Wind Turbine Refurbishing

 

MWPS World Limited works with highly skilled re-manufacturers, refurbisher and machinists to ensure the re-manufactured equipment is properly restored to the original manufacturers specifications and is refurbished according to our high standards.

Refurbished wind turbines offered by MWPS World Ltd. 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 wear parts. The main moving components will be reconditioned to new or better than new standards. The controls, gearbox, hub, generator, 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.
