So they called because the beer was too warm, this video was actually filmed a while back and since this actual repair was filmed I finally convinced them to replace both of these glycol units.

This video is brought to you by Sporland. Quality, integrity and tradition. All right. This morning we have a call on the beer pouring warm.
so the first thing I do is come into the Beer Walk and it's down to temperature in here. No problems. Um, so we're gonna get up to the glycol unit and check to see what's going on with the glycol unit. That's probably where our problem lies.
Guess what? I'm back. I've done a lot of work on these units. This is one of my favorite ones because it has its own mini split up here. But uh yeah, it looks like that glycol unit has a problem because it should be maintaining about 26 to 28 degrees glycol temp and we're high and then that bottom pump is at 46.
So I bet you got a bad pump. All right. So we come up to this guy and uh, this pump's not running and you can clearly see maybe I lost a bearing because that looks like bearing dust. Uh, these pumps don't last very long.
They're under a lot of abuse. This one looks like I installed at 9 14, 20. So it's over a year old so probably gonna need to put a new pump on here, but we need to verify that's all that's wrong. We need to make sure it's getting the right voltage and everything and at the same time we don't just ignore that one would come over here I Don't know.
this one's kind of high too. 36 degrees huh? running. Running? We're running, but it's a bit. High What's the set point at 31-0 That's not too bad, but I'd like to see higher than 36.
or lower than 36. But all right. Well we're going to go over to this guy because this guy I think is where our problem is. So for those that are wondering that are new, these are glycol units.
They're tiny chillers and what they do is they circulate cold antifreeze. but this is food grade glycol. It's propylene glycol. it's in a reservoir up here.
this is an older unit. newer units are a little bit more efficient, but this one has a reservoir and then they have a that bath of solution is refrigerated and dropped down usually around 26 to 28 degrees and it's circulated via these pumps and what it does, pumps it up and it catches the beer lines. The beer lines coming out of the Beer Walk and the beer walk-in has uh maintaining. you know, 37 38 degrees.
but the beer taps are a good couple hundred feet away from the beer walking and in this case the lines. I Think some of the lines run underground I think some of them run above ground and these glycol lines keep the beer cold from point A to the Taps. So from the beer walk into the Taps it keeps them nice and cold. So that way you get nice cold beer clearly hear the pump.
it's turning on and off on overload. It's it's locked up so we still got a check voltage though to make sure it's red hot. the other one's running. It's hot too, but it's running so so you always want to double check.
I Pulled the the pump assembly off of the motor and then when I try to spin it I Don't know if you guys can hear that, but it clearly has bad bearings. Sounds completely metallic and it's got rough spots there. It's trying right now. so um, yeah, this guy's dead. So I'm gonna go get a new pump and motor. We've changed the assembly together. Get some insulation tape, the other one's working. I'm going to turn the unit back on and let the other side run.
You may remember if you guys remember me working on this unit about a year ago or something like that, they had a bunch of burnt up electrical in there. It's a good sign, there's nothing burnt in there. Everything looks okay. I Put a new controller on it a while back and then we put all new switches and thermometers and everything looking good.
so it's just a matter of unbolting the the pump. Usually what you can do is just take it out of the Cradle leave the Cradle bolted on. Um, as long as everything fits, we'll do that. and uh, we just gotta undo this electrical connector down at the bottom for the MX connector right here and we can just pull it out, wire it in, put the new one on.
that's where we're at. Uh I brought a pump, uh, bucket. always bring a bucket up and towels and everything because these things usually make a mess when you have to undo the glycol, lines and stuff. All right.
So what I did was I disconnected all the wires to that connector right there and undid it so I could just pull the whole thing out and then that way I can just you know, do my swap outside make my life easy instead of trying to fight it over there as I'm going through here I'm taking pictures of everything too. even though I know how to wire this up, it just makes my life easier. You know when it's like oh, I really don't want to think much just wired up the way that it was? you know? um, but yeah, this shouldn't be too difficult, should be good. All right.
