Falling film temperature

You definitely caught me off track on my thinking. It states in the manual that it operates at <0.5mpa. When the heating temp is 300c, the operating pressure is only one seventy of the saturated vapor pressure of water. flow is 10m/h.

Yes! one outlet in and one out…It runs with a vacuum pump. So you recommend a mix and not full oil?

If u already have the oil use it, gives u more versatility. But if u dont, dont waste money and just go with the water mix. Worse case scenario u need a 1-3 gallon expansion tank, i did it for reassurance. But ive seen many not worry about the expansion and just plumb everything directly

Depending on ur vac id lower my suggested values by 20F or so.
Flow is what? m/h? Idk what that means

Thanks for your input as well. the unit has its own 20 gallon expansion tank and all the safety sensors as well. im just hoping i can replace just the heating unit with a gas fired unit to avoid paying my power company 40k to drop in power. i converted 45 kw over to BTU which comes out around 150,000. so im thinking of purchasing at least one that is around 200,000 to make up for the loss of efficiency if that makes any sense.

on the off chance that I’m not the only one using a browser that doesn’t grok .webp files…

um yeah, nope. don’t think you wanna run 300C silicone oil into that without exploring safer places first…

Edit: which might be as close as the manual for delta’s machine, which this looks uncannily similar to. @Kingofthekush420 might have delta’s operational parameters close at hand.

or one of the other folks discussing how to use one “off label” over here: Is it possible to Decarboxylate in Delta’s FFE45?

Thats what i was afraid of. I didn’t want to throw myself into the next state.lol
i have sent questions to the manufacture. .Awaiting feedback, but getting better answers here.

cubic meters per hour i believe. China uses the metric system that i really dislike. Comes out to 4.4 gallons per minute.

Thanks for your info Cyclopath. ill ask @Kingofthekush420 what his perameters are and see if that will help.

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…
