Product catalog summary

Overview
Korea is a leader in international shipbuilding, known for advanced technologies and high productivity. Donghwa Entec is a key player in this industry, specializing in heat exchangers and energy-saving systems.

Company Information
Donghwa Entec has multiple offices and facilities in Korea and China, with its head office located in Busan, Korea. The company is committed to expanding its global market share in heat exchangers and energy-saving systems.

Product Specifications
The document provides detailed specifications for the Energy Saving System (ESS) models, including power requirements, pump motor capacity, dimensions, and weight. All models operate at 440V, 3-phase, 60Hz, with varying motor capacities from 15KW to 250KW.

Energy Saving System (ESS)
The ESS is designed to optimize the operation of central cooling systems on ships, reducing energy consumption and greenhouse gas emissions. It uses inverters for frequency control, allowing for significant energy savings and compliance with the Energy Efficiency Design Index (EEDI) regulations.

Operating Principle
The ESS monitors sea water and fresh water temperatures, as well as the position of a 3-way valve, to control the speed of the central cooling sea water pump. This optimization reduces energy consumption and enhances the efficiency of auxiliary machinery.

System Components
The ESS includes a control panel, inverters, and various sensors such as pressure and temperature transmitters. It offers different operation modes, including inverter and bypass modes, to adapt to varying conditions.

Benefits
The ESS provides up to 40% energy savings, reduces CO2 emissions, and offers automatic anti-fouling flushing. It ensures system stability by setting minimum flow rates and allows for continuous operation with variable pump speed control.

MAIN ENGINE CENT. COOLER | Energy Saving System for Central Cooling Sea Water Pump | Current Central Cooling System Central Cooling System with ESS Energy Saving System | Introduction | Heat occurred during ship operating is cooled down by sea water and the temp. of sea water itself is a key factor that influences other aux. machineries. In case the actual sea water temp. is lower than design one, thermal capacity of aux. equipments is enhanced and consequently, the flow rate of sea water can be reduced. However, almost all ships are operating under reqular electirc consumption for sea water...
