As the demand for efficient and environmentally-friendly cooling solutions continues to grow, magnetically-based cooling systems have emerged as a cutting-edge technology. At Bakker Magnetics, we are proud to offer innovative cooling solutions that utilize the power of magnets, providing our clients with the most advanced and effective cooling options available.

Magnetocaloric effect

A great example of magnetically-based cooling systems is the magnetocaloric effect, which refers to the thermal response of certain materials to variations in a magnetic field. Researchers at the Federal University of Santa Catarina are using this effect to develop an energy-efficient magnetocaloric wine cooler that has the potential to revolutionize the (wine) cooling industry.


Hallbach magnets are a crucial part of this technology. This powerful arrangement of magnets create a strong magnetic field, ideal for a wide range of applications, including magnetic cooling. This is where our knowledge and experience really come into play. Configuring Hallbach magnet arrays can be a challenging process due to their exceptionally strong magnetic forces. The strength of these magnets requires careful consideration and planning to ensure that they are configured properly for optimal performance. Our team of experts at Bakker Magnetics has the knowledge and experience needed to tackle even the most complex Hallbach magnet configurations, delivering top-notch results every time.

Researchers are breaking ground with their wine cooler

At the Federal University of Santa Catarina, researchers at POLO (Research Laboratories for Emerging Technologies in Cooling and Thermophysics) are breaking new ground with their energy-efficient magnetocaloric wine cooler. Unlike traditional refrigeration methods, this innovative wine cooler uses the magnetocaloric effect, which is the thermal response of some materials to magnetic fields. By harnessing this effect, the cooler can lower the temperature of the wine cabinet without the use of flammable or environmentally harmful substances.


The Active Magnetic Regenerators (or AMRs) play a vital role in this cutting-edge technology, generating the refrigerating effect alongside the magnet. Working together, they perform a similar function to that of a compressor in a conventional refrigerator. During the magnetic refrigeration cycle, water is used to remove heat from the wine cooler cabinet, effectively lowering its temperature. The AMR itself consists of a porous solid metal that cools down and heats up the flowing water by undergoing a temperature variation under the action of the magnetic field. The end goal of this innovative project is to achieve temperature and cooling capacity specifications that are on par with a 31 bottle wine cooler, all while maintaining an energy consumption level that is compatible with that of a conventional appliance.
