3/4HP Low Temp Horizontal Rotary

[kayl]

New compressor to try, 3/4HP horizontal Rotary, Low temp version.
Interesting to see how well it handles quad core

[Freddie123]

keep us in the loop, looks like it'll be an interesting build

Damn looks nice, great looking condensers too. Should perform wickedly.

where did you get it from?

Looks very awesome. What are the dimensions of this thing?

Question tho, whats that port on the bottom with a cap-tube and filter/dryer. Does that compressor use refrigerant-cooling for the windings or something?

[[XC] gomeler]

Oooohhhh... information? 4 ports? Err?

[Fhqwhgads6680]

whoa... that is unsual kayl... I don't understand how that would be very effiecient, I always thought rotaries performed best vertical... but that would make space managment interesting.

Looking forward to a unit with that in it!

Also, what is that at the base? the black box? and the what is that small filter and captube like setup in the pick.. .that looks really odd.. gll mate!

Thats called liquid injection, used to keep discharge temps down and cool the compressor, it will be designed to be 1/10 of the total system capacity and would use a timed valve to allow squirts in as needed.

or maybe oil return, with a oil filter, i havent ever seen liquid injection on anything that small, unless it's a low temp thing

Awesome compressor kayl - do some majic with it.

I was running your kayl evap at 250w today along with a nf11fx. The evap did great. I think the condenser wasn't keeping up though. It would hold the load at 38c for a about 45min then it would overheat the compressor and the bottom fell out. I think with a better condenser I would have been fine.

[Duh]

looks pretty nice
IIRC chilly and his partner ( D blasco) had FS some horizontal rotaries

[aussie_guy00000]

The capillary tube and filter on the bottom of the compressor is indeed for liquid injection to cool the compressor, It simply requires a 1/4" feed from the condenser discharge. Currently Kayl and I import these compressors into Australia, we only got a few to start off with so we can test their durability, performance and noise before importing larger quantities for use in SS and cascade systems as well as individual sale. But the horizontal configuration opens up a whole new world of possibilities, as the dimensions of the case can be kept similar to normal SS systems, but these compressors come in capacities from 0.75hp up to about 2hp, so multiple head units with high capacity are achievable. Now we only have to figure out how to fit big condensers in there too......

[Xeon th MG Pony]

Yes but from where! I'd be interested in them as a fridge compressors as for a comercial install it would be ideal.

That is pretty sweet. The power of a rotary in a small pkg.

[[486]]

no i meant if small low temp compressors have liquid injection, and i had it in ? form in my head, but couldnt you have like a small [2"widex4"tall] phase sep thingie that a 1/8" line would come from the oilsep, a 1/4 from the liquid line, have those two at the top, and the outlet to the bottom, and then shorten the cap tube in the compressor by an inch so you still get the same amount of refrigerant in the compressor, and simple oil return!! yay!

[n00b 0f l337]

Something like that could be possible, as if you run a cascade how would you work the liquid injection?

[Pete]

Can you do them in 240v at all?

Humm uber small cascade with 2 2HP's units!!! Plate HX, Ssliencer mount, Run MC evap, that be mental and what i want

[Duh]

but you wont be able to have it as you are getting moved :P
where are you moving to pete?

They are 240v, we're in Australia, everything is 240v here

Spoke to Kayl yesterday he told me it was needing a box around 600mm long.

The total unit length is around 590mm, not sure on compressor length.
Im measure the compressor later and update this post k.

i bough these off Aussieguy, but if they go well might import a few myself from china. I want to see how well they go first though and if like to run for several hours etc without overheating.

Thanxs runmc, im glad ya like my evap, was that the latest one, or the earlier model cant remember now, was that one of the evaps i sent in the past?
It seems condenser temps greatly effect load capabilities and temps. Keep that condenser cool and ya can hold a bigger load. Thats one of the things i have about Aussie summer weather and cased units. Once ya have a hot room temps, systems loose a little performance, get better results in winter.

I havnt been having much luck with these compressors.
First unit finished was this one, It ran and I applied 300w load and in about 20mins the compressor overheated and shut down. I managed to get it to start again but quickly stopped. Seems its stuffed damit.






Speaking with the supplier (from china) so English barrier a little hard, but they are telling there isn’t enough refrigerant in the system and that’s why the compressor overheated. Heres a pic of what these compressors are normally used in, cool room freezer.



Now im just testing a suction line on this smaller compressor seen here. Cpu is working fine, so ill install it on this compressor and see how I go.



heres the unit so far though

[Clemmaster]

Off course they won't run using them like that. You're lucky guys that rotaries do run in our working conditions without overheating... The air flow through the compressor must be even higher than what it used to run with.

where are you moving to pete?

Madrid was planned but things are all on hold due to problems with work and other things.

They are 240v, we're in Australia, everything is 240v here

Didn't know!

Kayl there amazing! The one with the dual condenser that an auto cascade?

Love the single conderser you got. Really want one!