I'm at the point right now where I'm changing the pump and I've got glycol flowing out so I'm able to use the bucket I cleaned it out as best as possible to catch the remaining glycol. so I don't have to waste it and now I'm going to switch out the other side and keep going with this guy. All right. First and foremost, we got 120 volts going to it I've got this guy connected I don't insulate it until I turn it on and make sure I don't have any leaks.
We'll turn this guy on real quick. kind of sketch. We're allowed to run 6.1 amps and we're right there. Let's give it a little bit.
Yeah, we're right there. right on point. so we're gonna let it run for a few minutes. Make sure there's no, uh, no issues, but we know we have the right voltage going to it.
Um yeah, we're gonna let it run for a bit. All right, we are back up and running and we just got to give it some time. Um I'm looking at the sight glass. you guys can't see it but it's right there and it's clear.
So I don't see a need to put on service gauges. The condenser is clean, the filter is clean, so we're good on that. It's just, uh, hurry up and wait. Now we're gonna watch this thing come down and tent. make sure everything else works on it. All right. Everything is looking good. Um, pumps are running.
Life is good on those temperatures drop significantly, it's still not low enough. Uh, our set point is 31. So it looks like the beverage company got in here and upped the set points on these because normally I see them 26 to 28. but I'm going to leave them where they have them because they're The Magicians when it comes to the the beer stuff, I'm just here to just you know, knuckle bust the pumps and motors in.
Um, but yeah, we're looking good. So uh I'm gonna tell him to keep an eye on it. Um, fluid's moving like it should be I put the fluid back in it. Oh yeah, we're flowing nice and good.
Everything's looking great so we are going to, uh, give them the keys. This particular video actually has been sitting in my archives it was from it was completed in 2021 so it's obviously a couple years old but still relevant information. It's funny when I watch these videos too because as I'm going through things I'm like would I have done things differently now now that it's been two years since this video was filmed or or a year and a half or whatever it is. No, it's it's really cool, you know.
recently I went back to my channel and I watched the very first video on my channel thinking like how is my service diagnosing has like how has it changed you know, pretty much the same I watched my first video which was me diagnosing a beer walking that had a blown fuse and I'm like as I'm watching it it's funny because my wife was sitting next to me I was like this that was like five years ago and I I would diagnose this The Identical same way my verbiage would probably be the exact same. It's kind of kind of funny how that stuff works, but uh, this was just a bad pump. Okay, these little glycol units or glycol chillers, whatever you want to call them beer coolers? Beer: Chillers Um, there's really not a whole lot to them, you know, just a refrigeration section and a secondary fluid. a glycol or antifreeze, whatever you want to call it.
and it's just pumped through the lines. The whole point though, kind of I I Said it in the video a little bit. but the whole point is is that you've got beer in the beer walking. but you've got to run those lines.
Uh, in this situation, they go underground into the bar and then that's where you know they can gain the temperature from underground, right? because there's a lot of heat content in the ground. and so as those lines run through a Chase they're obviously absorbing the Heat and it can bring the beer lines up. And so you end up with a lot of wasted beer. Because if you know the beer lines get above 40 degrees, you'll start to get foaming as the beer is coming out of the Taps and then the foam equals wasted beer. So they try to keep them cold from point A to point B The beer lines themselves are usually the the fluid that's circulating in there is usually I'd say about 10 degrees colder than the medium that they're trying to keep cool. So the beer that way they can actually have heat transfer and they just wrap around and are super insulated in the beer line. So there's usually only two glycol lines or maybe four glycol lines in an entire uh, trunk line of beer lines that's running underground or up in the attic, whatever it may be. So they're really not too complicated.
they can just be. It can be a little difficult to diagnose like problems with pumps and different things like that. Where it can get kind of tricky is if you have a pump that's not operating efficiently. Another thing to differentiate or explain is that we will often refer to it as a pump when we're talking about the whole assembly.
In this situation. you know in the beginning I said we had a bad pump, but in actuality the motor had bad bearings. But what can cause the motors typically to go bad is the pumps going bad. The glycol in the system actually needs to be changed regularly.
