Pitch control retrofit

DEIF delivers a complete pitch retrofit solution for wind turbines running with outdated pitch technology

Maximising reliability of the entire pitch system along with turbine availability, DEIF’s pitch retrofit solutions are customised for wind turbines from 1.5 to 2.5 MW and with electrical pitch systems. You can choose one of the following solutions or both depending on your turbine specifications.

Retrofit solution for easy pitch drive replacement

For easy replacement of the pitch drive, DEIF’s pitch drive retrofit kit can be installed without altering the original system design. It constitutes a good alternative to old wind turbines fitted with for instance L&B pitch controllers. The retrofit kit is flexible and is built to fit the new pitch drive into existing plugs and connections to ensure easy installation without affecting the pitch system. With its redundant safety chain, the IMD improves the overall safety of the turbine. DEIF offers a 5-year warranty on the new retrofitted drive, which includes patented battery storage monitoring as one of the new features. With this solution, you will lower your service cost and the overall Cost of Energy (CoE).

• Pitch drive, IMD 100
• Depending on turbine type (one for each turbine) DEIF’s Pitch Motion Controller, the PMC, and the robust turbine controller, AWC 500.
