Charge Air Cooler (Standalone) · Heat Exchangers
Donghwa Entec Air Cooler (Charged Air Cooler) — Marine Main Engine Turbocharger Cooling. As a Shell-and-Tube Heat Exchanger, it is normally installed in an engine-room cooling, heating, condensing, feedwater or process circuit according to the listed duty. In that role, its primary purpose is to transfer heat between two fluid streams while keeping the media separated, or to condition feedwater in a heat-transfer vessel. Shell-and-tube units differ from plate exchangers through their tube bundle and shell construction, and special deaerators or air heaters add process functions beyond simple liquid-to-liquid cooling. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Surveyors check air side and water side cleanliness, differential pressure across the cooler, tube leak tests, and condition of the water chamber coating and anodes. Cleaning intervals follow fouling trends and charge air temperature.
Keep gasket and seal sets, spare cooler elements or tube bundles where practical, tube plugs, anodes, and drain parts. Carry cleaning chemicals suitable for the tube material.
