The ESC-8231 is the custom-designed collector for regions with maritime and desert-like conditions. It is equipped with a corrosion-resistant absorber, a highly selective coating to combat sea air and an optimized ventilation concept to keep out blowing sand. The ESC-8231 has been designed to withstand 150 km/h winds and 1.25 kN/m² snow loads.

The ESC-8231 is based on a minimum number of individual components and assembled on a robotic production line at ECOTHERM. Equipped with a modular mounting system, the ESC-8231 can be used for both flat-roof and on-roof installations.
