Almost any energy requirement -exept heavy industrie- can be met with small and large systems of these types.
But the pictures only show examples. there is more
KESA is a specialist in optimizing the energy consumption of production systems.

Our service offering targets both and welcomes clients with new and older production systems. It is often crucial that the thermodynamic gradient of the various processes is recognized and used.
The example clearly shows how the energy flows of several processes can be intergrated sensibly in such a way that the energy is used to the maximum extent: the warmer process feeds the colder process.
