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
Onzen has many unique features that have overcome previous challenges tied to salt water systems for spas. The first is that Onzen has a user-replaceable 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 tub 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.
*If you want both Onzen and Peak II systems in your hot tub, you will need to have the Eco-Pack control system installed in your spa.
