Comparison Liebherr UIG 1323 vs Liebherr UIG 1313

The total working volume of the freezer compartment. A larger volume allows for more products to be stored, but it affects the size and cost of the unit; therefore, when choosing based on this parameter, it's important not to chase maximum capacity but to consider what volume you actually need. For example, for household use, the average necessary volume is 50 liters per person; and when choosing a display freezer (see "Type"), you need to consider the number of products to be sold. More detailed recommendations for selecting the optimal volume can be found in specialized sources.

It is also worth considering that the freezer is often divided into several compartments (see below) — which means that a large volume does not necessarily guarantee that large pieces of products can fit into the device.

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 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.

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.

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 average noise level generated by the freezer during operation. The quietest models give out about 25 - 30 dB — this is the average noise background in a residential area at night (comparable to the ticking of a wall clock); the loudest — is about 60 dB (loud conversation). More detailed comparison tables can be found in special sources.

In any case, the lower the noise level, the more comfortable the use of the unit. However, it does not always make sense to look for the quietest freezer: in some situations (for example, in a noisy workshop), the freezer's sound may be lost against the surrounding noise background. In addition, reduced noise often affects the price.
