Scheffler Dish System

High‑Temperature Solar Concentration for Steam, Cooking & Industrial Heat

A fixed-focus parabolic concentrator adjusts its mirror curvature seasonally and rotates on a single axis to keep a stationary focal point—a major advantage in steam and cooking applications

Technical Highlights

• Reflector Size: 8 m² – 80 m² (commonly 16 m² and up to 640 m² in large installations) Concentration Ratio: Approximately 120–150×
• Operating Temperature: Up to 350 °C;
• Steam Pressure: Typically, 4–10 bar for cooking systems; 6–8 bar common in large community kitchens
• Thermal Output: ~6–8 kW for 16 m² unit; large systems (e.g., 640 m²) generate ~2 600 kg/day of steam
• Reflectivity & Efficiency: Reflectors reach ~92–95% reflectivity; optical efficiency up to 59%–67% in modern units
• Structure & Tracking: Mild‐steel framework with glass mirror strips; manual or semi-automatic single-axis tracking

Why Choose Scheffler Dish?

• Fixed Focal Receiver: Safe cooking/boiling with stationary vessels—no hot-moving parts
• High-Temperature Capability: Steam up to 8–10 bar and heat exceeding 350 °C—ideal for industrial and institutional use
• Scalable Deployment: From single-dish units to arrays serving thousands—with significant LPG/wood fuel savings
• Proven & Cost-Effective:

Key Applications

• Institutional and industrial steam cooking (hostels, temples, schools)
• Solar sterilization, pasteurization, and drying
• Hybrid thermal systems combining solar and biomass or LPG
• Potential use in small-scale CSP plants and thermal energy storage
