Company Overview
Calyos is a Belgian technology company that designs and manufactures advanced passive two-phase cooling systems for electronics. A spin-out from Euro Heat Pipes SA, the company adapted space-grade thermal management technology for terrestrial applications. Calyos's core technologies include loop heat pipes (LHP), micro-channel heat pipes (MCHP), and pulsating heat pipes (PHP), which provide cooling without the need for pumps, making them reliable and maintenance-free. The company's solutions are designed to be sustainable, using a dielectric, green refrigerant and harnessing waste heat to power the cooling process. Calyos primarily serves the e-mobility, computing (including data centers and personal computing), and renewable energy markets, addressing the increasing thermal challenges posed by electrification and data processing. The company is headquartered in Charleroi, Belgium, and serves a global client base.
