Ya i just dont want the building, if it works for another 1.5 yrs or so ill walk away from everything inside. I could have it delivered if I wasn’t hiding in plain sight, for now its the best option. Even with big chiller of any source i like that i know what im getting with dry ice, and minions for dry ice runs is the best especially around lunch time.

This was my biggest issue I tried resolving when airgas was putting a cap on me for buying all their ice. I tested a chiller with a small run and after 2 days i was over it. The best part about dry ice is that when you need something to be cold you can instantly make it cold by tossing some pellets at it. The chiller takes quite some time to hit those temps. Just grind it out and keep getting ice. Don’t drop 100k and also upgrade the power only to potentially not do it for a long time.

Yes the outdoor unit goes outdoor it comes with a steel case, usually made to be mounted on roof tops but you could use it as like a central air unit and set it on the ground outside
5hp was fine, they have bigger ones too if you check their IG they have dual skid ones as well
I don’t get this conversation at all.
You can pay a lot of money for a high capacity chiller or make trips to buy lots of dry ice. But there is another option. Commercial dry ice machines are not that expensive to buy. Of course you would then buy carbon dioxide tanks and some filters but overall the ticket is not that large. You can make dry ice overnight and use it the next day. That’s what we do in farming and it works well especially at the more remote locations.
quick poll: are you guys
- CONDENSING with dry ice
- COLD EXTRACTING with dry ice
- BOTH
- NIETHER

If someone us using dry ice for their condensing coil or the like…it’s pretty safe to assume they are also using dry ice to chill the butane before it meets the biomass.

Permits for that would be the biggest expense, i looked into for an investment. The equipment wasn’t that bad it was all the permitting since it wasn’t way outta town

What, The, Fucking, Shit dude. What have you done!! !!! WHAT HAVE YOU CREATED!! ! ! ! EVERYONE NEEDS ONE OF THESE!!!
Omg omg omg omg OMG, am I a mad man or would this be prefect to have for a hot vapor loop? Like a smaller version of one of these… Holy shit.

Please note that is the MTA Italy site and the ratings of the chillers are based on 50HZ.
you can see the chilling capacity at 60HZ here

I get requests for low temp chillers all the time. The required temp is all over the map. As we all know the colder you run a chiller the less capacity it has. So as far as bang for your buck on capacity, there seems to be sweat spots. You wouldn’t want to get a chiller that has the ability to go to -60c and then run it at -20c. The break points in temps seem to be 0c, -20c, -40c. Each one of those operating temps would be a different model chiller. After -40c you really see a big drop off in capacity.

Care to share which Fluid Chillers AIR ULT units you’re using, and how quickly it can chill a given volume of ethanol? say, 40gals? our target temp is 50C and ‘hellacious’ chilling power is very compelling. considering them against Cryodax.
cheers

@nategeo We were using an AIR-20,000-2S-ULT-460/3
We sized it to be able to cool 1000 gallons of ethanol from ambient (~75*F) to -40 in 12 hours
We had it hooked to a brite tank and found that we had to agitate the brite tank in order to get everything in it cold, got it down to temp before 12 hours for sure
My main bitch with this chiller was that as sold to us in 2019 they insisted that we use an expensive coolant to maintain warranty, but the product they insisted on (Dynalene HF-LO) is some really nasty petroleum base stuff and it really softened up the (IIRC) silicone reinforced hoses connecting the fluid path inside the chiller - then leaked of course - they sent us a much better hose product after we complained about it and swapped that out and didn’t have problems again, but after it was out of warranty we just used denatured ethanol for the thermal fluid and didn’t have any more problems and CDA-12 ethanol is WAAAAY cheaper than Dynalene

yeah we’ve also found that ethanol is a pretty ideal chilling fluid, assuming compatibility with gaskets and hoses and such. remains very fluid at cryo temps, super cheap in comparison to a lot of purpose-made chilling fluids, etc.
thanks for sharing your experience with those units, i know i’m not the only one who will find that helpful
