Fuel Oil Heater · Fuel Oil Treatment
Donghwa Entec Oil Heater (M/E & G/E Fuel Oil Type) — Marine Engine Fuel Oil Viscosity Control. 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 heater cleanliness, pressure and temperature control function, tube leak tests, and insulation and safety devices. On steam heaters, steam traps and condensate return should be tested, and on electric versions, element and thermostat protection.
Keep gasket sets, temperature sensors, control valve or solenoid parts, steam trap spares, and spare tubes or heating elements. Carry cleaning agents for fuel side deposits.
