Calyos is a Belgian company that develops passive two-phase cooling systems for high-power electronic components, targeting markets such as electric mobility, energy, and computing. Their approach seeks to absorb heat through vaporization and move it to a larger surface for dissipation, enabling reliable and sustainable cooling without active components. The firm traces its roots to the space sector, drawing on experience from the European Space Agency and Euro Heat Pipes, the latter of which commercialised the same space-cooling technology. Calyos is based in Jumet, in Wallonia, Belgium, and operates within the industrial machinery manufacturing sector. In 2026 it announced partnerships with Valeo and with Noctua, signaling increasing collaboration with automotive and aviation-oriented partners. NATO's DIANA programme has validated Calyos' cooling concepts.
