Laitu Solar introduces new technological advancements at CSP Today Sevilla to improve the efficiency of the solar thermal power plants.

Laitu Solar, a company belonging to Grupo Dominguis, introduced three new technological solutions at the Fifth International Summit of Thermoelectric Solar Concentration organized by CSP Today Sevilla 2011, aimed at cleaning and maintaining the Cylinder Parabolic Mirrors (CCP) and to improve the effectiveness and productivity of the solar thermal power plants.

The best known solution is the automated cleaning Valent System, the only one that uses two parabolic rotary brushes and a pressurized water system fully integrated for proper cleaning of the surface of the Parabolic Cylinder Collector (CCP) and the absorber tube in solar thermal power plants. At this meeting, Laitu’s executives emphasized the advancement in automated technology solutions to clean Cylinder Parabolic Mirrors in a totally automated manner and the satisfactory results of a 20+ years aging test performed by an independent laboratory, the Technological Institute of Optics, Color and Imaging (AIDO).

On the other hand, in order to ensure the optimal performance of the solar thermal power plants, the Grupo Dominguis’ company has developed Contenoil, the only system in the market that is capable of performing loop drain in solar thermal power plants with zero risk.

This innovative solution is based on the cooling of the HTF at temperatures of 70ºC, which ”allows for the extraction, transportation, storage and injection of the HTF in any area of the solar thermal power plant and at any temperature with zero risk without the need of using nitrogen for blanketing, thus guaranteeing adequate maintenance results for up to two loops”, explains Laitu Solar’s Business Development Director.

The third proposal presented by Laitu Solar at CSP Sevilla 2011 is designed to achieve greater energy productivity. It is a system, patented worlwide, which allows for treatment and filtering of the HTF of the solar thermal power plants providing a higher quality without having to stop production.

All these advancements presented by Laitu Solar are undeniable allies of the thermoelectric sector since they improve the efficiency of the solar thermal power plants and provide extensive production benefits.
