Mõõteseade laserjälgijat Freen Ltd hakkab kasutama suurte keevitatud detailide ja CNC töödeldud detailide mõõtmiseks. Kõige suurem detail on ca 30m lineaarses mõõtmes.

Tuule mõõtesüsteem, mis võimaldab mõõta tuule kiirust erinevatel kõrgustel. Süsteem peab registreeruma tuule kiirust ja edastama andmed formaadis, mis võimaldab edasi Freenil need andmed lihtsal viisil analüüsi teha enda pool. Selle eesmärk on aru saada erinevate kohtade tuule profiili ja paremini analüüsida ka tuule generaatorite võimsust.

In the blade system of Freen turbines, there are PU foam components. We need moulds for production of PU foam components. Since Freen doesn't have competence in this field, we are looking for a supplier that would be able to design, produce and test PU foam moulds.

Winding equipment is needed in production of generators. The application is to do winding of rectangular enamelled copper wire on the lamination core assemblies for 15KW and 55KW Freen Ltd turbines. This equipment should ensure automated and high quality winding process that will result in lower costs of these subassemblies and as a result - lower costs of 15KW and 55KW generators.

Purchase of moulds that are used in thermal forming process. Thermal forming process is used for production of blades components - shells of blades segments.
