Can any Spa be a Salt Water Spa?

The simple answer is No.

Everybody knows that salt is corrosive for metals and as such superior materials are required for our exclusive salt water spas.

Salt at the correct concentration will not damage our superior Shells, Jets, Pumps and Other Equipment.

 

It’s not Sea Water

When we think of salt water, the ocean usually comes to mind. Sea water has a strong salty taste of course, and it can cause metal corrosion. So you might be wondering if salt systems are safe for spa equipment. Fortunately, the levels of salt used within our endless systems are very low by comparison, and safe for equipment.* The table below shows some approximate saline levels to give you a perspective:

 

Salinity Comparison – Parts per Million

  • Ocean Water 35,000 ppm
  • Human Tears 9,000 ppm
  • Ability to Taste Salt 5,000 ppm
  • Endless Salt Water Spas 3,000 ppm

 

How a Salt Water Spa System Works?

A salt chlorine or bromine generator is incorporated into the filtration system of the spa. A generator consists of a control unit and a salt cell.  The type of generator chosen depends on the type of pool/spa chosen. (Picture below shows an in ground pool system)

Every time the filtration cycle is engaged the chlorinator turns salt into the sanitiser for free. Salt is sodium chloride (NaCl). Through a controlled process in a low-current electrolysis cell, chlorination is produced in just the right amount to sanitize spa water.

As salt water enters the cell, a safe, low-voltage current passes between special rare-metal plates, producing pure chlorine (Cl) from the saline solution. In water the chlorine instantly becomes hypochlorous acid (HOCl), which is its disinfecting form.

In conjunction with its control unit and programmable timer, the cell will sanitize any size spa. It is incredibly efficient, using only about as much energy as a 50-watt light bulb, often running less than an hour a day.chlorinator-diagram

 

 

 

 

 

 

The Salt System: Recycles Itself

You’re probably wondering how often the salt needs to be replenished. One of the beauties of these systems is that as the hypochlorous acid is used up, the chlorine recycles back into salt. So with a salt chlorine generator, the salt only has to be topped up occasionally due to spa water splash out, and replenished when the water is changed. Very economical!

 

Endless Salt Water Spas are designed to appeal specifically to Spa users concerned about the effects of chlorine and includes:

  • Smoother, softer-feeling water – Feels amazing on your skin, not like chlorine
  • Less odour – Smell like the beach, not the pool
  • Gentle to hair, even coloured or blonde – No more green hair!

While some marketers tout salt systems as chemically free, that’s really not honest advertising and misses the point. This is a world of chemistry, and life itself could not exist without chemicals. Salt is a chemical. Water is the most common chemical on our green Earth’s surface! Salt systems are an advanced method to utilize natural chemistry in a better way.

Many people previously convinced that they had an allergic or other aversion to chlorine, found no such problems after switching to a salt-based system. Perhaps the additives in packaged chlorine were more to blame. In any case, a salt system allows the user to more precisely control the sanitizer output, often requiring lower levels to achieve water purity. The mineral salts have many health benefits of their own.

Another benefit is the spa owner doesn’t have to dump water as often compared to chlorine free or traditional chlorine / bromine systems. Less dumping with a salt water spa saves you time and money. You do not have to refill (water and chemicals) and heat the spa from scratch.
