A local SW hobbyist was a little sceptical how well these would work. He paid $400 for a RO/DI and wondered if these were good units or what. Does anyone on here have one of these besides jbeck?

I bought mine in August and it works great. 100 gpd unit that jbeck has. jamesurq's unit is from the same company.

i like my RO/DI from www.airwaterice.com
it's the 100gpd five stage it has the clear DI cart. holder so you can see the color change on it so you know when to change it

 

[jcsurfn]

What is GPD is it gallons per day? What does this actually mean?

 

[javatech]

Yes it's gallons per day and that's the output with the best water temp and psi that is 70-80 deg and 50-70 psi

 

[jcsurfn]

So then that is how much water it can put out a day? Also why do they mesure it in a day?
Thank You

 

[jcsurfn]

Also you run the water through the unit at the temp. you want? and wat does psi have to do with it? I know maybe a dumb question but I am a little confused.

 

[javatech]

If the water psi is too low the unit will make more waste water also if it too cold it will make more waste water. it will work and the water that it makes will be fine it just won't make as much as it should. If you have fifty degree water at ( 50 ) p.s.i. expect half the rated production.
