Comparison Delfa DFH-140 163 L vs Elenberg MF-209 168 L

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 number of compartments provided in the freezer's design. They can be designed as pull-out drawers or shelves with a drop-down door. In some models, there is the possibility to set different temperatures for different compartments. It is worth noting that a large number of compartments does not always imply maximum convenience, as the volume of each individual drawer or shelf inevitably decreases with the increase in their number.

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.
