00:00:00,000 --> 00:00:08,000
Six months ago, I got a steal of a deal on this Environtronics thermal testing

2
00:00:05,800 --> 00:00:11,920
chamber. Brand new, these puppies can go for tens, if not hundreds of thousands

3
00:00:10,680 --> 00:00:19,960
of dollars. How much did I pay? Less than 1,300

4
00:00:16,320 --> 00:00:22,640
US dollars, and that included Delicia.

5
00:00:19,960 --> 00:00:27,040
I'm sorry, I mean delivery. Back when we unboxed it, we were blown away by how

6
00:00:24,880 --> 00:00:31,520
good the condition of it was. I mean, sure, it was decommissioned over 10

7
00:00:29,120 --> 00:00:36,520
years ago and left outside, but there was next to no corrosion, and it even

8
00:00:33,960 --> 00:00:39,080
had full documentation, service history, and schematics in the box.

9
00:00:38,645 --> 00:00:46,960
>> [music] >> I mean, how much more could it cost to integrate into our testing lab?

10
00:00:44,360 --> 00:00:51,320
A quarter million dollars? The good news is we got in touch with the guys who

11
00:00:48,600 --> 00:00:56,280
decommissioned this exact unit, and they got it in working for less than a tenth

12
00:00:54,560 --> 00:00:59,240
of that. Oh, well, that's wonder Wait, what does it working mean?

13
00:01:00,720 --> 00:01:06,480
What does working mean? For you? It means that we're going to tell these

18
00:01:31,600 --> 00:01:38,960
Before we get into why it's only working today and would cost us over 250,000

19
00:01:37,360 --> 00:01:42,360
dollars to permanently install in our warehouse, let's take a look at the

20
00:01:40,800 --> 00:01:48,000
progress that we've made on the unit. I mean, I can already see that a lot has

21
00:01:45,240 --> 00:01:51,040
changed here. And to get the details, it'd probably be best to talk to one of

22
00:01:49,600 --> 00:01:55,080
the technicians who's been here grinding away at this particular achievement over

23
00:01:53,160 --> 00:01:58,760
the last few weeks. First things first, Stephen, can you talk me through why you

24
00:01:57,320 --> 00:02:03,200
guys needed to bolt this sheet of plywood onto the side of the unit? So,

25
00:02:01,120 --> 00:02:06,680
basically, what we ended up doing is creating a whole pump system for this

26
00:02:04,960 --> 00:02:12,000
unit because it's water-cooled. It's not air-cooled, so normally this unit has a

27
00:02:09,600 --> 00:02:17,760
much bigger condenser or cooling unit up on a roof or a cooling loop in a

28
00:02:14,200 --> 00:02:19,600
building, but we had to make it work.

29
00:02:17,760 --> 00:02:23,320
One of our ideas to dissipate the heat from the unit was to use these scrap

30
00:02:21,520 --> 00:02:28,480
cooling towers that we dumpster dive, but unfortunately, it just plain wasn't

31
00:02:26,280 --> 00:02:32,760
enough capacity. So, why don't you walk us through what we're Oh, lordy,

32
00:02:30,640 --> 00:02:36,280
actually doing? We're using your water connection to cool the unit. So, we're

33
00:02:34,560 --> 00:02:41,040
just running cold tap water through it and then dumping it once it's heated up.

34
00:02:38,520 --> 00:02:45,720
Okay, City of Surrey, if you're watching this, this is temporary, okay? Just like

35
00:02:43,840 --> 00:02:50,160
to do this video, and like there was a heavy rainfall atmospheric river like a

36
00:02:48,040 --> 00:02:55,920
week ago. This is not permanent. Please don't be mad. To be clear then, we're

37
00:02:52,240 --> 00:02:55,920
not using this at all. No, we aren't.

38
00:02:57,000 --> 00:03:03,560
Okay. Anyway, there wouldn't be anything for us to

39
00:03:01,280 --> 00:03:05,680
cool if the system wasn't working. So, why don't we talk about what we did on

40
00:03:04,640 --> 00:03:10,200
the refrigeration side? >> When you were going through the initial bit and explaining all the bits and

41
00:03:08,200 --> 00:03:12,520
pieces, spot on. Oh, really? >> You You got You Oh, we got that on

42
00:03:11,800 --> 00:03:17,480
camera. Nice. >> No, abs- absolutely, cuz I was I was impressed, actually. It's like, "Ooh,

43
00:03:15,600 --> 00:03:21,280
this guy You've You've You've done some homework on this."

44
00:03:19,520 --> 00:03:25,040
Yeah, most of it was actually back when I was a teenager, >> [music]

45
00:03:22,520 --> 00:03:30,120
>> because I really, really, really wanted to build a DIY phase change CPU cooler.

46
00:03:27,880 --> 00:03:34,720
So, I learned about the refrigeration cycle, and then ultimately never did it.

47
00:03:33,120 --> 00:03:39,920
And a big part of the reason I never did it was because handling the gases freaks

48
00:03:37,480 --> 00:03:43,480
me the crap out. And as we mentioned in the first video, that was one of the

49
00:03:41,640 --> 00:03:50,120
biggest challenges with this is that it came completely non-charged, so it was

50
00:03:46,800 --> 00:03:52,080
it was empty. Um and we really weren't

51
00:03:50,120 --> 00:03:55,680
sure where or how we could get our hands on the gases. So, you guys have

52
00:03:53,800 --> 00:03:59,640
obviously got it charged up now. Was that a big challenge? For us, not a

53
00:03:57,760 --> 00:04:03,720
problem. We We deal with the cascade systems all the time, so

54
00:04:01,520 --> 00:04:06,480
getting the R508B, the ultra-low temp gas, not an issue. [music]

55
00:04:05,200 --> 00:04:13,280
>> Okay, so it's not one of those ones that's restricted and you're not allowed to buy it anymore. No, it's it's just

56
00:04:11,200 --> 00:04:17,519
not that commonly available. Let's put it that way.

