Refrigerators Atlant are one of the most popular in the post-Soviet space due to their reliability and affordable price. But even the highest quality equipment requires maintenance, especially when it comes to refrigerant the substance that ensures the cooling of the chambers. If your refrigerator freezes worse, an unpleasant odor appears, or the compressor works without stopping, the problem may lie in freon.
Many users do not know what refrigerant is used in their model, how to check it and what to do if there is a leak. In this article we will analyze all types of freons used in refrigerators Atlant, their features, pros and cons, and also give practical advice on diagnostics and replacement. We will pay special attention safety because some refrigerants are flammable, while others require special conditions for refilling.
If you are planning a DIY repair, it is important to understand: working with freon is not only a technical process, but also an environmental issue. Improper disposal or refilling may be harmful to the environment and your health. Therefore, before any manipulations, read the instructions and, if necessary, contact professionals.
What refrigerants are used in Atlant refrigerators
The Belarusian manufacturer Atlant uses two main types of freons in its refrigerators: R134a and R600a. The choice of refrigerant depends on the model, year of manufacture and technical characteristics of the device. Let's take a closer look at each of them.
R134a (tetrafluoroethane) is a synthetic refrigerant that has long been the standard for household appliances. It is non-toxic, non-explosive and non-flammable, making it safe for home use. However, from an environmental point of view, it is not ideal: R134a has a high global warming potential (GWP = 1430), so it is gradually are being replaced by more modern analogues. In refrigerators Atlant this freon is found in models released before 2010–2015, as well as in some budget series.
R600a (isobutane) is a natural hydrocarbon refrigerant, which today is considered one of the most environmentally friendly. Its GWP is only 3, which is hundreds of times less than that of R134a. Additionally, the R600a is more energy efficient, reducing your refrigerator's energy consumption by 10-15%. However, it has a significant disadvantage: isobutane flammable, so special care is required in case of leakage. In refrigerators Atlant R600a is used in most modern models, starting from 2015.
To find out exactly which refrigerant in your refrigerator, check:
- 📄 Technical passport —in the “Characteristics” or “Technical Data” section the type of freon is usually indicated.
- 🏷️ The sticker on the compressor —there may be a refrigerant marking (for example, “R600a” or “134a”).
- 🔍 Refrigerator model —you can use it to find information on the Internet or contact a service center Atlant.
⚠️ Attention: If your refrigerator does not have obvious refrigerant markings, do not try to determine its type by smell or external signs. Both freons - R134a and R600a - are colorless and almost odorless. For an accurate diagnosis, use a pressure gauge manifold or contact a specialist.
How to distinguish R134a from R600a: key differences
Although both refrigerants perform the same function - cooling the refrigerator chambers - their properties are very different. This affects not only operation, but also repairs. Below is a comparative table of the main characteristics:
| Parameter | R134a | R600a |
|---|---|---|
| Refrigerant type | Synthetic (HFC) | Natural (hydrocarbon) |
| Flammability | No | Yes (explosive at a concentration of 1.3–8.5%) |
| Toxicity | No | No (in small concentrations) |
| Energy efficiency | Average | High (10–15% more economical) |
| Impact on the ozone layer (ODP) | 0 | 0 |
| Global potential warming (GWP) | 1430 | 3 |
| System pressure (at 25°C) | ~1.1 bar (low) | ~0.3 bar (very low) |
The table shows that R600a wins in terms of environmental friendliness and energy efficiency, but loses in security. For example, if isobutane leaks indoors, an explosive mixture can form. However, in practice, this requires a very high concentration of gas (more than 31 g/m³), which is unlikely in domestic conditions.
Another important difference is pressure in the system. For R600a, it is significantly lower than for R134a, so its refilling requires special equipment with appropriate pressure gauges. If a technician accustomed to working with R134a tries to charge R600a without adjusting the pressure, this may lead to compressor failure.
Signs of a refrigerant leak in the Atlant refrigerator
Freon leakage is one of the most common malfunctions of refrigerators. It can occur due to tube corrosion, mechanical damage or manufacturing defects. The problem can be recognized by several characteristic signs:
- ❄️ The refrigerator does not cool or it freezes weakly, despite the compressor running.
- ⏳ The compressor works without stopping (no on/off cycles).
- 🔊 Extraneous sounds: hissing, gurgling or whistling due to escaping gas.
