COOLING
CHILLED WATER UNIT FOR MGO
Due to the regulation on Sulphur emission caused by heavy marine fuel oil consumption, IMO MARPOL Annex VI 2008, EU Directive 2005/33/EC, and California Air Resources Board(CARB) are now requiring the shipping industry to use fuel oils with lower percentage of Sulphur.
In response to this, a new type of low Sulphur fuel(Marine Gas Oil) has been developed of which viscosity is very low, so the performance of fuel pump are deteriorated.
HI AIR KOREA(HAK) takes the design challenge to keep the viscosity and lubricity of low Sulphur MGO at safety limits to avoid fuel pump break down.
HAK CHILLED WATER UNIT FOR MGO’s efficient fuel temperature control via PLC system ensures proper level of viscosity even at lower loads. Means of cooling are direct and in-direct cooling type.
HAK CHILLED WATER UNIT FOR MGO system guarantees great service even when switching to low Sulphur fuel!
