When an old refrigerator finally breaks down or is sent for recycling, the owner is often faced with the question of the value of its internal components. Compressor is the heart of the unit, and it is this that is of greatest interest to the secondary market and metal collection points. However, the cost of this part may vary depending on many factors, from current quotes for non-ferrous metals to the condition of the unit itself.
Many people mistakenly believe that the engine can be profitably sold as a working unit for repair, but the reality is that the lion's share of compressors is recycled. Hermetic compressors old models contain a significant amount of copper in windings and steel in the casing, which determines their liquidity. Understanding the price structure will help you not to undercut the price when handing over or, conversely, not to waste time looking for a buyer where there is none.
In this article we will analyze in detail what the cost of an engine consists of, how to extract it correctly to obtain maximum profit and what nuances of valuation exist. The average price per kilogram of copper-containing scrap in 2026 ranges from 350–450 rubles, but the net yield of metal from the compressor is only about 10-15% of its total weight. Let's look at all aspects more details.
Factors influencing the cost of the compressor
The first thing you need to understand: the price is formed not by appearance, but by internal content. The main cost driver is availability non-ferrous metals, in particular copper. The more copper there is in the stator windings, the higher the final amount will be when scrapped. However, there are other parameters that buyers of scrap take into account when accepting.
The second important aspect is the dimensions and weight of the device. Old Soviet models, such as DH-K or FY-100, are distinguished by a massive body and a thick layer of steel, but may have a lower copper yield compared to more modern analogues. The weight of the compressor directly affects logistics: if you deliver one piece, delivery can “eat up” all the profit, so it is important to evaluate profitability.
⚠️ Attention: The cost of non-ferrous metal scrap is a floating value. It depends on LME stock quotes and the internal policies of a particular collection point. Before your trip, be sure to check the current price list with the receptionist, as prices may change weekly.
It is also worth considering the condition of the case. If the engine has severe mechanical damage, traces of opening or corrosion, it may be accepted under a lower category or with a blockage coefficient. Integrity is important even for scrap, as it simplifies sorting and recycling.
Sell as a used spare part: is there demand?
Trying to sell an engine as a working spare part is a risky and often futile path. The fact is that hermetic compressors they are not intended for repair at home. If an old unit burns out or loses performance, it is almost impossible to restore it without special factory equipment for soldering and vacuuming.
Demand for used compressors exists only in narrow niches. For example, craftsmen may be looking for rare models to replace retro refrigerators, where it is important to preserve the original appearance and dimensions of the unit. They also sometimes look for engines for conversion into compressors for inflating tires or airbrushing, but for these purposes they often buy new specialized units.
- 🔍 Rarity models: The chance of selling is higher if it is a unique engine from a refrigerator ZIL or Saratovwhich is difficult to find on sale.
- 🛠️ Serviceability guarantee: The buyer of used equipment always requires checking, which in the case of a sealed compressor is extremely difficult to do without connecting to the system.
- 💰 Price competition: New a compressor costs from 3,000 to 6,000 rubles, so a used option makes sense only at a price 3-4 times lower than a new one.
If you still decide to put the engine on the bulletin board, be sure to indicate the refrigerator model, year of manufacture and, if possible, the results of measuring the winding resistance. Multimeter will show whether there is an open circuit, which is the primary sign of viability. However, you should not count on a quick sale: most often such advertisements hang for months.
Why don’t craftsmen like used compressors?
An installed used compressor has an unpredictable lifespan. Unlike the new one, it already has wear on the cylinder-piston group. In addition, when replacing, a thorough purging of the system and replacement of the filter-drier are required, which increases the cost of the work, making the purchase of a used unit economically unprofitable for the client.
Selling for scrap metal: calculation of weight and price
The most realistic scenario for monetizing an old engine is to hand it over to a collection point for ferrous and non-ferrous scrap. Here the price is determined based on the weight and category of the metal. The compressor belongs to the category of "electric motor" or "motor", but is often assessed simply as black scrap with a premium for copper.
To understand how much money you can get, you need to know the internal structure. Inside the sealed casing there is a stator with copper winding, a rotor and steel plates. The yield of pure copper averages from 0.5 to 1.2 kg, depending on the power and year of manufacture. The rest is steel, which costs much less.
