SCF8C-J Quadro jockey ( – K Engines Europe

Controllers per elettropompe Jockey EN 12845 / NFPA 20

I pannelli di controllo SCF8C-J hanno specifiche elevate e sono piccoli strumenti facili da usare e configurabili, utili per azionare automaticamente i gruppi elettrogeni Jockey in qualsiasi ambiente

I pannelli di controllo SCF8C-J avviano e arrestano automaticamente le pompe Jockey a seconda della richiesta del sistema; le proteggono tramite allarmi collegati e generati dal controller, visualizzano i valori e le informazioni più rilevanti, gestire anche la comunicazione dell’operatore e sia gli elementi di contorno che il centro presidiato a distanza.
