Micro-Hydroelectric Power Plants ENERGY AND SAVING FROM WAER
Ecowatt Hydro micro-hydroelectric power plants Uses Water is the ideal renewable power source, used by man since the beginning of time. Ecowatt Hydro Micro-Hydroelectric Power Plants, the results of over fifty years of experience in the field, transform the kinetic energy of the water into precious electricity in a clean way and in full respect for the environment. S series plants are the ideal solution for those places where electrical energy is not available from the domestic power grid while A series plants are suitable for producing energy that may be then transferred to the power grid. hey solve the problem of energy supply in many situations, for example in isolated houses, alpine refuges and pastures, missions and small villages. hey also ensure the operation of electric and electronic equipment for remote signalling, remote control and water purification. Besides the use on streams, these plants may be integrated in aqueducs, having natural waterfall, in order to recover the energy which often has to be dissipated through special and expensive equipment and then transform an expensive service in a source of profit. Ecowatt Hydro Micro-Hydroelectric Power Plants provide a considerable contribution to ecology, since they help to avoid the burning of vast quantities of fossil fuel and hydrocarbons, which are held to be widely responsible for air pollution and the greenhouse effect. urbine-generator Group Electric Distribution Board Resistive and Constant Load Electronic Regulating System Electric Energy hermal Energy Other Users Users Air Dissipation Water dissipation S series: Stand-alone Plant urbine-generator Group Users Power Grid Electric Distribution Board A series: Parallel-operated Plant
How it operates S Series ELECRIC CONROL BOARD WAER INAKE LOADING AND FILERING ANK PENSOCK DRAINAGE BLOCK AND CABIN FOR URBINE-GENERAOR GROUP GENERAOR URBINE- GENERAOR GROUP A Series ELECRIC CONROL BOARD USERS Ecowatt Hydro Micro-Hydroelectric Power Plants are designed to ensure simple and effective operation in order to reduce the corrective steps during installation, start-up and routine maintenance to a minimum. As for A series, the plant operates automatically, ensuring the switching and the release of the turbine-generator group depending on the mains availability. he different automation levels depends on water conditions and user s needs. As for S series, the plant operates with a constant power supply. he turbine-generator group constantly transforms hydraulic energy into electric power, regardless of the requirements of the electric users. An electronic regulating system continuously monitors and controls the connected load and deviates the energy in excess to the dissipating systems. his energy can be recovered as heat, either for direct heating of the premises, or for the production of hot water. In this way a system of co-generation, i.e. the production of both electrical and heat energy, is obtained. A manually operated secondary regulation makes it possible to modify the water flow to adapt the turbine to seasonal variations. Ecowatt Hydro Micro-Hydroelectric Power Plants are highly reliable industrial products. hey have been designed for easy installation even in difficult areas. o obtain a good installation some simple, but necessary building work is required. IREM provide the necessary technical papers to support the design and then the installation and use manual for managing the plant. he installation, connection, start-up and maintenance of the Ecowatt Hydro Micro-Hydroelectric Power Plants do not require the presence of specialised technicians. he system, which requires no specific setting, can be easily started up by an electrician and a plumber with the help of the relevant technical documentation. A series only requires the presence of IREM technicians. ELECRONIC REGULAORS WIH AIR OR WAER DISSIPAION POWER GRID USERS Stand-alone plant Parallel-operated plant

Banki or Cross-flow urbines B series hese are suitable for heads from 5 m to 60 m and effective flow rates ranging from 10 l/s to 1,000 l/s. hey offer an excellent solution that reconciles quality, performance and price. he runner and mechanical parts are made of stainless steel. he transmission between runner and generator is entrusted to a cogged belt which ensures the necessary flexibility of the system and optimizes the transmission itself. he flow rate is controlled by a special floodgate which allows variations from 0 to 100%. he operation may be either manual or automatic through electric servo motor. ERAED ELECRIC POWER he data concerning head and available water flow are fundamental for calculating the power output of an Ecowatt Hydro Micro-Hydroelectric Power Plant. By intersecting the X co-ordinate, which shows the head in metres, with the Y co-ordinate, which shows the flow in litres per second, the resulting point will be found between different diagonal sections indicating the electrical power generated, expressed in. he coloured areas highlight the possible operating points of the various standard models available. 300 S4 4 B BA S3 3 B BA 0 400 500 600 800 1000 1200