Let's look at approximate indicators for different types of compressors in the table below. Please note that the data is average, since manufacturers can change designs.
| Compressor type | Total weight (kg) | Approximate copper yield (kg) | Intake category |
|---|---|---|---|
| Soviet (DH, FY) | 9.0 – 11.0 | 0.9 – 1.2 | Electric motor scrap |
| Imported (old) | 7.0 – 9.0 | 0.6 – 0.8 | Black scrap (grade) |
| Modern (inverter) | 5.0 – 7.0 | 0.4 – 0.6 | Colored scrap (analysis) |
| Industrial (small) | 15.0 – 20.0 | 1.5 – 2.5 | Electric motor scrap |
When handing over, it is important to understand that many collection points will not cut the compressor in front of you. They will accept it for the price of black scrap if it is not opened. To get a price for copper, you will have to open the engine yourself, which requires time, tools and skills.
Technology for extracting non-ferrous metals
If your goal is to maximize profits, you will have to do dismantling. This process is labor-intensive and dirty. The first step is to drain the oil, which can be aggressive and have a specific odor. Then you should open the steel case.
To open the case, an angle grinder is usually used (grinder). A circular cut is made in the middle of the compressor. It is important to observe safety precautions here: flying sparks can ignite oil vapors, so it is better to carry out work outdoors.
- 🔨 Disassembly: After removing the cover, the internal “filling” is removed. The stator with the winding is separated from the set of steel plates.
- 🔥 Burning: Some "craftsmen" burn out the winding to quickly remove copper, but this is prohibited by environmental standards and reduces the cost of scrap (overheated copper is valued lower).
- ⚖️ Sorting: Copper, aluminum and steel need to be placed in different containers. Mixed scrap is always accepted at the price of the cheapest component.
⚠️ Attention: There may be refrigerant inside the compressor. Although the amount of it in older models is small, it can come out under pressure when heated or subjected to a strong impact. Work in a ventilated area and use safety glasses.
Is the game worth the candle? Often the time spent and the consumption of discs on the grinder do not pay for the difference in price between delivery of assembled copper and delivery of cut copper. If you do not have experience, it is easier to hand over the unit as is, having first cut off only the copper circuit.
☑️ Preparing the compressor for delivery
Where to look for buyers and collection points
Finding a place to sell the old engine depends on the chosen strategy. If you want to pass it quickly and without unnecessary questions, you need reception points scrap metal. They are in every major city and often offer removal services if the volume of the shipment is large (for example, you are handing over 5-10 refrigerators at once).
Online platforms are suitable for sale as spare parts or for creative people. Avito, Yula and specialized forums are places where masters and kulibins live. Here it is important to write the description correctly: indicate that the compressor was “removed from the working refrigerator” (if this is the case) or honestly write “for spare parts/for disassembly.”
There are also specialized companies involved in the disposal of household appliances. They can pick up the entire refrigerator, but rarely pay money for it - more often, disposal is free or even paid for the owner if the equipment requires complex processing of refrigerants.
Legal and environmental aspects of disposal
Freon may remain in the circulation system, which, when released into the atmosphere, destroys the ozone layer. Therefore, simply throwing the compressor into a trash can near your home is illegal and unethical. refrigerant (freon), which when released into the atmosphere destroys the ozone layer. Therefore, simply throwing the compressor into the trash can at home is illegal and unethical.
The legislation of many countries, including the Russian Federation, regulates the management of waste electrical equipment. Official recycling involves the recovery and neutralization of refrigerants, as well as the proper recycling of oils. By handing over equipment to official collection points, you contribute to compliance with these standards.
In addition, with mass delivery (for example, an organization) is required to prepare appropriate documents (disposal acts) confirming that the waste has been transferred to a licensed operator. For a private person, just a check or receipt of acceptance is enough.
Is it possible to return a compressor if it is filled with oil?
Yes, you can. Metal collection points accept engines with residual oil. However, the weight of the oil may be deducted from the total weight or the product may be accepted at a lower price (“contaminated”). It is better to drain the oil in advance.
How much does a standard refrigerator compressor weigh?
Weight varies from 7 to 12 kilograms depending on the model and year of manufacture. Soviet models are heavier due to the thicker body metal.
Are there precious metals in the compressor?
In industrial quantities - no. The relay contacts may contain silver, but its quantity is so small (fractions of a gram) that extraction does not make economic sense.
What to do if the collection point refuses to accept it?
Refusal is possible if the point does not have a license for certain types of waste or the containers are overfilled. Try to find another point or call a specialized service for recycling household appliances.
Can the compressor be used for other purposes?
Yes, they are used to make popular compressors for airbrushing, inflating wheels and pneumatic tools. To do this, you need to remove the refrigerant, replace the oil and equip the unit with a receiver and a pressure regulator.
