Fast freeze
It is the forced freezing mode, in which the temperature inside the freezer is briefly reduced to -24 °C. This mode is intended for the case when you need to freeze numerous products at the same time — without a sharp decrease in temperature, the heat from numerous non-frozen products could lead to its critical increase.
Usually, the fast freeze mode must be turned on in advance — 5 to 6 hours before loading the products. Thus the freezer has time to decrease the temperature in the chamber. In this case, it is necessary to take into account the increased load on the compressor — it is impossible to turn on fast freeze for a long time. In some models, automatic shutdown of the fast freeze mode is provided. In some, it must be done manually.
Climate class
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.
Door panel hinge
—
Sliding hinget. A sliding hinge involves the connection of a decorative panel with a freezer door using movable guides. So, with the sliding hinge, the front decorative facade is equipped with its hinges, and the freezer door is practically not loaded by the panel. On the other hand, with this type of hinge, there is a small gap between the decorative panel and the freezer door, in which dust can accumulate. Additionally, the sliding hinge does not allow the freezer door to be opened more than 90-95˚.
—
Fixed hinge. With a fixed hinge, the panel is hung on the freezer door. It is the easiest and fastest option for installing the decorative panel. The fixed hinge assumes that the decorative panel loads the door hinges of the freezer. When choosing the fixed hinge for the panel, it should be taken into account that if the door of the freezer is not sufficiently reliable, the door of the built-in unit may be overloaded. Most often, the fixed hinge of the panel is used when installing a relatively small freezer. The compact panel is unlikely to overload the freezer door.
