Silent and strong chiller

Hello

It's strong and silent chiller. For me it's very hard to connect big cooling power and silent in chiller with one compressor. So I used two - Aspera NE2134GK, IMO those compressors are almost same silent as NL11F - each one work with one plate HX, plate HXes are connected in series.

2 compressors ...

2 condensers ...

2 plate HXes .... :D

Pressure gauges and controller is on top of case because owner want to have really low case, and also not too wide and long ..so that was really tricky to mount all inside it.


It works using very silent and quite strong fans - SilenX Ixtrema IXP-76-18, 16 fans were used.

Pump is also silent and enought strong Swiftech MCP-655.

With R507 unit was capable to hold 500W heatload in liquid with -22*C with very low sound level :).

compressor: 2x Aspera NE2134GK
heat exchanger: 2x plate HXes 20 plates
XV: 2x ALCO TI-HW
condensers: 2x 1.9kW each one with 4x SilenX Ixtrema IXP-76-18 153m3/h, 18dB
safety: 2x Danfoss Cut-offs
refrigerant : R507+R134a (mainly R134a)
case: black custom case
pump : Swiftech MCP-655 (Laing D5)
reservoir : Swiftech MC-RES Micro 2
others: electronic controller CAREL with touch buttons, REFCO pressure gauges, 6x SilenX Ixtrema IXP-76-18 153m3/h, 18dB in back of case .

That's loaded with 500W "tea" heater put in liquid. Carel's probe isn't put in liquid on that photo.
That was with pure R507.

But person who order it want only around 0*C loaded ...
So I fill it with R134a and it make +2*C with 500W load.

Pressures are quite low, even fully loaded.

Do You like it ? :rolleyes:

Peter

Wow thats one big mofo :D
really neat and tidy, great job.

Hey peter, how does the MCP655 deal with the los temps? no problems with the electric parts on the non insulated back? what kind of system will be used with this system?

Cheers.

That is a monster Chiller Peter :clap:
Very nice man, you do very nice work as usual :up:

thats just sick :D i like :)


great job ;)

Nice work Peter :)

The dual system is perfect for the high load, and around 0c with 500w is a great result for 134a. 2 smaller quiet compressors is a nice system working together.

Build quality looks great too. That case looks amazing :D

this is what I've been planning for the cascade staging too :) so it's cool to see it running in a similar format.

The incorporated pump is a nice touch :) I hear they work well even to fairly low temps, but if it's going to be a 0 to 20c range on it's setting to lower the condensation problems, then that pump should never have a problem at all :)

Truly a master builder, you've been doing this for a long time!

Hi

Thanks :)

That's 3rd chiller which I built with MCP-655 and I haven't got any report about bad work of that pump in previous chillers even after long time of use ...so I guess they work very well in chillers :yepp:.

I've tested them up to -30C liquid and they still work :rofl: :up:.

Thanks You all for very nice comments :up::up: .

Peter

how much power does it take to hold those loads?

thats is a big monster chiller.
Another ¨piece of art.:clap:¨

2:up:!!
