This is just a bonus, video there's not enough video footage here to make it a full length video, but i'm working at a custom, stainless steel fabrication shop and i'm putting all the refrigeration equipment into a refrigerator that they're making for someone. Okay, just some context here, the refrigerator is not finished whatsoever. The the fabrication shop is gon na cover everything make everything you know uh fully up to code and everything, but you guys are gon na see the rough uh installation of the refrigeration equipment and our crude way of verifying that the unit works and stuff. So we'll talk at the end of the video, this video is brought to you by sportlin quality, integrity and tradition.

All right, i just got done wrapping up a custom installation, so this is a custom box that a stainless steel fabrication shop is making forgive the noise because there's a giant laser next to me being ran. So what they do is they build these boxes and then they ask me to load them with refrigeration equipment. Now what they'll usually do before they build the box? They'll go ahead and consult with me and we'll decide. You know what size coils and everything like that.

Essentially, on this box right here we put a 1700 btu evaporative coil. Certainly the space inside here is not big enough for 1700 btus, but when it comes to reaching coolers you're actually more concerned about airflow, we need that airflow to get over into this section over. In here that's why we have the diverter up in there, but we tend to oversize the evaporator coils, just because we need the airflow to move around the box. Now this particular box is going to be a training box, but that's doesn't really matter um.

So the standard operation on this thing, so they kind of you, know, give me an idea of how they want it to work and then i kind of change things as i'm going, but they have two power switches. Now you see one says coil one says: heat blanket well: they're still gon na fabricate a bunch of stuff heat, lamps and stuff like that up there, so i'm just wired into the coil, so my coil gets turned off by this switch. There's a liquid line. Solenoid valve inside there and i'll take the coil apart in a minute and show you guys, but we have a temperature controller mounted right here with the sensors and everything all ran over there up into there inside the box, the temperature sensors back down in there.

You can see the drain line running over there they're going to clean a few things up. They'll, you know scrub the inside of the box and all that stuff, but um condensing unit. You know set up right here. I have them fabricate these little s, channel brackets.

So that way, it holds the condensing unit in place. I'll, take you around the back side now now, because this box is still in production, the electrical is really rough. The customer themselves have a lot of stuff that they're going to mount inside of here for lights and heat, blankets and different things like that. So they'll still finish this up, and i just do you know.

Basically, my connections um and i tape up what i don't want them to undo when they hook up the electrical. So then i leave these ones loose so when they hook up main power, they'll hook it up to these guys and leave my stuff alone. I've also got a junction box way back up into there. The condensing unit and the condensate drain.

Pan heater is ran off of this receptacle, so it can be unplugged. Now, we've done a few of these boxes and each time we change a few things with them. The next time, because we're kind of out of time on this one, the next time they're going to fabricate me, a little stainless steel loop right here - that's going to hold this drain line in there um we had to go with uh a taller bracket, because these Brackets right here get really hot just because they touch the the drain pan and over time. They'll start melting this.

So this one right here is actually a quarter inch above, so it's not touching any of the drain. Pan we've got refrigeration lines right here, we'll probably come up with something to hold those in place. We also have one of those s channels back here to hold the condensing unit, so you know they can ship this box, move it in and out of a diesel truck and stuff like that and they're not going to have to worry about anything. I also made enough of a refrigeration loop that you can slide, in fact the entire condensing unit.

Earlier i had it out while it was still piped in and on top of that box sitting right here, so we have enough of a refrigeration loop that a service technician can come in here and work on this thing and not have to worry about it. The unit uh has a receiver. We have a txv inside sight, glass right here. This is just a pre-built condensing unit.

You know, i certainly didn't pick it, but um we have pressure controls, we have a high pressure and a low pressure right here ran in series. So that way they run through each other yeah and that's pretty much it. So this is just uh again, it's still rough because they still got to clean a lot of things and polish it up and make it look pretty. But this is a basic uh custom box that we do i'll open up this evaporator coil, because uh i've got the system running right.

Now, i'm actually about to cardboard everything off. So we can see it come down to temp, but i want to do a leak check first, so we're going to start it up and i'll show you guys the inside of the evaporator, even though i know my braze joints are good and even though the pressure Test passed and the vacuum was good. I'm still going to do a refrigeration leak check because this box, i don't even know where it's going it might be, leaving the state for all. I know so.

I'm just leak checking all the braze joints that i did and i tried to keep my brace joints to a minimum. I already checked underneath this insulation, so i made a one piece loop. So there's a brace joint right here, there's a brace joint right here and then it's a solid line set all the way to right there. These two braze joints right here.

