COLD STORAGE CALL SYSTEM
Cold storge call system is an effective tool for safe working in cold storage to communicate with he outside world in emergency situations. In case of emergency, staff can send audible and visual alarm signals to call the outside crew for assistance through the cold storage call system, to ensure he personal safety. Cold storage call system is an important safety equipment in cold storage for large and medium-sized ships, it conforms to lEC60092-203 standard of National electrical Engineering Committee and meets the domestic and foreign classification society standard.
