Old Soviet refrigerators, such as the legendary ZILare still found in many garages, dachas and basements of country houses. Owners often wonder whether they can get a real monetary benefit from them by selling them for scrap, or whether there are rarer components hidden inside that are of interest to collectors and craftsmen. In an era when equipment was created to last for centuries, engineers did not skimp on materials, which makes disassembling such units a potentially profitable activity if you know what exactly to pay attention to.
Unlike modern plastic analogues, the design ZIL refrigerator involves the use of a significant amount of heavy metals, high-quality steel and reliable electromechanical nodes Understanding the value of individual components allows you not only to hand over the unit by weight, but to get the maximum profit from its disposal or restoration. Next, we will analyze in detail which elements are of the greatest interest.
Analysis of the motor-compressor - the heart of the unit
The most valuable and heaviest component in any refrigerator is motor-compressor. In ZIL models, especially in early years of production, sealed units were installed, the weight of which could reach 10–12 kilograms. The main value here is the copper winding of the electric motor and the steel plates of the housing. It is copper that is the target metal for those who accept non-ferrous scrap, although it is extremely difficult to extract it from there in its pure form without professional equipment.
Many craftsmen involved in the repair of retro equipment are hunting for serviceable ZIL compressors for installation in home-made products. Powerful motor copes perfectly with pumping air, water, or used to create compressors for airbrushing and painting work. If the compressor is in working condition, its value as a used spare part can be many times greater than the cost of the metal contained in it.
However, it is worth considering that old compressors often contain freon, which requires proper disposal. When scrapped, such units may be valued lower if the collection point does not have a license to work with refrigerants. Therefore, before dismantling, you must make sure that there is no pressure in the system.
⚠️ Attention: Never try to open the sealed compressor casing with an angle grinder or fire. There may be liquefied gas under pressure inside, which can lead to an explosion and scattering of fragments.
How to determine the type of compressor
The ZIL compressor nameplate usually indicates the series. If there are the letters “KSh”, this means a refrigeration compressor. Models with the "M" index often had increased power, which made them more valuable for secondary use in workshops.
Condenser and radiator: where to look for non-ferrous metal
The rear grille of the refrigerator, known as condenser, is a system of tubes through which refrigerant circulates. In Soviet ZIL models, steel was often used for the manufacture of these tubes and radiator fins, but in some modifications and connecting elements it was found copper and aluminium. Aluminum radiators are valued slightly higher than steel, but significantly lower than copper.
When dismantling, it is important to carefully disconnect the radiator from the body so as not to damage the tubes if you plan to sell it as a single unit. However, to maximize profits from scrapping, separation of materials is most often required. Steel goes at the same price, and non-ferrous metals go at a much higher price. Disassembly takes time, but it pays off.
It is also worth paying attention to the evaporator inside the chamber. In older models it could be made of aluminum or stainless steel. If the evaporator is aluminum, its weight can be several kilograms of pure metal, which is already a noticeable bonus when recycling.
- 🔩 Steel coil - sold as black scrap, requires large volumes for profit.
- 🔶 Copper connections - high value, found at the joints of tubes.
- ⚪ Aluminum plates - middle price segment, easy to distinguish by weight and magnet.
The body and internal filling
External refrigerator body ZIL is made of sheet steel coated with enamel. Such a unit weighs a lot, often exceeding 50–60 kilograms. When delivered entirely as ferrous scrap, the revenue will be minimal, since the volumetric weight is not always taken into account in full. However, Soviet-made steel was of high quality and thickness, which makes it suitable for reuse for household purposes.
The inside of the chamber is also metal. Unlike modern plastic inserts, here you will find durable stainless or enameled steel. The refrigerator doors contain a magnetic seal, which in itself is not valuable, but the steel door lining adds to the total weight of the metal being handed over.
