GemStart 5-R - your GemStart upgrade solution

COMECA understands the challenges faced by many operators in maintaining equipment beyond the intended design life. Thanks to its know-how of Original Manufacturer, COMECA has therefore developed a Retrofit solution called GemStart5-R, which consists of the replacement of all older versions of GemStart protection relays with modern and updated GemStart5.

You are considering replacing your old version of GemStart? You prefer an alternative solution to upgrading?

COMECA also offers a repair service for all GemStart versions. Contact us for more information.

Retrofitting is a practical, cost effective and least disruptive way to address both planned and unplanned outages, improving equipment operation and reliability for the short and long term.

GemStart 5 is the only product available for new Motor Control Centres and our GemStart5-R retrofit solution for older versions, giving the operator a common product for all legacy GemStart equipped Motor Control Centres.

Gemstart 5 can co-exist on the same network as older versions of Gemstart, thus enabling the end user to perform upgrades to suit plant outages without the need to change out the entire Gemstart network.
