Refrigerators of the Belarusian brand have been occupying leading positions in the market of the post-Soviet space for many years. Buyers are attracted by the affordable price, reliable assembly and maintainability of the equipment. However, if the main unit breaks down, the owner is faced with the question: who makes compressors for Atlant refrigerators and whether it is possible to replace the original part with an analogue from another manufacturer.
The answer to this question is not as simple as it might seem at first glance. Over many years of production, the manufacturer collaborated with various suppliers, changing logistics and technical solutions depending on the economic situation and the availability of components. Understanding whose motor is installed in your device is critical for correct refrigerator repair.
In this article we will take a detailed look at all the main suppliers, learn to distinguish them by appearance and markings, and also consider the features of replacement and operation. You will find out why the same plant in Minsk can have units that are completely different in design and characteristics.
History of suppliers and the current situation
At the beginning of the journey, when mass production of modern models was just starting, the Minsk plant actively purchased components abroad. For a long time, sealed units from the German concern Secop (formerly Danfoss) were considered the standard. They were famous for their quiet operation and high reliability, which created a reputation for a quality product for the brand.
However, geopolitical changes and logistical gaps among manufacturers have reconsidered supply chains. The plant began to actively implement its own developments and purchase components from partners from Asian countries. Today, in one model range there can be different designs, which sometimes confuses even experienced craftsmen.
It is important to understand that The main and full-time supplier today is our own compressor plant located in Bobruisk. This allows you to control costs and guarantee the availability of spare parts on the market. However, old models produced 10-15 years ago were often equipped with imported components.
Own production: Bobruisk plant
Bobruisk plant "Atlant" is a city-forming enterprise that specializes exclusively in the production of hermetic compressors. It is these units that you will find in the vast majority of modern refrigerators sold in stores. They are marked with the Atlant logo and have a characteristic black or gray cylindrical body.
Technically, these devices are of the crank-yoke type. They are less noisy than piston counterparts of older generations and have a good service life. To start them, start-up relays are often used, which are easy to find on sale. The design is as unified as possible, which simplifies replacement of the compressor in the event of failure.
A feature of Bobruisk motors is their adaptability to domestic operating conditions. They are better able to withstand voltage changes in the network and are less demanding on the quality of the refrigerant. However, it is worth noting that their noise level may be higher than that of premium European analogues.
A special brand of oil is used inside the housing, which is not recommended to be mixed with compounds from other manufacturers. When carrying out work to replace the unit, it is necessary to strictly adhere to the technology of vacuuming the system to avoid moisture ingress.
German heritage: Secop and Danfoss
If you own a refrigerator manufactured between 2000 and 2015, there is a high probability that a unit from the company is installed inside. Secop. Previously, this business segment belonged to the Danish-German giant Danfoss, and this name can be found on the nameplates of old models.
These compressors are considered the standard of reliability in their class. They are characterized by very low vibration levels and energy efficiency. Visually, they are easily recognized by their characteristic elongated shape and the often found green or black label with technical data. Many craftsmen are still looking for them to replace them on older models.
⚠️ Attention: When trying to replace an old Secop with a modern analogue, be sure to check the installation dimensions and type of refrigerant. Direct replacement is not always possible without modifying the copper tubes.
The main problem today is that it is almost impossible to find a new original Secop unit; the market is filled with refurbished versions or fakes. Therefore, in the event of a serious breakdown, it is often more rational to consider installing a high-quality analogue from another manufacturer than to look for a “native” unit from scratch.
Other manufacturers and analogues
In addition to our own and German units, in Atlant refrigerators you can find products from other world brands. The plant purchased them in batches at different periods of time, so their presence cannot be ruled out. Most often, you can find compressors from a Brazilian company Embraco or an Italian one Aspera (which is also part of the Embraco holding).
These devices have proven themselves to be powerful and durable. They were often installed in large volume two-compressor models. Their design is slightly different from the Bobruisk ones, which requires a careful approach during installation. In particular, the diameters of the fittings for connecting the tubes may differ.
Also in older models (90s) there were units from LG or Samsung, but replacing them with modern analogues requires a qualified approach. Differences in the electrical characteristics of the starting winding can lead to rapid failure of the new motor or starting relay.
Is it possible to install a compressor from another brand?
