Since its founding in 1949, Sasakura has been engaged in research and development as a leading manufacturer of fresh water generators, providing a wide range of products to the world and meeting the needs of the times quickly and accurately.
Sasakura’s fresh water generators have been installed on ships built in Japan as well as internationally, earning the firm trust of our clients through world-class technology and quality.
Using hot water
The”EX-Series”is an epoch-making plate-type Fresh Water Generator. Since the plate-type heat exchanger part is uncovered, the Fresh Water Generator takes up less installation space, and maintenance/inspection work is easier and less time-consuming as a result. This Fresh Water Generator uses the waste heat from diesel engine jacket cooling water to heat seawater and evaporation takes under vacuum to produce fresh water. Model capacity is available from 20 to 45 t/d of fresh water. A steam injector or a steam booster unit can be supplied to produce fresh water by steam as well.
This is the most popular distiller for diesel-driven ships, and more than 10,000 sets have been delivered all over the world.
5~100 tons per day type of capacity can be provided.
A steam injector or a steam booster unit as an option can be supplied to produce fresh water by steam as well.
Series WX was developed under two factors: improvement of new engines downsizing and high efficiency, resulting less heat amount provided.
Expecting types of fresh water generator which can produce more fresh water to meet the demands of environmental equipment for new regulations.
Compared with series X, new series WX can produce more FW with half of heat consumption.
Capacity: 20-40 tons per day are available models. Steam Injectors are available as option, for supplied Steam.
Using hot water/steam
The Double-Effect plant is a compact, highly heat efficient seawater distilling plant with two chambers of 1st and 2nd effect in a single shell. The Triple-Effect plant contains three chambers of 1st, 2nd and 3rd effect, and is an even more highly efficient plant.
As a heat source, either the waste heat from a diesel engine jacket cooling water or steam can be used. 40~200 tons per day type of capacity can be provided.
Steam turbine engine ships require extremely pure fresh water for high pressure boiler feed water, as well as a high level of reliability.
These distilling plants use low pressure steam from the turbine bleed to heat seawater. A part of seawater evaporates into vapor which is condensed to fresh water in the distiller.
This plant uses low-pressure steam as a heat source.
The multi-stage flash-type system has several evaporating chambers, and can efficiently generate mass quantities of fresh water without using much heat. 100~1000 tons per day type of capacity can be provided, and is used on ships that consume mass quantities of fresh water, such as passenger and fish factory vessels.
Using electricity
Designed for use in harsh marine environments, this energy-saving, low-maintenance vacuum vapor compression fresh water generator provides a stable supply of fresh water essential for food preparation, hydration, and daily life. Operation requiring only electricity eliminates the need for steam, hot water, or other heat sources.
