When choosing a new refrigerator, you have probably come across the term "dry freezing" or No Frost. Marketers are actively promoting this technology as a revolutionary solution that eliminates the need to defrost the freezer. But what is actually hidden behind this concept? Why are some users delighted with dry freezing, while others prefer classic models with a drip system?
In this article we will look in detail at how the technology works No Frostdiffers from traditional cooling systems, and what nuances are important to consider when purchasing. You will learn why food can dry out faster in a dry freezer, how to properly store food in such refrigerators, and which models (Samsung RB37, LG GC-B247, ATLANT XM 6025-031) are considered the most reliable in 2026–2026.
Spoiler: dry freezing - this is not just a marketing ploy. This is a complex engineering system that has both undeniable advantages and hidden pitfalls. Next - an honest analysis without embellishment.
What is dry freezing in the refrigerator?
Dry freezing (English No Frost, literally - “without frost”) - This is a cooling technology in which moisture does not accumulate on the walls of the freezer in the form of ice. Unlike classic refrigerators, where frost forms naturally and requires regular defrosting, here the ice crust simply does not appear.
How does it work? There is faninstalled inside the chamber, which evenly distributes cold air across all shelves. The moist air released by the products does not settle on the walls, but is discharged through special channels into a separate compartment - evaporator. There, the moisture condenses and evaporates automatically without forming ice.
It is important to understand: No Frost there are two types:
- 🔹 Full No Frost —dry freezing also works in the refrigerator, and in the freezer compartment.
- 🔹 Frost Free is a combined system where the freezer is equipped with No Frostand the refrigerator compartment uses drip defrosting.
Many people mistakenly think that No Frost completely eliminates the formation of condensation. In fact, a small amount of frost may appear, for example, if you keep the door open for a long time or if you place hot food in the freezer. However, under normal conditions, the ice “coat” does not grow.
How the No Frost system works: technical details
To understand why refrigerators with dry freezing are more expensive than classic ones, let’s look at their structure. Main components of the system:
- 🌀 Fan — air circulates through the chamber, preventing local icing zones.
- 🧊 Evaporator — hidden behind the rear panel; here the moisture crystallizes and melts automatically.
- 🔥 Heating element (heating element) - periodically turns on to melt the ice on the evaporator.
- 📊 Temperature and humidity sensors - regulate the operation of the system for optimal microclimate.
The operating cycle No Frost looks like this:
- The fan takes moist air from the chamber and directs it to the evaporator.
- On a cold surface evaporator, the moisture condenses into frost.
- After 8–12 hours (depending on the model), the heating element turns on, which melts the ice.
- Water flows into the pan and evaporates naturally.
Interesting fact: in refrigerators Samsung and LG the latest generations are used double evaporator -separately for the refrigerator and freezer compartments. This allows more precise control of humidity and temperature, and also reduces the load on the compressor.
| Component | Purpose | Frequent faults |
|---|---|---|
| Fan | Air circulation | Freezing of blades, noise during operation |
| Evaporator | Moisture condensation | Icing, corrosion |
| Heating element | Evaporator defrosting | Burning, incorrect operation |
| Temperature sensor | Climate control | Inaccurate readings, malfunctions |
Why can ice still appear in No Frost?
If an ice crust forms in the freezer, the reasons are usually the following:
1) Prolonged opening of the door —warm air penetrates inside, moisture condenses.
2) Faulty seal —the seal of the chamber is broken.
3) Overload with products —air circulation is blocked.
4) Failure of the heating element or sensors —diagnostics required.
Pros and cons of dry freezing: an honest analysis
Technology No Frost actively advertised by manufacturers, but let's be objective Let's evaluate its strengths and weaknesses.
Advantages:
- ✅ No need for defrosting —the system itself copes with frost.
- ✅ Uniform cooling —the temperature is the same on all shelves.
- ✅ Rapid temperature recovery after opening the door.
- ✅ Less bacteria - low humidity inhibits the proliferation of microorganisms.
Disadvantages:
- ❌ Foods dry faster —due to air circulation, food may lose moisture.
- ❌ Higher consumption electricity —fan and heating element increase consumption by 10–15%.
- ❌ Noisy operation —the fan creates a background hum (25–45 dB).
- ❌ Expensive repairs —replacing the evaporator or fan is more expensive than in drip models.
Critical feature: food without packaging cannot be stored in refrigerators. Meat, fish, fruits and vegetables quickly weather and lose their taste. No Frost You cannot store food without packaging. Meat, fish, fruits and vegetables quickly become weathered and lose their taste. Use containers with lids or cling film.
Dry freezing vs drip system: which is better?
