Company Profile:
Since Donghwa Entec was established in 1980, the company has progressed in a professional manufacture of heat exchangers for marine, powe plant, foods factories, land industial field and charge air cooler for diesel engine and also was appoinited as only one special manufacture of marine equipments in heat exchangers by goverment in october,1982.
Based on the skilled manufacturing know-how and technology backed by marine and land field experience over twenty years and it's our sincere hope that our pursuit of quality and cost competitiveness will continue to contribute to our customer's properity, thus furhtering economic development and individual well-being throughout the world.
Profiltitel

Auxiliary systems for propulsion Cooling water systems* Fuel oil systems* Ship operation equipment Cooling systems* Environmental protection technology and products* Heating systems* Tank cleaning systems*

What we offer:
ESS(Energy Saving System)

-ESS monitors the temperature of Seawater, low temperature freshwater and the positions of 3-way valve and controls the speed of central cooling seawater pump to optimize the capacity of seawater pump. So, it can save the power consumption for operation cnetral cooling water pump by appling inverter for frequency control.

Advantage of ESS

Reduction - Starting current, Extermination of High-Frequency waves
Control - Variable Frequency / Speed control , Linear control of pump
High E-Saving - Up to 40%
Green - Reduction of Greenhouse Gas Emission

MGO Cooling Unit

For the lowest viscosity distillates, MGO Cooling Unit to be installed to cool down min. 2cst of MGO for fuel contents regulations by EU and CARB(California Air Resources Board )

Direct Type MGO Cooling Unit

Donghwa system was designed to assure to stable and continuous operation of compessor with min.25% load without frequent stop adopting additional heat exchanger(load cooler).
Also, can strictly control and satisfy inlet temp. of MGO/MDO to the engine linearly by PLC&3-way valve control, was designed absolutely to protect the mixing problem between refrigerant and MGO/MDO adopting very special heat exchanger with dual tube.

In-Direct Type MGO Cooling Unit

Chiller unit + Water pump unit + oil cooler unit.

What we are looking for:
We are interested in shipyards,shipowners,maritime companies who needs to Auxiliary systems for propulsion.

Keywords:
  • Auxiliary systems for propulsion (generators, etc.)
  • Systems for air-conditioning, ventilation, cooling, heating
