Highly efficient and sustainable refrigeration based on solid state Magnetic Cooling Device

Cooling and refrigeration account for 7.8% of global greenhouse gas emissions and 20% of electricity demand. The standard refrigerant F-gases have a tremendous global warming potential (GWP) and are being phased out in the EU. Available alternative gases are either toxic or explosive, posing serious issues for their applicability.

Magnotherm has developed the first industrially feasible refrigeration unit based on magnetic cooling technology that uses a specific class of material and alternating magnetic fields. This is achieved thanks to a patented process to mass produce highly performant, stable and cheap magnetocaloric materials using abundant, noncritical materials; and to interdisciplinary backgrounds and world-leading research resulting from TU Darmstadt.

Magnetic cooling implements a solid state cooling cycle using no refrigeration gas, with 0 associated GWP, no risk to the environment and no issues of flammability. It is x3 more efficient and achieves 40% electricity savings.
