The question about the origin of the main unit of the cooling system often arises among owners of household appliances when the standard operating mode is disrupted or an urgent replacement of a part is required. For Russian brand equipment Biryusa this question is especially relevant, since the company has collaborated with many different manufacturing plants around the world over many years of production. Understanding who exactly produced the one installed in your compressoris critically important for the correct selection of an analogue and successful repair.
Logistics chains and the economic situation directly influenced the choice of suppliers for the Krasnoyarsk plant. At different periods of time, one could find markings of European giants on the units, such as Danfoss or Secop, as well as more affordable models from Chinese or Belarusian manufacturers. That is why there is no universal answer for all models - it is necessary to carry out individual diagnostics of a specific instance.
In this article we will look in detail at how to identify the engine manufacturer by external features and the factory sticker, what technical nuances are typical for different brands and what to look for when ordering spare parts. Accurate knowledge of the unit model will allow you to avoid compatibility errors and extend the life of your refrigerator.
History of suppliers and change of plant partners
The Biryusa plant, located in Krasnoyarsk, has a rich history dating back to the Soviet period, when the enterprise was called KZH (Krasnoyarsk Refrigerator Plant). In those days, the main supplier of units was a plant in the city Murom, which produced compressors of the FK i DHseries. These motors were famous for their maintainability and simplicity of design, although they were inferior to modern analogues in energy efficiency.
With the collapse of the USSR and the opening of markets in the 90s and early 2000s The plant began active cooperation with European companies. Danish compressors became the gold standard for many middle- and high-class models. They were distinguished by high reliability and low noise levels, which became a key advantage for the marketing of Biryusa refrigerators. Danfoss, which later changed owner and began to be produced under the brand Secop. They were distinguished by high reliability and low noise levels, which became a key advantage for the marketing of Biryusa refrigerators.
In recent decades, due to optimization and changes in logistics, the manufacturer began to introduce units of other brands into assembly lines. In particular, compressors Embraco (often assembled in factories in Europe or China) and Belarusian motors Atlanthave become widespread. There are also models from Chinese manufacturers, such as Jiaxipera or Donper, which are installed in budget series.
⚠️ Attention: The equipment of refrigerators may change depending on the release date of the batch. Even within the same model (for example Biryusa 133), completely different compressors could be installed in different years. Always rely on the markings on the nameplate of your device, and not on reviews on the Internet about the same models.
Understanding these dynamics helps to understand why different “hearts” can be hidden in the same case. If you are planning to purchase used equipment or spare parts, the year of manufacture becomes the second most important factor after a visual inspection.
How to identify the manufacturer by marking
The most reliable way to find out whose compressor is in your refrigerator is a visual inspection of the metal tag attached to the motor housing. It is usually located on the top or side of the unit and contains a barcode, serial number and manufacturer's logo. However, over time, the label may become dirty, faded, or partially destroyed by corrosion, which requires careful examination of the remaining symbols.
Pay attention to the alphanumeric model code. Different manufacturers have their own coding systems. For example, Danish Danfoss and Secop models often begin with the letters NL, BD or TL, followed by a digital designation of the cylinder volume. Belarusian compressors Atlant have their own specific markings, often containing the factory abbreviation or characteristic prefixes.
If the sticker is unreadable, you can try to identify the manufacturer by the characteristic appearance of the casing and the location of the pipes. European units often have a more compact, “squat” body, while some Chinese counterparts can be elongated in height. It is also worth inspecting the electrical connector: it often has a specific shape that differs from standard connectors. Danfoss it often has a specific shape that differs from standard connectors Embraco.
If the marking is completely unreadable, all that remains is expert method: measuring current consumption and comparing cooling capacity with tabular data, but this requires special equipment and skills of a specialist.
Review of the main manufacturers of compressors
Let us analyze in detail the characteristics of the most common brands that can be found inside Biryusa refrigerators. This knowledge will help you evaluate the quality of the installed equipment and choose the right replacement.
Danfoss / Secop
For a long time they were considered the standard of reliability. Units of this brand are characterized by low levels of vibration and noise. Structurally, they are often made in the form of a sealed block, where the motor and compressor part are located in a single casing. An important feature is high sensitivity to refrigerant quality and system cleanliness. When replacing such motors, thorough vacuumization is required.
Embraco
Brazilian brand, whose factories are scattered around the world (Italy, China, Slovakia). Compressors Embraco are famous for their energy efficiency and durability. In Biryusa refrigerators they were often found in models in the mid-price segment. They have a robust design and can withstand voltage surges well, which is important for Russian power grids.
Atlant (Belarus)
Budget and reliable solution. Compressors from the Minsk plant are often used both as standard ones and as replacements during repairs. They can work a little louder than their European counterparts, but are distinguished by high maintainability and availability of spare parts (start-up relays, capacitors).
Chinese manufacturers (Donper, Jiaxipera, LG (China))
Modern Chinese compressors have significantly surpassed the stereotypes of low quality. Models from Donper or Jiaxipera are often copies of proven European drawings. They are compact and efficient, however, when choosing an analogue for replacement, it is important to accurately determine the power and type of refrigerant.
The myth about the “original” compressors
There is an opinion that the Biryusa plant produces compressors itself. This is wrong. The plant assembles refrigerated cabinets, and motors are purchased from specialized manufacturers. Therefore, it is pointless to look for a “native Biryus compressor” - you need to look for the brand that is indicated on the nameplate.