The glycol can pick up a lot of contaminants and especially if it's not maintained properly and stuff so there can be contaminants in there and those pumps can get gummed up with Gunk and it gets kind of hard to turn the actual brass pump itself and then that's usually what ruins the motors and what damages the bearings and the motors. To be honest with you, majority of the failures that we see on these is that the little um piece that comes out of the pump that's connected to the impeller. Basically that will usually get rounded out. you know where it goes into the motor connection.
and so anyways, they're really, really not that difficult. It's just the basic fundamentals that we learned. You know about refrigeration and air conditioning. You've got a refrigeration system and you have a motor that's circulating a cooling fluid, right? a glycol and that's it.

What a nutball setup Are you in Barrhaven ?
Hey Chris, been watching your videos for a while. You know your stuff and down to earth. Just a friendly reminder to back up your videos. Ideally at least two local copies and one copy online. Keep up the good work.
had a motor smoking one day at mcdonalds multiplex macine
Are there pizza plugs on the glycol lines some where, like with chillers?
I am not a fan of procon pumps. Have you ever found something else? Those banner units run and run otherwise.
its crazy i remember these units. i watch this channel alot then!
Thanks Chris. Your videos have been most helpful in making me a better, diversified tech!
I do remember this place and those units! Fun to see revisits.
Hey Chris I’m sure you’ve been asked by why don’t those chillers use dyed glycol instead of clear? Doesn’t that make it challenging in the event of a leak? Or is that beverage company?
Pump was ok motor burnt out Chris 🤣👍
I want to buy one of these to cool a PC
I wonder how the compressor would handle the constant heat load
I dont see beer lines putting out a constant 500W heat load lol
Im pretty sure i watched a video where you replaced some stuff on these pumps before lol EDIT: Got further into vid and you said it was in a previous video lol.
Fascinating video yet again. I don't know the first thing abot what you do; but I enjoy watching someone that "knows what they're doing". 🙂
Thanks for the video, I would like you make more of this videos about glicol sistem.blessings Are you in Orleans ?
Hey Chris, Chris open the pod bay doors, Chris open the pod bay doors, Chris open the pod bay doors.
Does the min split make the glycol unit work better as the room wont get really warm the place i worked at had a glycol unit about the size of 3 of these units and the heat was unbearable in the room and the drinks were always too warm they never got a repair even with annual checks from the drinks company Are you in Kanata ?
cool i remember watching the video where you installed the motors in 2020. And i learned what a glycol cooler was 🙂
You can get nylon pump saver bushings and it just interfaces between the pump and the motor. The bushing will eventually fail from being rounded out but it doesn't seem like it fails before the motor does. Assuming the pump is fine the bushing just gets replaced with the motor.
Great video Chris. If I could make one suggestion when it comes to checking motors. I had an instructor tell me this years ago. When you want to check a motor to see if it's hot, use the back of your hand not the inside of your hand. In the event you have a wire touching the motor by using the back of your hand if you get shocked, you can easily pull your hand away. If you use the inside part of your hand your hand will contract and you will not be able to let go of the motor. Thank you for sharing this video.
You are a hero and a good man…
thanks for the great video! Hope you feel better!
I'm surprised the glycol unit makers aren't using something like a peristaltic pump for the glycol lines- no impellers to damage, less corrosion risk
Do you work on “Banner” glycol chillers ?
I am curious as to if you would’ve found a higher grade/premium motor would that of extend the life of the motor over a year or two at least? Service area Barrhaven??
Damm whatta hell them pumps lasted you one or two years??
I have a set of little glycol gremlins aswell in the hotel i try to maintain. Them motors are little troopers been going for years
didnt know they go out in less than 2 years though
Good one.
So… when you notice a major ( motor ) or minor ( contactor ) part not last anywhere near as long as it should, what can be done ? There must be a better strategy then just putting the same intentionally cheap part that will fail again and again. This is clearly not sustainable in anyway for anyone.
I get a calming feeling by watching your podcast.
