I hope I'm in the competition with this one.
AND IT WAS FREE



So I'm at a local restaurant over the weekend and notice their keg cooler had all the tap handles removed. After ordering a bottled beer the following conversation took place.

What's wrong with it?
It's not staying cold and there is a gap in the door.
Are you going to fix it?
No. We have a new one coming.
What are you doing with this one?
Take it out back and hope someone picks it up.
When are you getting the new one?
Monday.
I'll be there Monday evening to pick up the old one.

So we loaded it up last night and drove it to my house. I'm going to have to do some work on it. As you can imagine it needs lots of cleaning after being in service for 9 years.

The gap in the door can be fixed, I just need to rig the door back to normal. Not a big deal for an old sheetmetal mechanic.

I'll get it cleaned and running then I'll have a reefer buddy come over and make sure it is serviced properly and look for leaks.

This thing is so big I can fit 12 kegs in it!!

Dang Geoff, Be sure to let us know when it's up and running and we can come over and have a pint or two (or 12).

Wohoo.. that's some amazing piece of hardware... I'd had to get both a bigger car and a bigger apartment to even get that home home :-) Congrats Geoff!!

Yeah, I also have a cut on my finger if you would like to put some salt on that too.

Thanks guys, I knew you would enjoy this. It is going to take a little TLC , but nothing I can't handle.

The tap faucets are pretty old and dingy, but I'm gonna break it all down and give them a good soaking in OxyClean. There is a lot of hardware that has been replaced with steel and is now rusting or corroded, so I'm gonna have to change a bunch of that out with new SS. I'm going to fabricate a new door to cover the front of the compressor, and the diamond plating inside on the floor is a little corroded so I'll have to restore that too.

All in all not too much work. This is what I love about stainless steal, it can be re-worked and made beautiful again with little effort. The worst thing that can happen now is the refrigeration unit itself can go out or be bad. I think I can get a compressing unit and expansion unit for under $600. It is highly unlikely that it all has gone bad, so I should be in good shape for a little while.

Vance: I'll let you know when I get all 6 taps running and I'll send out an Atlanta APB for beverages at my house.

You didn't see Peter Roman hanging around the parking lot while you loading that bad boy. :-)_

Geoff,

Do you know which refrigerant it uses? It's old enough that it's probably R-12, which is no longer made, hence very expensive. If it's R-12 and flat, it would pay to just buy a new 134 condensing unit. If it's just low, and you have a bud that's an HVACR tech, you might get lucky.

He beat me too it...
My Free Crap Senses (in no way related to spider sense...or my irish drinking sense) were not on point monday.

One of the guys in our club has one that's very similar. A local bar was closing, and he asked what they were going to do with it. He didn't get it free, but $300 wasn't bad considering all it needed was a thorough cleaning.

I don't trust my reefer buddies to service anything properly...except certain types of paraphenalia.

Thanks for the input. Here is some follow-up info. It was manufactured by All Southern Fabricators in Clearwater,FL; the compressor is built for R-22 with a 32 oz. capacity.

I must preface this with explaining that I have a good background in refrigeration theory with little practical experience.

The manager at the restaurant told me that his reefer man told him that the evaprator coil was bad. He was told there was only one coil left in circulation to repair this unit. The manager made a decision to go with a new reliable machine instead of buying the last available replacement part.

This info does not jive with my A/C knowledge. If the system is not leaking then what could be wrong with the evaporator coil? There is no visual damage and the fans still work. I am guessing since the cooler wasn't staying cool he took a shotgun approach to troubleshooting and chose the evaporator coil, overlooking the fact that the door had a one inch gap on the bottom of it.

Since R-22 only costs about $3.50/lb I'll have my reefer buddy come over and evacuate and service the system so we can start to troubleshoot the system.

Guy C: I'll make sure he shows up before 4:20 so the two reefers don't conflict.

I could fit 6 to 8 depending on how big she...er...they are. It still doesn't cool so they will still stink after a day or two.

Hey, you're not a cop are ya?

Geoff,
It depends on what metering device is on the coil. If it has a TXV, it might have some blocked capillary tubes, which would mean that those circuits were doing nothing. The coil could have 6 or 8 circuits, for example. With 3 of 3 blocked, you can't get more than 50% capacity. If it has blocked tubes it might be simplest and cheapest to replace the evap coil, which still wouldn't be a big number.

Thanks Kent. It has a Ranco meter. It is currently set at 24 psi low and ~50 psi high. I'm not sure if the last setting is any correlation with its current condition, but I'm throwing it out just in case.

Geoff, the Ranco is the controller (pressure switch), not the metering device (or flow control). The Ranco switch turns the compressor on at ~50 psi and off at 24 (as presently set). The evap fan on a commercial cooler runs all the time. Air movind over the coil affects the refrigerant pressure. When the pressure rises to the cut-in setpoint, the Ranco closes contacts and start the compressor. The compressor pulls the suction pressure down, which in turns brings down the temp in the cabinet. When the pressure gets down to the cut-out the compressor stops.

What I was talking about was the device that actually controls the rate of flow of liquid refrigerant into the evap coil. It may well be a TXV, that is a Thermostatic Expansion Valve, or could just be a fixed orifice. Either way, it most likely has a distributor. The output from the distributor consists of several small copper tubes which connect to the evaporator. Some of those tubes could be blocked, and the rows of the evap coil connected to blocked tubes have no refrigeration effect.

BTW, if your system is charged with R-22, those switch settings are cut-in at 27 F and cut-out at 0 F. If it's R-12 it would be about 50 F and 25 F.

Woo Hoo! Nice timing Geoff.

I have a similar story. I noticed that they recenty removed a double door commercial fridge from the break room. A couple of days later I happen to be talking to our facilities guy and asked what he did with it. He said he was waiting to have it tossed out. I obviously offered to pick it up. I should have it next week. Double door, stainless steel. Woo hoo!
