Retrofitting your turbine control system pays off

- SysStabV Approved.


Replacement of old obsolete turbine controller systems has been largely ignored, even though retrofitting of aging Nordex, Micon or Wind World turbine, many of which are surpassing their designed lifetime, has long been an area of interest for service and maintenance companies and for the wind turbine owners.

So far, most focus has been put on replacing critical mechanical spare parts in wind turbines - while obsolete control systems have stayed largely untouched. With around 20% of downtime in aging turbines caused by control system errors, a new, modern control system makes surprisingly good business sense.  

Plug-and-play controller for troubleshooting

Spica Technology delivers the only truly competitive alternative to time-consuming control system repairs and price-sensitive second hand controller purchases on the market today. The Spica Retrofit Turbine Controller, and the easy access to spare parts that follows, allows service providers and owners to move focus from the dwindling second hand controller pile to that of investment optimisation.

With more than 20 years of experience in the wind power industry, we have developed a unique line of retrofit control systems for a range of wind turbine types currently in operation. Our retrofit control system is an affordable, plug-and-play system that allows you to professionally manage your investment and trouble-solve, as you would a new, modern turbine.


Crucial data for a range of turbine types

The Spica Retrofit Controller is based on advanced technology, comparable to what you find in modern wind turbines. We replace the old control system in your Nordex, Micon or Wind World turbine with an up-to-date system that provides you with full, remote access to previously unavailable, valuable data. This extensive data collection makes it possible to monitor the wind turbine closely and carry out predictive maintenance that helps prevent costly breakdowns.

The Spica Retrofit Controller is designed to fit most aging stall regulated turbine types, such as Nordex, Wind World, Nordtank, Micon and NEG Micon turbines. The Spica Retrofit Controller is compatible with most monitoring systems and fully compliant with the environment in your turbine. Our retrofit controllers are certified by the Danish Authorities for installation and operation in turbines.

At Spica Technology, we know and respect the costs connected to downtime. Therefore, we have developed a product aimed at reducing downtime from the moment your order is placed. Besides building a controller that physically fits into the turbine controller panel and current wiring - a genuine plug-and-play solution - we provide you with an unprecedented three year exchange guarantee, in case of a controller breakdown or serious malfunction.

Spica Retrofit Controller FAQ

Q:What does the 3 year exchange guarantee cover?

A: Read answer >>

Spica Technology offers a full 3-year exchange guarantee on all Spica Retrofit Controllers purchased and installed from 2014 and on-wards.

The exchange guarantee enters into force once the Spica Retrofit Controller has been correctly installed into your turbine and undergone necessary testing. The exchange guarantee covers a complete breakdown of the controller or a substantial amount of downtime caused by recurring controller errors.  Controller errors that may be eliminated, rectified or corrected through remote access are not included.

To limit downtime as much as possible, a controller exchange is to be carried out as quickly as possible. A controller exchange means the installation of a similar controller in the affected turbine either by Spica Technology or an approved, local service provider.

Please note that incorrect controller installation performed by entities not approved by Spica Technology or a misuse of the controller itself, may affect the validity of your exchange guarantee.
