Description

The Helios solar concentrating array is designed to provide a large quantity of high quality heat energy ( 3kw peak at 950°C). The Helios offers many versatile applications suitable for a village or small commercial entrepreneur.

Seen here, the Helios is equipped with a bread oven. We have developed numerous other applications for the Helios, including a roasting oven for coffee, peanuts, cocoa beans, chilies, etc, a water purifier which boils, UV pasteurizes and distills water, and a charcoal carbonizer which burns wood or biomass in the absence of air and breaks it down into liquids, gases and charcoal.

The interior of the oven seen here measures 70cm x 70cm x 70cm and reaches 300°C in about 15 minutes.
