A representative from Calyos will reach out to you to plan an introductory web call where they will explain how our technology works and demonstrate the applications and benefits of it.
Thermal management is a critical requirement across many different market sectors.
Electrification is transforming the industry and is resulting in new vehicle architectures, from battery electric to hydrogen fuel cells. Regulating the temperature of components and systems with high-performance thermal management solutions is critical in extending the lifetime of a vehicle. Calyos provides solutions in all of these sectors:

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 power electronics and processor cooling.
Calyos believes in two-phase cooling because this technology brings a clear set of benefits that ensure Calyos stands out from the competition.

Our team consists of experts in all things two-phase. We produce the majority of our systems using either Heat Pipes or Loop Heat Pipes, but our expertise does not stop there. Calyos has experience developing advanced systems for all of the following technologies.

Loop Heat Pipes are Calyos' flagship technology - they are what we are known for. They offer a significant upgrade when compared to traditional heat pipes, providing better performance, and an ability to handle very high heat flux and longer transport distances. Loop Heat Pipes also have the ability to operate against gravity, differentiating them from thermosiphons.

Traditional heat pipes are beautifully simple and provide incredibly low thermal resistances. Unlike the heat pipes you might find in your laptop or computer, Calyos specialises in advanced systems. Calyos does not use water, instead opting for a dielectric refrigerant or methanol. Calyos can implement state-of-the-art designs, including using special architecture to better distribute the heat.

micro channel heat pipe for batteries
Placed in between cells, these tiny heat pipes can assist in both warming and cooling cells. The cross sectional shape can be completely customised and these solutions are incredibly cost effective to mass produce. Using a dielectric refrigerant inside removes the risk of short circuits, maintaining Calyos' fit-and-forget reliability.

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.
