The Isomorph solar-air heat exchanger is as revolutionary as the Linear Mirror: it provides air at temepratures up to 200 °C at a high efficiency, thanks to a new kind of selective surface.


The new solar-air heat exchanger is at high temperatures as efficient as the solar-water heat exchanger at much lower temperatures: 

For its operation, the solar-air heat exchanger uses a ventilator, which normally runs at a power of less than 100 W, the hot air is transported in tubes with typically 12 cm diameter – the system is therefore very easy to use.

Conventional solar-air heat exchangers o not reach high temperatures. Our solar-air heat exchanger is ideal for many kinds of industrial applications.

In this application, the solar-air heat exchanger provides hot air for a roasting device for biomass.
