Big Cascade (not yet finished)

[Kevin Hotton]

I work for a company that makes some interesting equipment. This is my largest Cascade Refrigeration system so far. It is not yet finished. It uses two Vilter 8-cylinder compressors powered by separate 14.5-Lt Caterpiller natural gas engines. Check out these photos (sorry I know they are a bit blurry because of cheap cell phone camera).

Kevin, you sir are a cooling monster !!

[tool_462]

Should cool an FX-9590 for Pi 32M no problem!

[runmc]

That's too big for my room.

[tool_462]

What is it for anyway?

I might borrow one of those rads for a passive water loop too...

[Buckeye]

That's too big for my room.

I think I can fit in here (sure) but the power bill will be super high !!!

[Ivanlabrie]

Man, PLEASE, cool a cpu with that

Power bill? Nah, the gas bill!

Hey Kevin!
Great to see proper industrial stuff here! Whats the purpose for this unit? Seperating co2? Will it be a conventional cascade or will it be an autocascade ?
What typ of heat exchangers will you use, plates or tube bundles?
Keep us updated !

[Kevin Hotton]

It is a conventional cascade using Propene (R1270) in the warmer stage and Ethane (R170) in the colder stage. The system will be using a water-cooled condenser and has a design-point evaporator temperature of -65C. The cooling duty should be 190kW and will be cooling about a 50gpm flow of methanol used in a gas separation process that separates a mixture of hydrogen and carbon-dioxide into separated streams. It will use all plate-heat-exchangers (Large GEA units).

Kevin
PS: I am also working on a smaller air-cooled system (about 30kW duty also at -65C) which will be a two-stage cascade with the colder stage an autocascade. I will show some pictures of this when it is further along.

I Like the American Flag on the units. I was starting to think we quit making cool things in the States any more.
Nice Workmanship !!!!

if it is like here all the parts where made in china and just assembled here <_< We all need to take back our manufacturing and put it on home soil again, I am sick of aqll the low quality poorly made c*p out there now days!

My gues was wrong I was thinking of a NG seperation liquidizing system

[samsarulz]

Sorry to bother, but how does this project is advancing? I?m looking forward for some testing jajaja

[Kevin Hotton]

The MONSTER cascade is being delayed. The highest priority is now my somewhat smaller (but actually more exotic) fully air-cooled Cascade/AutoCascade hybrid. As I mentioned above It will have 30kW cooling duty at -65C. I can post pictures of this one in a few more weeks (constuction is only now beginning).

Wow! Just wow!!!!

Hi Xtreme'ers

These are a couple pictures of my cascade/autocascade hybrid. It has demonstrated good performance (25 kW duty at -80C). It use two 6-cylinder Copeland discus compressor of 128 m3/hr volumetric displacement each. The air-cooled condensers are on the roof the the trailer (they barely need to run in winter temperatures).

PS: I can't get jpegs to upload and attach so --> Learn more about our mobile system at:

That is xtreme, thanks for sharing.

Amazing idea and such an incredible system!