The glycol pump motors always seem to run like garbage. Extremely hot, right at the RLA, I just don’t see how they’re supposed to run like that
Chris – Is that a drip next to the temp readouts?? Are you in Ottawa ?
Why wouldn't the motor kick off when it is overloaded by a dirty pump? Any motor that wears out that quickly is garbage. There are industrial pump/motors under much worse conditions that last much longer. I'm not questioning you, but the quality of the parts we get today. Do the pumps come from China?
Thanks for another great video!
Great Video. Thank you for sharing
I've seen the beer guys up the setpoint to avoid icing up the evap, but it's due to the incorrect ratio of glycol per water, freeze protection to too high of a temp.
650 Thumbs uP
This system is two part? Refrigerant condenser and evaporator cool the box and these glycol pumps circulate through/near evaporator than next to beer tap lines to keep them up to temp at the dispensing station? Service area Ottawa??
Great job Chris big picture diagnosis Service area Nepean??
Chris, you need to update your meme with more hair and a beard!!! 🤣🤣😂😂
It's 9 am right now in texas, I'm really wanting a nice frosty tap beer now.
Hello!! What it’s normal temperature in the walk-in beer cooler?? Thank you!
It appears that there is a fair amount of fluid leaking from under the elec panel at the end of this repair.. I assume that some glycol was spilt onto the unit during repair.. but would be worth checking out when you next get to site.
You’d think a good quality motor would last longer than a year….
I know you guys are the pros but, shouldn't that temp be lower Chris? Service area Kanata??
I still have my refractometer for testing glycol. Back in Buffalo, most systems run with glycol and you learn how to work with it, and what problems happen by using it. Here in Austin…..haven't seen one glycol system yet. Glycol can degrade over time ( even with the inhibitors thats put in ) and they can play havoc with pumps and motors. Its due to the specific gravity and the viscosity. Most general duty pumps aren't built for glycol. Water has a specific gravity of 1…..glycol is above 1 and the higher the mixture…the more that changes. It puts added wear and tear on pumps and motors. Service area Orleans??
Not a drinker but I would be disappointed if there was Miller running through those lines. Warm piss cold piss probably no difference and no one would notice.
<3
💪👍❄🇺🇸 nice work. Glycol units can b a PITA especially wer they get installed. When I replace the procon pump I'll clamp the Glycol hoses to avoid loss of Glycol. N good move replace whole assembly. 👍
7 minutes of video and 6 minutes of commentary? Come on man you can do better than that. You didn't even show the repair that you made. That's why I'm watching Are you in Nepean ?
If you ever start a buisness channel that explains how to run a buisness and how you get your numbers, pricing and break downs let me know. Ide pay a monthly fee to learn that side of things as well.
Great video as always.
As a UK real (cask) ale drinking chap, beer to me is a 'live' product, that you know will be at its best when hand pumped out the barrel at the bar, or just from opening the tap direct from the barrel. Kept just a bit below room temp (ie the natural cellar temp). No gases, no long pipe runs, no 'freezing delivery'. Bring on the Porters, Stouts and Milds. I'll buy Chris a pint when he comes over!
Wished you had filmed detaching and reattaching pump from motor. Are both coolers on one glycol circuit?
I was missing a glycol video. Had been a bit 😀
We have similar pumps/motors on our fountains, lately they’ve been shipping a newer style that has a big magnet that sits on the end of the motor and turns the pump, so there is no direct drive there and no seal/interface between the pump and motor to wear out. They do seem to last longer but they are definitely louder than the old style.
❤️
Don't that glycol run through a water chiller with an ice bank in that system.
Warm beer is an emergency call for sure
That minisplit is just stupid, cooling refrigeration equipment with refrigeration equipment. Who brings the post to the postman?
But hey, it is what it is. Either spend 1000$ once to put the glycol units where they can actually breathe or spend 500$ on electricity every year for the needed minisplit. And the customer sees: 500$ is more less money than 1000$ duh!!11
And the European solution: Produce Beer that actually tastes good, even above freezing
Hi Chris, why instead of having a separate cooling unit, is the glycol container just being placed in the main beer cooling room ?