- 🧊 Ice on the back wall or in the freezer (a sign of a lack of refrigerant).
- 🤢 Unpleasant odor (rare, but possible if R600a leaks in large volumes).
If you notice at least one of these symptoms, you need to check the system for leaks. For this, technicians use:
- Electronic leak detector —a device that reacts to freon vapors.
- Soap solution —applied to suspected leak sites (bubbles will indicate a breakdown).
- Ultraviolet dye - is added to the system during refueling, and then detected using a UV lamp.
It is difficult to find a small leak on your own, especially if it is in the foamed part of the refrigerator. In such cases, professional diagnostics are required to depressurize the system.
⚠️ Attention: If the leak occurs in the freezer or near the electronics, do not try to repair the refrigerator yourself. Freon under pressure can damage the control boards, and in the case of R600a there is a risk of fire upon contact with sparks.
What to do if the freon has leaked completely?
If the refrigerant has leaked completely, the compressor will run "idle", which can lead to its overheating and failure. In this case it is necessary:
1. Disconnect the refrigerator from the network.
2. Do not turn it on until the leak is fixed and refilled.
3. Contact a service center, since self-refueling without experience is fraught with repeated leakage or compressor breakdown.
Is it possible to replace R134a with R600a and vice versa
This question often arises among owners of old refrigerators Atlantwho want to switch to a more environmentally friendly one refrigerant, or vice versa - when R600a is difficult to find in service centers. Theoretically, replacement is possible, but in practice it is associated with a number of difficulties.
Replacement of R134a with R600a:
- ✅ Pros: increased energy efficiency, less burden on the environment.
- ❌ Cons:
- The oil in the compressor needs to be changed (R600a works only with polyester oils, and R134a - with polyolester oils).
- It is necessary to flush the system from the remains of old freon and oil.
- It may be necessary to replace the filter drier and some seals.
Replacing R600a with R134a:
- ✅ Pros: a more accessible and widespread refrigerant, less risks when refilling.
- ❌ Cons:
- Reduced energy efficiency of the refrigerator.
- An oil change and flushing of the system will be required.
- There may be problems with the operation of the capillary tube due to different pressures refrigerants.
In most cases, replacing the refrigerant impracticalas the cost of work can exceed half the price of a new refrigerator. The exception is rare models for which the original freon is not available. In such situations, the technician can offer an alternative refrigerant with similar characteristics (for example, R433b instead of R600a).
How to refill an Atlant refrigerator with freon: step-by-step instructions
If you decide to refill the refrigerator yourself, remember: this is a complex procedure that requires special equipment and skills. Errors can lead to compressor failure or freon leakage. Below is a simplified refueling scheme, but we recommend entrusting this work to professionals.
Necessary equipment:
- 🔧 Pressure manifold (for R600a - with sensitive pressure gauges).
- 🧪 Cylinder with freon (strictly corresponding to the model refrigerator).
- 🔌 Vacuum pump (for pumping air out of the system).
- 🔍 Leak detector (electronic or soap solution).
- 🛠️ Set of keys for service ports.
Step-by-step process:
- Leak diagnostics. Find and repair the breakdown (solder or replace tubes).
- Evacuate the system. Connect a vacuum pump to the service port and pump out air and moisture for 15-30 minutes.
- Checking the tightness. Close the valve and watch the pressure: if it does not drop, the system is sealed.
- Freon charging. Connect the cylinder through the manifold and slowly fill refrigerant, monitoring the pressure.
- Checking operation. Turn on the refrigerator and make sure that the compressor turns on/off cyclically and the temperature in the chambers is normal.
For R600a critical do not refill the system — excess refrigerant can lead to compressor water hammer. The optimal amount of freon is usually indicated on the compressor nameplate or in the service manual.

⚠️ Attention: When working with R600a, avoid sparks and open flames. Charge refrigerant in a well-ventilated area or outdoors. If you are not confident in your skills, contact the service center - the cost of refilling from professionals (1500–3000 rubles) is significantly lower than the price of a new compressor (from 8000 rubles).
Safety when working with freon: what you need to know
Even if you don't plan to refill the refrigerator yourself, it's important to understand the risks associated with refrigerants. This is especially true R600awhich is widely used in modern models Atlant.
Basic safety rules:
- 🚫 Do not smoke and do not use open fire near the refrigerator if you suspect a leak of R600a.
