We are pleased to offer custom refrigeration solutions which are optionally ETL(Intertek) listed. We can build from 2.5-200 tons and as low as -80 Deg C.
Systems are 100% USA built with USA/German parts for minimum downtime and maximum ROI.
Currently we are focused on smaller units at 2.5 & 4 ton capacities rated for -48 Deg C (but can reach -60 Deg C), in a flooded heat exchanger configuration or pumped glycol configuration.
In the flooded heat exchanger configuration the ASME heat exchanger sits in the extraction room and receives refrigerant from outdoor skid mounted condensing unit, for ethanol this corresponds to chilling 200 liters/hr (2.5 ton) and 320 liters/hr for the (4 ton) from room temp down to -48 Deg C. (other solvents could be used)
In the glycol pumping configuration the heat exchanger is installed outdoor and pumps the refrigerated glycol/Dynalene into the extraction room to whichever process or system requires it. (Minimum coolant temp -43 Deg C, expected minimum process temp of -38 Deg C due to pumping & heat EX losses)
Heating loops using waste heat recovery from the condenser are also possible.
Pricing available via request, DM/Email for details and quotations.
Welcome @GreenProcessSolution ! I know i need a new chiller or two. I bet lots others do 'round these parts too! Id love to consider a usa manufacturer. You should post a a general pricing sheet so we can get an idea of what systems cost from you vs. our other optionsā¦
(ETL listing of entire unit onsite after install, +$9000)
Pricing is equivalent for flooded heat exchanger (FD) and pumped Dynalene (DYN) units of equal tonnage
Power Requirements:
2.5TR UNIT: MCA 49AMP, MOPD 70AMP
4TR UNIT: MCA 74AMP, MOPD 110AMP
Note: amperage provided at @3x480V/60hz, double for 3x 208-230/60hz
Still working on refining my documents, completed cut sheet will be up soon.
On the basis of tonnage alone our systems are quite expensive, however one should consider the level of quality and sophistication, UL stamps on every electrical panel and heat exchanger, and continued support offered for a custom product.
Going down to these low temperatures is difficult, for vapor recovery alone there are many other mass produced UL-listed units on the market which are cheaper (but do not go down to as low a temperature).
I would argue when one considers the full ROI of our system we come out on top, as well as actually meeting our stated numbers.
Oof. Still pricy just like the cryodax units. How come china is able to make these DSLB -120 units and move them for 9k? I get domestic is always more expensive but this is on another level.
-86 C would require switching from R-507 to ammonia refrigerant a significant change in technology.
If this is a serious request I can look into it, probably not a huge difference in price.
How much tonnage would you need at that temperature, would be my main question, for a smaller system it would likely not be worth it, at scale it may make more sense.
The main issue is the certification, if I recall the touch sciences units are CE(Europe) certified only. And like I said comparing tonnage numbers vs. the actual delivered performance and ROI is complex and needs to take into account glycol pumping and friction losses, heat exchanger efficiency etc etc. China is always ācheaperā on paper.
It would be helpful to know what you are trying to do, how much solvent you need to chill per hour etc, and make a comparison based that.
Depending on who is certifying your lab ETL/UL listing is likely required and regulations will only get more strict. (i.e. working with PSI Inc they only allow USA/UL/ETL certified chillers)
The other issue is actual delivered tonnage at target temp, for example see the specs of the similar touch sciences DLSB-30/80 below:
The touch sciences power drops off significantly at -80C, our system is designed to deliver the full power at the rated temperature (-48C), with the minimum temp of -60C at no load.
maybe you can shed some light when you get a sec ben @TouchScience? Be good for you to join this convo too, so long as @GreenProcessSolution dont mind that is after all, it is their threadā¦
Youāre right, the power drops off, but itās got significant power at -40 and -80, and it goes down to -120 which I havenāt seen any domestic chillers at all do. I would be really happy to get one of these very same units, but certified. And itās only 15K. Canāt we it made with UL parts and be sold for say 3x price? 45K would be pricy but it would beat the pants off of mydax, thermonics, and others.
yes, you need to be colder than -48 in the process (the extraction part) otherwise you over-extract (with ethanol). the difference between -48 and -86 would be in your post processing. at -86, send it on its way for solvent removal. at -48 add 24 hours for winterization plus pushing through a carbon filter for color remediation. so it is a huge deal.
Ok I will look into this, approxx how much power(tonnage) would you think would be needed for the first model, equal to the dslb-120 would be ~ 1.5 tons?
My thermo is more or less non existent at this point in time. However there are many smart people on here who have this type of info. My knowledge ends at āi need to extract very coldā lol
Could I use a Robinair automotive a/c service machine to pump refrigerant in and out of column jackets to control temp? Anyone? Seems like an interesting project.
so long as you have a way to dump the heat you generate upon compression.
and do the maths right (I hear there is a calculator that makes that bit easy)
you could probably use your CMEP-OL and pump R600A
