Small reliable output for remote placesThe Forgen wind driven generator embodies long established high efficiency generator principles, combined with turbine airflow expertise. Low inertia of the carefully balanced all-aluminium rotor assembly enables the maximum advantage to be taken of average weather conditions. The two machines in the range, the Forgen 500 and the Forgen 1000, can produce in an average 15 knot wind speed either 12 or 24 amphrs in a 24 hour period (depending on battery condition). The design of the machines is such that in extreme wind conditions the turbine is self regulating. The electronic circuitry is also internally protected against overload, neither machine requires an external regulator to be fitted.
The turbine drive of the permanent magnet generator is widely acknowledged as the most efficient design, and when mounted vertically it takes advantage of wind from any direction. All electrical components are encapsulated and the unit is virtually maintenance free, especially as there are no slip rings. The outlet supply cable to the battery cannot become entangled. As there are no separate blades the unit is vibration free and silent in operation. The Forgen 500 is designed as a trickle charger and may be permanently connected to the battery. The Forgen 1000 gives a higher charge and has been designed for larger multiple battery installations usually associated with boats over 10 m in length. The use of a Forgen ensures easy start up after overnight or week-long mooring of sailing craft. Parked caravans, electric fence units, sea bouys or other remotely situated electronic equipment are also typical uses for the Forgen. It is well known that batteries have a much longer working life when maintained in a fully charged condition, and even a small charge current will help prevent battery deterioration. The generator circuit is designed so that the battery cannot be overcharged, and is self adjusting for 12 or 24 volt batteries. High winds present no problems for the Forgen Generators. The aerofoil design of the rotors mean that surplus wind is 'dumped'. In wind tunnel tests using smoke, once maximum revolutions have been reached, excess air can be seen 'pluming' out of the top of the units. The more the wind increases, the bigger the plume! |
FORGEN 500NTThe FORGEN 500NT vertical axis wind driven generator embodies long established, high efficiency generator principles, combined with turbine airflow expertise. Low inertia of the carefully balanced all aluminum rotor assembly enables the maximum advantages to be taken of average weather conditions. The Forgen 500 is the smallest vertical axis machine in the range and measures just 200mm diameter in plan dimensions and just over 300mm tall. This small entry level unit is designed for single battery installations typically up to 150Ah of battery. There are two models offered in the range, the normal temperature model (NT) and the low temperature model (LT). The Forgen 500 NT is suitable for temperatures down to -20 degrees Celsius, where as the low temperature models are designed to continue operating in temperatures down to -50 degrees Celsius. Uniquely, during high speed wind tunnel tests the Forgen 500 model was still spinning and delivering output in 100mph winds, which is often seen as a challenge for many horizontal axis machines.

FORGEN 1000 SERIESThe Forgen 1000 is the larger scale vertical axis machine in the range and measures 300mm diameter in plan dimensions and just over 465mm tall. This unit is designed for multiple battery bank installations typically up to 450 Ah. There are also two models offered in the 1000 series range, the normal temperature model (NT) and the low temperature model (LT). The Forgen 500 NT is suitable for temperatures down to -20 degrees Celsius, where as the low temperature models are designed to continue operating in temperatures down to -50 degrees Celsius. Like the Forgen 500 model, during high speed wind tunnel tests the Forgen 1000 model was still spinning and delivering output in 100mph winds, which is often seen as a challenge for many horizontal axis machines. Please also refer to the mounting options available to select the right choice for your application.
