　　Spray & tray type are usually used for onshore plant and spray & scrubber type are mainly used for offshore vessel. DongHwa Entec has been testing and developing main parts of deaerator like spray, tray and scrubber, and steadily researching for upgrading those performance so far.
　　Also, we are truly trying to meet customer's expectation with batch processing system ranging from performance design, hardness design, procurement to manufacturing and delivery.
