Hey guys… awesome community, happy to be a part of it.
We’ve been operating off dry ice slurries for years now, and are over it…
I’ve calculated out our cooling capacity needs for our given volume (BHO, 70/30), and…
HUGE SHOUTOUT TO THE ULTIMATE CHILLER CALCULATOR CONTRIBUTORS!!!
but anyways. We need 5.2 kw @-40 for our needs.
Better safe than sorry, so I was thinking 6kw as a I research options.
It seems like a Huber or Julabo unit will run about ~100k(very rough number)
Mydax/crydax units are waitlisted for 4+ months. (50-70k)
I stumbled on West Tune units(Chinese manufacturer), which are awfully affordable. 2.5kw@-40C for sub $10k…
This got me thinking. There are still ample technical issues with the expensive German units. And if we can only afford to buy one, without a backup…Mechanical issues=downtime.
soo, I wanted some thoughts from the community.
1.) Is it possible, and if so effective, to chain chillers together(our system has multiple heat exchangers, so I could possibly run them individually to their own chiller)… But do 3x 2.5kw@-40 chillers equal out to ~1x 7.5kw@-40 chiller?
In the event the above question is remotely feasible, there seems to be some upside to running multiple units.
the first being price… 4x Chinese units is sub 40k. which would allow for a backup onsite…
2nd. In the event one, or even 2 of the Chinese units encountered an issue, we could more than make up for lost cooling power with a dry ice slurry…
3rd. The units are cheap enough(and come with a 1 year warranty through an American service company, that in the event we needed to we could probably troubleshoot and cannibalize units to keep 2-3 units operating at any time.
I mean… again. if 3x 2.5kw@-40 units =1x 7.5 kw… then we could literally buy almost 11 of them for the price of one comparable huber…
I appreciate any/all input.
