One way to concentrate oxygen from air is through a process called pressure swing absorption (PSA).In PSA process a molecular sieve takes in water and nitrogen from the air with oxygen left out in the gas stream. Oxygen concentrations of 90-95% are attained. PSA process can be in small scale, for oxygen breathing or large scale for industrial use.
Generator produces heat that needs to be cooled. This can be done through air or water cooling. Water cooling is a more efficient means as it increases the size of generator that can be manufactured. Water cooled systems appear in quite a lot of variations. There are closed loop systems that make use of water chillers and recycle it in the generator.
There is also an indirect cooling loop that utilises ground water. Choice of water cooling systems and chillers is founded on an engineering study for the purpose of assessing larger generator size and chilling water costs.
Manufacturers often set a precise operating temperature for generators at 68-72 degrees Fahrenheit. If it is above the specific temperature, say 82 degrees, for example, it results in a production fall.
Here the generator can shut itself down to avoid damage.
- Identify the application with awareness of the volume and concentration of ozone necessary. If not aware, contract with a competent laboratory or engineering company to undertake the required studies.
- Be sure to compare ozone creation of various generators at similar ozone concentration to have fair price comparism.
