Building upon world-leading research of TU Delft, our patented magnetocaloric material based on Mn-Fe-P-Si heats up when exposed to a magnetic field and cools down when the magnetic field is removed. This Magneto Caloric Effect (MCE) forms the foundation of magnetocaloric cooling and heating technology.

Magneto’s patented material is the only known composition that does not contain rare-earth elements, is non-toxic, and has the widest operating temperature span ranging from -80°C to 200°C.

Abundantly available low-cost raw materials and our special composition enable, for the first time, mass production of magnetocaloric materials for heating and cooling applications at a competitive cost price, unlocking a vast global market.

Magneto’s patented 3D printed magnetocaloric shapes allow highly efficient heat transfer to our specially formulated, environmentally friendly water-based heat transfer fluid. The special geometry achieves high efficiency by reducing the resistance of the water flow and optimizing the geometry with respect to the direction of the magnetic field to avoid demagnetization effects.

Each 3D printed heat exchanger generates a temperature span of about 2°C. The heat exchangers are stacked and assembled into a cascade that is customized to the dimensions, temperature span, and heating/cooling power desired by the customer. A temperature span of 40°C, therefore, requires a cascade of about 20 individual heat exchangers.

Magneto’s active magnetic regenerator (AMR) is the key component and heart of any magnetocaloric heat pump system. A cascade of magnetocaloric heat exchangers, customized to the required temperature span and heating/cooling power of the heat pump, is assembled into the AMR.

The change in temperature for heating and cooling applications is generated by placing the AMR in a rotating magnetic field, magnetizing and demagnetizing the magnetocaloric heat exchangers cascaded inside the AMR.

The water-based heat transfer fluid flows through the AMR and changes its temperature by absorbing or releasing the heat of the heat exchangers. The AMR creates a hot and a cold fluid cycle, which are used in heat pump applications for either heating or cooling. Note also that the AMR can easily switch between heating and cooling operations offering new opportunities in the design of innovative heating and cooling systems.

Magneto has developed a special recipe for the water-based heat transfer fluid to protect our magnetocaloric heat exchangers composed of Mn-Fe-P-Si from corrosion, ensuring a long lifetime for our products.
