Are you facing some of these challenges?

Engineers across different industries are facing similar challenges as they look to resolve each thermal problem they face.

Cost & Complexity

Long, complex lines and a complex array of connections and control valves.

Thermal Performance

New electronics are smaller and more powerful due to user demands.

Weight & Volume

Larger pumps and longer lines add weight and volume reducing efficiency.

Energy Consumption

Increased pump requirements due to additional pressure drop and increased flow rate.

Safety

Electronics now control all safety measures plus, water poses risk for short circuits.

Two-phase can solve these problems.

Calyos' two-phase cooling systems deliver viable, cost competitive solutions to the challenges engineers are facing.

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.
