Modern refrigerators have ceased to be just freezers with shelves, turning into complex climate systems to preserve the quality of products. One of the key technologies that manufacturers like LG, Samsung and Bosch are introducing is a special retractable container, often labeled as Flexi Use Box. This zone is designed to create ideal storage conditions for products that require a special temperature regime, different from the main chamber.
Many users are faced with the question of where exactly to put meat, fish or delicacies so that they remain fresh for as long as possible without freezing into stone. The answer lies in the correct use of this specialized container. Flexi Use Box (or zero temperature zone) allows you to regulate the microclimate, extending the shelf life of perishable goods several times compared to a regular shelf.
In this article we will analyze in detail the functionality of this system, learn how to adjust temperature conditions and find out what mistakes refrigerator owners most often make when using this compartment Understanding the principles of operation freshness zones will help you save money on groceries and always have quality food at hand.
The principle of operation and purpose of the Flexi Use zone
The main task of the system Flexi Use Box is to maintaining a temperature close to 0°C, which is the optimal condition for slowing down the proliferation of bacteria without freezing the cellular structure of the products. Unlike the main chamber, where the temperature is usually +3...+5°C, conditions are created in this compartment under which the biochemical processes in the products practically stop. This is achieved through the insulated design of the box and a special cold air supply system.
The design of the box often provides for the possibility of changing its volume or temperature profile. In some models, the bottom of the box can be raised or lowered, changing the internal space, which allows you to place both small packages and large pieces of meat or whole fish there. Cooling technology can be implemented through a separate air duct or through a special panel in contact with the contents.
⚠️ Caution: Do not load the Flexi Use Box with hot or warm foods. A sudden temperature change will disrupt the operation of the sensors and can lead to a temporary increase in temperature in the entire chamber, which is dangerous for the supplies already lying there.
It is important to understand that zero zone is not a freezer. The temperature here does not drop below -1...-3°C depending on the settings, so the products are not covered with an icy crust, maintaining their texture and juiciness after defrosting (which, in fact, is not required). This is critical for steaks, fish fillets and fresh herbs.
Temperature settings and settings
Control of drawer parameters Flexi Use Box can be carried out mechanically or electronically, depending on the model of your refrigerator. With electronic systems, you can precisely set the desired temperature via the control panel on the door. Mechanical controls are often dampers or switches inside the box itself that change the intensity of the flow of cold air.
There are several basic operating modes that you need to know for effective use:
- ❄️ Meat/Fish mode: sets the temperature around -1...0°C, ideal for storing raw meat, poultry and seafood for several days.
- 🥬 Vegetables/Fruits mode: raises the temperature to +1...+3°C and often regulates humidity, preventing greens from wilting and fruit spoilage.
- 🍷 Cooling mode: universal mode for drinks or foods that need to be quickly cooled before serving.
When setting, it is important to take into account the fullness of the box. If Flexi Use Box is packed tightly with food, air circulation may be difficult and the sensors will show incorrect values. It is recommended to leave a small space between packages for free circulation of air flow.
Some advanced models allow you to switch the entire box to quick freezing mode, temporarily lowering the temperature to freezer compartment values. This is useful if you have bought a lot of products and want to quickly prepare them for long-term storage, but constantly maintaining this mode is not recommended due to increased energy consumption.
What can and cannot be stored in the Flexi Use Box
Proper zoning of products inside the refrigerator is the key to their long-term preservation. The zone Flexi Use is created for specific categories of goods, and placing unsuitable products may lead to their spoilage or loss of taste. Below is a table to help you navigate the distribution of supplies.
| Product type | Recommended mode | Shelf life (approximate) | Features |
|---|---|---|---|
| Fresh meat (beef, pork) | Meat / -1°C | up to 7 days | Does not freeze, retains juiciness |
| Fish and seafood | Fish / -1°C | 2-3 days | Requires sealed packaging to prevent odors |
| Greens and salads | Vegetables / +2°C | up to 10 days | Do not wither, retain turgor |
| Dairy products (opened) | Universal / 0°C | by shelf life | Souring is slowed down |
It is strictly not recommended to store tropical fruits (bananas, mangoes) in the zone zero temperature as they can turn black and lose their taste at temperatures close to zero. Also, you should not put baked goods there - they will quickly go stale due to low humidity and temperature.
Packaging requires special attention. If you store foods with strong odors (such as smoked fish or blue cheese), use airtight containers or vacuum sealed bags. The system Flexi Use often has a general circulation of air inside the refrigerator, and odors can migrate to other compartments if insulation is not taken care of.
