AboutOur technology will save you money

We are a team that had an idea in 2015, an idea that has grown into something bigger. We are ready to tell the world of a device that generates green energy!

We have created a range of equipment that recovers thermal energy from waste water, which you can use either to cool the interior of your building, or to accumulate heat in a storage tank whenever energy costs less, or is available from the sun.

Our team includes doctors of science, experienced practitioners, and programmers, capable of combining a wide variety of technologies in a single system.

We make technologies that help the world become a better place! We’ve started with Latvia and we aim to reach the entire world.
