When planning the removal of old equipment or preparing for repairs, the question often arises about the actual weight of the unit. The weight of the refrigerator on metal — This is not just an abstract number, but an important economic and logistical parameter that influences disposal costs and relocation efforts. Many people mistakenly believe that the old Soviet unit and the modern one No Frost weigh the same, but the difference can be tens of kilograms.
In this article we will look at what the mass of the case is made up of, why it changes depending on the year of manufacture and how to correctly estimate the amount of useful metal. Understanding these nuances will help you not to become a victim of unscrupulous receivers or, conversely, not to undercut the price when handing over equipment.
Knowing the exact mass is necessary for calculating the load on the floor during installation, planning the lifting capacity of the elevator and assessing the profitability of dismantling. Let's take a closer look at the factors that form the final weight.
Factors influencing the total weight of the unit
The first thing that determines how much a refrigerator weighs is the dimensions and volume of the internal chambers. Obviously, a two-meter model Indesit will be significantly heavier than a compact minibar installed in a hotel. However, a linear relationship is not always traced here, since the wall thickness and density of insulating materials play an important role.
The second critical factor is the type of compressor and the number of motors. Older models were often equipped with heavy cast iron compressors, while modern inverter motors are made of lighter alloys, but can have greater weight due to complex electronics and copper windings. Compressor weight makes up a significant proportion of the total weight.
⚠️ Attention: The weight of the unit may differ from the passport data by 5-10% due to ice accumulated inside, oil in the system or dust in the condenser.
The third aspect is the material of the shelves and interior decoration. Glass shelves Tempered Glass weigh significantly more than plastic grilles, and the presence of a massive metal back panel also adds kilograms. In modern models, manufacturers strive to lighten the design, replacing metal with plastic where safety allows.
Design features: metal versus plastic
When analyzing how much metal is in the refrigerator, one cannot ignore the evolution of materials. In Soviet times, the body and internal elements were made primarily of steel. The doors, back wall and even some internal partitions were metal, which made the equipment incredibly durable, but extremely heavy.
Modern manufacturers actively use ABS plastic and polystyrene for internal chambers. This reduces overall weight, makes it easier to form complex geometries and reduces thermal conductivity. However, the outer contour is still made of sheet steel coated with enamel or varnish to ensure structural rigidity and the magnetic properties of the door.
It is important to note the difference in thermal insulation. In the past, fiberglass or thicker layers of low-density polyurethane foam were used. Modern models have a thin but highly effective layer of insulation, which makes it possible to make the walls thinner without losing the quality of cooling, indirectly affecting the overall weight.
- 🏗️ External casing: Sheet steel 0.5-0.8 mm thick makes up the bulk of ferrous metal.
- ❄️ Evaporator and condenser: In old models - steel and aluminum, in new ones - mainly aluminum and copper.
- 🧱 Insulation: Polyurethane foam, which has practically no weight compared to metal, but takes up volume.
Average weight of refrigerators of different types and sizes
To understand how much a metal refrigerator weighs, it is most convenient to classify equipment by size. The data are averaged, since a specific model Liebherr or Bosch may have unique material density characteristics.
Small refrigerators, often used in offices or dorm-rooms, usually weigh from 20 to 35 kg. These are lightweight designs with a single compressor and minimal insulation. They are easy to transport in a passenger car, and they contain the least amount of non-ferrous metals.
The middle class, represented by standard two-chamber models with a height of 160-180 cm, has a weight in the range of 50-70 kg. This is the most common segment where the balance between capacity and weight is optimized for the mass consumer.
| Refrigerator type | Height (cm) | Average weight (kg) | Base metal |
|---|---|---|---|
| Minibar | 50-85 | 20-30 | Steel, Aluminum |
| Medium (2 chambers) | 150-180 | 50-70 | Steel, Copper |
| High (Side-by-Side) | 190-210 | 90-120 | Steel, Copper |
| Soviet (3-chamber) | 170-200 | 80-100+ | Steel (thick) |
Large models such as Side-by-Side or American refrigerators can reach a weight of 120 kg or more. They are equipped with two compressors, ice generation systems and massive doors, which significantly increases the load on the floors and the difficulty of moving.
Disassembly: how many kg of non-ferrous and ferrous metal
For those who are considering handing over equipment to collection points, it is important to understand the difference between the total weight and the weight of useful scrap. Ferrous metal (hull steel) is about 70-80% of the total mass. This is what remains after rough cutting and removal of the plastic.
The most valuable component is non-ferrous metal. Refrigerators contain copper (in the condenser and evaporator tubes, compressor windings) and aluminum. In older models (ZIL, Biryusa until the 90s), the tubes were often made of steel, which reduces their value, but increases the overall weight.
⚠️ Attention: In modern refrigerators, tubes can be made of aluminum or even copper-plated steel, which reduces the yield of pure copper during processing.
The compressor is the “heart” and source of non-ferrous metal. Inside it is a winding made of copper, and the body itself is often made of steel. On average, one compressor produces from 1 to 2 kg of pure copper after disassembly, not counting the steel case.
How much copper is in a compressor?
The average refrigerator compressor contains from 100 to 300 grams of pure copper winding. However, extraction requires cutting the body and the presence of tools, which is not always cost-effective when delivering small batches.
Comparison of the weight of old and modern models
Comparing equipment from different eras, one can notice a tendency to reduce weight while maintaining or increasing the useful volume. Soviet refrigerators were famous for their “indestructibility” and weight. The case steel there could reach 1 mm or more, and the doors closed with a characteristic heavy click.
Modern models, such as Samsung or LG, use high-strength, but thin grades of steel and composite materials. This allows us to reduce metal consumption during production and facilitate logistics. However, this also makes them more vulnerable to mechanical damage during transportation.
An interesting fact is that the weight of the cooling system in older models was greater due to the use of steel tubes, but less in terms of valuable copper content. Modern units contain more copper and aluminum in proportion to the total mass, despite the general trend towards lighter weight.
- 🕰️ Soviet classics: Heavy, bulky, a lot of steel, minimum electronics, easy to repair.
- 💻 Modern technology: Lighter, more plastic, complex control electronics, high energy efficiency.
- ⚖️ Weight difference: A modern analogue of the old three-chamber giant will be lighter by about 15-20%.
☑️ Assessment before scrapping
How to properly weigh and prepare for delivery
If you plan to hand over the refrigerator, you need to know its exact weight for a preliminary cost calculation. The easiest way is to find the data sheet or specifications sticker, which is usually located inside the camera or on the back wall. The net weight is indicated there, which most accurately reflects the weight of the device itself.
For weighing at home, you can use floor scales if the refrigerator can be tilted. Step on the scale with the cooler in your arms (or shoulder), write down the result, then weigh yourself without it. The difference will be the desired value. This method gives an error, but is quite acceptable for domestic needs.
When preparing to hand over metal to a collection point, it is necessary to remove all non-metallic elements that can reduce the price or be accepted as garbage. Remove plastic shelves, drawers, rubber seals and glass inserts. This will also make loading easier.
Be sure to ensure safety before handing over: cut the refrigerant pipes in a well-ventilated area, as gas may remain inside. Although freon is not flammable, its concentration in a confined space is undesirable.
⚠️ Attention: Scrap prices and acceptance rules may change. Check the current tariffs for non-ferrous metals and requirements for the preparation of equipment at your collection point immediately before delivery.
