How much copper is contained in the refrigerator motor: analysis by model and methods of extraction

Have you ever wondered why old refrigerators are so readily accepted at scrap metal collection points? It's all about compressor the heart motor of the unit, inside of which valuable copper is hidden. But how much is there really? Is it worth disassembling the equipment for the sake of it, and how to do it correctly, without harming yourself and others?

In this article we will figure out how much copper is contained in refrigerator engines of different brands and years of manufacturehow to extract it as efficiently as possible, and how much this process will cost, taking into account the cost of dismantling. You'll also learn which models are the most brassy and which are a waste of time. Detailed calculations, comparison tables and step-by-step instructions will help you make an informed decision.

Why is copper in a refrigerator so valuable?

Copper is one of the most sought-after non-ferrous metals on the scrap market. Its high thermal conductivity and corrosion resistance make it an ideal material for windings of electric motors, including refrigerator compressors. But why exactly are refrigerators so interesting to buyers?

The point is copper concentration: unlike small household appliances (for example, microwaves or vacuum cleaners), where copper is scattered across many small parts, in a refrigerator it is concentrated in one unit - the compressor. This simplifies extraction and increases profit per unit of equipment.

• 💰 High price: in 2026, collection points pay from 600 to 900 rubles per kg of pure copper (depending on the region and quality of scrap).
• 🔄 Easy to recycle: copper from compressors contains virtually no impurities, which simplifies its reuse.
• ♻️ Environmentally friendly: by handing over a refrigerator for scrap, you prevent freon and oils from entering the environment.

However, not everything is so simple. In the compressor, the copper is “hidden” under a layer of varnish and insulation, and the motor itself is hermetically sealed. To get to the precious metal, you will need tools, time and knowledge of safety precautions.

How much copper is in the compressors of different refrigerators?

The amount of copper in the engine depends on compressor power, year of manufacture i refrigerator brand. Modern models (after 2010) often save on copper, replacing it with aluminum or reducing the cross-section of the windings. But Soviet and early foreign refrigerators can pleasantly surprise.

Below is a table with the approximate copper content in compressors of popular brands. The data is based on analysis of real specimens and may vary within ±15%.

Please note: indicated in the table weight of pure copper, which you will receive after cleaning the windings from varnish and insulation. The raw weight of windings with insulation can be 1.5–2 times greater!

⚠️ Attention: Copper prices greatly depend on the region and the purity of the metal. In Moscow and St. Petersburg, reception centers can pay 10–20% more than in small cities. Before delivery, check the current rates with local buyers.

How to determine the compressor model and its “copper” potential?

To find out exactly how much copper your refrigerator hides, you need to identify the compressor. To do this:

1. Unplug the refrigerator and move it away from the wall.

2. Remove the back cover (if there is one) or inspect the bottom of the unit. The compressor is a black “barrel” with tubes and electrical contacts.

3. Find a sticker with markings. It is usually located on or near the compressor housing. Look for inscriptions like Embraco, Secop, Danfoss, Matsushita or DHM.

If the sticker is worn off or missing, pay attention to:

• 🔧 Shape of the compressor: Soviet models (for example, DXM-5) have a characteristic cylindrical body with cooling fins. Modern inverter compressors (LG Linear) are more compact and smooth.
• 📏 Size: the larger the compressor, the more copper it contains. For example, ZIL-63 weighs about 15 kg, and its windings contain up to 2.5 kg of copper.
• 🔌 Connection type: old compressors have three contacts (for the starting and operating windings), new ones - often two (inverter models).

After identifying the model, check it in the table above or search for data on the Internet using the query “[compressor model] copper weight". For example: Embraco EG80HLE copper content.

Step-by-step instructions: how to extract copper from compressor?

We warn you right away: disassembling a compressor is a labor-intensive and potentially dangerous process. Inside there is freon (even in non-working refrigerators!) and oil, which, if handled incorrectly, can cause harm to your health. If you are not confident in your abilities, it is better to take the entire refrigerator to a scrap metal collection point - they will disassemble it there. professionals.

If you decide to dismantle it yourself, follow these instructions:

Step 1: Removing the compressor

Carefully bite off the tubes connecting the compressor to the cooling system at a distance of 10-15 cm from the housing. dangerous! grinder or pipe cutter. Do not try to unsolder the tubes - it is useless and dangerous!

Disconnect the electrical contacts (after photographing the connection diagram if you plan to use the compressor in the future, unscrew the fastening bolts and remove the compressor.

