Who We Are
Calyos is a leader in the design and manufacture of two-phase thermal management systems. Building on our heritage from Euro Heat Pipes (EHP) and their space technology expertise, we specialize in innovative cooling solutions that tackle the thermal challenges of tomorrow.
What We Do
We engineer advanced cooling technologies, including loop heat pipes, micro-channel heat pipes, and pulsating heat pipes, to optimize thermal performance across a variety of applications. Typically these include: power electronics, processors, and batteries, but we don't stop there we are continuing to develop and produce fully customizable solutions for other specific needs, for example e-motors and fuel cells.
Where We Operate
Calyos is headquartered in Charleroi, Belgium, where our engineering and production teams work side by side in a state-of-the-art facility. From this base, we serve a global clientele, providing our cutting-edge solutions across North America, Asia, Europe, and South America.
When We Started
Calyos was incorporated in 2014 as a spin-off from Euro Heat Pipes (EHP), which was established in 2001 and has become a major player in the European satellite market. Since then, Calyos has been adapting and evolving EHP's space-grade cooling technologies for terrestrial applications.
Why We Matter
Our mission is to lead the industry towards adopting the most effective and sustainable thermal management solutions. We aim to address the most pressing thermal challenges in the data-driven and electrified environments of today, leveraging passive cooling technologies to achieve superior efficiency and environmental stewardship.
How We Succeed
Our success is driven by our commitment to four core values:
1. Applied Knowledge - Transforming deep technical expertise into market-ready solutions.
2. Better Together - Emphasizing collaboration with all stakeholders to enhance our collective success.
3. Inherent Flexibility - Adapting our solutions and practices to keep pace with evolving market demands.
4. Continuous Research - Persistently innovating to maintain our leadership in thermal technology.
