About Us
Parabolic Technology Industries, LLC (“PTI”) is a new Texas corporation that was formed to be a special purpose organization to conduct parabolic mirror turbine projects, with new and innovative technology, in nations with a high index of sunlight and a low index for cloudiness. PTI is the successor to Global Turbine Power Sources, Inc. which was formed in 2010 by a team of engineering, project construction, and legal professionals to engineer, procure, and construct traditional gas fired power plants throughout the world. Today, many of the team members of GTPS, Inc are now either owners, contractors, or principals in PTI.

Full Process
Salt Explanation
The Molten Salt eutectic mixture, 60% NANO₃-40% KNO₃. These salts are widely used as fertilizer, they are low cost and available in large quantities. Their temperature varies from 290 to 550 °C when the solar field is operating.
Nitrate salts mixture :
- Sodium Nitrate (NaNO3): 60% w.
- Potassium Nitrate (KNO3): 40% w.
Features:
- Operative temperatures: 260-550°C;
- Nonflammable and nontoxic fluid;
- Low cost fluid; – Good heat transport properties:
- High Coefficient of Heat Transfer;
- High Heat Capacity;
- High Density;
- Low Operative Pressures.
Salts Physical Properties:
- Freezing Temperature: 238°C;
- Melting Temperature: 221°C;
- Heat of Fusion: 161 kJ/kg;
- Volume Change on Fusion: 4,6%.
