Katadyn Group

Desalination and safe drinking-water treatment.

The Katadyn Group is a water-treatment specialist whose reverse-osmosis desalinators and drinking-water systems make seawater and questionable fresh sources safe to drink. Its products are built for marine, expedition and emergency settings, where reliable potable water matters as much as any other system aboard. PowerSol distributes Katadyn Group across Southern Africa.

Katadyn is known for two closely related disciplines: turning seawater into fresh water through reverse osmosis, and rendering fresh water of uncertain quality safe to drink. The desalinator range applies pressure across a semi-permeable membrane to separate salt and contaminants from seawater, producing potable water onboard rather than relying on tanked supply or shore connections. The drinking-water treatment range addresses inland and expedition use, where the source exists but its safety does not.

For a boatbuilder or marine installer, an onboard desalinator changes the water equation entirely. It reduces dependence on tank capacity and marina fill-ups, extends range and time at anchor, and frees displacement that would otherwise go to stored fresh water. For overland and expedition users, portable treatment systems make remote travel viable where a clean tap is never guaranteed. In both cases the value is the same: a dependable supply of drinking water produced from what is actually available.

PowerSol supplies the Katadyn Group range for leisure-marine, commercial-marine and mobile-overland customers, supporting installers who specify water-making and treatment as part of a wider power and systems build. Because desalination and treatment sit alongside the energy and electrical systems PowerSol already distributes, they can be planned together, from the power budget a desalinator draws to where the unit and its plumbing are sited.

Why specify Katadyn Group

  • Specialist focus on water alone, spanning both reverse-osmosis desalination and drinking-water treatment rather than treating water as a sideline category
  • Coverage across marine, expedition and emergency use, so a single brand can serve a yacht refit, a commercial vessel and an overland vehicle
  • Onboard desalination reduces reliance on tank capacity and shore supply, extending range and time at anchor
  • Distributed and supported regionally by PowerSol for Southern-African marine and overland customers, alongside the power systems a desalinator depends on

Katadyn Group — FAQs

What does a Katadyn desalinator do?

It produces drinking water from seawater using reverse osmosis, forcing water through a semi-permeable membrane that separates out salt and contaminants. The result is potable water made onboard, reducing reliance on stored tank capacity and shore fill-ups.

What is the difference between the desalinators and the drinking-water treatment range?

Desalinators are for seawater, removing salt to make it drinkable. The drinking-water treatment range is for fresh sources of uncertain quality, common in expedition and overland use, where water is available but needs to be made safe to drink. Choose based on whether your source is salt water or fresh.

Can PowerSol help match a desalinator to my vessel's power system?

Yes. A desalinator draws power while running, so it needs to be considered within the overall power budget. Because PowerSol distributes both the Katadyn Group water systems and the energy and electrical components around them, the two can be specified together.
