TECHNOLOGY OVERVIEW

Global warming is accelerating and credible solutions in refrigeration are struggling to emerge. Aware of the enormous energy and environmental footprint of thermal production in the world, the technology owner is developing magnetic cooling modules from 20 to 100 kW with low environmental impact and high energy efficiency as well as machines for conversion into electrical energy from sources of solar or lost heat (below 100°C).

The refrigeration solutions widely used today are high pressure refrigerant gas compressors. This technology, dating from the 1920s, is mature and well mastered. Its performance is modest and the refrigerants used have a negative environmental impact. Many sectors are therefore seeking new refrigeration solution that is both sustainable and environmentally friendly.

The proposed technology relates to a magnetic refrigeration device that operate without refrigerant gas. The electricity consumption is at least 50% lower than traditional refrigeration systems. It is a green technology with great potential for the environment. The technology owner also developed a device to efficiently convert low sources of wasted heat into electricity. The two technologies are very similar and rely on the same magnetic core expertise.

The technology owner is seeking partners to collaborate through various models including custom-made prototypes, co-development projects, technology licensing and strategic partnership.
