Copper in a refrigerator compressor: where is it hidden and how much can you get?

The compressor is the “heart” of the refrigerator, and many people wonder: is there copper in it?, and if so, how much can be extracted? This issue is especially relevant for those involved in selling non-ferrous scrap metal or repairing equipment. The answer is not as simple as it seems: it all depends on the type of compressor, its model and even the year of manufacture of the refrigerator.

In this article we will look in detail at where exactly copper is hidden in the compressor, in what quantity (with specific numbers for popular models), and how to safely remove itwithout damaging others details. You will find out whether the game is worth the candle, if the goal is to sell copper, and what pitfalls await beginners. For clarity, we present tables with the weight of copper components and give a checklist for disassembly.

Why should there be copper in a refrigerator compressor?

Copper is one of the best conductors of heat and electricity, which is why it is actively used in refrigeration technology. In a compressor, it performs several key functions:

• 🔌 Electric motor winding —a copper wire (enameled) is wound around the rotor or stator, providing a magnetic field for the motor to operate.
• 🔄 Heat exchanger tubes —in some compressor models, copper is used to transfer refrigerant (freon) between nodes.
• 🛠️ Contact groups and terminals —for reliable connection of electrical circuits.

Without copper, the compressor will either not be able to operate efficiently, or will require more bulky and expensive alternatives (for example, aluminum windings that conduct current less well). However not all compressors are equally rich in copper - it all depends on their type and design.

Types of compressors and copper content in them

Refrigerator compressors are divided into three main types, and in each of them copper is distributed differently. Let's take a closer look:

1. Linear (piston) compressors —the most common in old and budget models (Indesit, Atlant, Biryusa). Here, copper is concentrated in the winding of the electric motor (up to 300–500 grams in large models) and in the tubes of the refrigerant circuit (another ~50–100 grams).
2. Inverter compressors —used in modern refrigerators (Samsung, LG, Liebert). There is less copper here (about 150–250 grams), but it is of a higher quality (pure, without impurities).
3. Rotary compressors - are less common (for example, in some models Electrolux). There is a minimal amount of copper in them (up to 100 grams), since the winding is often replaced with aluminum.

It is important to understand that the weight of copper depends not only on the type of compressor, but also on its power. For example, in industrial refrigerators (for example, for shops), compressors can contain up to 1–1.5 kg of copper, while in household ones - rarely more than 300 grams.

How to distinguish inverter compressor from a linear one?

Inverter compressors operate almost silently and do not have sudden switching on/off. The case is often labeled "Inverter" or "Digital Inverter". Linear compressors emit a noticeable hum and periodically turn off.

Table: Copper content in compressors of popular refrigerators

Below is an indicative table with the weight of copper components in compressors of refrigerators of different brands. The data is based on disassembly of standard models and may vary depending on the modification.

Please note: the table indicates net weight of copper, without taking into account the insulation (enamel) on the winding wires. When selling for scrap metal, it will have to be removed (we'll talk about this later).

⚠️ Attention: The weight of copper in inverter compressors is often underestimated for marketing purposes. The actual amount may be 10–15% less than stated in the technical specifications.

Where exactly is copper hidden in the compressor?

To extract copper, you need to know in which parts of the compressor it is located. Let's look at the design using the example of a typical linear compressor (the most common option):

• 🔧 Stator winding —the main source of copper. The wire is wound around a core and covered with a layer of varnish (enamel). To get to the copper, the winding will have to be burned or mechanically cleaned.
• 🔄 Refrigerant circuit pipes - thin copper tubes connecting the compressor to the condenser and evaporator. They can be carefully cut off and returned separately.
• ⚡ Terminal block - here copper is used for contacts. The weight is minimal (10–30 grams), but the metal is clean and easily removable.
• 🛡️ Protective casing — in some models, copper screen wires are laid inside the casing (rare, but found).

B In inverter compressors, copper is most often concentrated in the rotor and stator, and the tubes can be made of aluminum or stainless steel. Before disassembling, be sure to check the material of the tubes with a magnet: copper do not magnetize, unlike steel.

How to remove copper from a compressor: step-by-step instructions

Removing copper from a compressor is not an easy task. It requires care, tools and safety precautions. Below is an algorithm of actions, but remember: if you are not confident in your abilities, it is better to contact a specialist.

Disconnect the refrigerator from the network at least 24 hours in advance|Prepare your workplace (table, vice, lighting)|Put on protective gloves and glasses|Prepare tools: grinder, soldering iron, wire cutters, screwdrivers|Check the compressor for residual pressure (carefully!)-->

Step 1: Removing the compressor from the refrigerator

Disconnect the compressor from the cooling system by cutting the tubes copper pipe cutters or a grinder. Be careful: there may be refrigerant (freon) remaining in the system, which can cause frostbite if it comes into contact with the skin. Work with gloves and in a well-ventilated area.

