decouple cooling from climate change with air as refrigerant.

We are developing a highly efficient cooling technology which uses air as a refrigerant. Why? Our world is changing faster and more drastically than it has for all generations before us. We do not primarily see this as a threat but as an opportunity chance to actively shape more sustainable processes.

We are focused on the revolution of cooling technology to achieve temperatures between 0–40°C independently from outside air temperatures using air as a refrigerant.

customer focus

The global cooling demand accounts for 10% of the worldwide energy consumption and continues to increase rapidly. Between 2020 and 2070, almost 10 cooling systems will be sold every single second (other figures and statistics can be found at the International Energy Agency). Our technology provides the opportunity to decouple the growing electricity use and related CO2 emissions from fast increasing numbers of required cooling systems.

We are currently developing a technology that is 4 to 5 times more efficient than conventional cooling systems. In addition, we are using air as natural refrigerant – unlimited availability at no cost with a Global Warming Potential of zero (find out more about natural refrigerants at Green Cooling Initiative). The use of air as refrigerant is nothing new, but by now there is no single competitive cooling system targeting the same temperature range. Our first product will be cooling system that is designed for data centers followed by additional products in the scope of industrial and commercial applications.

Innovative fractal heat exchanger by justairtech
The core technology of our cooling system is a so-called fractal heat exchanger. 3D printing enables the realization of a  snail-like structure that offers an enormous surface for the heat exchange while keeping the dimensions of the heat exchanger compact.
