A broken refrigerator often becomes a source of headache, especially when the question arises of disposing of bulky equipment. However, for experienced craftsmen and collectors of non-ferrous scrap, this is not garbage, but a valuable raw material that can be profitably monetized. Electric motorhidden in the compressor contains copper, steel and sometimes precious metals, which makes it a coveted trophy in the world of recycled materials.
Owners household appliances often underestimate the value of the components that they throw into a landfill. Hermetic compressor - this is not just an iron can with freon, but a complex unit that requires proper preparation before delivery. If you want to get maximum profit and not violate environmental standards, you need to clearly understand who exactly is interested in purchasing such parts and how to properly formalize the deal.
The scrap acceptance market is heterogeneous: there are large factories, small private shops and resellers working “in garages”. Each of them offers its own conditions, but not everywhere you will be welcome with just a motor. In this article we will examine in detail how the method of dismantling affects the final amount and why you should beware of offers that seem too profitable. where they accept engines from refrigerators, how the method of dismantling affects the final amount and why you should beware of offers that seem too profitable.
⚠️ Attention: Handing over unassembled compressors is often equated to handing over black scrap, the price of which is several times lower than for copper.
Typology of collection points: where to carry the compressor?
The first question that arises when you want to hand over equipment is finding a place. The market is divided into several segments, and each has its own characteristics of interaction with customers. Stationary collection points metal is the most obvious option. They work officially, have scales and a price list, but often require a passport and may refuse to accept single copies due to the small volume of the batch.
Private resellers and small “receptions” in courtyards or garage cooperatives are more flexible. They are ready to accept even one engine, but there is a high risk of encountering dishonest weighing or a low price. Electric motor in their eyes, this is a product whose quality needs to be checked, so they may require cutting it right in front of you to assess the non-ferrous metal content.
There are also specialized companies for recycling household waste technology. They often offer a pickup service, but in this case you are unlikely to get any money - most likely, they will just pick up your old refrigerator for free. If your goal is sales, then it is better to focus on those who specialize in non-ferrous scrap.
- 🏢 Large processing plants - accept large quantities, require documents, low price per unit.
- 🚛 Mobile teams - pick up the equipment themselves, but pay the minimum or do not pay at all.
- 🏠 Private points in courtyards - high flexibility, cash payment, but the risk of fraud when weighing.
When choosing a location, consider logistics. The compressor weighs from 8 to 12 kg, and carrying it across the city on public transport can be inconvenient. The highest prices are usually offered in industrial zones where scrap from enterprises flows.
Economic feasibility: copper or ferrous scrap?
The main question that determines the cost of your engine is a classification of metal. The compressor consists of a steel housing (black scrap) and motor windings (non-ferrous scrap - copper). If you hand over the entire unit, it will be valued at the price of ferrous metal, which amounts to pennies. The real value is hidden inside.
To get a fair payment, the engine must be removed and, ideally, sawed. Inside asynchronous motor there is pure electrical copper. Receivers pay 3-4 times more for it than for steel. However, the extraction process requires time and tools (grinder, hacksaw, vice), which also needs to be taken into account in the profit equation.
Some collection points offer an "express assessment" service without cutting, but they always work with a discount on the risk. They don't know exactly how much copper is inside, and they anticipate possible losses. If you hand over the engine in a casing, you will actually give the receiver part of your profit.
⚠️ Attention: Never agree to hand over a compressor as a “solid product” if the copper winding is clearly visible in it - this is a direct loss of money.
The process of dismantling and preparing for delivery
In order for your product to be accepted at the maximum price, proper preparation is necessary. Simply unplugging the compressor from the refrigerator is not enough. You will need a set of tools: wrenches, pliers and, preferably, an angle grinder (grinder). The process begins by disconnecting the equipment from the network and removing the protective casing at the back of the refrigerator.
Next, you need to carefully disconnect the tubes. Important: if there is still freon in the system, its release into the atmosphere is prohibited by environmental standards, although in practice at home this is often ignored. After disconnecting the tubes, the compressor is removed from the frame. At this stage, many stop, but for maximum profit you need to go further.
The next step is cutting. The compressor housing (ferrous metal) must be separated from the electric motor. This is done by sawing through the weld seams. Inside you will see copper heat exchanger tubes and the motor itself. The motor also requires opening to remove the copper coil. The purer the copper at the output, the higher the price per kilogram.
☑️ Engine preparation checklist
When working with an angle grinder, use safety glasses and gloves. Metal shavings and sparks can cause injury. In addition, industrial oil, which is a contaminant, may remain inside the compressor. Draining the oil in a separate container before delivery will show the receiver that you are professional in your approach to the matter and will eliminate questions about the weight of the liquid.
