Indian-Made Mini Hydro Crossflow Turbine – 5 kW to 1 MW | Low-Cost, Robust & Easy Maintenance for Remote & Off-Grid Sites | MNRE Small Hydro Compliant

Indian-Made Mini Hydro Crossflow Turbine

Overview

Key Features

• Turbine Type: Crossflow (Banki-Michell Impulse Turbine)
• Head Range: 5 meters to 200 meters
• Flow Rate: 0.02 m³/s to 1.5 m³/s
• Simple Design: No precision blades; uses cylindrical runner with fixed vanes
• Self-Cleaning: Tolerant to silt, leaves, and debris—ideal for Himalayan rivers
• Low Maintenance: Minimal moving parts; no need for fine filtration
• Materials: Mild steel or stainless steel casing; galvanized or painted for corrosion resistance
• Efficiency: 75–85% (lower than Francis/Kaplan but highly reliable in harsh conditions)

Technical Highlights

• Power Range: 5 kW – 1,000 kW (1 MW)
• Speed: 300–1,000 rpm (direct or belt-driven to generator)
• Control: Manual or automatic spear valve / guide vane actuator
• Civil Works: Minimal—can be installed in open channels or simple penstocks
• Certifications: Compliant with MNRE Small Hydro Guidelines; many units BIS-tested

Ideal Applications

• Village electrification under GOI rural energy programs
• Agro-processing units (flour mills, oil expellers, cold storage)
• Eco-resorts & homestays in remote hilly areas
• Irrigation canal drops and forest department water channels
• Micro-grid projects under Saubhagya or DDUGJY extensions
