Fresnel Collector

The Fresnel Collector is a linear concentrating, solar thermal collector optimized for industrial applications. It can provide heat

at up to 400°C and operate with pressures of up to 120 bars. Besides water, thermaloil or high-temperature glycol it can also generate steam directly. Due to its modular design, the system can be scaled up from a few hundred kW to several MW.

Functional Principle

Direct solar radiation is reflected on several rows of single-axis tracking mirrors on to a stationary receiver. This consists of a highly efficient vacuum tube with selective coating. The heat is collected

in this absorber tube and fed to the application by means of a heat transfer medium. A part of the sun light reflected by the primary mirrors hit one of the secondary mirrors positioned above the absorber and is reflected from there on to the absorber.

Advantages Of The Fresnel Collector

  • Low wind load
  • Low weight
  • Simple direct steam generation
  • Low operating costs
  • High surface efficiency
  • Simple integration
  • Long lifespan
  • Floor or roof installations
  • Automatic cleaning (optional)