- 🪟 Ventilate the room when refueling or repairing - isobutane is heavier than air and can accumulate below.
- 🧤 Use gloves - contact of liquid freon with skin can cause frostbite.
- 👃 Do not inhale vapors —high concentrations of freon can cause dizziness or suffocation.
- 🔧 Do not disassemble the refrigerator without unplugging and bleeding the freon (this must be done by a technician).
If freon vapor poisoning (which is unlikely in domestic conditions), the following symptoms may be observed:
- Headache and nausea.
- Difficulty breathing.
- Weakness or loss of consciousness (in severe cases).
In such a situation, it is necessary to immediately get fresh air and seek medical attention.
If the leak occurred in a refrigerator with R134athe risks are less, but caution is still required. This freon is not flammable, but in high concentrations it can displace oxygen, causing suffocation. In addition, when heated above 250°C, it decomposes to form toxic substances (hydrogen fluoride and phosgene).
Where to buy freon for the Atlant refrigerator and how much does it cost
You can purchase refrigerant for refilling the refrigerator in specialized stores or online. However, there are several nuances that are important to consider:
Where to buy:
- 🛒 Refrigeration equipment stores — here you can find original cylinders with R134a and R600a, as well as consumables (oil, filters).
- 🌍 Online sites (for example, AliExpress, “AllTools”, “220 Volt”) - convenient, but check the reputation of the seller.
- 🔧 Service centers - some workshops sell freon wholesale or retail.
Cost of freon (for 2026):
| Refrigerant | Cylinder volume | Price, rub. | Notes |
|---|---|---|---|
| R134a | 13.6 kg | 3500–5000 | Suitable for old Atlant models |
| R600a | 6.5 kg | 2800–4000 | For modern refrigerators (from 2015) |
| R600a | 0.5 kg (small cylinder) | 800–1200 | Convenient for one-time refilling |
When purchasing, pay attention to:
- 📌 Cylinder certification —it should be marked with the name of the refrigerant, weight and date of inspection.
- 🔄 Possibility of return —some sellers do not accept return gas cylinders.
- 🚚 Delivery conditions — freon is classified as dangerous goods, so courier services may refuse to transport it.
⚠️ Attention: Prices for freon can vary greatly depending on the region and supplier. Before purchasing, check whether the selected refrigerant is suitable for your refrigerator model Atlant. In some cases, not pure R600a may be required, but its mixture with other substances (for example, R433b).
Frequently asked questions about freon in Atlant refrigerators
Is it possible to mix R134a and R600a in one refrigerator?
No, mixing these refrigerants is strictly prohibited. They have different physical and chemical properties, pressure and compatibility with compressor oils. The mixture can lead to compressor failure or leakage. If freon replacement is required, the system must be completely cleaned of old refrigerant and oil.
How often do you need to refill your refrigerator with freon?
Under normal operating conditions, the freon in the refrigerator Atlant is not consumed and does not require refilling. Refilling is only necessary in the event of a leak, which can occur due to mechanical damage, corrosion or manufacturing defects. The average service life of the system without leaks is 10–15. years.
What will happen if you fill a refrigerator with R600a with R134a?
If you fill it with R134a instead of R600a, the compressor will operate under the wrong load, which will lead to its overheating and rapid wear. In addition, R134a is incompatible with. oil for R600a, which will accelerate the failure of bearings and seals. In the best case, the refrigerator will not freeze well, in the worst case, the compressor will burn out.
Is it possible to determine the type of freon by the model of the Atlant refrigerator?
Yes, by the model of the refrigerator you can find out the type of refrigerant.
- Find the full model name (for example, Atlant MHM 1705-00) on the nameplate or in the passport.
- Check the information in the instructions or on the official website Atlant.
- Contact the service center indicating the model - they will tell you the exact type of freon.
Typically, models manufactured before 2010–2015 run on R134a, while newer ones run on R600a.
Why is R600a leaking in an apartment dangerous?
R600a (isobutane) is flammable, but for ignition a gas concentration in the air of at least 1.3% is required. In domestic conditions, this is unlikely, since this would require the leakage of almost all the freon from the system (about 100–150 grams) in a closed room. However, if there is a large accumulation of gas (for example, in a basement or small room), there is a risk of explosion if a spark is present. Therefore, if you suspect a leak of R600a, you need to ventilate the room and not use electrical appliances until the problem is resolved.
