ACE® Salt Water Sanitizing System

Low-maintenance Saltwater System

A Clean and Comfortable Spa


The ACE system uses a patented diamond electrode that creates active oxygen. Because cleaners are automatically generated from salt and water, spas with the ACE system lack the odor of chlorine and require fewer harsh chemicals that can irritate skin and eyes.

Save Time On Maintenance

The ACE system automatically generates cleansers in your spa water. This more hands-free approach saves time, so caring for your Hot Spring® spa is easier than ever.

Use Less Water

Because fewer products are added, the ACE system allows spa water to last much longer than traditional water care. This means that you’ll drain and refill your spa less often, conserving water and saving you time.
