Falling film temperature

you could always pose this to @TheGratefulPhil

if you’ve got any additional data from the manual that came with your machine. such as how much cooling, or evaporator/HX surface areas, you might be able to math to the correct boiler temp.

yep…and by adding that 30% margin, you don’t have to be too worried about hitting the same delta-T and flow rate the OEM intended. sounds like you got this. :wink:

Here is the manual for the FFE. I thought maybe you wanted the heater manual instead.

Wow! very impressive knowledge he has… :+1:

THAT looks more like a Chinese knock-off FFE.

the flanges are a dead giveaway.

looks like a fun read…

It definitely is. everything seems to be built pretty heavy as far as material. i purchased this from china before Delta had a patent

China companies don’t give a shit about patents :joy:

Probably true but just stating that this was bought 3 years prior to when Delta filed for theirs. i bought a china knock off of the cup-30 at the same time and in comparison, im afraid id take the one i bought from china…

Well, if it’s not sitting in the corner gathering dust… Then I would be inclined to believe, that yes, yours is in fact better!

I didn’t read a lot… It’s… Not the best written manual I’ve ever read

The TLDR; lazy rule of thumb is 20-40-60. In other words, your boiling temp should be 20 degrees C below your vapor temp (ie superheat) which should be about 20C below the condenser temp. Usually the cooling is the annoying expensive part so that’s the constraint. Lower chiller temps cost more to run. Our facility chiller runs around 6C so for us we run a 46C boiling flask if we only care about speed (decarb happens so that’s another story). Clearly, a water heater can provide 46C water and then you just set the vacuum level as necessary to drop the boiling point to 46C. Fyi this is based off rotovap principles but no real reason it would be different for an FFE.

Wait, show us a picture of your unit…

china makes some very accurate delta clones.
you’ll probably need all 45kw blasting at it to reach close to advertised speed target (which becomes way lower with goo in the tubes)

if you’re brave you’ll enjoy the extra heat oil can deliver vs water or steam.

Definitely not the best ive ever read either. Glad i gained knowledge of running other ones in the past. Thank you for your input here as everything helps. i think a gas fired boiler would really do the trick to keep things close to the OEM side of things.

Ha! Exactly! Its why im here. Ive had good luck with china,s products regarding processing equipment but when it comes to instructions and such, its on the poor side. in fact when i bought my 6 inch short path, they sent me a cold trap for dry ice…i earned a nice coil cold trap for making the company a video for American assembly. Nice Bonus it was… :+1:
