Siemens' 6G receiver

The announcement has been made at the SolarPACES 2012 conference in Marrakech. The UVAC 6G is the new upgraded receiver for parabolic trough with which Siemens expect to reduce the CAPEX and OPEX by up to 2.5 percent.

“Based on our continuous R&D as well as our many years of field experience, the UVAC 6G expands the potential of solar thermal power plants with increased power generation capabilities,” said Dr. Shmuel Fledel, CEO of Siemens Solar Thermal Energy Business Unit. “The UVAC 6G is also an extremely reliable product, which will provide our customers with many years of uninterrupted performance.”

The UVAC 6G is Siemens' sixth generation solar receiver, which, according to Siemens, offers higher durability and use improved coatings to absorb the maximum solar energy to heat the HTF (heat transfer fluid) flowing inside. Patented getter bridge technology effectively eliminates hydrogen in the receiver tube before any vacuum loss can occur and does not require cost-intensive workaround solutions for maintenance.

Siemens bought Solel, a receiver manufacturer, in 2009 for $418 M and since then, the company has improved the receiver performance from the Solel UVAC 2008 model to the current commercially available UVAC 2010 and the brand new 6G.

Siemens has become a worldwide provider of a complete solution for solar field in parabolic trough plants, the company offers its SunField LP, a package comprised by trough assemblies, reflector and receivers.