Step 2: Opening). housing

The compressor is sealed hermetically, so it needs to be cut. To do this:

1. Secure the compressor in a vice vertically (pipes up) to avoid oil leakage.

2. Use a grinder with a metal disc to make a cut along the seam of the housing (usually it is visible as a thin line). The depth of the cut is 2–3 mm.

3. Carefully split the housing with a hammer and chisel. Be prepared for oil and freon residues to leak out!

Step 3: Removal. windings

Inside you will see:

• 🔄 Rotor and stator —this is where copper is concentrated.
• ⚙️ Piston group (in piston compressors) - copper here is only in small parts.
• 🛢️ Oil - it must be drained into a separate container and disposed of as waste of hazard class 3-4.

To extract copper:

1. Remove the stator (fixed part) - it is a cylinder with wound copper wire.

2. Cut or saw the frontal parts of the windings (they do not contain copper).

3. Carefully remove the windings from the stator, prying them up with a screwdriver. Take your time - the wire is fragile!

Step 4: Cleaning the copper

The removed windings are covered with a layer of varnish and insulation. To get pure copper:

1. Burn the insulation in the open air (for example, in a metal bucket). Do not do this indoors! The varnish releases toxic substances when burned.

2. After calcination, tap the windings on hard surface - ash and insulation residues will fall off.

3. Rinse the copper with water and dry.

⚠️ Attention: When burning insulation, use respirator and stay downwind. Varnish vapors can cause poisoning! An alternative is mechanical cleaning (scraping the varnish with a knife), but this will take 3-4 times longer.

What to do with leftover freon?

Freon in household refrigerators (usually R12 or R134a) is not flammable, but when heated above 250°C it decomposes with the formation of toxic gases (phosgene, chlorine). If the compressor stood idle for a long time, the freon could evaporate, but it’s not worth the risk. It is better to take the compressor to a recycling point, where the freon will be pumped out professionally.

How much can you earn from copper from a refrigerator?

Let's calculate using a specific example. Let's say you have a Soviet refrigerator ZIL-63 with a compressor KV-6containing 2.3 kg of copper. Let's consider two scenarios:

Scenario 1: Self-analysis

• 🔨 Costs:
  • Disc for grinder (100 ₽).
  • Gloves and respirator (300 ₽).
  • Time (3–5 hours).
• 💰 Income:
  • 2.3 kg × 800 ₽/kg (average price in 2026) = 1 840 ₽.
• 📉 Total: ~1,440 ₽ net profit (less costs).

Scenario 2: Delivery of the entire refrigerator

• 🚛 Costs:
  • Delivery to the collection point (200–500 ₽, if you don’t have your own car).
• 💰 Income:
  • Reception points pay for the whole refrigerator from 500 to 1,500 ₽ (depending on the model and weight).
• 📉 Total: 300–1,000 ₽ profit.

The conclusion is obvious: independent disassembly is more profitable, but only if you have the time, tools and skills to work with metal. For a one-time promotion, this may not pay off, but if you plan to dismantle 5-10 refrigerators, the profit will increase multiple.

Which refrigerators should not be disassembled for the sake of copper?

Not every appliance will justify the cost of disassembly. Here are the models that are better to hand over entirely or not to touch at all:

• 🚫 Inverter refrigerators (LG, Samsung, Hitachi after 2010): contain little copper (0.3–0.6 kg), and their compressors are difficult to disassemble without special equipment.
• 🚫 Small refrigerators (up to 100 l): the compressors in them are miniature, and copper there is no more than 0.2–0.4 kg.
• 🚫 Refrigerators with the No Frost system: their compressors are often less powerful than in drip models.
• 🚫 Equipment with aluminum windings: some modern models (for example, Whirlpool with compressors Embraco Fullmotion) use aluminum instead of copper. You can check this with a magnet - copper does not magnetize!

Also avoid disassembling compressors that:

• 🔥 Have traces of severe overheating (blackened housing, melted contacts) - copper in them could oxidize.
• ☢️ Were used in enterprises (for example, medical or industrial refrigerators) - they may contain hazardous substances.
• 🔧 Already opened earlier - there is a high risk that copper has already been removed there.

⚠️ Attention: If the refrigerator was operated on ammonia (rare, but found in older industrial models), its compressor must absolutely not be disassembled! Ammonia reacts with copper, forming explosive compounds.

Alternative ways to make money on old refrigerators

If the copper in your refrigerator does not justify the cost of disassembly, consider others options:

• 🔄 Sale of a working refrigerator:
  • Soviet models (ZIL, Saratov, Donbass) are in demand among collectors and summer residents. Price: from 2,000 to 10,000 ₽.
  • Foreign brands of the 90s (Snaige, Nord) can be sold for 1 500–5 000 ₽.
• ♻️ Sale for spare parts:
  • Compressors from Atlanta or Indesita bought by refrigerator repair shops (price: 500–2 000 ₽).
  • Door seals, shelves and drawers can be sold separately on Avito or Yule.
• 🎨 Handmade and art projects:
  • Original cabinets, bar counters or even mini-saunas are made from refrigerator cases.
  • Compressors are used to create homemade ones sandblasters or air compressors.

