Superfreeze in the refrigerator: purpose, principles of operation and secrets of effective use

Have you ever noticed that after purchasing fresh fish or meat on the packaging it is written: “To preserve quality, use the superfreeze mode”? Or maybe your new refrigerator Samsung or LG flashed a previously unknown button Super Freezeand the instructions remained unopened? If yes, then you are not alone. superfreeze mode is one of the most underrated functions of modern refrigerators, although it can significantly extend food freshness and save your time.

In this article we will not just explain what is superfreeze, but will also reveal the nuances of its operation, which manufacturers often keep silent. You will learn why this mode is important for frozen berries, but can ruin the ice cream, how to turn it on correctly in models Bosch, Indesit or Atlant, and what to do if the function suddenly stops working. Let’s also look at myths, for example, that superfreeze “eats” electricity or damages the compressor. Are you ready? Then let's start with the main thing.

What is superfreeze and why is it needed in the refrigerator? data-i="61">) is a special mode

Superfreeze (English) Super Freeze, there are also names Quick Freeze, Power Freeze or Turbo Freeze) is a special mode ultra-fast freezingthat is activated in the freezer compartment. Its main task is to quickly reduce the temperature of fresh food to −18°C and below, so that the ice crystals inside the cells form small and evenly. This prevents the destruction of tissue structure and preserves taste, color and beneficial properties.

Why is this important? Imagine putting fresh strawberries or chicken in the freezer. During normal freezing (for example, at −12°C), the water in food turns into large ice crystals, which literally “tear” the cells from the inside. As a result, after defrosting, strawberries become mushy, and the meat loses juice. Superfreeze solves this problem, freezing products 2-3 times faster - due to a temporary decrease in temperature to −24...−30°C.

• ❄️ Texture preservation: the berries remain intact, the meat does not lose juiciness.
• 🕒 Time saving: freezing takes 1-2 hours instead of 6-8.
• 🦠 Safety: quick freezing inhibits the growth of bacteria.
• 💰 Savings: you can buy products in bulk at sales.

However, there is a nuance: superfreeze mode not intended for constant use. It turns on only for a limited time (usually 24-72 hours), after which the refrigerator automatically returns to the standard temperature. This is done to protect the compressor from overloads and save energy.

How superfreeze works: technical details

To understand why superfreeze is so effective, let’s understand its structure. In most modern refrigerators (for example Liebherr, Electrolux or Beko) this mode works according to one of two principles:

1. Increased operation of the compressor: the engine starts working at maximum power, increasing the circulation of the refrigerant and lowering the temperature in the freezer to −24...−30°C.
2. Additional fan (in models with the system No Frost): accelerates the distribution of cold air, excluding “warm zones” in the chamber.

In refrigerators with static system (drip defrosting) superfreeze is implemented more simply - the compressor simply works longer without stopping. And in advanced models (for example, Samsung Twin Cooling Plus), the freezer and refrigerator compartments have separate cooling circuits, which allows you to freeze food in superfreeze without affecting the temperature in the main compartment.

Important: in some refrigerators (for example, Atlant or Stinol) superfreeze activates automatically when the freezer door is opened or a large amount of warm food is placed. In other models, it must be turned on manually - we will talk about this in the next section.

⚠️ Attention: If your refrigerator was manufactured before 2010, it may not have a superfreeze mode or work according to an outdated scheme (for example, without automatic shutdown). In this case, prolonged use of the function may lead to compressor overload.

How to turn on superfreeze: step-by-step instructions

The process of activating the mode depends on the model of the refrigerator. We have collected instructions for the most popular brands. If your brand is not on the list, look for a button with the ❄️❄️ icon or inscription Super Freeze/Quick Freeze on the control panel.

Place the products in a single layer on the shelves (not in drawers)

Make sure the freezer door is tightly closed

Do not load the chamber by more than 70%

Check that the temperature in the freezer is not higher than −15°C-->

Refrigerators Samsung (RB, RT, RS series)

1. Press the button Freezer (or Fridge, if the freezer is at the bottom) on the display.

2. Hold it for 3 seconds until the indicator Power Freeze.

3 lights up. The mode will turn off automatically after 50 hours (or earlier if the temperature reaches −25°C).

Refrigerators LG (GA, GB, GC series)

1. Find the button Express Freeze on the panel (usually on the right).

2. Press it once - the indicator will light up, and a timer will appear on the display (usually 72 hours).

3. To cancel, press the button again.

Refrigerators Bosch/Siemens (KGN, KIN series)

1. Press the button Super (with the snowflake icon) and hold for 2 seconds.

2. The message SuperFrost and a countdown timer will appear on the display.

3. The mode will turn off after 65 hours or when reaching −28°C.

Refrigerators Atlant/Stinol (mechanical control)

1. Turn the freezer temperature control to the maximum value (usually “7” or “Super”).

2. After 24 hours, return the regulator to the standard position (“3” or “4”).

If, after turning on the superfreeze, the refrigerator begins to make loud noise, this is normal: the compressor is operating at maximum power. However, if the noise is accompanied by vibration or knocking, immediately turn off the mode check the refrigerator for malfunctions (read about this in the “Problems” section).

What products can (and cannot!) be frozen in superfreeze

Not all products tolerate ultra-fast freezing equally well. Here's what should be frozen in superfreeze:

• 🍓 Berries (strawberries, raspberries, currants) - they will retain their shape and will not turn into porridge.
• 🥩 Meat and poultry (fresh or in vacuum packaging) - will not lose juiciness.
• 🐟 Fish and seafood - avoid the “fishy” smell after defrosting.
• 🍞 Yeast dough (dumplings, dumplings, pizza) - will not crumble.
• 🥬 Greens (parsley, dill, spinach) - if pre-blanched.

