HPA Setup Question

And still wasting my time with information I already know from many years ago. Still haven't answered my question. How do I keep my nutes cool enough with an accumulator tank inside my 80 degree room? Without breaking the bank...

If your pump is drawing nutes from a res/tank. You could just recirculate that tank through the chiller with a small mag drive pump.

A mag drive pump and an accumulator don't play together. I'm pretty sure atomizer already said it, but you run a coil of tubing post-accumulator/pre-solenoid, into a cold water bath. A mini fridge comes to mind. Or simply use your tap water, if it's cold enough. Locate your accumulator outside of your 80 degree room, if possible.

The mag drive and the accumulator wouldn't be playing together...

The mag drive would only be used for the chiller...independently of the HP system.

I agree that a chiller is really not needed, but thats what the OP wants..

If you ran your chiller into a smaller accumulator (that discharged every hr or two) the chilled nutes might stay cold long enough inside to be effective. You'd wanna insulate the hell out of it though.

Correct that's my current setup
I would love to get my chiller out of the equation and not need a return to my Rez many reasons I want to look into this

Why not just use frozen water bottles in the rez? Or move the chiller outside your grow room if heat from that is a concern?

Or if keeping the accumulator cool is the goal, use the chiller to cool a coil around the accumulator then insulate it.

Why does it matter if the temperature of the nutrient solution in your reservoir is 80 degrees? Why do you want it to be 68 degrees?

Accumulators used for hpa dont need active cooling, the chiller coil will also affect the air precharge pressure. The next thing will prolly be how to keep the nutes aerated in the tank so they dont stagnate Probably best just to stick with a recirculating res cooled by a chiller, driven by a pump.
@JB
+1 High pressure aero mist made with 80F water wont be a cloud of 80F mist, it`ll be considerably cooler.
