Wind Turbine Refurbishing

Refurbished Wind Turbines

MWPS World works with highly skilled re-manufacturers, refurbishers, and machinists to ensure the refurbished wind turbines or remanufactured equipment is properly restored to the original manufacturer’s specifications and is refurbished according to our high standards. Refurbished wind turbines offered by MWPS World are completely disassembled and thoroughly inspected and cleaned. Our highly experienced wind turbine refurbishment affiliates evaluate the condition of the reconditioned wind turbine and replace all worn parts. The main moving components will be reconditioned to new or better than new standards. The controls, gearbox, hub, generator, and hydraulic system are all thoroughly reconditioned and are either restored or replaced. All refurbished wind turbines come with a full technical report of the reconditioning work undertaken and come with a standard 1-year warranty on replaced and refurbished parts and workmanship. Extended Warranty up to 5 years optional.

Refurbished Wind Turbines

Completed refurbished wind turbines are restored to the original manufacturer’s specifications and offer a minimum warranty of 1 year. Extended warranties may be purchased upon request.

Depending on the turbine type and size, a typical reconditioning process takes approximately 3 months and up to 1 year for very large size turbines.
