cf filtering ?

Postby gary » Wed Dec 10, 2008 10:49 am

For cold settled vo

I pour until I see the white emulisified mix on the bottom try to pour out and than i stop.

If there is 10 gallons I go for 50 min at 160f at 90 psi

? is am i supposed to stop and clean my cf and start again because I never do that.

It then gets pumped through cimtek polishing filter into vo car tank.

Trying to figure why I only got 2-3k on my 1st vo filter.

Thats not that bad, it could be due to lots of things, we would need full details about your conversion and CF rig.

It could be your vehicle isn't providing enough heat before the filter to liquefy PHO and fats.

Did you do a hot pan test on each batch?

My rig...all coolant heated...heated pickup-tih,full return-heated filter jacket-fphe-two valves and ip.

my oil is good canola that I settle and never pour the last of the bucket in
(white junk or brown junk)

I swictch over when coolant is at 180ish and its a slow climb to my max veg temps of 171 when coolant is at 196 after about 20min of 80mph driving.

I forgot to mention I skipped hot pan testing on the last 3 or4 batches because of my cold setteling and extra time on the cf.It also smells up my whole house cause i do it in the kitchen...only a tablespoon.

Also about 5 weeks ago I put in one of those McCormick red food dye viles to test purge times and relized that was water!

That would plug a filter, just hope it didn't do damage beyond that.

cf ?s

Postby gary » Fri Dec 12, 2008 12:41 pm

How long should it take to heat 25gals of oil to 160 starting at around 50f and the air temps in the mid 40s with the two 220 elements wired for 110 as in your system?

I start cfing when the oil feels warm and work the bypass till im at 160 and bypass off for 90psi....or am I supposed to just go through bypass till 160?

And does the time start for four passes at the 160 temp?

Also what is the pressure rating for that cimtek filter because I did not set up a gauge with a bypass for that.

Thanks

I start CF at 120F at CF inlet, which is about 30 mins for a 50 gal. batch, so should be about 15 mins for 25 gal. It reaches 160 after about 2-3 hours, so yours should be about 1 hour.

Same as me, but I don't know what you mean by "work the bypass".
or am I supposed to just go through bypass till 160?

No.

No.

50psi is printed on the side of mine.

I close the bypass valve(work the bypass) as the vo temps increase to maintain 90psi at the cf even though im not yet at the target temp of 160.
