From an ambitious engineering challenge to a new benchmark in cooling, BSH’s Wrocław factory is demonstrating how sustained innovation can help advance energy efficiency in white goods.
The race to develop more energy-efficient domestic appliances continues to push manufacturers into new engineering territory. For BSH’s cooling team in Wrocław, Poland, that journey has delivered a series of notable milestones, culminating in an A-25% energy-efficiency-class bottom-freezer refrigerator described by the company as its “next big thing”.
The achievement highlights the role of manufacturing expertise, product development and collaboration in advancing refrigerator technology at a time when energy consumption remains a key consideration for appliance manufacturers and consumers alike.
The journey began with a significant change to the European energy-labelling system in March 2021, when the rescaled A-to-G labels replaced the previous A+, A++ and A+++ categories for refrigerators and other appliances.
Under the revised system, the highest A rating became substantially more demanding. Products that had previously carried an A+++ rating could find themselves in lower categories under the new scale.
many experts initially considered achieving the new A class an exceptionally ambitious target.
For BSH’s Wrocław team, however, the challenge became a catalyst for further development.
Three milestones in three years
The factory’s progress illustrates how incremental advances in engineering can build towards a larger technological achievement.
April 2023: Double-A performance
Building on work by BSH’s Global and Local Development Department, the Wrocław team achieved what Pira describes as the first BSH cooling appliance combining the top A energy-efficiency class with the top A noise-emission class.
The milestone demonstrated that improvements in energy consumption could be pursued alongside quiet operation — two important considerations in the development of modern refrigeration appliances.
April 2024: A further step forward
The next milestone was the introduction of a KGN EEC model designated A-10%, representing further progress beyond the A-class threshold referenced in the post.
This achievement provided another platform for the team to push the boundaries of refrigerator efficiency.
2026: The A-25% ambition
The latest development is an A-25% bottom-freezer refrigerator, which Pira identifies as the next major milestone for BSH’s cooling business.
The progression from the 2023 achievement through the 2024 model to the latest development illustrates a sustained effort to improve appliance performance rather than treating efficiency as a one-off product target.
The engineering behind greater efficiency
Achieving higher energy-efficiency levels requires more than simply changing a compressor or adjusting a single component. Refrigeration performance depends on how the complete appliance operates as a system.
The design and optimisation of compressors, heat exchangers, insulation, airflow and electronic control systems can all influence energy consumption. Improvements in one area must be assessed alongside their effects on temperature stability, reliability, manufacturing cost and everyday usability.
The work also needs to translate from development into consistent production. An appliance must repeatedly meet its declared performance across manufactured units, making process control, testing and validation important parts of the journey.
These challenges help explain why continued progress in refrigerator efficiency depends on close collaboration between product designers, engineers, manufacturing specialists and development teams.
Why this matters for the white goods industry
Energy efficiency remains an important competitive factor in the European appliance market. Consumers are increasingly conscious of the running costs associated with products that operate continuously, such as refrigerators and freezers.
For manufacturers, more efficient appliances can help reduce the electricity required during use, although the overall environmental impact also depends on factors including manufacturing, materials, product lifespan and end-of-life treatment.
Higher efficiency targets can also stimulate innovation across the supply chain, encouraging improvements in components, insulation materials, controls and production processes.
At the same time, manufacturers must balance efficiency with affordability, durability, food preservation and the expectations of customers. The commercial challenge is to deliver measurable improvements without compromising other aspects of product performance.
Collaboration at the heart of progress
Pira’s post also recognises the contribution of colleagues across BSH’s development and cooling teams, underlining that the achievement is the result of collective work.
This is an important point for an industry in which appliance innovation increasingly depends on combining specialist knowledge across disciplines and locations.
The Wrocław factory’s progression provides an example of how manufacturing sites can contribute to broader product-development ambitions, turning demanding technical targets into practical product advances.
The next chapter in refrigeration
BSH’s latest A-25% development is another marker in the continuing evolution of domestic refrigeration. As efficiency expectations rise and appliance technologies develop, manufacturers will face further challenges in combining lower energy consumption with reliable performance, competitive pricing and attractive product design.
For the wider white goods sector, the message is clear: meaningful progress comes from sustained engineering, close collaboration and a willingness to revisit what is technically achievable.
The Wrocław team’s journey from the initial challenge of the new energy labels to its latest refrigerator development demonstrates how a long-term commitment to improvement can help move the industry forward.
White Goods Now will continue to follow developments in appliance engineering, energy efficiency and product innovation across the global white goods industry.
