Tower & Parabolic Trough plants are the most common plants worldwide. ECILIMP Termosolar has developed a New Generation of their Cleaning Tools under the MinWaterCSP project (Minimized Water Consumption in CSP plants). This project solution has been entirely developed in Spain and tested both in Spain and Morocco.
The optimization of the Cleaning Water consumption in CSP Plants is a huge effort considering these plants are increasing their mirror surface in the meantime they maintain or reduce the Cooling Water consumption.

So, the goal for the traditional cleaning activities has been focused in two different paths:
a) Reduce the water consumption itself thanks to improving the hardware and software
b) Improve the cleaning results to allow a reduction of cleaning cycles
These traditional cleaning technologies has the advantage that they are reliable and they can be implemented anywhere in the world.

So, ECILIMP Termosolar bets for these developments in order to provide the best cleaning services wherever a client requires warranting an improvement of their Average Cleaning Factor, using the most optimized amount of water and always regarding the scratching effects and the mirror integrity.
HELIOS – the Heliostat Cleaning Solution
HELIOS has been entirely designed since it is available in two versions:
- HELIOS B: 4wd (4 wheel drive) version with a water tank capacity of 10.000 l
- HELIOS B plus: 6wd (6 wheel drive) version with a water tank capacity of 15.000 l

Both of them are able to clean more than 200 heliostats per shift both in brushes or spray. They incorporate a new cleaning algorithm, called Smart Cleaning, which calculates the exact amount of water that the user needs regarding the Cleaning Factor (CF) previously to cleaning.
Also, it always maintains verticality independently of the slopes in the road. So, a better water use is performed.
CURVE is the final solution!
Using the best accomplishment to the Parabolic Trough ever, CURVE always spend the optimized amount of water!
Also, thanks to the Smart Cleaning Algorithm, the water use is always adapted to necessities as well as its new structure covers the 100% of the surface of the Parabolic Trough.

MinWaterCSP GOAL Accomplished!
One of the main goals of the MinWaterCSP is the reduction in a 25% of the Cleaning Water use.
The technology developed under the Work Package “Cleaning Activities” has achieved this goal since ECILIMP has achieved a total of reduction of 25% for Sprays tools and 35% for brushes tools.
Main results:
- Average CF after Brushes: 98,85%
- Average Water Use with Brushes: 0,45 l/m2
- Average Water Use with Spray: 0,65 l/m2
