Water Flow Speed

[Andylit]

What is recommended for the most efficient chlorine generation? Fast flow? Slow flow?

Are there upper and lower limits?

I'm running a variable 3HP Pentair through 2" pipes. My heat pump wants the fastest possible flow for the best heat exchange efficiency.

What does a SWG want?

Andy,

As long as the flow is enough to close the flow switch, then it makes zero difference... A SWCG generates the same amount of chlorine, no matter what speed you are running..

In my mind, the lowest speed you ever want to run is the speed that closes your flow switch plus 100 RPM.. For me this is about 1200 RPM.. But I don't have a heater.. With a heater it would probably be more like 1600 to 1800 RPM..

Thanks,

Jim R.
