In 2014 Calyos set about achieving our mission to provide sustainable, passive, two-phase cooling solutions. Calyos is a spin-off from Euro Heat Pipes (EHP), who successfully developed similar two-phase technologies for the space industry. Initially our research and development focused on adapting the technologies for earth applications, including moving to a flat evaporator and utilising a dielectric working fluid. Calyos now produces solutions primarily targeted at batteries, power electronics and processor cooling.
Calyos believes in two-phase cooling because this technology brings a clear set of benefits to our customers
Calyos specializes in using a dielectric, green refrigerant, removing the risk of short-circuits in the event of damage.
Our products are helium tested for tightness before they leave our factory, ensuring long lifetimes and zero maintenance.
All of our two-phase technologies harness the waste heat to vaporize a fluid, using the problem to power the solution.
By being 100% passive and having no pumps it removes the most common point of failure in liquid cooling systems.
Vaporizing a fluid is an incredibly efficient and results in systems with extremely low thermal resistances.
We make applying these advanced heat pipe technologies feasible
We produce the best wick structures that provide the maximum pumping capacity (and therefore performance).
Built from real-world data we have created accurate in-house models. Plus we use standard software where possible.
Typically we use R1233zd(E), a low GWP (<1), dielectric, non-toxic and non-flammable refrigerant. Other fluids are available.
Built for small series production and prototyping it allows us to work efficiently and react quickly as it is side by side with our design team.
Experts in adapting the solutions to your application, without which the value of two-phase cooling cannot be delivered.
Calyos’ dedicated test engineers can provide advanced thermal testing of prototypes and solutions, replicating real-world scenarios.

Thermal challenges used to be resolved easily with a simple, solid heat sink. Fast forward to today and we have exhausted the design possibilities of traditional heat sinks. As electronic technology reduces in size it increases in heat density requiring more and more powerful thermal systems to dissipate this heat. With the rapid and continuing rise of electrification and data processing, thermal management of electronics faces rapid demands. In combination with the demand for sustainable, environmentally friendly solutions Calyos is in a unique position offering 100% passive thermal solutions in a market of pumped liquid cooling.
Thermal management is the most critical reliability factor for electronic components. A good thermal system extends the lifetime and increases the performance of both processors and power electronics.
Both power electronics and battery cooling are critical to the speed and efficiency of a vehicles charging time. Cooling affects both components inside the vehicle and the charging infrastructure itself.
Waste heat from data centers is typically released into the ambient air. Heat recovery provides the opportunity to heat greenhouses or residential buildings, reducing the data centers environmental impact.
Typically EVs use up precious energy to power their cooling systems. Switching to passive cooling can save this power for the e-motor increasing the range of any type of hybrid or full electric vehicle.