☑️ Checking the readiness of products for storage
Design features and volume control
One of the unique features Flexi Use Box is the possibility of transforming the internal space. In many models of LG refrigerators and similar systems, the bottom of the drawer is a movable platform. By lowering the bottom, you increase the height of the available space, which allows for tall bottles, pots or large pieces of meat.
By raising the bottom to the upper position, you reduce the volume of the drawer. This is not just a space saver, but a way to speed up the cooling of small quantities of food. In a small volume, cold air circulates faster and the temperature stabilizes in a shorter time. This is especially true when you need to quickly cool drinks or a small portion of food for dinner.
⚠️ Attention: When moving the bottom of the drawer, make sure that it locks into the grooves until it clicks. A loosely installed bottom may become warped, which will lead to jamming of the box or disruption of the tightness of the freshness zone.
The walls of the box are usually made of durable plastic, resistant to low temperatures and mechanical stress. However, you should avoid impacts with heavy objects (for example, frozen briquettes), since plastic becomes more brittle at low temperatures. Design of guides Also requires caution: do not pull out the drawer sharply if it is completely full, so as not to damage the sliding mechanism.
Can the Flexi Use drawer be washed? in the dishwasher?
In most cases, the plastic elements of the Flexi Use Box are made of heat-resistant plastic, which can be washed in the dishwasher under gentle conditions (up to 45-50°C). However, rubber seals or electronic components (if they are built into the box itself and not into the wall of the refrigerator) can be damaged by high temperatures and aggressive detergents. It is recommended to wash the box by hand with warm water and a mild detergent to ensure a long service life of all elements.
Care, cleaning and maintenance of the system
To maintain hygienic safety and efficient operation fresh zones it is necessary to clean it regularly. It is recommended to wash the box Flexi Use Box at least once a month, and in case of spills or contamination - immediately. The use of aggressive chemicals, chlorine-containing products or abrasive sponges is prohibited, as they can damage the plastic surface and make it dull or rough.
The cleaning process includes the following steps:
- 🧼 Removal: completely remove the drawer from the refrigerator. If the bottom is removable or adjustable, it is also better to remove it for a good wash.
- 🚿 Washing: rinse all parts with warm water using a mild dishwashing detergent. Rinse thoroughly to remove chemical residue.
- 🌬️ Drying: wipe the elements dry with a soft cloth and allow them to dry completely at room temperature before putting them back.
Pay special attention ventilation holes inside the niche where the box is installed. Dust and small crumbs can accumulate there, which interfere with normal air circulation. Wipe these areas with a damp cloth when defrosting the refrigerator or general cleaning.
Typical problems and methods for solving them
During operation, users may encounter a number of typical situations that are not breakdowns, but require intervention. For example, food in a drawer may begin to freeze. This often indicates that the temperature setting is too low or the drawer is overloaded, blocking air access to the sensor. The solution is simple: switch the mode to “Vegetables” or reduce the amount of food.
Another common problem is condensation or ice on the walls of the box. This may occur due to frequently opening the refrigerator door, not closing the door tightly, or storing food in open containers that actively evaporate moisture. Check the refrigerator door seals and try not to keep the door open longer than necessary.
If you notice that the temperature in Flexi Use Box is not the set temperature, check to see if the vents are blocked by food. It is also worth checking the settings of the main refrigerator compartment: if it is too cold in the main chamber, then the temperature in the freshness zone may drop below normal.
Why do products freeze in the Flexi Use Box zone?
Freezing of products in the freshness zone usually occurs for three reasons: the “Meat” or “Quick Cooling” mode is set when there is a small amount of food, the box is located too close to the cold air outlet, or the thermostat is faulty. Try raising the temperature by 1-2 degrees or moving the food away from the back wall of the box.
Can you store baby food in the Flexi Use Box?
Yes, you can, but with caution. It is better to store ready-made baby food at a temperature of +2...+4°C, so use the universal mode or the mode for vegetables. Do not freeze ready-made mixtures in this compartment if they are not intended for freezing, as the structure may be damaged.
How to change the volume of the Flexi Use box?
To change the volume, grab the special handles or protrusions on the bottom of the box (inside). Smoothly raise or lower the platform until the latches click. Make sure that the platform is level and not skewed.
What to do if the box does not move out well?
Check whether foreign objects have gotten under the guides. Make sure the refrigerator is level and not tilted backwards. If the drawer is overloaded, try removing some food. It is strictly prohibited to lubricate the guides with oil or grease - use only food-grade silicone grease if absolutely necessary.
Does filling the box affect energy consumption?
Yes, it does. A fully filled box (especially with products with a high water content) acts as a cold accumulator, helping to stabilize the temperature and reducing the frequency of compressor starts. An empty box requires more energy to maintain a low temperature when the door is opened.
