Drinking water from the sea
MSF Technology — Vacuum Multi-Stage Flash Distillation
La Multi-stage flash desalination (MSF) is an innovative technology for producing very clean drinking water through vacuum distillation. From individual homes to industrial companies — a scalable modular system from 1 to 1,500 m³ of pure water per day.
Isothermal Innovations Inc. represents MSF technology in Panama and Central America.
Use cases
MSF technology is the most widely used method for producing drinking water from seawater — homes, hotels and restaurants, schools, clinics and hospitals in coastal areas, vessels, and industrial projects.
Drinking water
Infant-grade water quality, purified to below 1 ppm (one millionth of dissolved matter). MSF removes not only salt but also mineral and microbial contamination. In some areas contaminated water is responsible for up to 80% of illness — MSF solves this at the root.
Agricultural irrigation
When waste heat powers the equipment, costs are nearly zero — making it viable to use the water for irrigation in areas lacking moisture. Unlike reverse osmosis, MSF does not degrade soil through progressive salinity. It allows agriculture to intensify sustainably.
Fishing vessels
Caught fish must be washed in fresh water before freezing. Waste heat from the boat's engine, with an MSF unit, produces fresh water directly on board — suitable for washing fish, drinking, and general crew use. Works on any type of vessel.
How does it work?
The pressure reduction inside the device causes a marked decrease in water's boiling point. This translates into lower energy consumption and lower cost per unit of water produced. The technology is supplied as a distillation unit with brine recirculation.
Modular system: standard capacity ranges from 1 to 1,500 m³/day; capacity can be increased at will by combining modules. This allows maximum adaptability to the site, especially useful for projects with space or power constraints.
Four key reasons
Alternative energy
Solar, wind, hydrothermal — any renewable source can power the MSF.
Waste heat
Save money by harnessing waste heat from generators, engines, transformer stations, or exhaust lines.
Easy maintenance
Simple operation. Suitable for remote sites with little skilled labor. Optional remote monitoring.
Think Green!
Modern, environmentally friendly technology — no CO₂ emissions, no greenhouse gases.
Flexible power sources
MSF can run on conventional power, renewable energy, or waste heat — reducing operating cost to nearly zero.
Benefits
Extremely low-cost drinking water
By harnessing existing waste-heat sources, MSF produces clean water at practically zero operating cost — viable for drinking, cooking, and irrigation.
21st-century technology
Purifies to <1 ppm. Reverse osmosis barely reaches 300 ppm with new filters. MSF removes salt, minerals, and microbial contamination in a single stage.
No CO₂, environmentally friendly
No greenhouse-gas production. No buildings or complex pretreatment filters needed. No diesel high-pressure pumps — eliminating fuel installations.

About us
We are a team of environmentalists who hope to see the advance of inhospitable deserts turn back into green zones full of wildlife and lush vegetation.
Seas and oceans cover 71% of the Earth's surface. By harnessing wasted heat and energy that contribute to global warming, we produce very cheap, affordable drinking water from the sea.
Our mission
To make access to drinking water possible for everyone who suffers from scarcity. We know the road ahead is long. Even so, we have a vision to make it a reality, and we believe this goal can be achieved.
We work to make quality water available to everyone suffering from scarcity, to enable irrigation in areas being lost to advancing deserts, and to give users of technical equipment and transport the ability to harness the waste heat from their own processes.
