Methodology presents the most energy efficient professional storage refrigerators and freezers on the European market. All listed products use natural climate-friendly refrigerants.


The products listed:

Technical criteria

All models on meet the following criteria:

Category Energy efficiency index Min. energy efficiency class
Storage counter refrigerators <25 A
Storage refrigerators 1-door <25 A
Storage refrigerators 2-doors <50 C
Storage counter freezers <35 B
Storage freezers 1-door <50 C
Storage freezers 2-doors <75 D
Storage refrigerator-freezers <75 D
Addition to the technical criteria: Storage refrigerator-freezers and static storage cabinets are excempt from the EU energy label. In the Topten product lists they can nevertheless be listed, under the condition that their energy consumption is determined according to the here mentioned harmonised testing standards. With the standard values, the energy efficiency index EEI can be calculated according to the EU energy label in the same way as for the other cabinets. Storage refrigerator-freezers are to be classified as vertical freezers for the calculation.

Topten accepted test standards

The test standards for the declaration of the energy consumption of storage refrigerators and freezers are regulated in EU regulation 2015/1094. Topten accepted standards for storage refrigerator-freezers and static storage cabinets can be found here.

Order of presentation

Products are ranked according to energy efficiency index. The order of presentation can be changed by clicking on the rows' headings. Compare models by checking them and clicking on compare.

EU energy label

Since 1 July 2016, the EU energy label for professional refrigerated storage cabinets are mandatory. It shows:

  • the energy efficiency class,
  • the annual electricity consumption in kWh per year,
  • the sum of the net volumes of all chilled compartments functioning at chilled operating temperature,
  • the sum of the net volumes of all chilled compartments functioning at frozen operating temperature,
  • and the climate class (3, 4 or 5) together with the associated dry bulb temperature (in °C) and the relative humidity (in %).

Document: Commission delegated regulation (EU) 2015/1094

Countries available

This item displays the availability of models in European countries according to producers’ information. "EU" means that the model is available in all or most European countries. If the model is available in a number of countries only they are indicated by country codes according to ISO. "On demand" means that producers could not indicate the availability and that consumers have to ask in their countries on their own.
