Carbon dioxide Feed systems
The CO2 feeder is a mixing device that mixes the CO2 gas with water in an effecient way, so little CO2 gas is outgassed into the athmosphere after the CO2 water mixture is leaving the feeder. CO2 is the easiest gas to dissolve in water, followed by arragon, oxygen, hydrogen, and nitrogen, based on the calculations of Henry's Law.
Carbon Dioxide CO2 is a natural non-corrosive gas that can be used as a substitute for other acids (such as Muriatic acid HCl ) in chemical treatment of spas, saunas and swimming pools. When CO2 is dissolved in water, it forms carbonic acid H2CO3, a weak acid which can be used to lower the pH of water and neutralize liquid chlorine.
CO2 is available in standard pressurized gas cylinders.
