SmartChlor

Trade loose spa chemicals for simple cartridges

Spa water maintenance has never been easier than with the SmartChlor in-line sanitising system: just change a cartridge! No more loose chemicals and guesswork – the ideal amount of chlorine is gradually dispensed to create perfect spa pool water.

Automated, set and forget water care

SmartChlor delivers time-released chlorine only when your spa pool needs it. Choose your preferred level, and the system will identify when more sanitiser and minerals need to be released. A consistent <1.0 ppm chlorine level means softer water, less odours and no fabric or surface bleaching.
