Reverse Osmosis Controller

Q

As anyone here ever replaced their reverse osmosis controller?
I need to replace the one on my syncro unit. Need some Ideas.
Thanks
 
I don't know what a "reverse osmosis controller" is. My unit has a float switch that turns on an electric motor connected to a Procon Pump. There's also an adjustable delay so that the system gets "utility water pressure" before starting.

The only thing I've replaced in 15 years is the motor contactor. Is this what you mean?

I have a PLC progam for an RO controller. It uses an Automation Direct 05 Series controller ( get from Automationfdirect.com ) There $99.00.

If you would like the program id be happy to get you the source code for that at no charge

ONEcard I sent you a email with more questions about the PLC.

Rudy my controller does a back wash and reads water quality.

Thank you both for responding to my post.
 
I replaced one on a syncro 1000. I got it from Huron Valley Sales. It was about five years ago, and it was almost $300 then. Ofcourse, nobody repairs the old ones.
 
You don't need the backwash function and you can get a handheld TDS meter for about $20.
 
First, it's not really a backflush. It just rinses the membrane at a higher flow and no pressure.

Second, I've been doing this a very long time and have seen lots of different systems, and the flush doesn't appear to affect the life of the membrane at all. It's more about the quality of the water going in that matters.

Thanks for the comments. My system does run the motor on backflush.
I have 3 RO units 2 of the units which are newer do the backflush.
I can build the replacement controller myself but if the backflush is really not that important it would save some time and money by not including it. I just want to do it right.
 
Go with MEP's advice. The backflush isn't needed. In many instances manufacturers will add some device or function to a system just so they can say, "Our system does this, and golly, look at the advantages."
