Best Reliable Hydroelectric Equipment
Help You Own Clean Power From Water
DLLD provides full series customized solutions at reasonable price based on 30+ years designing and manufacturing experience from China
About DLLD Power
DLLD Power, founded in Dali city of Yunnan province in the year 1991, is a private enterprise specializing in the research, design, production and sales of micro hydroelectric equipment coving full series of range micro and small hydropower projects.
DLLD could design and custom make special turbines for specific site conditions. Generally, there are mostly below types turbine are used for micro hydropower system, such as Turgo turbine (or Pelton turbine) for high head sites, Tubular turbine, Francis turbine and crossflow type turbine for medium head sites, and axial flow turbine like Propeller, Kaplan, and also are suitable for low head sites. We also custom make Barrel type turbine, Submersible type turbine and Floating type turbines for special site conditions, like irrigation canals, mills, fish farms, streams and creeks micro hydropower application.
DLLD have been awarded many advanced patented technologies and commend in China, such as the “First Prize of Invention of Micro Hydro Generator for Rural Users” by Yunnan Provincial Science and Technology Commission in 1991; “Excellent Project Award of Agricultural Science and Technology” by the State Science and Technology Commission in 1996; “China Rural Energy Industry Association” in 2002. In 2002, China Rural Energy Industry Association “China Rural Energy Small Power Supply Industry Excellent Product Award”, and so on. DLLD Power passed CE certification in 2001 year and have been export to United States, Britain, France, Lativa, Peru, Chile, Indonesia, Guinea, Russia, Congo and Southeast Asia, etc other 60 countries like more than 20 years. Our products are well popular by the users because its stable performance and free maintenance.

Customers Reviews
How many power I can get from my water source?
The hydropower is obtained from actual site condition, it is up to net head and flow rate, you can estimate your micro hydropower capacity by the formla: P(w)=9.81*H(m)*F(l/s)*E(60%). (Noted the overall efficiency is normally 50-70% for our micro hydro system).
What is the cost of your micro hydro turbine ?
The cost of micro hydropower system is quite different, so need to request the quotation case by case. Normally our micro hydropower production cost is around USD400-2,000 per kW based on detail turbine selections and materials. And total cost for micro hydro system including local labors around USD4,000-10,000 per KW.
Which kind of turbine is suitable for my site?
Though there are different water turbine types, but maybe only 1-2 type is mostly suitable for your site, which is up to your local site condition and your required output power.
Can the micro hydropower grid tired?
Of course Yes, our micro hydropower system could run stand alone or connect to the national grid. Both options are available.
Are you micro hydro turbine manufacturer ?
Yes DLLD power is the pioneer of Chinese micro hydropower manufacturer to provide the top quality level system to worldwide, with full series solution ranging from 0.1kW-100KW. And also we can design and develop new system based on different site conditions.
How long would i receive my system from China ?
Generally our production lead time for conventional models is around 30-45 days, for some new designed models it may take longer time around 2-3 months. And we can arrange the export and transport by Sea or Air based on your choose.
Greeting from Chairmen
Mr. Xiong Ying is dedicated to research and design all kinds of micro hydro turbine unit since 1991 year, as the pioneer of micro hydropower, he participated in the implementation of Chinese micro hydropower industry standard. And also cooperate with foreign institutions to develop local hydropower projects, such as EDF in France, AZ in Switzerland, E+ CO in America, UNIDO in Africa and so on.
“I have a dream to help the worldwide people from islands or remote areas have the access into electricity under micro hydropower system or solar power system, assist those desiring to utilize available water resources to generate electrical power at a reasonable cost. Greatly pleased to develop global micro hydropower projects with all kinds of worldwide partners together. “

Why micro-Hydropower?
DLLD Micro Hydro Systems Advantages
1. Small size, lightweight, and reasonable integrated design, for the stand-alone system we use rare earth permanent magnet synchronous generator for super-reliable performance and simple structure. For on-grid usage, we can use the asynchronous generator.
2. Equipped with automatic voltage and frequency regulation control function, our ELC controls the electricity for the generator and sends the excess electricity to a dummy load fully. Take an example, if the load loss is 20%, our thyristor will automatically balance this 20% load by itself fully to keep the voltage stabilization.
3. DLLD hydroelectric equipment can be output AC power directly to be used as a power source for lighting, watching TV, and dragging micro agricultural and by-product processing machinery for farmers. Also could be stored in the battery for peak usage.
4. DLLD combines a micro water turbine, generator, voltage, frequency stabilization controller, etc. integrated together, with reliable performance and low maintenance cost, which also increase the lifecycle by 20-30 years.
5. Our micro-hydropower system is an environmentally friendly product, with obvious social and economic benefits.
If you are interested in building a micro hydropower power, please advise your available water source data for further discussions, such as Net Head (m), Design Flow (l/s), Required output Power (kW), Required Voltage(V), Frequency (50Hz or 60Hz), Off-Grid or On-Grid, etc as more details as possible.
