When culinary art meets cooling technology – our QOOL Box in cooperation with Johann Lafer and Ballerina-Küchen

This year's Kitchen Mile in Rödinghausen was a very special moment for us: the QOOL Box was presented as the centerpiece of Ballerina's new Lafer kitchen. A project that demonstrates what's possible when technology, design, and culinary arts come together.

The QOOL Box as the heart of the Lafer kitchen

Our QOOL Box plays a central role in this concept.
As part of the “Lafer by Ballerina” collaboration, it was integrated into the kitchen to rethink flexibility, freshness, and efficiency.

The box operates completely without electricity and maintains constant refrigerator or freezer temperatures for up to ten days. This makes it ideal as an additional cooling unit—for example, when guests arrive or more space is needed.

"When you have a lot of guests, the refrigerator is often full. The box creates additional cooling space."

– Heidrun Brinkmeyer, quoted in Sven Hauhart, NW , 2025

The QOOL Box originated in medical technology—proof that the highest precision and everyday practicality go hand in hand. Thanks to modern vacuum insulation panels and special temperature elements, the temperature remains constant.

“If you put ice cream in the freezer, you can "You might end up killing someone. That won't happen again with the box."

– Johann Lafer, quoted in Sven Hauhart, NW , 2025

Design meets functionality

The Lafer kitchen demonstrates how refrigeration technology and kitchen design can work together. In addition to its functionality, the QOOL Box impresses with intelligent details such as automatic carrying handles, recessed grips, and hygienically easy-to-clean surfaces.

It fits perfectly into Ballerina's design concept – and into the philosophy of Johann Lafer, who places value on well-thought-out processes and clear structures.

A look into the kitchen of tomorrow

Our collaboration with Ballerina Kitchens and Michelin-starred chef Johann Lafer demonstrated how seamlessly our electricity-free cooling technology can be integrated into modern kitchen concepts – functional, aesthetic, and with real added value in everyday life. Together, we want to demonstrate what innovation in the kitchen looks like when quality, sustainability, and passion for cooking come together.

We at QOOL Products are proud to be part of this development – and to be actively shaping the kitchen of the future together with strong partners: for more enjoyment, efficiency and quality in everyday life.
