Coemi-Skywing 20kw Wind Turbine
The Coemi-Skywing 20kW Wind Turbine is a worthy candidate for use at large energy users, Public bodies, industrial units, large farms and leisure sites.
Its massive 3-blade rotor has a 10 metre diameter using the latest in GFRP blade design technology with a fixed speed rotation of 65 revolutions per minuet generating a maximum of 22kW.
Coemi-Skywing turbines use a unique hydraulic ram system to raise and lower the free-standing 18-meter galvanised tower and therefore do not require a crane for erection or servicing.
Coemi wind turbines come with a five-year warranty (first year labour-free) and are the most technologically advanced on the market. Find out why Coemi wind turbines are the only choice for your business.
Efficiency
Direct grid connection means the Coemi-Skywing wind turbine does not require rectification, dump or inverter, making it up to 20% more efficient.
Safety
Powerful hydraulically operated Twin disc brakes and an induction yaw motor ensure the rotor is stopped and turned out of the wind in a mains failure or very high wind protection against damage ensuring the longevity of blades and components.
Technological
The system is controlled by a Mitsubishi controller which monitors the wind speed, direction, load, mains voltage, mains cycle Hz and rotation speed.
GPRS is used to enable engineers to monitor and update the turbine remotely through the internet.
Features:
- Mitsubishi PLC controller
- Fixed speed 50Hz Electro magnet generator
- Super quiet gearbox
- GPRS Internet monitoring means your turbine can be monitored remotely and technical updates and adjustments can be carried out without a site visit.
- Powerful Induction yawl motor is used to turn the head in and out of the wind ensuring maximum reliability and life.
- Twin hydraulic disc brakes for emergency stop and hand brake.
- Fully galvanised free-standing tower, Hydraulically raised and lowered (no crane required).
- CE and MCS approved
- 5 year manufacturers parts warranty
Typical installation costs including base and planning, however installation costs can vary. Cable lengths can also vary and are not included.