Technical characteristics and compatibility
When selecting a replacement unit, it is not enough to know only the brand. The coincidence of a number of technical parameters is critically important. An incorrectly selected compressor can lead to rapid failure of the entire system, overheating or insufficient cooling.
First of all, pay attention to the type used refrigerant. Old Biryusa models worked on R12 (freon-12), newer ones - on R134a, and modern environmentally friendly models use R600a (isobutane). Compressors for different freons have different oil and electrical design; their interchange without reworking the system is impossible.
The second important parameter is the power and cylinder volume. They must match the volume of the refrigerator and freezer compartments. Using a weaker motor will cause it to run non-stop trying to get up to temperature, which will quickly burn it out. Too powerful a motor will cause frequent switching on/off (clocking), which is also harmful.
Also consider the type of start: RSIR (resistive start), RSCR (with a starting capacitor) or inverter. The start-up protection relay must strictly correspond to the type of compressor.
POE (synthetic) or Mineral
| Parameter | Description | Where to find |
|---|---|---|
| Model | Manufacturer's article number (e.g. NL9G) | Metal tag on the body |
| Refrigerant | Gas type (R134a, R600a) | Compressor tag and sticker inside the cabinet |
| Power | Watts (W) or HP | Technical documentation or tag |
| Voltage | 220-240V / 50Hz | Electrical diagram or tag |
| Oil type | Depends on the type of freon (R134a/R600a - POE) |
⚠️ Attention: Changing the type of refrigerant (for example, switching from R12 to R134a) requires a complete flush of the system, replacement of the filter drier and often replacement of the evaporator. This is a complex procedure that cannot be performed efficiently at home without a vacuum pump and a pressure gauge station.
Typical faults and diagnostics
Understanding which compressor is installed helps to quickly diagnose the problem. For example, Danfoss is characterized by specific breakdowns of the valve group when moisture gets in, and for budget Chinese models - failure of the windings during voltage surges.
The first sign of a malfunction is often a change in the nature of the operation. If the engine hums but does not start, or starts for a few seconds and clicks, most likely the problem is starting relay or jamming of the piston group. If the compressor works constantly, but does not cool, there may be a freon leak or loss of compressor performance.
Checking the integrity of the windings can be done with a multimeter. It is necessary to ring three contacts: general, starting and working. The resistance between them must be within certain limits (usually from 10 to 50 Ohms). If the multimeter shows an open circuit or short circuit (0 Ohm), the compressor must be replaced.
☑️ Diagnostics before replacement
Do not forget about the thermal protection relay. If it works too often, the compressor may overheat due to poor ventilation or contamination of the condenser at the back of the refrigerator.
Replacement process and recommendations of technicians
Replacing the compressor in the Biryusa refrigerator is a complex technical process that requires special equipment. It includes unsoldering old pipes, installing a new unit, evacuation of the system and charging with refrigerant.
To carry out the work, you will need a burner (gas or oxygen-acetylene), a set for rolling pipes, a vacuum pump, a pressure gauge station and scales for precise dosing of freon. You cannot simply “solder” a new motor without vacuuming - the remaining moisture and air will destroy the system in a few months.
When installing, it is important to choose the right analogue. If the original compressor Danfoss cannot be found or is too expensive, you can install a universal analogue from Atlant or Embraco. The main thing is the coincidence of overall dimensions (to fit into the casing) and mounting feet.
After installing the new unit, be sure to replace filter-drier. This is a disposable element that collects moisture and oil breakdown products. Installing an old filter will negate all repair efforts.
Repair cost and feasibility
When deciding on repairs, it is worth considering economic feasibility. The compressor is the most expensive part of the refrigerator. The cost of a new unit from a well-known brand (Danfoss, Embraco) can be a significant part of the price of a new budget refrigerator.
To the price of the compressor itself, you must add the cost of the work of a specialist, travel, consumables (freon, oil, filter, solder). As a result, replacing the motor in a service center can cost 50-70% of the cost of a new device of the same class.
However, if the Biryusa refrigerator is an old, time-tested model with a high-quality internal coating of the chambers and working automation, replacing the compressor can extend its life by another 5-7 years, which is economically justified compared to buying new equipment with unpredictable resource.
Is it worth exchanging for a used one?
Buying a used compressor from disassembly is a lottery. The service life of the motor is unknown; it could work for 10 years, or it could work for 1 month. Saving 30% is not worth the risk of repeat repairs in six months. It is better to buy a new, albeit less famous brand.
Frequently asked questions (FAQ)
Is it possible to put Atlant in a Biryusa refrigerator with a Danfoss compressor?
Yes, this is possible, but it requires a professional approach. It is necessary to select an Atlanta model with similar cooling capacity and overall dimensions. It may also be necessary to replace the start relay and adjust the copper tubes, since the diameters of the pipes may differ.
Why is the compressor humming in the Biryusa refrigerator?
The humming can be caused by several reasons: wear of the motor bearings, imbalance, resonance of the tubes or housing, as well as problems with the electrical part (humming transformer or relay). If the humming noise appears sharply and is accompanied by vibration, most likely the problem is mechanical.
Where can I find the compressor code if there is no sticker?
If the sticker on the compressor itself is lost, try to find the information on the general service sticker inside the refrigerator compartment (usually on the side wall or ceiling). The equipment code may be indicated there. Also, the motor model is sometimes written with a marker on the casing itself during factory assembly.
How long does the compressor last in the Biryusa refrigerator?
The average service life of modern compressors is 10-15 years. European models (Danfoss, Secop) under favorable conditions can work for 20 years or more. Chinese and budget models are usually designed for 7-10 years of active use.
