General information
Polenko was a Dutch fabricator of windturbines specialising in both big and smaller models. Polenko produced high quality turbines serving a wide varienty of purposes. We offer a wide variety of components for their WPS18 model. These components can be sold seperately, or they can be used to set up complete windmill installations as well.
- Strong solid construction
- Stable operational characteristics
- Long life expectancy
- Extensive multiple security measures
- low cost of maintenance
The WPS 18 has been an in demand turbine in it’s days. In many cases, it was sold to parties consuming vast amounts of energy like companies with heavy machinery or cooling units, structures that required a lot of light, swimming baths, residential areas, etc. The turbines have also sucesfully functiones in a wind-park setup. The turbine is very solid, and equipped with all nessecary features. The standard of this turbine has been made suitable for connection to local electricity networks in model SM (synchroneous generator and mutator. Yearly revenue with an average windspeed of 6 to 8 m/s was estimated at 140.000 to 250.000 kWh

History of Production
Polenko was a fabricator of windturbines specialising in both big and smaller models. These were high quality turbines serving a wide varienty of purposes. Polenko was located in Rhenen, with Pol (Pol en ko) as owner. Polenko supplied small wind turbines with steel blades in the range 30 kW.Nedwind was a Dutch wind turbine manufacturer. The company went on to become wind turbine manufacturer Newinco. This later went on to become Nedwind. Nedwind was one of the three major Dutch wind tube manufacturers.
Nedwind Wind farms were built, among others, at the Volkerak locks (NW40), Eemmeerdijk (NW50), Hartel Canal (NW40), Enkhuizen (NW25), Neeltje Jans (NW25) and in the water near Medemblik (NW40). Wind turbine parks have also been built abroad. For example in Curaçao (NW25) and in Palm Springs in California (NW40). In 1998 Nedwind was taken over by the Danish NEG Micon. Part of Nedwind was later divested and continued under the name Mainwind.
