The question about the exact content of non-ferrous metals in old household appliances often arises among those who are recycling or planning to sell the unit for scrap. Brand refrigerators Indesit, widespread in the post-Soviet space, contain a certain amount of copper, which can be extracted with the right approach. However, it is important to understand that simply weighing the entire device is not enough - the valuable metal is concentrated in specific components that require dismantling.
Many mistakenly believe that the entire body or internal lining contains precious ore, but the reality is more prosaic and more specific. The main volume non-ferrous metal is hidden in the motor-compressor and, to a lesser extent, in the piping system. In order to make a real profit when handing over scrap, you need to know the structure of the unit and safety precautions when disassembling it.
In this article we will look in detail at where exactly copper is located in refrigerators Indesit, what is its approximate weight depending on the model and year of manufacture, and will also discuss the economic feasibility of independent extraction. You will receive not just dry numbers, but a complete guide to assessing recycled materials.
Where is copper located in the refrigerator design
Upon initial inspection Indesit it may seem that there are a minimum of copper elements here, since the external panels are made of steel or plastic. However, the “heart” of the refrigeration unit is the compressor, which is essentially an electric motor with copper windings. It is the coils inside the black cylindrical tank that are of greatest interest to scrap collectors.
The second place in terms of metal content is occupied by the evaporator and condenser. In older models Indesit pipes were often made of aluminum, but in more modern or specific series you can find copper elements in the refrigerant circuit. There is also a small amount of wire present in wiring and thermostats, but their volume is so small that it makes no sense to consider them as a source of income.
⚠️ Attention: In modern refrigerator models, manufacturers are increasingly replacing copper tubes with aluminum or copper-plated steel to reduce the cost of construction. Before starting disassembly, make sure that the tubes are really magnetic (steel) or non-magnetic and lightweight (aluminum), so as not to waste time.
The motor remains the key unit. Inside the sealed casing is a stator with a winding, which is almost always made of copper. The weight of this winding depends on the engine power, which, in turn, correlates with the volume of the refrigeration chamber and the energy efficiency class Indesit.
Weight of copper depending on the model and year of manufacture
The amount of useful metal directly depends on when yours was produced Indesit. The technology of the Soviet and early post-Soviet period was often made with a large margin of safety and the use of heavier materials. Modern units strive for minimalism and saving resources.
For an accurate understanding of volumes, it is worth considering the average data for various series.
Below is a table showing the approximate copper content depending on the type of compressor installed in refrigerators Indesit. This data will help you set realistic expectations before handing over the equipment.
| Compressor type / Model | Approximate winding weight (kg) | Total compressor weight (kg) | Note |
|---|---|---|---|
| Single-phase (standard) | 1.2 - 1.5 | 9 - 11 | Most common in older models |
| Powerful (for No Frost) | 1.6 - 2.0 | 12 - 14 | Higher metal content |
| Inverter (modern) | 0.8 - 1.1 | 7 - 9 | Often contains less copper, more electronics |
| Compact (small volume) | 0.6 - 0.9 | 6 - 8 | Low-power units |
As can be seen from the table, the maximum output is obtained from powerful models equipped with the system No Frost. However, in ordinary static refrigerators Indesit you can find quite a decent amount of non-ferrous metal if you assemble a batch of several pieces of equipment.
Technology for extracting copper from a compressor
The process of extracting metal from a motor Indesit requires physical effort and a basic set tools. Simply knocking the winding out of the housing will not work - it is tightly filled with varnish and pressed into place. There are two main methods: mechanical and thermal.
The mechanical method involves the use of a chisel, hammer and grinder. First, the upper part of the casing is cut off, then the “core” is removed. After this, it is necessary to knock down the assembled plates of the electric motor to free access to the coils. This is a labor-intensive process that takes a significant amount of time.
☑️ Preparation for disassembling the compressor
The thermal method, or burning, is more popular among professionals, but requires caution. The compressor is heated in a fire or oven until the varnish and insulation burn out. After cooling, the copper becomes soft and comes off easily. However, with this method, up to 10-15% of weight is lost due to oxidation, and harmful substances are also released.
⚠️ Attention: When the winding insulation is burned, toxic gases are released. The procedure can only be carried out outdoors, away from residential buildings and using respiratory protection. In enclosed spaces this is deadly.