Example: a refrigerator Minsk-15M 1985 in working condition can be sold for 4 000–6 000 ₽, whereas copper from its compressor will bring everything 1 200–1 500 ₽. It is more profitable to find a buyer!

Legal nuances: is it possible to legally disassemble refrigerators?

In Russia, dismantling household appliances for spare parts or scrap is not prohibited, but there are several important points:

• 📄 Freon recycling: according to Federal Law No. 89-FZ “On Production and Consumption Waste”, freon belongs to hazard class 3-4 waste. It cannot simply be released into the atmosphere. Only licensed organizations can dispose of freon. data-i="268">Disposal of freon
• 🚛 Transportation: if you are transporting more than 5 refrigerators at a time, this can be regarded as entrepreneurial activity (Article 2 of the Civil Code of the Russian Federation). In this case, you will need to register as an individual entrepreneur or self-employment.
• 🏠 Disassembly in residential premises: according to According to Decree of the Government of the Russian Federation No. 354, dismantling equipment using an angle grinder or welding machine in an apartment is prohibited (noise and fire hazard). It is better to do this in a garage or in a country house.

In practice, few people monitor the disassembly of 1-2 refrigerators, but if you plan to do this regularly, worth:

1. Conclude an agreement with a scrap metal collection point on an ongoing basis.

2. Get self-employment (if income exceeds 2.4 million ₽/year).

3. Find a recycling point that will accept freon and oil (usually it’s free).

⚠️ Attention: If you hand over refrigerators for scrap metal as an individual, collection points do not have the right to demand documents from you. But if you bring equipment by truck or regularly, they may ask for a passport and explain the origin of the cargo.

FAQ: Frequently asked questions about copper in refrigerators

Is it possible to remove copper from the refrigerator without a grinder?

Theoretically, yes, but it is extremely labor-intensive. Alternative methods:

• 🔨 Chisel and hammer: you can split the body, but there is a risk of damaging the windings.
• 🔥 Heating: if you heat the compressor housing to 200–250°C, the solder may melt, but this is dangerous (risk of explosion of freon residues!).
• 💦 Hydraulic press: suitable for industrial disassembly, but not for home use.

The grinder remains the fastest and safest tool.

How much copper is in the refrigerator Stinol 2005?

Refrigerators Stinol of this period were usually equipped with compressors Embraco EG or Secop (Danfoss)They contain:

• 0.9–1.2 kg of copper v windings.
• 0.1–0.2 kg in small parts (contacts, tubes).

Total: 1.0–1.4 kg. At a price of 800 ₽/kg, this is 800–1 120 ₽.

Is it dangerous to breathe vapors when burning copper insulation?

Yes, very dangerous! When varnish and insulation burn, the following are released:

• 🌫️ Phenol —causes dizziness and nausea.
• 💀 Formaldehyde —carcinogen, irritates the lungs.
• 🔥 Carbon monoxide —can cause to poisoning.

Be sure to use a respirator with a carbon filter (for example, 3M 6000) and work outdoors!

Where is the most profitable place to sell copper from refrigerators?

Copper prices vary by region. In 2026, the best offers are usually in:

• 🏭 Metal processing plants (for example, Russian Copper Company Yekaterinburg).
• 🚛 Large collection points (networks LomTsvetMet, VtorTsvetMet).
• 🌍 Scrap exporters (in port cities, for example, in St. Petersburg or November data-i="331">Regions:

Average prices in Russia (for 2026):

• Moscow: 800–900 ₽/kg.
• Regions: 600–750 ₽/kg.
• Far East: 550–650 ₽/kg (due to logistics costs).

Before your trip, check prices by phone - they can change daily.

Can a compressor from a refrigerator be used for other purposes?

Yes! Old compressors are used in:

• 🔧 Homemade air compressors (for painting, inflation of wheels).
• 💨 Sandblasting machines (the filtration system needs to be modified).
• 🌱 Aerators for ponds (the compressor pumps air into the water).
• 🔥 Forges (for fanning coals).

To do this, the compressor needs to:

1. Clean from oil and freon.
2. Connect to the receiver (compressed air cylinder).
3. Install filters to clean the air from oil.

Example: a compressor from Atlanta can produce up to 8 atmospheres - this is enough for painting car.
