Concentrated Solar Power (CSP)
The Fresnel collector is a line-focusing system which uses individually tracked reflector rows to concentrate direct solar radiation onto a stationary linear receiver. A pressurized water circuit at 16 bars is a cost-effective and efficient way to transfer process heat at temperatures of up to 200 Â°C. For higher temperatures, a thermal oil circuit is the appropriate technology.
Industrial Solar collectors can provide process heat at temperatures of up to 400 Â°C in a power range from 100 kW to 10 MW.
The number of possible applications is nearly unlimited!
