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.

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 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.

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.
