Conventional cooling systems often use problematic gases. In this case “problematic” means extremely flammable, toxic or refers to a high greenhouse effect. Our startup of the week does without these gases in their products and uses magnetic materials instead. Timur Sirman, Co-Founder of MagnoTherm Solutions, explains today how this works exactly.
Hello Timur! Thanks for being here today. Our first question is this: What is behind MagnoTherm Solutions?
We develop and build environmentally friendly cooling units for the cooling and heating systems of the future: with magnetic materials without any problematic gases.
How does this process work?
Active metals are cyclically heated and cooled by means of a permanent magnet. This is done by the magnetocaloric effect of these active metals. They become warm when they are exposed to a magnetic field – and cold when the magnetic field is reduced. Using a water-based exchange medium, the heat and cold can be transported from the solid and made useful. For this purpose, motor, pump, valves and control elements are used.
Why is it better to dispense with gases and use magnetic materials instead?
Without the use of F-gases, flammable gases, toxic gases or other problematic gases, our system is up to 40% more efficient than the best compressor-based cooling system available today. And this is independent of the temperature stroke or temperature range. This can be achieved by individualizing the active metals. As a result, highly efficient systems can be realized even for warm ambient temperatures and small temperature strokes, with a greenhouse potential of zero.
And that in turn is better for the environment. How do you integrate it all into a business model?
Our cooling units are integrated by our customer into his cooling system and then sold to the user. Here we develop customized products for our integration partner. In doing so, we can respond very quickly and precisely to the respective needs of the user, as our standardized structure allows the active metals to be adapted to the requirements at any time.
Who do you address with your products?
In principle, we can implement cooling units with a cooling capacity between 100 W and 100 kW. The European supermarket refrigeration industry is the first sales market, as the challenges are the greatest there. However, other markets we address are IT cooling, industrial cooling and heat pumps.
What stage of development are you currently in? How mature is your product?
We are currently building the first prototype, which will have a cooling capacity of 500 W to 1kW. This year we will equip a cooling system for Food&Beverages with this. At the same time, we are in talks with development partners to build further systems.
