When an old refrigerator stops working or completely fails, the owner inevitably faces The question arises of recycling large household appliances. The most valuable and heaviest part of the unit is its “heart” - compressor unit. It is this unit that contains a large amount of non-ferrous metal, which makes it an object of interest not only for recycling collection points, but also for DIY craftsmen.
You cannot simply throw the equipment at the nearest container site, as this violates environmental standards and rules for urban improvement. The compressor contains oil and refrigerant which, if the housing ruptures, can be harmful to the environment. Therefore, it is important to know where to put the compressor from the refrigerator in order to get money for it or at least sell it legally.
In this article we will analyze in detail all possible ways to solve the problem: from scrap metal to use for economic purposes. You will learn how to correctly assess the weight and value of a part, as well as what safety measures must be taken during dismantling.
Assessing the value and weight of a compressor
Before taking the part to the collection point, it is worth understanding what exactly you are handing over. The compressor is a sealed unit containing copper motor windings and steel plates. It is impossible to determine the amount of copper by eye, since the body is sealed, but experienced inspectors know the approximate yield of metal.
The weight of a standard household compressor varies from 8 to 12 kilograms. However, when selling scrap metal, a dispute often arises: to consider it as ferrous scrap (steel) or as scrap containing non-ferrous metals. Copper winding makes up a significant part of the cost, but in order to get the full price for it, the case often needs to be opened, which is difficult and dangerous at home.
The cost depends on the current quotes on stock exchanges and the policies of a specific collection point. Typically, compressors are accepted at the price of ferrous metal with a small premium or at a reduced price for non-ferrous scrap, if the housing is not opened. In any case, this is more profitable than just leaving the part lying in the garage.
Important to consider: Old Soviet models may contain more copper than modern Chinese counterparts, where manufacturers often save on winding materials by using aluminum instead of copper.
⚠️ Attention: Never try to open the sealed compressor housing yourself grinder or hacksaw without first removing freon! There may be gas under pressure inside, and oil and refrigerant vapors are toxic.
Delivering to scrap metal collection points
The most obvious and common option is to hand over the compressor to the nearest metal collection point. This solution allows you not only to free up space, but also to receive a small monetary compensation. Most organizations accept household appliances and their components without restrictions.
When handing over, it is important to take into account the condition of the part. If the compressor is intact, not deformed and not filled with water, it will be more readily accepted. Some items require the removal of the start relay and filter drier, as they may contain additional non-ferrous metals, which are handed over separately.
For those who have accumulated several pieces of equipment, it may be more profitable to call a specialized disposal service. They will take the entire refrigerator, but most likely they will not pay money for it; on the contrary, they may charge a fee for removal if the equipment is located far from the base.
- 🏭 Find the nearest collection point through maps or a directory.
- ⚖️ Weigh the compressor at home to approximately know the weight.
- 💰 Check by phone whether they accept sealed units separately.
- 🚛 Solve the delivery issue: on your own or by ordering loaders.
If you plan to deliver several compressors at once, it makes sense to agree on the price in advance. Large lots are always of more interest to receivers, and bargaining is possible here. However, it is worth remembering that scrap prices are floating and can change daily.
Use for household purposes and DIY
If handing over metal seems too troublesome or profitable to you, consider using a compressor at home. An old but working unit can get a “second life” in the hands of a home craftsman. Many craftsmen convert them into compressors for inflating tires, airbrushing or pneumatic tools.
To create a homemade compressor (the so-called “receiver”) you will need a minimum set of tools and skills. The main advantage of such devices is the low noise level compared to industrial analogues and the ability to create sufficient pressure for domestic needs.
However, if the compressor is not working (the winding is burned out or the piston is jammed), it can still be disassembled. The recovered copper, steel and even oil (after filtration) can be useful in the workshop. Copper wire is handed over separately, and the housing is used as a load or a base for other structures.
☑️ Checking the compressor before reworking
When reworking, it is important to follow safety precautions. It is necessary to install a receiver (air cylinder), pressure gauge and pressure relief valve. Without these elements, the device can become dangerous, since a household compressor is not designed for continuous operation under high pressure.
Can a refrigerator compressor be used as a vacuum pump?
Yes, this is possible, but with limitations. The compressor can pump out air, creating a vacuum, but the performance will be low. For serious tasks, it is better to use specialized pumps, but for simple experiments or vacuuming packaging, an old unit is also suitable.
