Refrigerated display cabinets are the main energy consumers in retail, which is why they are covered by strict EU energy efficiency regulations. Implementing the measures below lowers operating costs and CO₂ emissions.

1. Fitting cabinet doors – "closing" an open display case

The simplest retrofit is to install refrigeration doors on open display cabinets. Closing a cabinet this way can reduce energy consumption by up to 50%.

  • Commission Regulation (EU) 2019/2024 requires compliance with the energy efficiency index (EEI),
  • since 1 September 2023 tighter thresholds apply (for example EEI ≤ 80),
  • fitting doors supports the objectives of the EED directive (2023/1791/EU),
  • it is in line with circular economy principles – upgrading instead of replacing.

2. Ecodesign-compliant components

  • electric motors of class IE3 or higher (Reg. EU 2019/1781, EN 60034-30-1),
  • EC fans – higher efficiency, lower consumption (Reg. EU 327/2011 / 2024/1834),
  • condensers and condensing units with a high COP (EN 13215),
  • compressors certified to EN 12900.

3. High-efficiency LED lighting

LED modules improve product presentation and reduce electricity use. They should comply with Reg. 2019/2020 (efficiency in lm/W), EN 62471 (photobiological safety) and EN 60598 / EN 60335.

4. Maintaining a tight seal – gaskets, doors, hygiene

Gaskets and insulation are key to holding temperature and limiting losses.

  • gaskets tested for ageing (EN 14285), durability and tightness,
  • glass doors compliant with EN 12150 and EN 12600,
  • components in contact with food compliant with Reg. EU 1935/2004 and EN 1672-2,
  • self-closing hinges prevent doors being left open.

Regular maintenance – cleaning the condenser, checking gaskets and tightness – can cut electricity use by well over ten per cent and prevent failures.
