Your tailor-made turnkey electrical network!

"We have been equipped with ICE relays since our creation with full confidence in the quality of ICE protections. So when we wanted to expand our network, we naturally turned to ICE. Having a dedicated contact for our project made the creation of our new network easier and successful! " YARA – Electrical Projects Manager

NP900 Series: save time in the management of your electrical network!

"We have been equipped with 7000 series CEE static relays since our creation in the 1960s. Maintenance is a recurring problem. We have very little time available to devote to the management of our HV network protection equipment. We have several static relays per cell and they do not allow fault analysis. The replacement of these relays by ICE saves us a precious time!" SIR – Maintenance Manager

NPRG870 relays: the solution to simplify and improve the management of your hydraulic systems

"We want to simplify our electrical cabinets so that we can easily use the relays to consult and analyse the events. The synchro-coupler currently used does not give us satisfaction. The couplings are slow and in some cases the regulator cannot perform the coupling.
Since ICE's intervention, several of our plants have been equipped with NPRG870 relays, and deployments continue."
