Calios Space Cooler is funded for terrestrial outlets

Ten years after its inception, Jumate has raised 4.4 million euros with its first commercial product. The coolness of the satellite invites itself to Earth.

For the Calios Company, it is a fundraiser that makes it possible to move forward on a commercial level. Jumet-based company publishes L’Echo That raised just 4.4 million euros. The company’s shareholders include Sambrinvest, the SFPI, Invest for Jobs, Investment Fund for Industrial Diversification of Charleroi (Fidic). Or even Finindus.

The technology derived from the space sphere of Callus is enticing on paper. The company develops durable cooling systems that do not require electricity to operate. “We use the energy generated by the material,” explained CEO, Antoine de Riel. In Jargon, the technology is called “two-phase cooling” or “passive two-phase cooling”.

The latter came from the cosmic universe, where it has been equipped with satellites for some time. The challenge was to adapt it to the terrestrial environment, especially with regard to gravity. Calios is therefore a spin-off of the Nvellois Euro hit pipeAirbus itself is a subsidiary of Defense and Space.

But the spin-off took some time. “They say it takes 3 years for a start-up, but we’re more than an old start-up,” admits De Riel.

Calios was founded 10 years ago and has gone through more complex times. At the beginning of 2021, the company had to repay a loan of 3.5 million euros and launch a bond loan of 1.5 million euros.

In addition to strategy, the challenge is to find commercial outlets for a technology that is still expensive. The cost of the technology is 20,000 euros mundane and a good part of the work of the team of 17 people is to reduce the cost.

True moment

Calyos CEO Antoine de Ryckel aims to make a profit in 2024.

After a few years of development, the next two years are a moment of truth for Calios. Tests are in their final stages and commercial products will soon see the light of day. “We’re moving from the prototype stage to mass production,” said the CEO, who works with about 20 customers and is also looking for strategic partners for production.

Aircraft hybridization, electric car batteries, data centers, data, Computer processors for high frequency trading Even in the case of nuclear power plants, there is no shortage of potential outlets for Calios.

Electric car outlets are specially highlighted. In this developed field, “The need for improved thermal solutions is increasingly critical. At the same time, the urgent need to reduce CO2 emissions means that the thermal solutions provided by Kelios are becoming essential, “says Kallios.

Twelve months to decide

Within twelve months, the boss wants to decide on the most successful areas Small series production can be done directly in the company. Otherwise, it will be a matter of tracking customers.

As of this year, a first project should be completed. However, some customers are experiencing difficulties, especially due to supply chain problems, which may delay one or the other project in Calios.

“Raised money allows us to see until 2024”,

“The money raised makes it possible to see by 2024,” said the CEO, who is aiming for a break-even in 2024 this same year.

In this business niche, Calios has no real direct European competitors. “The competitors are from Japan or the United States, but we’re actually more in competition with other technologies,” the CEO added.
