How much copper is in the Atlant refrigerator: maintenance and disposal

Question about the content of colored metals in household appliances often arises among owners planning to dispose of old equipment, or among craftsmen engaged in equipment restoration. Atlant refrigerators, produced at the Minsk plant, are among the most common in the post-Soviet space, and their design has undergone changes over the decades. Understanding exactly where Cuprum (Cu) is located is critical for correct sorting of scrap and assessing the potential profit when delivering it to collection points.

In the modern world, where resources are limited, recycling is becoming not just a trend, but a necessity. On average, one Atlant refrigerator contains from 0.5 to 1.5 kg of pure copper, however, this figure varies greatly depending on the year of manufacture, the volume of the chamber and the type of refrigerant used. Old Soviet models can contain significantly more of this metal compared to modern energy-efficient units, where engineers strive to minimize the use of expensive materials.

This article will help you understand the structure of the refrigeration circuit and accurately determine the location of the valuable metal. We'll look at the differences between models from different years, touch on safety issues during dismantling, and answer frequently asked questions. Remember that self-disassembly requires compliance with safety precautions, since gas may be under pressure inside the system, and some components may be toxic if damaged.

Location of copper elements in the structure

The main volume of copper in the refrigerator Atlant is concentrated in the heat exchange circuit, which ensures circulation refrigerant. This is where the process of heat removal from the chambers to the outside occurs. Traditionally, this circuit is divided into two main parts: the condenser (located at the back or built into the walls) and the evaporator (located inside the freezer or refrigerator compartment). PipelinesPipelines

The compressor, which is the “heart” of the refrigerator, also contains a significant amount of copper, but it is located inside the electric motor windings. To get to this copper, you need to completely open the compressor housing, which is impractical and dangerous to do at home. Therefore, when assessing scrap, only the outer contour, accessible for extraction without complex technical operations, is usually considered. In older models, the pipes could be steel with a copper coating, which reduces their value.

It is important to note that in models with the system No Frost the amount of copper in the evaporator may be less, since aluminum radiators are used for blowing, and only the supply lines remain copper. At the same time, capacitors in most cases remain copper or steel, but with high thermal conductivity. An accurate determination of the pipe material is possible by the color of the cut and the reaction to the magnet.

⚠️ Attention: When trying to remove copper from the refrigeration circuit, do not cut the pipes under any circumstances if there is still freon under pressure in the system. This may result in oil splashing or eye injury. First, you need to carefully vent the gas in a well-ventilated area.

The influence of the year of manufacture on the metal content

The year of manufacture of the refrigerator plays a decisive role in determining the amount of non-ferrous metal. In the era of the USSR and in the first years of independence of Belarus, engineers did not prioritize saving materials, so pipes were made with a margin of safety and from pure copper. Modern environmental standards and the high cost of raw materials dictate their conditions, forcing manufacturers to look for alternatives.

Consider the evolution of copper content depending on the decade of production:

• 📅 1970–1990: Models of this period (often with enamel coating) contained the maximum amount of copper. The piping was thick-walled and the condensers were all copper coils. The weight of copper could reach 2 kg or more.
• 📅 1990–2005: The period of transition to new refrigerants. steel is in the circuit, but copper still dominates in critical areas. The weight of copper is reduced to 1–1.5 kg.
• 📅 2005–2015: Active introduction of aluminum alloys in evaporators. The copper remains mainly in the discharge tube and part of the condenser. The total weight drops to 0.5–0.8 kg.
• 📅 2015–present: Use of composite materials and copper-plated steel. Pure copper is found only in connections and short sections of compressor tubes.

You can determine the year of manufacture by the serial number located on the nameplate inside the chamber or on the back wall. The first two digits of the code often indicate the year, although the marking has varied. If you see a heavy, massive capacitor at the back, the likelihood of high copper content is high. If the grille is light and magnetic, it is steel. Minsk Refrigerator Plant changed. If you see a heavy, massive capacitor at the back, the likelihood of high copper content is high. If the grille is light and magnetic, it is steel.

How to distinguish copper from steel without chemicals?

Copper has a characteristic reddish-golden color when cut and is not magnetic. The steel is silver and magnetic. Brass and bronze (copper alloys) may have a yellow tint, but refrigerators use almost pure M1 or M2 copper.

Table of copper content in different models

For clarity, we present average data on copper content in popular series of refrigerators Atlant. These data are based on statistics from recycling centers and records from service technicians. It should be understood that a specific modification may differ from the table due to changes in design within the same model range.

