The TiNOX® energy surfaces ensure a high absorption of sunlight and low emissions of thermal radiation. The combination of these durable characteristics allows an efficient use of solar energy and minimum heat loss at the same time. Its ability to behave differently towards different forms of radiation is optimized for the working temperature of solar collectors (approx. 100 ° C) and it allows TiNOX® products to collect up to 50% more energy than non-selective surfaces.
