STELLAR -
Magnetic Cooling, Superconducted.
WHY SUPERCONDUCTORS?
Material x Magnetic Field = Performance
The magnetocaloric effect is governed by two parameters: material and magnetic field. Our LaFeSi material is optimised and mass production-ready. To unlock its full potential, we need higher fields. Superconducting magnets get us there without compromising size and weight.
Undeniable impact
At 5 Tesla, the magnetocaloric cooling power density is over 100x greater than at 1 Tesla.
Using superconducting magnet technology, STELLAR is unlocking the full potential of magnetic cooling.

FAQ
Why are higher capacities needed?
Cooling accounts for around 10% of global energy demand. By 2050, that demand will triple. Whether it is keeping homes liveable, factories productive or data online, cooling is critical infrastructure.
The shift to refrigerant-free cooling has begun, and adoption in low capacity applications is accelerating, but marks just the start. To truly enable the shift, refrigerant-free cooling must scale into high-capacity applications consuming the most energy: data centres, industrial process cooling, building HVAC, and more.
Can I buy STELLAR?
STELLAR is not yet commercially available, but is available for joint development projects.
If you are a cooling supplier or operator looking toward the future of cooling, then STELLAR is for you. Get in touch to discuss collaborations and projects working toward high-capacity cooling goals or compare expected performance with your current set up, here.
Are permanant magnet systems being replaced?
No. Permanent magnets are well-suited to lower-capacity applications and will continue to power our ECLIPSE system platform. To reach the field strengths required for high-capacity industrial and commercial cooling, permanent magnets hit a practical limit.
STELLAR addresses this with superconducting magnets, which deliver the higher fields needed without the weight and footprint trade-offs.