As can be seen from the table, the difference is the content of non-ferrous metal can be double. This directly affects the cost of scrap sold. If you are planning to scrap a refrigerator, it makes sense to evaluate its model and year of manufacture in advance in order to understand what price you can ask for it. Reception points They often lower the price if they cannot visually determine the contents, so knowing the characteristics of your unit will give an advantage in negotiations.

Replacement technologies: aluminum versus copper

Why are manufacturers, including Atlant, gradually abandoning copper in favor of aluminum and steel? The answer lies in economics and physics. Aluminum is cheaper, lighter and has good thermal conductivity, although it is inferior to copper in this parameter. However, to compensate for this disadvantage, it is enough to increase the heat exchange area, which is easy to do in modern compact designs.

Another factor is corrosion. Aluminum forms an oxide film that protects it from further deterioration, but it is more susceptible to galvanic corrosion where it joins other metals. This is why leaks often occur at the junction of copper and aluminum pipes. In modern refrigerators, they try to avoid such joints, using either an all-aluminum circuit or special adapters.

Steel, in turn, is stronger and cheaper than both non-ferrous metals. Stainless steel or alloy steel pipes can withstand higher pressures, allowing the use of new types of refrigerants. However, steel requires more powerful compressors to pump the gas, which can affect energy consumption. Engineers find a balance between the cost of materials and the efficiency of the entire system.

⚠️ Attention: If you are doing repairs and replacing a section of tube, never connect copper and aluminum with simple twisting. Use only special adapters (“collets”) or soldering using flux for aluminum, otherwise the joint will quickly oxidize and leak.

Removal process and safety

If you decide to dismantle copper elements yourself, you will need a set of tools: a pipe cutter, pliers, safety glasses and gloves. The process begins by disconnecting the device from the network and defrosting. Then the back panel is removed (if the condenser is external) or the walls are carefully opened (which is rarely justified economically).

The pipelines are cut or sawed through. It is important not to damage the compressor unless you plan to scrap the whole thing. Copper tubing is often coated with black enamel or insulation, which must be cleaned before weighing because collection points may deduct the weight of contaminants. The compressor is sold separately as “electric motor scrap” or “heavy scrap”, where the price per kilogram is lower than for pure copper.

• 🛠️ Tools: Pliers for radiators, a hacksaw for metal, safety glasses.
• 🧤 Protection: Thick gloves (metal can have sharp edges), a respirator (when burning insulation, although this is prohibited).
• ♻️ Sorting: Separate brass (yellow) from pure copper (red), as they are accepted at different prices.

Do not forget about the environmental side of the issue. The refrigerants contained in the system (freon R134a, R600a), when released into the atmosphere, contribute to the destruction of the ozone layer or are greenhouse gases. Isobutane (R600a), used in many modern Atlant models, is also explosive when mixed with air in a certain concentration.

Economic feasibility of disposal

Is the game worth the candle? To answer this question, you need to compare the potential income from copper donation with the time and effort required. The price of scrap copper fluctuates, but is usually significantly higher than the price of ferrous scrap or aluminum. However, given that there is not much copper in one refrigerator, you need to collect dozens of them to get a tangible amount.

It is often more profitable to hand over the entire refrigerator as household scrap. In this case, processors themselves separate the materials using industrial shredders and separators. This frees you from the dirty work and risks associated with gases. In addition, many appliance stores offer a discount on a new refrigerator when you turn in an old one, which can be more cost-effective than selling for scrap.

However, for owners of service centers or repair shops where old refrigerators accumulate during the process, sorting copper becomes a way to obtain additional funds for the purchase of spare parts. On the scale of one device, the profit can amount to several dollars, but on the scale of a month of work in a workshop, this is already a significant amount.

Frequently asked questions (FAQ)

Is it possible to return the entire refrigerator without disassembling it?

Yes, most scrap metal collection points accept entire household appliances. However, the price per kilogram in this case will be lower, since the receiver will make a discount on the “clog” (plastic, glass, steel). Whether this is profitable or not depends on the current prices in your region.

Where is copper located in the compressor of the Atlant refrigerator?

In the compressor, copper is located in the windings of the electric motor. To get it, you need to cut the body, remove the “glass” with the motor and burn or chemically remove the varnish from the windings. Doing this at home is difficult and harmful to health.

Does the type of refrigerant affect the amount of copper?

Indirectly. The switch to low pressure refrigerants (R600a) allowed the use of thinner tubes, which reduced overall metal consumption. High-pressure refrigerants required thicker-walled pipes, where there was more copper.

Are copper pipes with oil residues accepted?

Most likely they will be accepted, but with a deduction of the weight of contaminants (shrinkage) or at a lower price in the “mix” category. It is recommended to let the tubes drain or wipe them before handing them over.
