Gilkes Crossflow Turbine – Robust & Debris-Tolerant Hydro Solution for 5 kW to 2 MW | Low-Head, High-Reliability | UK Engineering, Global Deployment

Gilkes Crossflow Turbine

Overview

Key Features

• Turbine Type: Crossflow (Banki-Michell Impulse)
• Head Range: 5 meters to 200 meters
• Flow Rate: 0.02 m³/s to 2.5 m³/s
• Debris Tolerance: Open-runner design allows leaves, twigs, and silt to pass through—no fine screening needed
• Self-Cleaning Action: Water flows through the runner twice, reducing clogging
• Materials:
  • Runner: Stainless steel or hardened alloy
  • Casing: Mild steel with marine-grade paint or galvanized finish
• Efficiency: 75–85% (stable across wide flow variations)
• Low Maintenance: Few moving parts; ideal for remote, unattended operation

Technical Highlights

• Power Range: 5 kW – 2,000 kW (2 MW)
• Speed: 300–1,200 rpm (direct or belt-driven to generator)
• Control Options: Manual spear valve or automated actuator
• Civil Works: Minimal—suitable for open channels, simple penstocks, or retrofitting existing weirs
• Certifications: ISO 9001, IEC 60193 (performance testing), CE Marked

Ideal Applications

• MNRE Micro/Mini Hydro Projects (up to 2 MW)
• Irrigation canal drops (e.g., Narmada, Godavari, Cauvery systems)
• Agro-processing units (sugar mills, rice mills, cold chains)
• Eco-tourism resorts in Uttarakhand, Himachal, Northeast
• Forest department water channels and tea estate runoff systems
