Water became brown color...overheating??

hey guys to be clear, he didnt say it actually overheated. He hasnt really given much info here

Thanks guys,

I put more information and two pictures of the cell.

We did clean the system several times, but the same problem repeated again and again…It worked 8 hours a day, but the brown water showed up in 2 days.

Water temperature of the system, will be max 48ºC (may have a peak of 72ºC) at 22ºCelsius to 27ºCelsius room temperature.

When we tested the system with a small car, it worked well. But it doesn't work properly with caterpillar and truck. We are now checking what was different between those.

The truck:
Volvo 380 12.000cc Turbo diesel
Net weight 7,9Ton
Gross weight 40Ton
1100 - 2750 rpm/minute

We checked the connection, water, electrolyte, cleaning. We think it was correct. We doubt the plate is not good quality…we are thinking about buying a new cell. Should we do it?

We used this cell:

* 21 Plates of 316L Stainless Steel Plates
* Demensions: 19*19*11 cm
* High temperature Cast Acrylic end Plates
* Four 3/8" 90 Degree NPT Elbows with Hose Barbs
* Two NPT 3/8" True "Y" with Hose Barbs
* 2.5mm Neoprene Rubber Rings
* Net Weight: 4.9kg
* Our Dry Cell is expandable.
* Stainless Steel Plate size is 15.2*15.2 cm (6*6 inch).
* Plate`s thickness: 1mm (brushed)
* Production: 2LPM to 10LPM.
* Working at 12v to 35v, 10amp to 70amp.
* Fittings including: 2pcs of 1/4x3/8 Elbows, 2pcs of 3/8x3/8 Elbows, 2pcs of 3/8 True Y Connections, 8pcs of Hose Clamps, 4 sections of high presure pipe

Thank you for your helps!!

It looks like we have covered most any possibility. All that is left is certification of everything that is in the Electrolysis Generator (Egen) or going into it (electrolyte and water).

Are you sure you have 316 SS plates? Is your electrolyte pure? Is your water really steam distilled? At this point this is all I can advise.

Don't worry about the heat. It has nothing to do with brown sludge production. I run my cells at 80 deg C for long periods of time. It is more about the current and driving voltage rising above the recommended levels and undoing your passivation (conditioning) and causing the iron in the stainless plates to corrode as the chromium transfers away. You may want to dismantle the Egen and check to see if you are getting any corrosion or etching in the plates.

Hi RustyLugNut,

Thank you for your advices. Your experiences help us a lot.
We checked electrolyte was pure, we used distilled water!!
and Cell for the small car worked well: Cell has 11 plates, 1,5l water deposit, It works at 12A, It produces 0,5 liters per minute
Cell for the truck had the problem: Cell has 21 plates, 3l water deposit, It works at 27A,It produces 3 liters per minute

So we think the 316L SS plate for the truck was not good quality. We will get new cell from a trusted company.

Thanks!!

any chance this things on a 24 volt system?
