PT-Series High-Efficiency Parabolic Trough Solar Collector (PTSC)
The PT-Series is the premier solution for medium-to-high temperature solar thermal utilization. Developed by CSP Holding Group, it features advanced concentration ratios that boost photothermal efficiency to 3.5x that of traditional PV. Engineered for industrial steam, oil recovery, and CSP power plants, it boasts a 30-year operational lifespan.
1. Proprietary Glass-to-Metal Sealing Holding over 60% market share. Our proprietary sealing process withstands thermal shocks from -50°C to 550°C, ensuring the vacuum integrity of the receiver tube for over 30 years.
2. High-Transmittance AR Coating
Cover tube solar transmittance ≥96% with a 6.5H hardness. It performs excellently in acid salt spray and damp heat tests, delivering 3.5% higher efficiency than industry standards.
3. Advanced High-Vacuum Coating
Absorptance (α) ≥0.955 and emittance (ε) ≤0.05 (at 100°C). This significantly reduces convective and radiative heat loss, enabling high-efficiency collection in all weather conditions.
4. Precision Smart Tracking System
Features a tracking accuracy of ≤0.1°. Equipped with automatic wind protection, the system resets during extreme weather (high winds/snow), increasing overall system efficiency by 2%.

[ Wide Applications]
Low Temp (40-80°C): Municipal heating, hotel hot water systems, and swimming pool heating.
Medium Temp (80-260°C): Industrial process steam for textiles, food, chemicals, and timber drying.
High Temp (>260°C): Concentrated Solar Power (CSP) and solar-driven desalination.
[ Economic Analysis & ROI]
Based on Life Cycle Cost (LCC) analysis over 30 years, the total cost of this system (including installation and maintenance) is only 1/5 of natural gas and 1/10 of electric heating systems. The typical payback period is 3-5 years.
