Caeli Énergie
Cooling buildings with low-carbon cooling systems made in France. Founded in Grenoble in 2020 by Rémi Perony and Stéphane Lips, Caeli Énergie is a deep-tech company serving the energy transition. energy transition, whose mission is to replace polluting air-conditioning systems air conditioners imported from Asia with low-carbon products made in France products. The company manufactures particularly compact, high-performance evapo-exchangers using an indirect adiabatic thermodynamic cycle with dew point, developed developed at the CNRS. Caeli Eénergie is supported by BPI and Ademe, and has already won over groups such as Vinci, as well as public and private building operators. Asterion has co-managed Caeli's Seed round with Starquest Capital in August 2023.
"When I first saw the product working, I thought it was magic: feeling hot 35 degrees air enter their beautiful machine before coming back out at 13 degrees and cooling the entire room to around 22 degrees, was it witchcraft or a stroke of genius? There are no tricks: it's just an old technology (dew point adiabatic) optimized via some fine Grenoble engineering (and patents) and miniaturized by experts in the field through years of testing and learning. The result is impressive, with energy consumption lowered to that of a WIFI box (in other words, not much compared with conventional air conditioning), no refrigerants and no heat being released outside."
