Caeli Énergie
Keeping buildings fresh with low-carbon made-in-France cooling systems. Founded in Grenoble in 2020 by Rémi Perony and Stéphane Lips, Caeli Énergie is a Deeptech company serving the energy transition, whose mission is to replace pollution-causing air conditioning imported from Asia with low-carbon Made in France products. The company manufactures particularly compact, high-performance evapo-exchangers using an indirect adiabatic dew-point thermodynamic cycle, developed at the French National Center for Scientific Research (CNRS). Caeli Eénergie is supported by Bpifrance and Ademe, and has already won over groups such as Vinci, as well as public and private building operators.
"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."
