The features of the Inclined jet Hydro Turbines (Turgo Turbines):
They operate in a head range of 40 meters to 300 meters and are primarily used for electrical power production. The power output ranges from 100KW to 1250KW.
* Its nozzle has a 22.5¡ãangle with the runner rotation surface.
* The runner is heavily pushed by water from pressure pipe that is switched to high speed jet flow through spray nozzle, imposing the runner in inclined direction.
* The runner works by water flow entering one side of vane and coming out from its other side, pushing the runner to rotate, the runner then drive the generator through coupler to produce electricity.
* It can reliably operate with simple structure, easy inspection and maintenance.
* Inclined jet Type turbine has as simple structure as the pelton turbine, reliably operate with simple structure, easy inspection and maintenance.
* It has the merit of high specific speed, wide application range, easy to coupling and direct connation to the generator.
Addnew's inclined jet hydro turbines (turgo turbines) is one type of impulse turbine. It is well developed and widely used in mountain area.

The features of the Francis Hydro Turbines (Mixed Turbines):
They operate in a head range of 20 meters to 450 meters and are primarily used for electrical power production. The power output ranges from 160KW to 20000KW, Runner diameters are between 0.5 and 2.5 meters. The speed range of the turbine is from 150 to 1000 rpm.
* Excellent peak efficiency.
* High efficiency also at partial water flow down to about 50%.
* 2 or 4 bearing gen-set arrangements.
* Bearings rated for more than 100 000 hours of operation.
* Guide vane control electrically or hydraulically.
* Complete range of specific speeds for runner design allows optimized matching to synchronous speed.
* Compact design and low maintenance requirements by rigorous selection of best suited materials and proper design.
Francis hydro turbines (mixed turbines) is used for middle & high water head with middling level of water flow.

They operate in a head range of 2 meters to 30 meters and are primarily used for electrical power production. The power output ranges from 35KW to 8700KW, Runner diameters are between 0.8 and 3.3 meters. The max efficiency is up 89%.
* It has large overflowing, good flow characteristic and high efficiency etc. merits.
* The runners are fixed or can adjust manual the efficient turbine of this kind can produce a large quantity of water flow which passes unimpeded.
* All are horizontal type, the water enter into the turbine along the axial direction.
* Compared with vertical axle flowing type units, the factory building is little in excavating amount, and hydropower station water conservancy project investment can save 10%- 20%, equipment investment saves 5%- 10%.
The turbine is powered by water flowing through the wicket gate. This gate can be controlled to determine the rate of flow through the turbine and therefore the amount of power generated. The turbine is attached by a shaft to an electric generator.

They operate in a head range of 100 meters to 1000 meters and are primarily used for electrical power production. The power output ranges from 200KW to 20000KW, Runner diameters are between 0.13 and 5.81 meters. The speed range of the turbine is from 250 to 1000 rpm.
* The runner works by being heavily pushed with jet flow that is switched through injection nozzle from high-pressure pipe. The feature is that is works by impulsing the runner to rotate with kinetic energy of water flow, and the jet center of nozzle and the runner are in the same plane.
* It is divided into vertical type and horizontal type two kinds. Horizontal type each has 1-2 runner, each runner has 1-2 nozzle, vertical type each has only one runner, each runner has 2-4 nozzles.

Applicabletoanyhydropower siteswith high water-headover 50m;
Workable for smallwaterdischargespeedless than 1 m3/s;
Whole generating set as one-unitpre-installed insideonecontainer;
Customizable foranyinstalledunit-capacityless than 1,000kW;
Bothfor off-grid (isolated)and grid-tied operation;
Suitable not only for the main cities, towns, villages within the reach of the power grids, but also for small hydropower sitesin remote and mountainous areas, which far away from the power grids.
Important Reminding: The roads to the hydropower site should be suitable for 40ft-container-load shipping.
Unique Features and Advantages: All the equipments are pre-assembled, pre-commissioned, pre-installed andtotallyincluded inone 40ft container, which replaces the powerhouse;So itgreatly reduces the impact of civil works on the site. Easier preparationrequired for installation and much less installation period (4 weeks or less): Less construction costs and shorter con struction period,Less occupation of land;
Successful Sample Projects:
1) Shuanglong Containerized Micro Hydro Power Generating Systemin Jinhua, Zhejiang, China Total Installed Capacity: 160kW.
2) Containerized Micro Hydro Power Generating System in a countryside area, Wenzhou, Zhejiang, China Total Installed Capacity: 300kW.