Safe dismantling of the unit
If you decide to remove the compressor yourself, you need to prepare for the process. The work involves electricity, metal and possible refrigerant residues. The first step should always be to disconnect the device from the power supply.
For dismantling you will need a set of tools: wrenches, screwdrivers, wire cutters and possibly a hacksaw. The tubes connecting to the compressor are most often copper and thin; they can be cut, but this must be done carefully so as not to damage other components if you plan to hand over the entire refrigerator.
Before disconnecting the tubes, make sure that there is no pressure in the system. If the refrigerator has been running recently, the pressure may be high. Pierce the tube in a well-ventilated area, away from open fire, since freon forms toxic compounds when in contact with a flame.
After removing the tubes, unscrew the mounting bolts or nuts holding the compressor to the frame. Often it is mounted on rubber shock absorbers, which will need to be carefully removed or cut. Don't forget to disconnect the electrical wires going to the start relay.
| Tool | Purpose | Precautions |
|---|---|---|
| Pliers | Cutting copper pipes | Keep your eyes away from chips |
| Wrench | Unscrewing the frame fasteners | Check the size so as not to tear off the edges |
| Screwdriver | Removal clamps and wires | Make sure there is no voltage |
| Gloves | Hand protection | Use thick work gloves |
⚠️ Attention: The oil leaking from the compressor is technical and toxic. Do not pour it down the drain or onto the ground. Collect it in a sealed container and take it to a hazardous waste collection point.
Legal aspects of disposal
The issue of disposal of household appliances is regulated by environmental protection legislation. Throwing refrigerators and their components into regular trash cans is prohibited, as they belong to the class of waste that requires special processing.
For improper disposal of large scrap items, fines may be imposed on individuals, although in practice this rarely happens unless you throw away the equipment in the forest or at someone else's container. However, responsibility lies with the owner of the equipment until it is transferred to a specialized organization.
There are recycling programs from hardware stores. When you buy a new refrigerator, you can trade in your old one at a discount. In this case, the store takes care of all transportation and recycling issues, including the compressor.
If you hand over the compressor to a private collection point, make sure that the organization has a license to work with scrap. This ensures that the metal is not simply melted down in a garage in violation of environmental standards, but sent to the correct plant.
Alternative options: sale and exchange
If the compressor is in working order and is a rare model, you can try to sell it. On message boards people often look for spare parts for repairing certain brands of refrigerators, especially if the original spare parts are no longer in production or are expensive.
Home appliance repair shops may also be interested in used units. For them, this is an opportunity to cheaply restore customers’ equipment. Contact local services and offer your option, indicating the model of the refrigerator and the condition of the compressor.
Another option is exchange. Some forums and communities of radio amateurs conduct barter. You can exchange the compressor for other parts or tools that you need for other projects.
When selling, be sure to indicate whether the compressor was removed from a working refrigerator. If the device has simply been lying in a garage for 10 years, its condition may be unsatisfactory due to oxidation of contacts or thickening of the oil.
Frequently asked questions (FAQ)
How much does a refrigerator compressor weigh without oil?
The weight of the compressor practically does not change after draining the oil, since there is only about 200-300 grams. The total weight of the unit is on average 9-11 kg. When scrapped, the scales will show the mass along with the remaining oil; no one will drain it before weighing.
Is it possible to throw the compressor into a regular garbage chute?
It is absolutely not possible. The compressor is a large metal object that will get stuck in the garbage disposal or damage the garbage truck. In addition, this is a violation of the rules of operation of a residential building and environmental standards.
What to do if black oil leaks from the compressor?
Black oil is a wear product of the compressor; it contains combustion products of insulation and metal shavings. This oil cannot be reused. It must be collected in containers and handed over as hazardous waste, and not poured down the sink.
Will they accept a compressor if it is broken or sawn?
Yes, metal collection points accept scrap in any form. However, if you cut it yourself, the receiver may classify it as a “mixu” (a mixture of metals) and pay at a lower price than for a whole assembly where the copper winding is visible.
Is there gold or silver in the compressor?
In household compressors there are no precious metals in industrial quantities. The contacts may be plated with silver, but the amount is so minute that extraction is not economically feasible. The main value is copper and steel.
