CSN UltraZone / Sapphire Spas Clearzone - UV & Ozone Spa Santising System

$725.00 $799.00
Tax included Shipping calculated at checkout.


This is the Spa Sanitation system we actually use on our own spa. CSN UltraZone, also sold as Sapphire Spas Clearzone, uses a combination of powerful UV-C and Corona Discharge Ozone Spa Sanitizing System.

Installed after the filter, and returning at almost any point in the spa. (The deeper the return the better.) This has been very popular with people with skin conditions, and those that use a spa for long periods of time, such as athletes, jockies, and people with injuries.

UltraZone combines ozone generation with UV-C sterilisation. Ozone is generated via Corona Discharge and then injected into the UV chamber. The strong UV light reacts with the ozone to create a powerful oxidiser inactivating bacteria, burning off unwanted organic matter, resulting in crystal clear, clean water.
