So you want a reservoir full of DI water, AND you want to avoid the effects of TDS creep (shortened DI resin life and high TDS water reaching your reservoir) AND you want the RODI system to turn on and off automatically?

Buckeye’s new Hi-Lo Tank Level Controller solves the problem!

This auto top off solution includes two float switches – one installed low in the reservoir, and one installed high. The system can be used to open a solenoid on the RODI feedwater tube when water in the reservoir drops below the bottom float switch. The system will then cut off when water reaches the upper float switch. This configuration avoids short-cycling – the constant on/off cycles that prematurely exhaust your DI resin and deliver not-so-clean water to your reservoir.

You end up with a reservoir that remains full of DI water, maximum life on your DI resin stage, and minimum TDS water delivered to the reservoir.

Feel free to give us a call to discuss how the Hi-Lo Tank Level Controller can solve your situation.

Having a little trouble picturing how you'd set up the Hi-Lo Controller? Here's a graphic that depicts a typical configuration where the Hi-Lo controls a solenoid on the RODI feedwater tube.

You can find our solenoids here:

The 24V solenoids can be powered by any of the transformers on this page:

Having some issues with this. How do I mount this on a tank. I have a plastic holding bin to use for top off water that can be easily drilled. However once I make the hole how do I get the switches in? Since they don't detach from the bulkhead they come with, in order to fit the entire switch through drilled hole the hole ends up having to be too big for the bulkhead to cover.

Great question! I can tell you've really thought about the installation.

The trick is that the kit includes float switches that mount from the outside of the tank, rather than slip through the drilled hole from inside the tank. They are really slick.

Why is there a 24" max between the float sensors? Can I install this on any size reservoir?

That is based upon the default length of some of the wires. If you have an application that needs a greater distance between the floats, let us know and we can accommodate that.

One other thing I should mention here - the Hi-Lo Controller is ROBUST! If your situation calls for the device to control a pump rather than a solenoid, realize that the Controller can handle up to 12 amps. That's a big pump!
