I.S.S. Industrial & Ship Services BV had build a switch panel for a dredger ship. This switch panel had a conventional operating system, using manual switches to control the circulation pumps and the booster pumps and analogue hour counters for the burner and the pumps. In addition to this, the front panel has I.S.S. electric controllers to show the temperature of the oil fired heater, the economisers and the dumbcooler, to show the dewpoint of the override bunker tanks and to show the status of the minimum flow of the boiler system. On the inside, Siemens LAL 2.25 oil burner controller was used. The system is placed in a powder coated cabinet, made by Rital.