And these products not recommended are frozen in superfreeze (or even in the freezer):

• 🥔 Raw vegetables with a high content water (cucumbers, radishes, lettuce) - they will become soft.
• 🍅 Tomatoes —after defrosting they turn into “bags of water.”
• 🥛 Dairy products (sour cream, yogurt, cottage cheese)—separate.
• 🍳 Eggs in the shell —may burst.
• 🍦 Ice cream - in superfreeze it will become “stony” and lose its creamy texture.

Special case - ready meals (soups, borscht, sauces). They can be frozen in superfreeze, but only in portioned containers and without potatoes (they fall apart when defrosted).

⚠️ Attention: Never freeze in superfreeze carbonated drinks (even in plastic bottles) - they can explode due to the expansion of carbon dioxide. The same applies to hermetically sealed glass jars (for example, with homemade preparations).

Why can’t you freeze potatoes?

When frozen, the starch in potatoes turns into sugar, and when defrosted products become sweetish and watery. Additionally, potatoes darken due to oxidation. If you need to preserve potatoes, it is better to use drying or canning.

Common problems with superfreeze and their solutions

Even in new refrigerators, the superfreeze mode may not work properly. Here are the most common problems and ways to solve them:

If, after turning on the superfreeze, the refrigerator began freezing with ice (in models without No Frost), this may indicate:

• 🔧 Wear of the door seal —cold air comes out, the compressor works without stopping.
• 🌡️ Thermostat malfunction —the sensor incorrectly reads the temperature.
• ❄️ Clogged drainage hole —condensation does not drain, forming ice.

For diagnostics, try test mode:

1. Disconnect the refrigerator from the network for 1 hour.
2. Turn it on and activate it immediately superfreeze.
3. Check whether the temperature reaches −24°C in 2 hours (use a separate thermometer).

If the temperature does not drop below −18°C, the problem may lie in refrigerant leak or compressor wear. In this case, you cannot do without professional repairs.

Saving electricity: myths and reality

Many users are afraid to turn on superfreeze, believing that it “eats” kilowatts. Let's figure out if this is really so.

According to the laboratory Energy Star, the superfreeze mode increases the energy consumption of the refrigerator by 15-25% only during operation. However, thanks to quick freezing, the food stays cold longer, and the compressor turns on again later. As a result total electricity consumption per month increases by only 3–7%.

For comparison:

• 💡 Regular refrigerator (class A+) consumes ~35 kW/month.
• ❄️ With superfreeze (when used 2 times a week) - ~37 kW/month.
• 🔥 Electric kettle (when boiling 1 liter of water) spends 0.1–0.2 kW - the same as superfreeze for 1 hour of operation.

Tips on how to reduce consumption:

1. Do not turn on the superfreeze for the maximum time if you freeze few products.
2. Use the mode at night (electricity tariffs are lower).
3. Do not open the freezer door while the superfreeze is operating.

⚠️ Attention: In refrigerators with an inverter compressor (for example, Hitachi or Panasonic), the superfreeze consumes 40% less energy than in models with a conventional motor. This is due to the smooth power adjustment.

Alternatives to superfreeze: what to do if it is not in the refrigerator

If your refrigerator is not equipped with a superfreeze mode, do not despair. Here are several ways to achieve a similar effect:

• ❄️ Manual quick freezing:
  1. Set the freezer control to maximum (usually "7" or "Super").
  2. Place the food in a single layer on the top shelf (it's coldest there).
  3. Through 2-3 hours, return the control to the standard position.
• 🧊 Using ice:
  1. Before loading food, place ice packs or cold batteries in the freezer.
  2. This will temporarily lower the temperature by 3-5°C.

🔄 Preliminary cooling:

1. Place food in the refrigerator for 1-2 hours before freezing.
2. This will reduce the freezing time in the freezer.

For long-term storage of food without superfreeze, you can use vacuum sealers (for example, FoodSaver). They remove air, which slows down oxidation and bacterial growth. In combination with conventional freezing, this gives a result close to superfreeze.

If you often freeze large volumes of food, consider purchasing one separate freezer compartment with a function Shock Freeze. For example, models Liebherr GP 1476 or Beko FNE 110120 equipped with professional freezing systems that are superior to household refrigerators.

FAQ: Answers to frequently asked questions about superfreeze

Is it possible to leave the superfreeze on all the time?

No, this will lead to overload of the compressor and increased energy consumption. Most refrigerators automatically turn off after 24 to 72 hours. If your model does not do this, turn off the superfreeze manually after freezing the food.

Why do the products become covered with frost after the superfreeze?

This happens due to the entry of moist air when the door is opened. To avoid frost, wrap food in plastic wrap or vacuum bags before freezing. In refrigerators with No Frost frost forms less frequently due to forced air circulation.

Superfreeze and super cooling are the same thing?

No. Superfreeze is a mode in the freezer, and supercooling (Super Cool) - a similar function in the refrigerator compartment for quickly cooling drinks or perishable foods (for example, cakes). The temperature during supercooling drops to +2°C.

Is it possible to defrost food in superfreeze mode?

No, this contradicts the purpose of the function. Superfreeze is intended only for freezingand not for defrosting. For quick defrosting, use a microwave (mode Defrost) or cold water.

How often can you use superfreeze?

In modern refrigerators, the superfreeze mode can be turned on 2-3 times a week without harming the equipment. The main thing is not to exceed the operating time specified in the instructions (usually up to 72 hours). In older models (before 2015), it is better to limit yourself to 1-2 uses per month.
