The ACE® system contains a special diamond electrode that automatically creates five different powerful and effective cleaners for your hot tub from just a small amount of salt and your spa's water. When the diamond electrode is energised, it breaks apart water molecules to create active oxygen. Active oxygen is one of the world's most effective natural cleaners. One of the first ways the ACE system automatically cleans the spa's water is by using active oxygen. The active oxygen then combines with salt and other elements in the water to create chlorine and three other powerful oxidisers.
Since the ACE system automatically generates cleaners, you'll have fewer bottled products to measure and pour. This more hands-free approach saves you time, so it's easier than ever to care for your HotSpring® spa. To get started, just add the appropriate amount of salt to balanced water. Using the easy-to-navigate menus on the spa's main control panel, enter the size of your spa and your expected use level. Simply check the sanitiser level regularly with a test strip, and confirm your use level monthly. A status message on the control panel lets you know that the ACE system is cleaning the water so you can relax.
The ACE system generates the precise amount of cleaners your HotSpring spa requires based on its size and your use level. Since there are no excess chemicals, which often occurs with manual dosing, your spa water should last longer between changes. That conserves water and saves you money. When you do drain your spa, the water has less impact on the environment because only salt has been added to the balanced water.
The ACE Salt Water Sanitising System leaves your spa water sparkling clean and silky soft. The cleaners are generated from salt and water, so you're less likely to experience the dry itchy skin, irritated red eyes, or harsh odour caused by traditional chlorine water care.
Traditional salt water systems use titanium electrodes capable of producing only chlorine. The ACE system uses a unique solid diamond electrode along with two titanium electrodes. The patented diamond electrode increases sanitising power, while using less salt, and generates 5 different cleaners instead of just chlorine.
The diamond electrode in the ACE system generates high-energy active oxygen from water. The first way the ACE system cleans the spa's water is by using active oxygen. Once the water is clean, the active oxygen combines with just a little bit of salt to produce 4 more cleaners: chlorine as well as ozone, hydrogen peroxide, and MPS. (Note that MPS generation is dependent upon having pH down present in the water.)
The ACE system is currently an option for HotSpring spas built on or after August 5, 2009. Contact your local HotSpring dealer to find out if your HotSpring spa is compatible with the ACE system.
As in the case of bottled chlorine, chlorine generated by the ACE system is sodium hypochlorite. However, bottled chlorine contains stabilisers like cyanuric acid. When bottled chlorine is repeatedly added to spa water, the cyanuric acid can accumulate over time, causing irritation to the skin and eyes. With the ACE system there are no stabilising acids added to the water so the water is gentler and more enjoyable.
The ACE system cleans the water with Active Oxygen first, without creating chlorinated or brominated by-products. These by-products are what ultimately lead to the strong chlorine or bromine smell often associated with traditional spa water care. It is less likely you will experience any strong chlorine odour when using the ACE Salt Water Sanitising System.
The ACE system automatically generates powerful cleaners and the required sanitiser chlorine needed to keep spa water clean and safe. In so doing it eliminates much of the daily or weekly water care requirements of traditional systems. As the spa owner you are still ultimately responsible for the safety of your water and must be sure to do all of the following:
Table salt is not recommended for use with the ACE system because it contains iodine and anti-caking agents that will interfere with the ACE system operation and may cause staining of the spa shell. Salt for the ACE system is available through your local HotSpring Spas dealer.
On average, the salt level of tap water is around 500 ppm. The target salt level for spa water when using the ACE Salt Water Sanitising System is 1,000 ppm which is virtually undetectable by taste or smell. For the sake of comparison, the salt level in sea water is approximately 35,000 ppm.
Pool systems use up to 5,000 ppm of salt. High salt levels, like those used in a pool, combined with unstable water in a spa, can corrode equipment over time. The unique diamond technology used by the ACE system allows salt levels to be at a minimal 1,000 1,500 ppm, which helps prevent corrosion.
