What kind of freon is in the Atlant refrigerator: types of refrigerants and correspondence table

Owners of household appliances are often faced with the need to find out the exact brand of refrigerant when the unit stops freezing or requires scheduled maintenance. For the Belarusian brand Atlant this issue is especially relevant, since the manufacturer has been producing models for several decades using different types of gases. Understanding what kind of freon is poured into your system is critical for safe and effective repairs.

The wrong choice of refrigerant can lead to compressor failure or even create an emergency situation, especially considering that modern gases can be flammable. In this article, we will analyze in detail the differences between R600a and R134a, learn how to read the nameplate and find out how not to make mistakes when ordering the services of a specialist or purchasing spare parts.

It is important to immediately note that there is no universal answer: the type of gas depends on the year of manufacture and the specific series of the refrigerator. Old Soviet models and early versions of Atlants could contain R12 freon, which is now prohibited, while modern units operate on environmentally friendly analogues. Let's look at the details so that you can competently approach the solution to the problem.

Main types of refrigerants in Atlant refrigerators

Historically, several generations of refrigerants were used in refrigeration equipment. In technology Atlant you can most often find three main types, each of which has its own chemical and physical properties. Isobutane (R600a) today is the standard for most new models due to its environmental friendliness and high efficiency, but it requires special care when working.

The predecessor of isobutane was tetrafluoroethane (R134a), which was widely used in models released in the 2000s and early 2010s. It is safer for humans than older freons, but less efficient than modern analogues and requires the use of synthetic oil. There are also rare cases of using mixtures, but they are more typical for industrial equipment or very specific series.

⚠️ Attention: Isobutane (R600a) is a flammable gas. Any work related to depressurization of the system should be carried out only by professionals in a well-ventilated area, away from sources of open flame.

It is strictly forbidden to mix different types of freon. If the system had R134a, refilling R600a is unacceptable without completely flushing the circuit and changing the oil, as this will lead to a chemical reaction and the formation of acids that destroy the compressor from the inside. Accurate knowledge of the gas brand is the first condition for successful repairs, without which the master has no right to start work.

How to determine the type of freon from the nameplate and documentation

The most reliable way to find out what yours is filled with Atlant refrigerator is to find a technical passport or sticker on the case. Typically, the manufacturer places a metal plate or paper sticker with technical information on the back wall of the unit, sometimes on the inside wall of the refrigerator compartment or on the end of the door. Look for the field labeled “Refrigerant” or “Refrigerant.”

If the sticker is worn off or lost, you can refer to the year of manufacture. Models produced before 2000 most often used R12; from 2000 to 2010, R134a was actively introduced, and after 2010 isobutane became dominant. However, this rule has many exceptions, so a visual inspection of the compressor can also give clues: technical specifications are often stamped on the motor casing.

The documentation always indicates not only the type of gas, but also its exact mass in grams. This is a critically important parameter, since modern systems are sensitive to overdosing or underfilling. Refilling Even 10-15 grams can cause the refrigerator to work intermittently or not turn off at all.

Comparison table: R600a versus R134a

Understanding the difference between the two main types of gases used in technology Atlanthelps to better understand the requirements for repair and operation. R600a (isobutane) and R134a (tetrafluoroethane) are not just different names, they are fundamentally different substances with excellent thermodynamics.

R600a has better cooling performance and requires less substance to fill the system, which makes it economical. However, its flammability imposes strict restrictions on soldering and vacuum methods. R134a is inert and safe in terms of ignition, but requires more powerful compressors and larger tube diameters for effective operation.

Pay attention to the type of oil in the table: this is a key point when replacing the compressor. If you change the engine to Atlanta with R134a, you cannot use a compressor designed for mineral oil without completely flushing the system, since synthetics and mineral water do not mix. Oil incompatibility is a common cause of repeated breakdowns after a seemingly successful repair.

⚠️ Attention: The pressure in the system with R600a is below atmospheric when the compressor is stopped. This means that during depressurization, air and moisture can get inside, which will lead to the formation of ice jams and acids.

Features of operation of old and new models

Refrigerators Atlant, released in different years, require different approaches to maintenance. Old models running on R12 are almost out of order or have been rebuilt, but if you still have such a unit, it will be difficult to find gas for it due to the ban on the production of R12. In such cases, craftsmen often offer adaptation to R134a, which is a complex procedure.

Modern models running on isobutaneare quieter and consume less electricity. However, their pipelines are often made of thin-walled aluminum or steel, making them vulnerable to corrosion and mechanical damage. Careful handling of the evaporator inside the chamber is the key to the long life of such a refrigerator.

If your refrigerator was produced during the transition period (about 2005-2008), there is confusion in the markings. At this time, the plant could use remnants of old components or experiment with new ones. Therefore, relying only on the year of manufacture in this range is risky.

Leakage symptoms and the need for refilling

How can you tell if freon has left the system? The first sign is a decrease in the quality of freezing or its complete absence. The compressor may run continuously, trying to gain temperature, but no cold appears. In models with No Frost warm air may blow, but there will be no frost on the back wall.

Another symptom is swelling of the side walls of the refrigerator (in models with a foamed evaporator) or the appearance of rust at the leak site. If you notice an oily spot under the refrigerator or on the pipes at the back, this is a sure sign of depressurization, since freon circulates along with the oil.

• 🔇 The compressor works constantly or turns on very rarely, without reaching the desired temperature.
• ❄️ In the freezer, food is defrosted, in the refrigerator - the temperature is higher than normal.
• 💧 The appearance of condensation, puddles or swelling on the body.
• 👃 The appearance of a specific odor (although freon itself is often odorless, burnt oil or food may smell).

Trying to simply “add” gas without searching and fixing a leak is a futile exercise. Freon does not disappear anywhere on its own in a working system; if it is not there, then there is a hole. Searching for leaks - a mandatory repair step, which often costs more than the refill itself.

⚠️ Attention: Do not try to solder the tubes yourself or add gas from a can “for car air conditioners.” The pressure and types of gases in automotive and household systems are radically different, which will lead to a compressor explosion.

Refilling process: what the owner needs to know

The process of refilling a refrigerator Atlant with freon is a high-tech procedure that requires specialized equipment: a vacuum pump, a pressure gauge stations and electronic scales. First, the technician must find the leak, solder it and pressurize the system with nitrogen to check the tightness.

Then follows the vacuum stage. This is a critical point, especially for systems with R600a. It is necessary to remove all air and moisture from the circuit, since even a microscopic amount of moisture will freeze in the capillary tube and block the circulation of gas. Evacuation should last at least 30-40 minutes.

Only after this is refueling performed strictly according to the weight indicated on the nameplate. The use of “eye-measuring” methods or refilling to a certain pressure in domestic refrigerators is unacceptable, since the pressure depends on the ambient temperature and the load on the compressor.