So then you don't have to worry about. You know refrigerant leaks anywhere else, um the coil is nice and compact. I like these uh remk coils because they have so much space inside there, but you can see we got the sensing bulb insulated, txv's, accessible uh. You have to kind of make a decision.

Do you want the power head accessible or the adjustment stem accessible? The power head can still be replaced where it is, there's still room back behind there, but you see the temperature sensor down there, but yeah we're all good we're gon na go ahead and cardboard. This off and watch this thing come down to temp, just a temporary solution. Taped everything up box temp is at 38 degrees. It's about ready to satisfy, so all is looking well.

I usually tell the customer to leave it plugged in overnight and as long as it's down to temp, it's got the green light in the morning. So i just thought that was an interesting video i'd put up i've. I've do all kinds of work over the years for this custom shop, um and i've actually done this identical box a few times, but each time we do the box, we change a few things. We make it better.

We improve upon things, we add new electrical boxes, trying to make it more. You know uh, seamless or fluid or whatever you want to call it, but it's just interesting. It's kind of fun to be able to turn off the crazy of normal service calls and stuff and go work at a facility where i can actually drive my van up. I i couldn't show too much in the video, but there was a giant bay door and my van was parked right there.

So you know i could leave my van unlocked the doors open the entire day and a half that i was there um. You know go back and forth and it's also interesting too doing this kind of work, because it's not like you go there and you get it done in 10 minutes like you know, i go there with a box, that's halfway completed. So as i'm working i'm having the fabrication shop, make things you know, and then i have to wait for them to make something. I go do lunch, i go run to a supply house while they fabricate different things for me, different brackets and new drain pans like, for instance, this one, the drain pan um on those standard heat craft coils.

The drain pan came out the bottom. Well, that wasn't going to work with the setup that we had, so i had them custom fabricate a drain pan where it came out the side and hence why, if you go back in the video you guys will see that the drain pan is coming out. The side now so it's kind of cool, because you're not constricted so much by the design of the evaporative quilt. You know i can actually have them almost fabricate anything that i need so and then you know we learn from these jobs too, because each one it's like hey.

You know that drain pan it sits a little too high, so they're gon na try to drop it down as low as possible on the next one that we do, which will probably be in another six to eight months. You know so each time is an evolution and we, you know kind of change things and try to make the box better and better um. You know the the condensing unit. We bought a pre-packaged condensing unit that already had the sight, glass and dryer installed.

You know not my favorite, but you know we we put that in there and and like the temperature controller, i usually don't use the johnson pen temperature controllers and there's nothing against them. I'm just more of a ke2 fan the ke2 therm ones, but um the particular customer that this is going to uses those johnson pen, a419 controls all the time. So it's like, i thought it fitting to go ahead and put in what they use all the time, because that's what their technicians are comfortable with you know, and then you get to put some thought into making these. So could you imagine every single refrigerator for those of you that do restaurant work right? I'm sure you guys have all worked on a refrigerator and been so pissed off, because the way it was designed right.

So it's really cool to be the guy. That's designing it! You know to have a say in the design, because then it's like hey, i'm going to make a one-piece line, set where there's no braised joint in between and hey i'm going to make a refrigeration service loop. That's long enough that i can pull the entire condensing unit out to clean it. Like that's cool, for me, to be able to do that.

You know i get to address the things that i want to do and it's neat too, because you know i don't have to be so crazy with, like the the electrical cord, that's running from the temperature controller to the to the evaporator coil, because the customer is Going to custom fabricate pieces to cover that up to make it look perfect, you know, so it's really neat to have to or to be able to be part of projects like this, and i've certainly done some other really cool stuff at this shop, but unfortunately there's Some things because of you know, um just the sensitive nature of where the boxes are going, and you know what client they're going to you got to be careful. What you film on this stuff too, because you can mess with some people's privacy stuff and i'd really like to take you guys on a tour of their their stainless steel shop, because it's it's ridiculously awesome. They have two giant lasers that they basically have guys sitting at computers all day long just coming up with these designs and the things they can cut out with these giant lasers is so awesome. It's so neat to be able to see what they can do and it's really interesting also because i've grown up working at the shop since before i was even officially an hvac tech.

I remember going to the shop with my dad, so i've seen them evolve from a shop that just had you know: 20 people to 30 people to 60 people to 90 people. You know whatever and you know, they've expanded the shop and it's it's really cool to be a part of that kind of stuff, and it's really neat so anyways. I just thought: i'd bring you guys along on this one, just something neat um, we'll have a normal video uh. You know on the normal schedule and stuff.

So this is just a bonus one, but hey really appreciate you guys and we will catch you on the next one. Okay.
