[Company Introduction]

Since our founding in February 1980, as the manufacturer of heat-exchanger for the marine, petro-chemical and power generation industry, DongHwa Entec has been focused on research & development, product performance improvement as well as new product development while establishing the most competitive facilities and production processes.

[Product Description]

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, DongHwa Entec’s Seawater Heater may be used.

Sea water direct heating - Combined open/closed loop with seawater and steam heating