Price table: what to expect from the receivers
Scrap pricing is a dynamic process and depends on stock quotes of the London Metal Exchange (LME). However, we can highlight the middle ranges that you should focus on when handing over engines. Prices may vary depending on the region, the volume of the delivery batch and the current demand for copper.
| Type of raw materials | Condition | Approximate price (RUB/kg) | Comment |
|---|---|---|---|
| Entire compressor | Assembled, with oil | 15 - 25 | Rated as black scrap |
| Engine in casing | Without tubes, with oil | 40 - 60 | Average category |
| Copper winding | Pure, without insulation | 550 - 650 | Maximum cost |
| Steel body | After cutting | 10 - 15 | For rent separately |
As can be seen from the table, the difference in price between the delivery of a solid compressor and pure copper is colossal. However, it is worth considering labor costs. If you only have one engine, it may not be worth the time to completely dismantle it, unless you are doing it for sport or the environment.
Large distributors with dozens of compressors often organize a disassembly production line, which makes the process cost-effective. For a private person who has one old refrigerator, the balance of time and money may shift towards delivery in a more ready, but less profitable form.
Technical features and types of engines
Not all engines are the same. Refrigerators use different types of compressors and their non-ferrous metal content varies. Standard piston compressors, which are found in most old refrigerators (for example, Biryusa, Atlant, ZIL), have a classic design with easily accessible copper winding.
Modern inverter compressors are more complex. They may contain rare earth metals in the rotor magnets, which theoretically increases their value, but the practical recovery of these materials in a garage environment is close to zero. Such motors are often accepted as is, without requiring disassembly, but the price for them will not be astronomical.
It is also worth paying attention to the condition of the winding. If the engine is burnt out and blackened, the price of copper can be reduced by 10-15% due to the need for additional cleaning and weight loss when burning the insulation. Burn insulation is an additional expense for the processor.
Environmental aspects and safety of disposal
In the pursuit of profit, we must not forget about the environment. Inside the compressor there is technical oil, which is a petroleum product. Draining it onto the ground or into a sewer is strictly prohibited. One liter of such oil can contaminate thousands of liters of water, making it unsuitable for life.
In addition, in older models of refrigerators, R12 freon, which destroys the ozone layer, could be used as a refrigerant. Modern refrigerants (R600a - isobutane) are fire hazardous. When sawing a compressor, sparks from an angle grinder can ignite residual gas if proper degassing has not been carried out.
⚠️ Attention: Before starting cutting work, be sure to drill a hole in the compressor housing away from sparks to release residual pressure and freon vapor.
When handing over the engines to the official points, you guarantee that waste oils and hazardous gases will be disposed of according to standards. Private owners often simply drain the oil into the nearest ditch. When choosing a delivery location, think not only about your wallet, but also about the environment in which your children will live.
Legal nuances and documents
Scrap delivery is a business process that is regulated by law. Large collection points are required to keep strict records: they require the passport details of the donor, especially if the transaction amount exceeds a certain limit or non-ferrous scrap is handed over. This is a measure to combat theft (for example, theft of cable products or infrastructure elements).
If you hand over motors from refrigerators that are not your property (for example, found in a landfill or dismantled someone else's abandoned refrigerator), you may be asked for an explanation. Scrap metal owners do not have the right to accept non-ferrous metals from undocumented persons or from minors.
For a one-time delivery of one or two engines, it is usually enough to simply present a passport for entry in the journal. If you plan to do this regularly, you may have to register as an individual entrepreneur or self-employed in order to legally work with receipts and receive payment on the card without being blocked by the bank.
Frequently asked questions (FAQ)
How much does the engine of a regular refrigerator weigh?
The weight of the compressor is assembled (housing + motor + tubes) usually ranges from 8 to 12 kg. The weight of pure copper that can be extracted from the motor windings varies from 0.5 to 1.2 kg, depending on the power and model of the unit.
Will an engine be accepted if it is rusty or wet?
Rust reduces the category of scrap, but does not make it unusable. The wet metal is weighed taking into account moisture or allowed to dry. The main thing is the absence of a large amount of foreign debris, concrete or ice inside.
Is it possible to take the engine from a refrigerator to a regular glass container collection point?
No, glass container collection points do not deal with metal. You need specialized collection points for ferrous or non-ferrous scrap. Sometimes such points are located nearby, but these are different organizations.
What to do if the reception point refuses to accept one engine?
Refusal to accept small batches is a common practice of large bases. In this case, it is worth looking for private collection points in the courtyards or agreeing with neighbors to jointly hand over the accumulated scrap.
Is there gold or silver in the refrigerator engine?
In standard household compressors, precious metals (gold, silver, palladium) are practically not used. The main value is electrical copper and steel. The content of precious metals is typical for the electronic control board (if there is one), but not for the motor itself.
