LHP-PE

The only 100% passive alternative to water-glycol cooling systems.
fully SCALABLE

Whether you are cooling one tiny GaN component or 12 large IGBTs we can scale our solution to meet the needs of your application, no matter the type or size.

gan & sic ready

Our systems are built for the latest high-heat flux components that can enable capabilities like ultra-fast charging. We can handle heat-flux hotspots up to 250W/cm².

ultra reliable

With no moving parts, our solutions are extremely reliable and inherently maintenance free. Therefore they are ideal for reliability critical environments.

Long lasting

We produce systems with design lifetimes of up to 40 years. This fit and forget approach comes from our technology's history in the space industry.

100% PASSIVE

The beauty of two-phase is the ability to harness the latent heat of vaporisation, using it to power the cooling system, making it the most sustainable solution.

LHP-PE

Adapt the system to your needs

No application is the same, hence each of our solutions is adaptable to your specific needs and design. Below we outline how several key parts of the solution can be modified to suit the thermal challenge you face.

The Evaporator

If you have multiple heat sources we can add extra evaporators as needed, combining them into one complete system. Calyos can also adapt the size and mounting mechanism of each evaporator to suit the component you are cooling.

The LINES

The lines join the evaporator to the condenser and they can integrate multiple evaporators in parallel if needed. Their route, direction, and length can easily be customised. Flexible sections are typically included to ease maintenance and installation.

the condenser

Calyos can use any type of condenser, be it air, liquid, or a conductive plate. The size can be completely customized to your needs and location, but of course the amount of heat being dissipated is always a factor to consider here.

USE CASES

There are thousands of use cases for our technology. Here we have selected a few typical applications. Don't be afraid if you have something different - reach out to us and we can validate the application through a feasibility study.

request feasibility study
Our solution was designed to remove 2.4kW of thermal power from the inverter and recover this energy by pre-heating the HVAC system. Our LHP-PE solution transported the heat over 4m, completely passively, proving our ability to transport heat over long distance against accelerations.

Our solution cooled 8 IGBT modules, with a total thermal power of 11.2kW. By reducing the thermal resistance of the cooling system, the client could reduce the number of IGBT modules reducing cost significantly. There are also no pumps, nor fans drastically reducing maintenance.
