Capacity

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.

No Frost

No Frost system inside the freezer. A special fan provides air circulation, while moisture condenses in the frost, not in the working chamber, but in a special compartment. Periodically, the fan turns off, the frost melts, and the meltwater flows into a special tray, from which it evaporates. Such a system eliminates the need to defrost the freezer to remove frost periodically. On the other hand, it imposes special requirements on the packaging of products, since in such freezers the products dehydrate fast.

Max. temperature

The highest temperature maintained by the freezer during normal operation. This parameter is not as important as the minimum freezing temperature, however, it allows to evaluate the optimal conditions for storing certain categories of products that do not need deep freezing. And in some cases, it shows that the freezer can work as a refrigerator.

Minimum temperature

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.

Power failure autonomy

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.

Freeze capacity

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.

Door alarm

It is a system that monitors the closing of the freezer door. If the door is not closed for a long time or is not closed tightly enough, an audible or light (depending on the model) signal is given. It helps to avoid a critical increase in temperature in the working chamber and preserves the quality of the products.

Display

The external display makes the operation of the freezer more intuitive and allows you to control the conditions inside without opening it. The display can show data on the temperature inside the chamber or individual drawers, running programmes and the state of their running(fast freeze, for example), etc.

Cold accumulators

The presence of removable refrigerants (cold accumulators) in the freezer design. This solution allows you to extend the temperature retention time in case of a power outage and also allows you to take it with you for use outside the freezer if necessary.
