The closed cooling water flows toward the shell of the heat exchanger and it is cooled by seawater or service water that flows toward the tube of the heat exchanger.

ENERGYEN has superior technology and competitiveness for basic and detailed design of Closed Cooling Water Heat Exchanger which are installed in thermoelectric,nuclear power plant etc. of domestic or overseas. Also,ENERGYEN carries out the vibration,stress analysis and fatigue analysis to provide customer with improved quality and confidence.

ENERGYEN can carry out the welding between tube and tubesheet with stainless,titanium,copper-nickel with latest equipment such as orbital welding machine. Especially,we can apply rubber lining,ceramic coating and glass flake coating on channel inside to prevent corrosion from sea water.

ENERGYEN has various experience on major code and standard such as ASME,TEMA and JIS and also has experience on local regulation around world such as PED,DOSH,METI and CSA.