When choosing a method, weigh your options. If you have access to a receiving facility that accepts entire or assembled compressors, there may be no point in wasting time extracting clean metal, since the price of assembled scrap is also quite competitive.
Economic feasibility of disassembly
Is it worth the gamble? To answer this question, you need to carry out simple mathematical calculations. Let’s say the price of copper in your region is 600 rubles per kg, and ferrous metal is 15 rubles per kg. The weight of the compressor Indesit is 10 kg, of which 1.5 kg is copper, the rest is steel.
If you hand over the entire compressor as black scrap, you will receive: 10 kg 15 rubles = 150 rubles. If you disassemble and get 1.5 kg of copper and 8.5 kg of steel, the calculation will be different: (1.5 600) + (8.5 * 15) = 900 + 127.5 = 1027.5 rubles. The difference is colossal, but it is only valid if you have already disassembled the unit.
Hidden costs during disposal
Do not forget to take into account the depreciation of the tool (discs for grinders, chisels), the cost of transporting the heavy refrigerator case and, most importantly, your time. If you spend 3 hours disassembling one refrigerator, your hourly rate may be lower than the minimum.
However, if you consider disassembling one single refrigerator Indesit, the cost of time and effort may not be worth it. Economic sense appears when processing a batch of 5-10 units of equipment or if you have already prepared equipment for quick cutting.
Rules for safe disposal. refrigerant
When starting disassembly, we must not forget about environmental safety. Inside the circulation system Indesit there is a refrigerant (freon). In old models it can be R12, in new ones - R134a or isobutane R600a. Simply cutting the pipes leads to the release of these substances into the atmosphere.
Refrigerants destroy the ozone layer, and isobutane, moreover, is explosive when in contact with a spark from an angle grinder. Therefore, before starting any metal cutting work, it is necessary to ensure that the system is ventilated. To do this, open the compressor in a well-ventilated area or outside.
- 🛡️ Protection: Use gloves and goggles, as scattering is possible when cutting tubes. metal shavings and oil residues.
- 🔥 Fire safety: Never start cutting or welding until you are sure that all gas has been vented, especially if you are using isobutane.
- ♻️ Ecology: Try to minimize the release of compressor oil into the soil; it also requires special disposal.
Ignoring these rules can lead not only to fines from environmental services, but also to serious injuries. Safety should always be a priority over the cost of the scrap metal received.
Comparison of Indesit with other brands
How does Indesit look compared to competitors? The Italian brand, assembled in Russia, traditionally uses reliable compressors, often produced Embraco or Danfoss (in older models), which are characterized by a high copper content. This compares them favorably with some budget Chinese analogues, where the weight of the winding can be reduced by using aluminum instead of copper.
In cheaper segments of the market you can find motors with windings made of aluminum coated with a layer of copper (copper-bonded aluminum). It is difficult to distinguish them visually, but they are much lighter in weight, and when scrapped, their price is equal to the price of aluminum, which is several times cheaper. Indesit in this regard, it retains the reputation of a brand that uses classic technologies.
Thus, older models Indesit remain the “gold standard” for recyclables collectors. Their design is predictable, and the quality of the materials allows you to count on a stable yield of non-ferrous metal during recycling.
Frequently asked questions (FAQ)
Is it possible to return the entire Indesit refrigerator without disassembling it?
Yes, many collection points accept entire household appliances, but pay for them at the price of scrap metal or mixed scrap, which is significantly cheaper than the cost of extracted copper. The benefit will be minimal.
Does the evaporator tubes contain copper?
In most modern models Indesit the evaporator tubes are made of aluminum or steel. Copper may only be found in connecting elements or in very old models. The main source is the compressor winding.
What tool is needed for disassembly?
You will need: an angle grinder with metal discs, a chisel, a hammer, pliers, safety glasses and gloves. The thermal method will require an open fire source or oven.
Does the No Frost system affect the amount of copper?
The system No Frost requires a more powerful compressor, which often means more winding wire. However, such systems also contain more plastic and fans, which have no scrap value.
Is it dangerous to open the compressor yourself?
Yes, it is dangerous. Pressure, oil and refrigerant residue may remain inside. In addition, when working with an angle grinder, there is a high risk of injury. Compliance with safety precautions is required.
