It holds two photorreactors of 1 m for light-induced reactions at the multi-liter scale (10 – 40 L) as provided by Ecosystems, S.A. designs. Their respective solar collectors (AoSol) possesses a geometry of compound parabolic collector (CPC) optimized for directing the light towards a coaxial or planar surface. A small electrical drive moves the fluid through a closed circuit. The reactors are provided with temperature probes, flow control valves and a fiber optics spectrorradiometer.
