Hi guys,

I'm from Murcia (Spain) . Thanks to welcome to me in your forum .

I'm making a phase-change system, wth your big info about them.

Which would you choose of these compressors?

They say that the Danfoss FR8.5CL is quiet , what do you think?

Thanks for your aid. A great greeting to all.

I feel much, my English is very very poor.

From what ive heard the danfoss is an excellent compressor and very quiet compared to others. The only downside is the price but if you have the funds i would go that way.

SC12CL
SC15CL
SC18CL
Any of these

SC12CL would make a nice single stage rig. :)

Thanks for your response .

¿ What is the more quiet : FR8.5CL , SC10CL or SC12CL ?


I want to cool the CPU with an evaporator of chilly1. it had thought about these components:

Evaporator: new Chilly1 evaporator .

Compresor: FR8.5CL , SC10CL or SC12CL ( The more quiet )

refrigerant : R404A

Condenser: the following one ( tube 5x4 for refrigerator 120mm ):

I will have sufficient with that condenser?

Capillary: 240cm (100") of 0.028"

filter: 15gr de silica

What dou you think about this ?

again thanks for everything. greetings.

I´m sorry, my english is very poor .

I wish I knew which was the quieter, but for the money the 8.5 is a good compressor. Rated for 404 and lbp, it's a nice unit, will give pretty much equal performance to the NL11 in the Mach2 units as it's more efficient and rated fro 404 instead of 134.

The condensor should be just fine. Rated wattage looks high enough and it's pretty compact. Would be nice to know the burst pressure, but it shouldn't be a problem on single stage anyway. :)

Bigger compressor is an option, but I don't think you really need it. I'm pretty sure all 3 of those are going to make close to the same amount of noise, and Danfoss is usually good for noise anyway.

SC series is loud . I have SC18CL and i can confirm this .
If you don't care losing some cooling capacity , pick the FR8.5CL . It's a very good compressor , and pretty quiet . I would say that comparing to the SC18CL , you will see approx. 10 degrees Celsius more . This is by comparing the PDF's from Danfoss website .

if the 10 degrees more brings 10dB down i'll pick the SC18CL.

but if you want a silent one k pick the other:D

If your buying a chilly1 evap..from chilly1..you may want to consider just getting him to go ahead and ship you one of his "embraco" compressors with it... I've built a unit using one of his Embraco compressors....its quiter then the 120mm 115v fan on my condenser. I can't even tell its on. And they hold load very well and would be a perfect fit for the condenser you have listed above.

If its any help, i run FR7.5G's using r134a and they are very quiet. Ive heard the SC series are loud, but perform excellently.

Gonna give it a shot with NF7CLX myself. Bigger version than vapochill's NF5.5CLX. Hope it is not as loud as vapochill one though... annoying noise on that one.

The FR8,5CL is loud in my opinion. The NL11f is much quiter and also stronger than the FR8,5CL (when charged wih R404a)

thank you very much for all your response.

I had thought about that from a first moment but, as you can observe in this image, only I can buy those:

I would choose NL11F over that poor VapoLS compressor(FR8.5CLX IIRC) anytime. From those options I would get SC12CL for single satges and SC18CL or SC21CL for Cascade use. They do make more noise than Prommy compressors but are still tolerable, and you pretty much cant beat the preformance of those :) I would even bet that the FR8.5CLX makes about the same ammount of noise than that SC12CL.

Thanks to answer hatemi :

Basically I have the doubt between those two compressors, is evident that the SC12CL is more powerful than the FR8.5CL but some say that series SC is very noisy more than the FR sure, each one have a sense of the noise. Of all ways, have I toput a in the condenser that has much of great volume? If it is therefore it gives me just as the compressor it makes noise more or less because the ventilator will even do more.

I am going to look for more information of these two compressors. Thanks for your aid companions. A great greeting.

I thought it was NF5.5CLX... I could be wrong though lol. And noise... yes... noisy... hate that bugger.

Thanks for your answer jinu117, but single I can decide on these compressors:

The only good options that I have, for Danfoss compressors, are the series FR and series SC. In particular, as you can see in previous post, the election was between the FR8.5CL and the SC12CL.

A greeting to all and thanks for everything.

Would go for SC12CL for more capacity personally. Took a look at SC10CL? might be quieter. Only reason I would be worried about capacity is the current crop of new CPU isn't really cool or cold when voltages are applied (even more so than before). My 1/2HP compressor is doing very nicely atm so I am guessing 1/3 to 1/2 hp one would suit future need better than 1/4 hp ones. I could be wrong though getting 1/4hp one to find out how it fares to 1/3 and 1/2 hp ones.

jinu117: We 230v/60HZ people over this side of the pond have different compressors in our Vapos and Prommys due to the difrent frequency of the mains. 10cc is the bare minimum I would use myself since I havent had that much luck with anything smaler than that.

Strange ...
A friend of mine changed the prommie compressor with an FR8.5 and got better temps. With the NL11 the system was extremely good tuned , but with the FR8.5 he didn't bothered to tune it so good. He measured about 3 degrees better temps with the FR8.5.
