Frequently Asked Questions
Where is Calyos located?
Calyos is located in Wallonia, Belgium.
What industries does Calyos operate in?
Calyos operates in the following industries: deeptech, thermal technology, defencetech, industrialtech.
When was Calyos founded?
Calyos was founded on 2026-04-15.
What is the primary function of Calyos cooling technology?
Calyos designs and manufactures passive, two-phase cooling systems for electronic components. These systems dissipate heat by harnessing the latent heat of vaporization, allowing components like processors, batteries, and power electronics to remain within safe operating temperatures without the use of pumps or moving mechanical parts.
What are the main advantages of choosing Calyos passive cooling solutions?
The primary benefits include high thermal performance, zero maintenance due to the absence of pumps, increased system reliability, and lower energy consumption. Additionally, the systems are quiet, utilize dielectric fluid to eliminate the risk of short-circuits from leaks, and are 100% recyclable.
Which industries does Calyos serve?
Calyos targets markets with high thermal management demands, primarily including e-mobility, data centers, computing, renewable energy, and defense.
How does Calyos technology work without using pumps?
The technology uses a closed-loop system where a working fluid absorbs heat from a component and evaporates. This vapor naturally travels to a cooler section of the loop, where it condenses back into liquid and returns to the heat source via capillary action or gravity, depending on the specific technology used, eliminating the need for external mechanical pumping.
