PURIFIER MODULE UNIT, which is composed of MAIN ENGINE F.O. SUPPLY UNIT, GENERATOR F.O. SUPPLY UNIT and BOILER F.O. SUPPLY UNIT, is so large that it even forms its own room in a ship. In addition, the engine of a ship is also so large that it requires large quantity of fuel.
Therefore, relatively inexpensive BUNKER OIL is mainly used for ships and PURIFIER UNIT is installed to purify BUNKER OIL.
A great number of valves and devices are equipped as a module unit so as to transfer purified oil from PURIFIER to each STORAGE OIL TANK in the engine room, and to easily utilize and maintain those valves and devices.