Theoretically, it is possible if the power, type of refrigerant (R134a or R600a) and overall dimensions match. However, replacement requires alteration of the pipelines and electrical circuit. It is better to use standard solutions.
How to determine the model and manufacturer
Before ordering a spare part or calling a technician, you must accurately identify the installed equipment. All the necessary information is contained on the factory tag, which is glued to the metal body of the compressor itself. You can get to it by removing the rear protective cover of the refrigerator.
The nameplate indicates the type of refrigerant, operating voltage, current and, most importantly, the model. The first letters or numbers of the code can often determine the origin. For example, models starting with CT or C often refer to the Bobruisk line, while NL or BD may indicate Secop/Danfoss.
For accurate decoding it is better to use correspondence table or refer to the refrigerator documentation. Below is a summary of the main features:
| Manufacturer | Characteristic features | Refrigerant type | Status |
|---|---|---|---|
| Atlant (Bobruisk) | Atlant logo, gray/black body | R134a / R600a | Main supplier |
| Secop (Danfoss) | Green/black sticker, elongated shape | R134a / R600a | Old models |
| Embraco / Aspera | Silver or black body, compactness | R134a / R600a | Rarely |
| LG / Samsung | Specific shape, often aluminum tubes | R134a | Very old models |
Please note that the type of refrigerant is a critical parameter. Replacing the compressor under R134a to a unit running R600a (isobutane) is strictly prohibited without a complete rework of the system, since they use different types of oils and have different operating pressures.
Fault symptoms and diagnostics
You can understand that the compressor has failed according to a number of indirect signs. The most obvious is that the refrigerator has stopped freezing, but the light inside is on. The motor may either not start at all, or turn on for a few seconds and immediately turn off with a characteristic click.
Another alarming signal is the appearance of extraneous sounds. A loud knock, clanging or metallic grinding sound indicates mechanical destruction of internal components. In such a situation, it is impossible to operate the equipment, since the products of metal destruction will enter the pipe system and filter, which will make repairs economically unfeasible.
☑️ Primary diagnostics of the compressor
If the motor hums but does not start, the problem may not be in the compressor itself, but in the start relay or a broken winding. In some cases, replacing the relay helps, which costs much less than buying a new unit. However, diagnostics must be carried out by a specialist using a tester.
Features of replacement and repair
Replacing a compressor is a complex technological process that requires special equipment. You will need a vacuum pump, a gauge station, a torch and a set of tools for rolling copper tubes. Simply “unscrewing and screwing” will not work here.
The process begins with pumping out the old refrigerant and dismantling the old unit. Then the new unit is sealed, the filter-drier is necessarily changed (this is a mandatory rule!). After assembling the circuit, the system is evacuated for 15-20 minutes to remove moisture and air.
⚠️ Attention: Never replace the compressor without evacuating the system. The remaining moisture will freeze in the capillary and block the circulation of freon after a few days of operation.
The final stage is to fill the system with refrigerant strictly according to the weight indicated on the refrigerator nameplate. A lack or excess of freon will lead to incorrect operation and overload of the motor. After refueling, all connections are checked for leaks with a soap solution.
Questions and answers (FAQ)
Is it possible to replace the compressor on an Atlant refrigerator yourself?
Theoretically, it is possible if you have the skills to solder copper pipes, a tool for vacuuming and knowledge of electrical engineering. However, without professional equipment (a vacuum pump and refueling scales), it is impossible to do the job efficiently. Handicraft repairs often lead to repeated breakdowns after a month.
Why does the new Atlant compressor get hotter than the old one?
Modern units often operate at higher housing temperatures due to the use of new types of refrigerants and optimization of heat transfer. If the temperature does not exceed 80-90 degrees and the refrigerator freezes, this is normal operation. You should sound the alarm if the motor gets red hot or smells of burnt insulation.
How long does the compressor last in Atlant refrigerators?
The average service life of a standard Bobruisk compressor is 7-10 years under normal operating conditions. Imported analogues (Secop) can work for 12-15 years or more. The service life directly depends on the stability of the voltage in the network and the regularity of defrosting.
What is the difference between a compressor for R134a and R600a?
They differ in operating pressure, type of oil used and the diameter of the fittings. Refrigerant R600a (isobutane) is explosive, so the tightness and quality of soldering when using it is even higher. It is impossible to change one type to another without recalculating the entire system.
