Central Termosolar Kathu

Kathu Solar Park is located in the Northern Cape (South Africa). It is a CSP Project (Concentrated Solar Power) Using solar panels, thermal oil (HTF) is heated up to 400 ºC; the recirculation of the HTF produces steam that feeds a turbine generating 100 MW of electricity.

To generate 100 MW of electricity with thermal oil from the solar field, the recirculation of a very relevant volume is required. Unitecno filters have the mission of protecting the pumps and other components of the thermal oil circuit by retaining particles up to 300 microns.

Unitecno’s most outstanding scope of supply:

5 Unit 22”-300# basket filter for an operating flow of 2,100 m3

2 Unit 24”-600# basket filters for a nominal flow of 1,970 m3/h at 350ºC

1 unit 10”-300# and 20 micron cartridge filter and backwash with nitrogen, for the elimination of by-products derived from the degradation that thermal oil produces over time.