The choice between No Frost and drip defrosting depends on your priorities. Let's compare the key parameters:
| Parameter | No Frost | Drip system |
|---|---|---|
| Care | Does not require defrosting | Defrosting 1-2 times a year |
| Humidity in the chamber | Low (food dries) | High (food stays juicy longer) |
| Energy consumption | Higher by 10–15% | Lower |
| Cost | 20–30% more expensive | Budget models |
| Noise | 40–45 dB (fan) | 35–40 dB (quieter) |
The drip system (also called “crying”) is suitable for those who:
- 🍎 Stores a lot of fresh fruits/vegetables without packaging.
- 💰 Looking for a budget option.
- 🔇 Sensitive to noise.
No Frost optimal for:
- ❄️ Lovers of frozen semi-finished products and meat.
- 🏠 Large families (frequent door opening).
- 🕒 Busy people who do not want to waste time for defrosting.
How to properly operate a dry freeze refrigerator?
Even the most advanced technology requires proper handling. Here are the key rules:
Do not overload the shelves (air circulation must be free)
Store food only in packaging or containers
Do not place hot foods (wait until they cool to room temperature)
Regularly wipe the door seal (once a month)
Once every six months, clean the back wall from dust (for better ventilation)-->
Errors that shorten the service life No Frost:
- 🚫 Ignoring error signals - if the refrigerator beeps or the indicator blinks, check the door tightness.
- 🚫 Use of sharp objects to remove ice (the evaporator may be damaged).
- 🚫 Long-term disconnection from the network —if the refrigerator has been idle for more than a week, let it stand for 2-3 hours before turning it on.
Important: in models with Full No Frost (for example, Bosch KGE39XL40 or Indesit ITF 118 W) You cannot turn off the ventilation even for a short time. This can lead to icing of the evaporator and breakdown.
Top 5 myths about dry freezing
Around technology No Frost there are many misconceptions. Let's look at the most common ones:
Myth 1: “No Frost does not require maintenance at all”
🔹 Reality: Although defrosting is not necessary, the refrigerator still requires cleaning. Dust on the back wall impairs heat transfer, and the seal needs to be wiped to prevent it. lost elasticity.
Myth 2: “In No Frost, food lasts longer”
🔹 Reality: The shelf life depends on the temperature, and not on the type of defrosting. In the freezer No Frost foods do not spoil faster, but they can dry due to air circulation.
Myth 3: “No Frost is more economical than drip refrigerators”
🔹 Reality: On the contrary, energy consumption is higher due to the operation of the fan and heating element. The difference in electricity bills can reach 10–15% per year.
Myth 4: “You cannot store fresh vegetables and fruits in No Frost”
🔹 Reality: You can, but only in special containers with controlled humidity (for example, Fresh Zone v models Samsung).
Myth 5: “No Frost breaks down more often than drip systems”
🔹 Reality: Repair statistics show that breakdowns No Frost are mostly associated with incorrect operation (overloading, ignoring error signals with proper care). the system serves no less than a drip system.
Why is No Frost more popular in the USA and Europe than in Russia?
In Western countries they prefer No Frost because of:
1) Cultures of consumption - more semi-finished products and frozen foods.
2) High water tariffs — defrosting classic refrigerators requires a lot of water for washing.
3) Energy efficiency standards —modern models No Frost class A+++ they do not consume much more than drip ones.

FAQ: Frequently asked questions about dry freezing
Is it possible to turn off the No Frost refrigerator for a long time?
Yes, but before turning it on again, let it stand for 2-3 hours at room temperature. This is necessary so that the oil in the compressor is evenly distributed. If you immediately turn on the refrigerator after inactivity, the risk of compressor failure increases.
Why does ice form in my No Frost freezer even though the system is supposed to prevent this?
The reasons may be different:
- 🔌 The door is not tightly closed — check the seal.
- 🍲 Hot foods — let them cool before freezing.
- ❄️ Failure of the heating element —diagnostics required.
- 📦 Overload cameras —air does not circulate.
If ice appears regularly, call a technician to check the evaporator and sensors.
How often should you wash a dry freeze refrigerator?
It is recommended to carry out general cleaning once every 3-4 month:
- Unplug the refrigerator.
- Take out all the food and shelves.
- Wipe the walls and seal with a soda solution (1 tbsp per 1 liter of water).
- Rinse the ventilation holes (do not use sharp items!).
- Dry the chamber and turn on the refrigerator.
Is dry freezing harmful to health?
No, technology No Frost absolutely safe. The myth of “harmfulness” is associated with the fact that the fan supposedly “spreads bacteria.” In fact, air circulation, on the contrary, prevents the formation of mold and unpleasant odors. The main thing is to follow the rules for storing food and regularly clean the refrigerator.
Is it possible to install a No Frost refrigerator in an unheated room (for example, in a country house in winter)?
No, for most people. models No Frost requires an ambient temperature in the range +16...+32°C. At subzero temperatures:
- The oil in the compressor thickens.
- The electronics may malfunction.
- The seal loses elasticity.
If you need a refrigerator for your dacha, choose models with climate class SN-T (for example, ATLANT MXM 1705-80), which operate under +10...+43°C.
