material, and high pressure foaming technology can produce different length, different specifications of the insulation sandwich panel, so that the needs of different customers can be met.


Next, let’s show you the details of the project of OnlyKem fruit cold storage room in Uzbekistan.

Matters needing attention in fruit cold storage room
Check and maintain all equipment 1 month before fruit storage.
Thoroughly clean the walls, doors, floors and ceilings of the cold storage, and thoroughly disinfect the cold storage and fruit baskets before or after the storage.
3-5 days before storage to start cooling, so that the storage temperature in accordance with the storage temperature requirements.
The fruit should be pre-cooled before storage, and the storage temperature should be adjusted, especially the temperature of the fruit which is sensitive to the temperature.
The storage should be carried out in batches by stages, not too much at one time, the daily volume of storage can account for 1/5 /-1/10 of the storage capacity, otherwise, the heat brought into the field at one time is too much, the reservoir temperature is difficult to fall back, and the fluctuation is great.
Fruit by a certain form of stacking, stacking bottom to pad with stone or sleepers, and so on. The direction of the stack should be consistent with the direction of the wind in the storehouse.In order to make the air flow in the cold room, the stacking code should not be too crowded, the palletizing and wall palletizing should be kept about 1 meter. There should be about 80 cm between the top of the stack and the ceiling or ceiling duct, the distance between the stack and the evaporator should be kept at least 2 meters. The fruit close to the evaporator or tuyere is liable to freeze damage.
In the same cold room, it is best to store only one kind of fruit and try to avoid mixed storage of different properties.
