Comparison Atlant M 7401-100 85 L vs Hansa FS100.3 98 L

— Freezer. A device for storing frozen food, made in the form of a cabinet with a vertically located door. Freezers are convenient because they can occupy a relatively small area with significant capacity.

— Chest freezer. A device for storing frozen food, made in the form of a chest, that is, a horizontally located box, in which the top cover acts as a door. The chest has a small height and, as a result, occupies a larger area than freezers. On the other hand, they are more convenient for storing bulky products and allow you to use the entire working volume without dividing it into boxes.

— Display chest showcase. Freezer designed for commercial use. It has a transparent top cover through which the buyer can view the product without opening the device; the same cover usually serves as a door. Display chest showcases can be seen in modern stores. They store ice cream and semi-finished products.

— Ice maker. Unlike other types of freezers, the ice maker is designed not to store food but to produce edible ice in large quantities. Such units are widely used in cafes, restaurants and bars, where chilled drinks often have to be prepared.

— Shock freezer. A shock freezer is a high-capacity freezer. Shock freezing involves the processing of products with a temperature of 30 to 50 °C below zero. At this tempe...rature, the tissue structure freezes at the micro level. It is very important because, in the products subjected to shock freezing, the tissues are not damaged so that the products will not turn into a liquid during defrosting, and it also makes it possible to preserve the original microelement and vitamin composition in the products. Thanks to shock freezing, you can harvest any vegetables, berries, fruits, etc. After defrosting, the products will acquire the same appearance and taste properties as at the start of shock freezing. After quick and deep freezing, the low-temperature zone switches to the mode of operation of an ordinary freezer.

It is the total working capacity of the freezer. A larger capacity allows you to accommodate more products but affects the dimensions and cost of the unit. Therefore, when choosing according to this parameter, you should not chase after the maximum capacity but the capacity you really need. For example, the average required capacity is 50 litres per person. And when choosing a display chest freezer (see "Product type"), you need to take into account the number of products offered for sale.

It is also worth considering that the freezer is often divided into several compartments (see below) - which means that a large capacity does not guarantee that large pieces of food can fit in the device.

it is the number of compartments provided in the design of the freezer. In some models, it is possible to set different temperatures for different compartments. It is worth noting that a large number of boxes does not always mean maximum convenience, since, with an increase in their number, the volume of each individual box inevitably decreases.

The lowest temperature that the freezer can maintain in normal operation. First of all, the duration of food storage in the freezer depends on this parameter: it is believed that a temperature of -12 ° C is enough to preserve food for a month, -18 ° C – 3 months, -24 ° C – up to a year. At the same time, it must be taken into account that not only temperature affects the shelf life but also the type of product and its quality before freezing.

The amount of time the freezer keeps food cold enough when the refrigeration system is turned off, for example, due to a breakdown or power outage. Technically, the power failure autonomy for each model is calculated differently; For example, for a freezer with an operating temperature of -18 ° C, this is the period during which the products in the chamber heat up from -18 ° C to -9 ° C. To sum up, the time is indicated during which the frozen products are guaranteed not to heat up to a temperature at which they could lose their properties.

One of the main indicators of freezer performance is the approximate amount of fresh food that the freezer can completely freeze from room temperature to the minimum operating temperature in 24 hours. For domestic use, a power of 10-15 kg/day is considered quite sufficient. More performant models may be required if you have to freeze a lot of food at a time or for industrial purposes.

The type of control provided in the freezer. This parameter is specified by the type of controls and their location.

- Rotary knobs. In general, this is the simplest and most inexpensive option used in units of the appropriate level. However, even this is quite enough - especially if the freezer works in more or less constant temperature conditions (for example, in a home or office kitchen). In many cases, the matter is limited to selecting the appropriate knob position once and then not changing the settings. In addition, the major advantages of this type of control are reliability and ease of repair.

- Push-buttons. Push-buttons are considered more advanced than rotary knobs. The specific functionality of freezers with such a control may be different. But among them, models with additional functions and the ability to fine-tune the temperature are noticeably more common. As for the location, there are internal and external push-buttons. The internal location allows you to hide the control panel behind the refrigerator door, providing a neat appearance with a minimum of protruding parts.
The external location is convenient because you do not need to open the door to access the settings. On the other hand, the real need for such an arrangement is not so often, and the control panel must also fit into the overall design of the unit (which is not always possible to do in the best way).

- Touch controls. Touch controls are considered th...e next step in the development of control panels, after buttons. So, it looks stylish and technologically advanced, they do not need to be pressed hard (just touched), and there are no protruding parts, corners or slots on the surface of the panel, which simplifies cleaning from dirt. The presence of a touch panel is typical mainly for models of the middle and top levels. It costs a little more than a push-button one, but this is imperceptible against the total price of the units. But the internal location, in this case, is much less common than the external one. It is because there is no need to hide the touch panel behind the door. It can easily fit into the design of the device. In addition, external placement allows you not to open the door again to access the settings.

It is the average amount of energy consumed by the freezer in a year of operation. Of course, these figures are not absolutely accurate. The actual power consumption may vary depending on the specific operating conditions. However, this parameter makes it possible to evaluate the consumption of the device and compare different models with each other. At the same time, it often turns out to be more convenient and visual than the energy consumption class (see above) because, in this paragraph, we are talking about a specific figure (from which you can also calculate the cost of electricity consumed).

The climate class to which the freezer corresponds.

As the name implies, this parameter describes the environmental conditions for which the unit is designed. The warmer it is around, the more powerful the freezer should be and the better thermal insulation it should have. Specific classes are indicated by letters. Here are the most popular options:

— SN (subnormal). Models for a cool temperate climate have an operating range from +10 °C to + 32 °C. Such a unit can be useful in a poorly heated room where the temperature can drop below +16 °C — for example, on the veranda of a private house, in a garage, etc.

— N (normal). Freezer for a temperate climate, with an operating temperature range of +16...+32 °C. Such a unit is suitable for most residential apartments and houses in mid-latitudes.

— ST (subtropical). Models for subtropical and humid tropical climates. Normally they work at the range of external temperatures +18...+38 °C.

— T (tropical). Refrigerators for dry tropical climates. Designed for temperature range +18 °C to +43 °C.

Also, note that there are many models on the market with an extended temperature range covering several classes. For example, a unit labelled N-ST will have a temperature range of +16...+38 °C. These freezers are indispensable in climates, conditions which are not covered by one standard class — for example, in cold winters and hot summers.