Step 2: Disassembling the compressor housing

The compressor housing is usually welded or riveted. To open it, you will need:

• 🔨 Carefully cut off the top part grinder (without touching the internal parts!).
• 🔧 Or drill out the rivets drill and separate the halves of the housing.

Step 3: Removing the winding

The stator winding is the main source of copper. To get it:

1. Remove the rotor (central shaft).
2. Using soldering iron unsolder the winding leads from the terminals.
3. Carefully remove the winding from the core (you can pry it out with a screwdriver).

Step 4: Cleaning copper from insulation

The copper wire is covered layer of varnish (enamel) that needs to be removed. There are two ways:

• 🔥 Thermal: burn the insulation on an open fire (for example, fire or with gas burner). Minus: copper can oxidize, and its price for scrap metal will fall.
• 🧹 Mechanical: clean the wire sandpaper or metal brush. Plus: copper remains clean, but the process is long.

⚠️ Attention: When burning insulation, toxic gases are released (formaldehyde, phenol). Do this only on the street, away from residential premises, and use a respirator. How much can you earn on copper from a compressor? question: respirator.

How much can you earn from copper from a compressor?

Now the main question: is the game worth the candle? Let's calculate the potential profit using the example of a compressor from a refrigerator Atlant MHM 1705 (see table above), which contains about 500 grams of copper.

Current prices for copper at scrap metal collection points (for 2026):

• 💰 Pure copper (without insulation): 600–800 rub/kg.
• 💰 Copper insulation (unrefined): 300–500 rub/kg.
• 💰 Copper tubes: 500–650 rub/kg (depending on diameter).

Calculation for our example:

• Wrapping (400 g) × 700 rub/kg = 280 rub.
• Tubes (100 g) × 600 rub/kg = 60 rubles.
• Total: 340 rubles per compressor.

Please note that:

• ⏱️ For disassembling one compressor goes 1.5–3 hours (depending on experience).
• ⚠️ You will have to spend money on discs for grinders, soldering acid and other consumables (~100–200 rubles).
• 📉 Copper prices fluctuate —before delivery, check the current tariffs in your region.

Alternative ways to use the compressor

If the goal is not only copper, then the compressor from the refrigerator can be used differently:

• 🔧 Homemade compressor for painting - suitable for. small work (for example, painting furniture). Some modifications will be required: installation of a receiver and a pressure regulator.
• 🚗 Inflating tire —if the compressor is still working, it can be connected through a gearbox to inflate the wheels of a bicycle or car.
• 💨 Airbrush or sandblaster —if you have experience, you can assemble a mini-sandblaster for cleaning small parts.
• 🔥 Forge or forge —a compressor is used to pump air into the forge (a powerful model will be required).

Before disassembling the compressor for copper, evaluate its technical condition. If it is in good working order, it may be more profitable to sell it entirely on Avito or Yula —working copies are bought for repairing refrigerators or alterations.

⚠️ Attention: When using the compressor for other purposes (for example, for inflating tires), be sure to set safety valvethe pressure in refrigerator systems may exceed 10 atmospheres - this is dangerous!

FAQ: Frequently asked questions about copper in refrigerator compressors

❓ Which compressors contain the most copper?

The largest amount of copper is contained in linear (piston) compressors old Soviet and post-Soviet refrigerators (ZIL, Minsk, Atlant, Biryusa). In them the windings are more massive and the tubes are thicker. In inverter compressors there is less copper, but it is cleaner.

❓ Is it possible to remove copper without disassembling the compressor?

No. Copper is inside the winding and tubes, so you can’t get it out without opening the case. The exception is copper tubes, which can be cut off from the outside, but their weight is significant. usually does not exceed 50–100 grams.

❓ How to distinguish a copper tube from an aluminum one?

Copper is reddish tintand aluminum is silvery. Also, copper does not magnetize is more ductile (it is more difficult to break with your hands). When tapped, copper makes a more ringing sound.

❓ How much copper is in a compressor from an industrial refrigerator?

In industrial refrigeration units (for example, in ice cream display cases) compressors contain from 800 grams to 1.5 kg of copper. However, their disassembly is more difficult due to their size and high pressure in the system.

❓ Is it possible to sell the entire compressor for scrap?

Yes, but the price will be lower, than when separated into components. A solid compressor is accepted as ferrous scrap metal (at a price of ~10–20 rubles/kg), while pure copper costs 30–50 times more.
