Strange. By their own words, they definitely do elctrolysis of sodium
chloride (snipped from raritan web site):


The process starts with salt water in the treatment tank. NaCl --
Na+ + Cl- Sodium Chloride is a strong electrolyte so it exists in
water as sodium and chloride ions.

H2O -- H+ + OH- Through hydrolysis, water breaks into hydrogen ions
and hydroxyl ions.

The electrode pack is energized during the treatment cycle and
electricity passes through the conductive salt water. Hypochlorous
acid, a powerful bactericide and oxidizing agent, is produced on the
surface of the plates.

At the Anode: 2Cl- + OH- + H+ -- HCl + HOCl + 2e- Hydrochloric acid
and hypochlorous acid are produced, liberating two electrons.

At the Cathode: 2e- + 2 H+ + 2Na+ + 2OH- -- 2 NaOH + H2 The two
electrons, hydrogen ions, sodium ions and hydroxyl ions combine to
produce sodium hydroxide and some hydrogen.

The Net Reaction is: 2Cl- + 3OH- + 3H+ + 2Na+ -- HCl + HOCl + 2NaOH +
H2 With constant mixing from both motors, the products are mixed
together for continued reactions.

NaOCl + H2O -- NaOH + HOCl Hypochlorous acid (HOCl) is formed when
sodium hypochlorite reacts with water.

HOCl + XXXX -- HCl + XXXXOx Hypochlorous acid reacts with soil, dirt,
and bacteria giving up its oxygen; leaving hydrochloric acid.

HCl + NaOH -- H2O + NaCl The hydrochloric acid reacts with the sodium
hydroxide to form salt and water.

The usual explanation of reactions in a sodium chloride cell is this,
and I wonder how they make the reactions above happen instead of the
ones below.

Sodium hypochlorite/chlorate manufacturing process:

Electrochemical and chemical reactions occurring in cells
[1] 2Cl- == Cl2 + 2e- (anodic reaction)
[7] 2H2O + 2e- == 2OH- + H2 (cathodic reaction)
[8] Cl2 + 2OH- == OCl- + Cl- + H2O (hypochlorite formation)
[9] 3OCl- == ClO3- + 2Cl- (chlorate formation)
[12] NaCl + H2O == NaOCl + H2 (overall hypochlorite reaction)
[13] NaCl + 3H2O == NaClO3 + 3H2 (overall chlorate reaction)
[14] 3Cl2 + 6NaOH == NaClO3 + 5NaCl + 3H2O (chemical chlorate
formation)
