The Katadyn Power Survivor 40 E ( 12V) is the world‘s smallest electrical desalinator.

Simplicity - The 40E contains 40% fewer parts than its popular predecessor, the PowerSurvivor-35.

Simplified construction and rugged design make the 40E remarkably easy to install, operate and maintain. Compactness - Extraordinarily compact, the 40E can be installed in the nooks and crannies otherwise unusable in many yachts. Efficiency - No watermaker draws so few amps.

Using only 4 amps, the 40E can run for extended periods on alternative power alone.

Durability - The heart of the 40E is the rugged stainless high-pressure pump. Armed for the rigors of the marine environment, this watermaker is built to last. We're so certain, we've covered it with a superior warranty: 3 years on most components. Special - The PowerSurvivor-40E is the only power watermaker that converts to manual operation in emergencies.

REVERSE OSMOSIS

To remove dissolved salts from seawater with reverse osmosis, part of the salt water is filtered through a semipermeable membrane. Only 10% of the water passes through the membrane. The remaining 90% flow past the membrane and at the same time cleans the membrane (self-cleaning effect).The small size of the “membrane pores“ ensures extremely pure drinking water, but extremely high pressures must be generated - normally 55 bar.

Reverse osmosis is used worldwide to obtain drinking water, e.g. in the semi-conductor industry and in medicine.
