Marine freshwater distillation system
freshwater distiller
energy-efficient freshwater production for any vessel.
The Freshwater Distiller is a vacuum evaporation system designed to convert seawater into high-quality distilled water for offshore platforms and marine vessels. Utilising waste heat sources, it provides an energy-efficient and reliable supply of technical or potable water while minimising maintenance requirements.
Process
Vacuum evaporation
Construction
Cupronickel, naval bronze, duplex & super duplex steel
Water quality
Salinity below 4 ppm

distilled / technical water
energy-efficient distillation
The Freshwater Distiller uses vacuum evaporation to convert seawater into low-salinity distilled water, recovering waste heat from hot water, steam or thermal oil sources already available onboard to keep energy consumption down.
Process
Vacuum evaporation
Water quality
Below 4 ppm salinity
Distilled output can be mineralised and disinfected with an optional treatment system to make it suitable for human consumption.
Main features
- Produces distilled water using energy-efficient vacuum evaporation
- Operates using hot water, steam, or thermal oil as heat sources
- Manufactured from cupronickel, naval bronze, duplex, and super duplex steels for long service life
- Distilled water can be mineralised and disinfected for safe human consumption
Main advantages
- Recovers residual heat to reduce overall energy consumption
- Provides a continuous supply of low-salinity distilled water
- Robust marine-grade materials minimise servicing requirements
- Designed specifically for demanding offshore and marine environments
from seawater to freshwater
Waste heat already present onboard — hot water, steam or thermal oil — drives the vacuum evaporation process, turning seawater into a continuous supply of low-salinity distilled water.
Water quality
< 4 ppm
Heat source
Hot water / Steam / Oil
An optional mineraliser and disinfection system can convert distilled output into potable water.
