DALIFANT A QUIET, WIDELY CERTIFIED AND RELIABLE WIND TURBINE SOLUTION

The Dalifant is a fully integrated, utility-connected wind energy solution designed specifically for homes, farms, small businesses and community projects. It is an II kW turbine installed on a 19,8 meter wooden tower. The solution offers the following benefits: - High energy production due to oversized blades - larger than for all available 30 kW solutions; - Tried and tested design through multiple installations in Denmark, the UK and the USA; - Silent operation: the quietest turbine in its class across full range of wind speeds; - Reliability and safety: three levels of braking...

Installed Base Validated through a substantial installed base: more than 500 wind turbines installed around the world and more than 1255 years of combined operational history

Due to its exceptionally large rotor diameter the energy capture of the Dalifant is considerable even at low wind speeds, thus making wind energy generation feasible at locations where the average wind speed is Large swept area ensures very effective use of wind resource resulting in greater amount of energy generated: the oversized rotor captures up to 80% more wind energy than other turbines with the same rated power

Data Monitoring and System Protection » Data input and management - Integrated microprocessor with multiple sensor input - Online monitoring option accessible via computer * System protection I. Base level: Passive stall of blades limits power output 2. Second level: Control system activates mechanical brake if: - Wind speed exceeds 25 m/s - Abnormal vibration occurs - Grid is disconnected or generator overheats 3. Third level: Centrifugally activated aerodynamic brakes built into rotor tips function as a final safety measure. Additionally, there is a manual override button, which activates...

Wooden Towers - a Unique Sellin Use of wood results in a number of practical, aesthetic and environmental benefits that steel towers (today's industry standard) cannot provide

Practical Benefits of the Dalifant XX Wooden Tower

Foundation brought to a new leve The novel screw foundation revolutionizes the FAST: installed in hours instead of weeks for a standard concrete foundation. GREEN: for the Dali XII, it causes 7 times less CO2 emission than a concrete foundation, allows for significant water saving (more than 380 litres!) and requires no soil movement. UNIQUE: The screw foundation is only possible because of our multi-leg designs and is not applicable to a steel tubular tower. It is the foundation of choice for both tower designs:

Smaller Concrete However, if it is necessary to use a concrete foundation, our tower solutions require considerably less (2 and more times less) concrete than a steel tubular tower. turbine requires: > 7 m3 for a steel tubular tower installation Same proportion is valid for the Dalifant XX

Timber used for InnoVentum's wooden towers is proven to reduce noise of small wind turbine installations. Since the velocity of sound waves in wood is low, wood is one of the best sound insulators. While a conventional stand-alone steel tower amplifies the noise through a hollow tube construction, the Dalifant multi-leg wooden tower absorbs this vibration, making the operation of the turbine much more silent. Wood under the microscope:

Our towers are designed to sustains wind gusts of up to 60 m/s and their expected lifetime is The in-house maximum load test at the Lund Technical University with 20+ years of experience Installation at one of the windiest spots on the windiest island in Sweden - Oland - withstood several storms over

Environmental Benefits of the Dalifant XX Wooden Tower

Wood has the unique ability to capture and store C02 while reducing carbon • remove CO and store it - increasing "carbon sinks" ^P^^ Wood has the unique ability to do both. Each cubic metre of wood saves a total of 2 tons of C02. Every cubic metre of wood used as a substitute for other building materials reduces C02 emissions by an average of I, I ton C02. If this is added to the 0,9 ton of C02 stored in wood, we get a total There are 2 ways to reduce C02 in the atmosphere: reduce emissions or "carbon sources Source:TockJe climate change. USE WOOD