Shelves and drawers in ZIL could be made of metal or durable plastic. Metal grating shelves can be returned along with the housing. Plastic elements, if they are not marked as recyclable, are most often sent to landfill, since their disposal is unprofitable.
| Component | Basic material | Approximate weight | Liquidity |
|---|---|---|---|
| Compressor | Steel, Copper | 10-12 kg | High |
| Radiator (condenser) | Steel/Aluminium | 3-5 kg | Medium |
| Case | Sheet steel | 40-50 kg | Low |
| Electrical | Copper, Plastic | 0.5-1 kg | Average |
Electrical circuit and wiring
Electrical wiring in ZIL refrigerators are made with a safety margin. The copper wires running from the compressor to the thermostat and start relay have thick insulation and high-quality copper core. Although the total weight of copper here is small (usually 200–400 grams), it is extracted separately, since the price for copper wire is significantly higher than for mixed scrap.
The control unit, thermostat and start relay contain small amounts of non-ferrous metals. The start relay often contains copper contacts, which are of interest to radio amateurs. The thermostat is a complex mechanical-thermal assembly that can be useful for repairing other refrigerators if it is working properly.
When disassembling the electrical system, it is important to be careful, since the capacitors in the circuit could retain a residual charge, although this is rare in older models. The main task is to carefully bite out the wires without damaging the insulation, if you plan to sell them as is, or strip them for delivery of pure copper.
☑️ Disassembling the electrics
Thermal insulation: polyurethane foam or fiberglass
Between the outer and inner casing of the ZIL refrigerator there is a layer thermal insulation. In earlier models, this could be fiberglass (glass wool), which settles and loses its properties over time. In later Soviet and post-Soviet models, polyurethane foam was used, which tightly fills the space.
From the point of view of value, thermal insulation material is not of interest for delivery. On the contrary, it is a disposal problem because it increases the volume and weight of the unit without adding value. When disassembling to obtain metals, the thermal insulation has to be broken out or cut out, which creates a lot of dust and debris.
⚠️ Attention: Old glass wool in thermal insulation irritates the skin and respiratory tract. When disassembling such models, be sure to use a respirator, safety glasses and thick long sleeves.
If you plan to rent out the entire refrigerator, the presence of thermal insulation does not affect the price, since the total weight is weighed. But if you want to get pure metal, you will have to work hard to clean the parts from adhering foam or cotton wool.
Collectible value and retro style
Do not discount and collectible value. ZIL refrigerators, especially in original condition, with a preserved emblem, intact handles and working internal light, are in demand among interior decorators in loft, retro or Soviet modern style. Cafes, bars and museums often look for such equipment to create atmosphere.
If your unit has a rare color (for example, cream, blue or green, rather than the standard white), its chances of becoming an exhibit increase. In this case, dismantling for scrap would be a grave mistake. Restoring the appearance and selling it as a piece of furniture can bring in income tens of times higher than the cost of scrap.
The key factors here are: the integrity of the enamel, a working compressor (or the possibility of its quiet operation), the presence of original shelves and handles. The presence of an original nameplate with the serial number and production date significantly increases the collection value copy.
- 🎨 Original emblem - increases the price for collectors.
- 🔊 Quiet operation - a rarity for old models, very much appreciated.
- 🔑 Set of keys - if the lock on the door is still there, this is a big plus.
Frequently asked questions (FAQ)
Approximately how much does it cost to scrap a ZIL refrigerator?
The price depends on the current exchange rate for metals and the weight of the unit. Typically an old refrigerator weighs 50-60 kg. If you sell it as scrap, the amount will be small. If you manage to dismantle and sell copper and aluminum separately, revenue will increase, but it will require time and effort.
Is it possible to use a compressor from ZIL for other purposes?
Yes, compressors from ZIL are often used to create homemade compressors for inflating tires, aerography, or supplying air to aquariums. The main thing is to make sure that they are in good working order and that there are no short circuits in the windings.
Where can I find the electrical circuit diagram for the ZIL refrigerator?
The circuits were often glued to the inner wall of the case or were in the product passport. Also, electrical diagrams of popular Soviet models can be found in specialized archives and on forums for repairing household appliances.
Is freon in an old refrigerator dangerous?
The freon used in Soviet times (R12) itself is not toxic when inhaled in small quantities, but it is heavier than air and can displace oxygen. In addition, upon contact with an open flame, it can form toxic compounds. Simply releasing it into the atmosphere is not recommended for environmental reasons.
