lhp-ee

The most flexible, high performance, 100% passive cooling solution on the market.
no water no risk

Calyos uses a dielectric, safe, and green refrigerant inside our systems. This removes the risk of short circuiting expensive equipment if the lines are damaged.

easy to adopt

Combining standard components with custom lines to suit your mechanical design ensures our system can be adopted on both new or existing hardware.

fit & forget

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 technologies 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.

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 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 or size of condenser, be it air, liquid, or a conductive plate, including recovering the heat for another application. Our design can access remote cold sources to improve performance. The amount of heat dissipated is a factor to consider here.
