    Hi,

    I recently bought a commercial open display fridge.

    I know nothing of its' history, but I think it's from around 1998.

    Can anyone advise me here? It's the IARP 180 Shelly.

    I just turned it on, and there's a lot of steam coming out the back of it. I'm sure it an evaporator- but it's running low and needs to be topped up soon.

    Also, there's temperature display doesn't seem to work. Do I need to push some buttons on it? It's all in Italian here it is-

    Check inside the fridge, there should be a tag riveted on the inside wall with the gas type, charge, serial # and date stamped on it.  Gas types change every few years, and a 15 yr old fridge will not run on R401 or whatever is available today.

    If gas leaks, it's because the system has leaks.  Most common place for leaks is in the coil.  You can get the coil repaired, but it's a lot of work and very expensive.

    Conclusion:

    Never buy used refrigeration unless you or your brother-in-law have a refrigeration repair ticket and access to specialized equipment.  Normal going rate for refrigeration guys is $70/hr, min of one hr,  plus truck fees, plus parts, plus taxes. Coil rebuild plus installation is $6-$700

    Cheers for the response.

    I didn't find the tag you mentioned, only lables I found were these:



    I knew it was a risk with this-but I'm trying to start a business and in no way can I afford this new ($7800 aud). So I bought this for $400 knowing I'd have to fix it up. At least the parts inside it will be new. That was my logic anyway

    Can anyone advise me about the evaporate reservoir (pictures in previous post). I want to test it out, but I'm not sure if I need to fill that 'pool' with water for it to evaporate?

    Oh geez, run, don't walk away from it.  It's running on R22 gas, which is virtually un-obtainable.  The older gas, R-12 is illegal.

    In the picture you see the refrigerant line coilled into a tub.  The line doesn't HAVE to be water cooled, that's the job for the compressor.  The tub (or tray) is there to catch all the condensate water and ice from the coil when it goes on de-frost cycle. The refrigerant line is there to evaporate this water, instead of having a drain line connected to the tub.

    If the water is actually boiling and producing steam, that means the compressor isn't working properly.  See, the basics of refrigeration is that compressed gas absorbs heat, it does this by getting un-compressed in the cabinet coil, and then recirculated to the compressor where it gets compressed.  While being compressed, it gives off heat.

    Or you can unplug it and use it for a dry-display case for cookies and the like..........

    Now I'm really worried! Is it fixable at all? Structurally it is fine.

    Can't I just replace all the 'internal' parts? Not wanting to run away from it...yet. I'd be happy spending upto $1500 (AUD) fixing it up.

    So the water is boiling-so I'm assuming the compressor therefore isn't working? Should I add more water to the evaporator 'tub' and wait to see if it all disappears?

    It uses R22 gas (which is being phased out in Australia)- I read you should not have to re-gas a fridge unless there's a leak.

    How can I tell if there's a leak?

    Also, would getting a new compressor mean I can use a different gas? Would it solve a lot of my problems?

    Thanks,

    Hi Quince...

    I guess you weren't "reading in between the lines".

    I guess anything is repairable---provided you throw sufficient money and time at it. 

    How much money do you want to spend?

    Where did you buy the fridge?  If it was through a dealer, get your money back, or get them to repair it.

    If you bought it at an auction or privately, you have to ask yourself this question:

    This is a valuable piece of equipment.  If it works when you bought it, it should have been running--filled with beverages or water bottles, to prove that it is running.  Whoever is was selling it, didn't do this.  Now you know why.

    Working with freon (refrigeration) gasses is not a no-brainer.  You need special equipment, you need the knowledge of how much gas to put in (ie the charge),you need to know how to test for leaks, you need the knowledge of working with pressurized systems.

    Call around to a few commercial refrigeration places and ask if they stock r-22 gas, ask them what their shop time is worth, and what they charge to come out on site.

    Never buy used refrigeration unless you have a refrigeration mechanic's ticket.................
