The Onzen Salt Water system is Arctic Spas® proprietary salt water system that produces sanitizer from Dead Sea salts through the process of electrolysis. Salt-water
sanitizer generation has several advantages over traditional sanitizer methods.

Firstly, sanitizer is created, rather than added to the system and so there is very little on-going cost related to this system. The resulting spa water is much more gentle to
skin and eyes, and has a similar salinity to a human tear.

Onzen has many unique features that have overcome previous challenges tied to salt water systems for spas. The first is that Onzen has a use-rreplaceable electrode cartridge.

Electrolysis is a sacrificial process – the electrodes will eventually deteriorate and require replacement. The replacement of the Onzen titanium electrode cartridge
is a simple and inexpensive maintenance item that does not require the pool to be drained. The second key feature of Onzen is the ability to control the system either from the topside control, or via the Arctic Spas® smartphone App. This user adjustment can be used to match the sanitizer output of the Onzen system to the current, or anticipated bather load.

The use of the Onzen Salt Water system can significantly reduce the effort required to maintain clear and safe spa water, but we do suggest adding Peak I or II to maximize the benefit of the Onzen Salt Water system.
