Protecting Europe’s First CSP Solar Power Plant

Protecting Europe’s First CSP Solar Power Plant

Andasol 1/2, Solar Millenium AG  | Spain


Concentrated Solar Power (CSP) plants operate with liquid salt, heated by sun during the day, and releasing that heat during the night or overcast periods for steam turbine operation. The liquid salt is stored in large tanks, and crystallization should be avoided at all times.


nVent designed, engineered, installed and commissioned a complete heat management system, including 10+ km of nVent RAYCHEM MI heaters, controls and power distribution panels. The MI heat tracing system is able to maintain the liquid salt above 230°C / 446°C.
