    Just checked Hychill for the R290 8kg bottle I assume that's the right one. Looks like it might be interesting to run some in a Vapochill and see what it can do. You tried any on a Vapo as yet C-Buzz?

    yeah, stock standard run of the mill R290 from my local petrol station :)

    havent tried it on a stock vapo yet. Tried it in my modified vapo was getting -35/-40 idle before realised that the evap was leaking heavily.

    havent got anything here to test them loaded with at the moment so not to sure how it would run.

    Hmmm might fill the little Vapo up with this stuff and run it on the die simulator. That will see how it performs. The R290 is very similar to propane from what I can see of its formulation. Is that correct?

    Ok, the MOSFET Fan Controller works a treat.. :thumbup:
    I have not done the RPM output line/VCO yet..
    Dont know if I'll use a 555 or just a tank + tran'y, tank will be quicker..

    Cheerz..

    how much it set you back? Does it allow you to have full controll over the fan?

    Dont know the price, I just grabbed the parts from my junk box.. At a guess, prolly $2~$4 for the MOSFET, under $10 for the whole thing.

    Control, set it up the way u want it dude. U can have it low where the fan does not spin - or high where the fan run peak 99% of the time..

    The only thing I dont like is that it isolates the GND of the fan, and could make it a real pain to get an RPM pulse from it..

    I have it driving my four 120mm vantecs, its been up for about 15hours straight now.

    Cheerz..

    did you checka the price $5xx i wouldnt wast the money its not much better than bbq r290.
    better going for some r402a if you can get it java

    propane is 290 in refrigerant terms they call it r-290
    i guess r is for refrigerant maybe


    i think the r290 would work well in a vapour LS, could put extra amount of refrigerant compared to say r404a and the high side pressire wont be too high.

    hey cbuzz when beetroot said before 100psig high side doens sound sort of low. must be because of the level of vauum ya running there.
    should be around 150-170psig at load.

    yeah I thought it might be a bit low.. as i've got a few smaller one's here ive done which sit on 170+psig.. however they dont run in vacuume so i'd say that's why.

    if I pump it to 120psig the temp rises quickly & frosts all the way into the compressor.. so I think around 100psig is the sweet spot for her unloaded.

    Made this little system the other week, had problems with a leaky evap so it just sat there.. so I decided to pull her out & fix the evap.

    Compressor, out of small bar fridge, very nice & quiet.

    Not very happy with the temps, suspect there is a blockage somewhere... think I adjusted the cap tube to many times :/

    Thanks

    Im on a bit of a modding spree at the moment :/

    I acquired this Vapo PE of an OCAU member a while back, they told me compressor was dead & it was leaking & aparantely had a clogged evap, so its been sitting there for 4 months..

    I was boored again so I decided to check it out to see if anything could be done..

    It became very apparent someone had tried to modify it & totally botched it up..

    I didnt take any pics of the before shot as they are just not worthy of showing lol...

    here is the base unit after I cut the suction/evap & drier off

    The botchy brazing job on the suction line (looks a bit like mine a not long ago lol)

    A quick check to see if the compressor was still working. After I turned the power on I couldnt hear anything, I initally thought it was dead.. until I put my ear close to it to hear a very soft hmmmmm, dam these things are quiet. So the BD50 compressor is good after-all.

    Carrying on :)

    The clogged evap with a copper suction accumulator! Bonus!...

    Put an access valve on the end.. give it 150psig worth of bottle pressure to clean it out... should do the trick :)

    Connect it straight up to the bottle :), slowly cranked up the pressure, then pssssss!! success!

    Then to braze it back onto the compressor, I decided to have the evap facing upwards, I know the BD35 compressors cant really handle upwards pressure, as there just to weak, but I think the BD50 should be able to handle a little. So I brazed the evap on sideways so it can be mounted at the bottom of the case instead of the top.. anyway one way to find out! Looks a bit like an exaust or somthing :thumbup:

    I actually got this unit up & running today & was holding at -30c with 30c ambient which is pretty good....

    Get some pics up soonish :)

    Thanks

    Vapo mod # 2

    Time for an uptdate :)

    I recently acquired Grooveteks Dead Vapo classic, so I thought i'd have a play around with it..

    Stipped the unit to just the bare condensor, had an old mini fridge with a nice Danfoss Compressor 102U/2032. Either 1/5 or 1/4hp. Couldnt find any specs anywhere. Had to completely re-wire it as the old wiring was boorked & it was smoking heh.

    After removing the old BD35 compressor the new compressor slotted straight in & fitted like a glove!

    Brazed it all together, robbed an evap off an older project & did a little insulating, here she is ready for action!

    Decided to hook the Vapo controller up just for the hell of it. Its about 5c out of whack.

    Lowest temp I saw for the day was -37 unloaded. Wasent really expecting extreme low temps, it should have a lot more cooling capacity compared with the SE.


    Really need to get myself a load tester :/

    Total build time, not incluidng the evap was around 3 hrs. Takes about 2hrs to make 1 evap :/ cut/drill/braze ect..

    looks good, cbuzz i have found dummy loads are quiet hot compared to the real thing, and for best temps best to tune on pc.
    Have you had any luck finding flexable suction line yet.

    havent even got a decent enough system to test it on :( no luck on the flexi hose as yet.. still looking for a cheap source.

    i've been fantisizing about a controller for one of my units, got a small lcd touchscreen lined up...
