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.

Telescopic rails

Retractable guides allow the drawer to roll smoothly on a special roller. The main advantage of telescopic rails is that you do not need to make much effort. On the other hand, such devices are more expensive and are used in premium segment devices.

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.

Ice maker

It is a separate device for producing edible ice in the freezer. One of the advantages of such freezers is that the ice is produced and stored separately from other products and thus does not absorb foreign odours.

Lighting

Freezer interior lighting system. This function is very helpful given that the working chamber of the unit, even with the door open, is often shaded, and it is not so easy to see its contents. The lighting usually works automatically — similar to how it is implemented in refrigerators: the light turns on when the door is opened and turns off when it is closed.

Door closer

The door auto-closer is responsible for “pulling” the door when closing, and in some models also when opening. The idea is that the user does not need to close/open the door completely: pull it to the right place, and then the door will be "picked up" by the auto-closer and smoothly brought to a fully open or closed state. Such a system performs two functions. Firstly, it reduces the risk of leaving the freezer not closed. Secondly, such a device provides a very smooth opening and closing without shock. Thus it has a positive impact on the life span of the entire device.

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.

Child lock

The child lock allows you to block freezer controls and/or access to its internal volumes. This function will be useful in families where there are small children. Thus, the child will not be able to get to the freezer controls and change its operation mode.

Energy consumption per year

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).
