What is the latest in VO Processing

Postby Radrick » Wed Mar 12, 2008 11:23 am

I have been reading threads for months and months on CF's and processing rigs. After a while you can't keep the timeline strait in your head and all the idea's new and old get all mixed up. My next move is to start ordering stuff for my wvo processing setup. I have a few questions related to this.
1. Is the origanal setup that sun has still the best and only process required? drum with funnel bottom, pump capable of .9 gpm at 90psi mounted below the level of the bottom of the drum, two 220v water heater elements run on 110v mounted in the pipe up the side of the drum, and a dieselcraft CF mounted over the drum that you catch the output of as you shut down the pump.
2. I was reading the shread on this site about using plastic drums instead of steel. Would it be worth trying to setup my rig with a plastic drum? I would rather not because it would be hard to have a very good low point for water. the vo will not be in there long and you can't seal it anyway.
3. Which CF is the best bet and least expesive? Where is the best place to purchase it? and are there any discounts for members? I have read so many answers to these questions and they are over such a long time period that i am confused.
4. I have read a couple of posts about bad things happening because of lose of flow. Is there enough of a risk factor that I should incorporate some safty devices to ensure that I don't burn down my garage? If so what is the best way to do this, t-stat or flow switch?
5. I have read several posts were people are water washing there vo, draining off the water, and then running the CF. Is this the best way to process? Is this to remove minerals like salt?
6. I have an old hydrolic pump if i control the speed of the pump with pullys is it pretty easy to get in the range required or do I need to buy a pump?

I know all this information has been given in the past on the other site but as I said I am confused and tired of reading and since i wasn't on these sites for most of the time the system was figured out it is very hard to keep it all strait while reading back on several threads. Thanks in advance for any help.

There are many ways to get clear dry VO

The simplest, and least expensive gravity settling/filtering systems will produce about 50 gal per week, like this one

If you want more oil, quicker, then pumps and centrifuges are the answer.
Here's a simple pumped unit.

Most of that is answered in the summary link at the top of page 1 of the dieselcraft thread here.

1. Yes.
2. Not worth it.
3. Dieselcraft= best, but not cheapest.
4. water heater t-stat is the cheapest safety device.
5. Mistwash is not needed after much testing, see the summary.
6. that depends on the size and flowrate of the pump, small ones are best.

Thanks Sun I know alot of this is in the threads hear. I did take the time to read the info on mistwashing. Is the best place to get dieselcraft direct from them? Is there a discount to members of this forum or the other?

Check out the Spin Clean II (now Filterfuge?). Seems like a much better deal than the Dieselcraft these days and does the same job from what I read.

Did you know there are adjustable pulleys where the diameter can be changed?

Spinner centrifuge on ebay:
http://cgi.ebay.com/ebaymotors/ws/eBayI ... 0225495228

Caution: Note that the seller is new, with no feedback. Beware of scams. If this isn't a scam, someone could get a good deal on those. The wording is vague, but it appears he is selling 3 of them for 1 price.

The dieselcraft is about the same $ from everyplace now, I think they ended the forum members discount now that its gotten popular, but you could call and ask.

ARRRRGH!!! I wish I'd seen that before the auction closed! Great deal! (assuming it wasn't a scam)
