El-Service is renewing the valve system onboard the pelagic trawler Christian Í Grótinum. The old system was very unstable. It containes 96 motorized valves manufactored by Eltorque. The first stage containes 26 valves and the sounding system. The next stage will contain the rest of the valves and a RSW system manufactored by York. The third stage will contain the rest of the alarm system and other systems. We use our ESAI500 system which is based on the SCADA software IGSS from Schneider-Electric.
