Overview
The Turgo is an impulse turbine where the jet strikes the runner plane at an angle, allowing higher flow and higher specific speed than Pelton at the same head — in a smaller, more compact machine.
Ideal for rural electrification and small agro-industrial plants, TC Turgo units ship complete with nozzle, needle and deflector, and share parts commonality with our Pelton line for easy maintenance.
Typical Applications
- Medium-head streams (20–300 m net head)
- Rural mini-grids from 100 kW to 3.2 MW
- Agro-industrial and small factory power supply
- Compact powerhouse layouts with limited space
Technical Specifications
| Net head | 20–300 m |
|---|---|

In-House Machining & Quality Control
Every runner, shaft and part is machined and inspected in our Zhangjiajie factory — 30,000 m² of land with 14,000 m² of production floor — critical tolerances are never outsourced.

Frequently Asked Questions
What site data do you need to quote a turbine?
Net head and flow are the two essential figures — site location and grid connection point help us refine the layout. Send whatever you have: our engineers will tell you within 48 hours what the free preliminary study requires.
Do you supply spare parts after commissioning?
Yes. Runners, shafts, bearings, nozzles, needles, deflectors, seals and governor parts are manufactured on plan and supplied throughout the plant’s life.
Can you support installation and commissioning on site?
Yes. TC supplies and supervises the electromechanical installation, and HIER Madagascar provides local execution, O&M and logistics across Sub-Saharan Africa.
