Siemens AG has released the Universal Vacuum Air Collector (UVAC 2010), a new solar receiver designed to increase thermal heat production in parabolic-trough power plants.
The UVAC 2010 features extremely high solar absorption, reduced heat loss and an enlarged active area, offering solar field developers significantly increased revenues and reduced operating costs, the company says.
The UVAC 2010 features improved emissivity as a result of technological advances in the sputtered selective coatings, as well as an improved active-area-to-length ratio, which enables greater solar exposure of the receiver and a proportionate increase in absorbed energy. Its superior heat-loss levels – below 9% – provide developers with greater efficiency, the company adds.
