• I nter Cooler is installed at the end of compressor to chill the compressed gas. This heat-exchanger chills the air or gas discharged from compressor in industrial ASU plant or oil & gas plant, and removes moisture accordingly. Consequently, the efficiency of compressor can be improved and energy can be saved. These air or gas are compressed by cooler at the last stage, and then to be cooled to its required temperature after passing through the Cooler. • After Cooler is installed at the end of compressor to chill the compressed gas. This heat-exchanger chills the air or gas discharged from compressor in industrial ASU plant or oil & gas plant, and removes moisture accordingly. The allowable pressure drop is very limited, and demister is installed inside to remove moistures. • Also, for increasing the efficiency of heat-exchanger, the Plate Fin type or High Fin type is applied to where air or gas is being taken or discharged.

• Gland Condenser is used to collect condensate and calories of steam that used for sealing steam turbine, and it also creates a state of vacuum to help discharge of steam. The thermal energy is transformed to the kinetic energy as steam of high pressure-high temperature rotates steam turbine. Thus, Seal Steam System is necessary to prevent steam leakage from steam turbine and air infiltration into steam turbine. Gland Condenser collects condensate and steam calories as well as creation of vacuum state inside of Seal Steam System, and it also steam discharge. • Surface Condenser generates vacuum backpressure to ensure output of turbine, and also condenses a wastesteam while located at the end of steam turbine which is generally used in industries such as power generating in power plant, compressing in chemical plant as well as propelling of LNG tanker. Depends on the location of Surface Condenser against turbine, it is classified into Topentry type and Side-entry type. The circular type surface condenser is used for small size and medium size while square type surface condenser is used for large size such as power plant.

• Oil Heater is used to heat a fuel oil and lubricant oil for ships by using the steam generated from boiler. There are several type of oil heaters in the market: M/E & G/E F.O. Heater breaks the viscosity of fuel oil, while increase inflammable point; H.F.O. Purifier Heater breaks the viscosity of heavy fuel oil, and also increases oil temperature up to the degree which helps purification process. ; and L.O. Purifier Heater increases oil temperature up to the degree which helps purification of lubricant oil used in engine. • Lube Oil Cooler is used to chill lubricant oil that used for lubrication process of various rotating equipment such as generator and compressor in plant, by using cooling water. Also, 3-way valve is adopted for timely replacement of Working Cooler and Stand-by Cooler. Generally, it is manufactured in Shell & Tube type, but Plate-type is also available.

• LNG that is being supplied from RV/FSRU(combination of LNG Tanker, Re-gasification facility and Gas unloading facility) by HP LNG Pump, is vaporized by HP Vaporizer. • The seawater is utilized as a source of heat that vaporizes LNG, and also if the seawater temperature falls down, it will be heated by with Seawater Heating System. In such case, DongHwaEntec’s Seawater Heater may be used.
