Here you will find the recommended checklist for routine capacitor bank maintenance.
Your engineering team or facility management should follow the steps.
It will increase the lifespan of the capacitor bank, increase its efficiency and prevent accidents like sparks, fire etc. In other words it will protect your investment.
We also offer capacitor bank maintenance.
For any clarification, our engineering team is more than happy to help you and offer our services for all facilities – industrial, business centres, hotels, malls and residential buildings.
