A second two loop system have been installed in a 8 MW diesel power plant in the small island of Pantelleria. The nominal production is 5000 l/day. The system use waste heat from the refrigeration of the engines and solar heat from the solar collectors.

Main characteristics of the installation:

• Two loop system
• Thermal energy: 20 % solar collectors + 80 % waste heat
• 40 m2 solar collectors
• Waste heat recovery: Q= 10 m3/h, T=90°C
• Brine cooler
• Operation 24h/day.
• Water management protocol: regular monitoring of water temperature, conductivity, production etc
• Water intake: 35.000-37.000 ppm
