Aero & Defense

Modern defense and aerospace platforms rely on robust digital infrastructure, which in turn depends on power, connectivity and cooling. If any one of them fails, the mission fails.

Weight and volume are critical: compact cooling systems save cost, weight and space, from ground vehicles to aircraft.
Harsh environments, from the battlefield to high altitude, demand reliable cooling without power, moving parts or maintenance.
Low acoustic signatures enhance stealth by reducing noise emissions and improving platform survivability.

Why do engineers choose Calyos?

Engineers across different industries are solving similar challenges using passive, two-phase cooling technologies.

Cost & Complexity

Self-regulating systems that require no controls, operating only when heat is applied.

Thermal Performance

Vaporization inherently has an extremely high heat transfer co-efficient.

Weight & Volume

Remove the need for pumps, connectors, valves and controls to save valuable space.

Energy Consumption

Two-phase is inherently passive, harnessing the latent heat of vaporization.

Safety

Dielectric fluid and self-regulation removes the risk of short-circuits and failure.

Typical Applications

Regardless of the market segment the same applications require cooling.

Power Electronics

Power Electronics

  • Inverter
  • On-Board Chargers
  • Converter

Advancements in nano-technology (including GaN & SiC) are creating components with ever increasing heat density, combine this with the need to reduce packaging weight and volume and power electronics are increasingly difficult to thermally manage.

Embedded Electronics

Embedded Electronics

  • Inverter
  • On-Board Chargers
  • Converter

Electronics are now embedded in almost every application, from vehicles and aircraft to industrial equipment and telecom infrastructure. As components shrink and power density rises, they produce more heat in tighter spaces where traditional cooling struggles.