57
00:04:14,920 --> 00:04:21,079
What does that mean? That means you need to have a

58
00:04:18,480 --> 00:04:23,200
refrigeration license, and it's bloody expensive.

59
00:04:22,002 --> 00:04:27,920
>> [sighs] >> You're just going to keep hitting me with that stuff, aren't you? Unf-

60
00:04:25,560 --> 00:04:31,440
Unfortunately, yes. That's the way this project went. What

61
00:04:30,000 --> 00:04:36,240
kind of condition was all the mechanical side of it in? So, like you said,

62
00:04:33,320 --> 00:04:42,840
there's a there's no rust in here, but the question was is how did these age?

63
00:04:38,680 --> 00:04:45,280
And out of these two compressors, it was

64
00:04:42,840 --> 00:04:48,240
this one that was the biggest problem. When we decommissioned it, we put in

65
00:04:46,760 --> 00:04:50,320
nitrogen as a holding charge to basically protect everything, thinking

66
00:04:49,960 --> 00:04:55,240
that >> No rust? No rust. Whoever's going to Whoever wants to buy it or whatever

67
00:04:54,320 --> 00:04:59,080
they're going to do with it, it's going to be safe. They can just turn it on and away it goes.

68
00:04:57,680 --> 00:05:02,160
>> Inert gas, and it's not going to interfere with whatever you want to put in after. That's kind of the idea,

69
00:05:01,840 --> 00:05:06,800
right? >> Yeah, exactly. >> Okay. Problem is

70
00:05:04,920 --> 00:05:09,840
this compressor didn't have any. Like, no gas. So, that's on you guys

71
00:05:08,960 --> 00:05:13,720
then. No. No. There's a leak on there. There's a leak.

72
00:05:13,093 --> 00:05:18,120
>> [laughter] >> I'm not I'm not taking the blame for that one.

73
00:05:16,560 --> 00:05:21,200
Okay, so at some point while it was being stored outside, it sprung

74
00:05:20,520 --> 00:05:27,160
>> It sprung a leak. >> Yeah, it sprung a leak. And so, what ended up happening is that

75
00:05:25,400 --> 00:05:30,400
the oil that's sitting in this compressor becomes contaminated, and

76
00:05:30,123 --> 00:05:35,160
>> [music] >> in order to refurbish it, not only do I

77
00:05:33,480 --> 00:05:38,160
need to take the oil out, but I also need to get rid of all the moisture

78
00:05:36,960 --> 00:05:40,560
that's in there. That was the biggest problem.

79
00:05:42,560 --> 00:05:48,440
Cuz here's the thing, water is also, you

80
00:05:45,960 --> 00:05:53,880
know, a refrigerant in a sense in that it has its own behavior around freezing

81
00:05:51,160 --> 00:05:58,160
and evaporating. And so, if you've got any of that in your other more different

82
00:05:56,120 --> 00:06:01,640
refrigerant, unless it's part of a gas mixture you intended to make, it's

83
00:06:00,259 --> 00:06:06,560
[music] a big problem. This fix was a lot cheaper. This was just a coupler. Right, okay.

84
00:06:04,840 --> 00:06:10,840
>> to put it back together cuz this forms part of the water loop that cools that

85
00:06:08,840 --> 00:06:15,240
low-stage compressor. Got it, okay.

86
00:06:12,680 --> 00:06:19,040
This is such a tiny silver lining on a giant rain cloud. Mhm.

87
00:06:17,560 --> 00:06:23,120
But there is some good news. One of the big challenges we were not looking

88
00:06:21,000 --> 00:06:26,400
forward to was dealing with the control system for this thing. You guys might

89
00:06:24,800 --> 00:06:32,080
remember there was a little touch screen here, and then inside, here, let's crack

90
00:06:28,600 --> 00:06:34,600
this open, there was like a Windows XP

91
00:06:32,080 --> 00:06:40,480
era machine, was it? Well, that's gone. And what are we using

92
00:06:37,520 --> 00:06:46,400
now? So, right now, what we're using is a little Watlow F4 controller. So, this

93
00:06:42,920 --> 00:06:49,200
is primarily what a lot of chambers use,

94
00:06:46,400 --> 00:06:54,400
and we dumbed this thing down a lot. What are you saying?

95
00:06:51,040 --> 00:06:55,940
Ta- Take a really good PC from the 2000s

96
00:06:54,400 --> 00:07:00,160
and throw in a Raspberry Pi instead. [music] Oh, I thought you meant you dumbed down

97
00:06:58,440 --> 00:07:04,800
the simplicity of the interface for the target audience. Well, maybe maybe a

98
00:07:01,960 --> 00:07:09,440
little a little little bit of that, too. Fair enough. I mean, realistically, our

99
00:07:07,080 --> 00:07:13,600
needs are not that complicated. We want to be able to, over the network, I

100
00:07:11,480 --> 00:07:17,640
assume, tell it, "Here's my target temperature, here's how long I want it

101
00:07:15,480 --> 00:07:19,560
there, and here's my next target, and here's when I want it to turn off."

102
00:07:19,040 --> 00:07:25,560
Absolutely. >> And we can do all of that these days with a Raspberry Pi rather than a

103
00:07:22,720 --> 00:07:29,800
full-fledged PC tower. And look at this. There's so much space.

104
00:07:27,920 --> 00:07:33,280
It's free real estate. And all of the other relays and stuff that are in here,

105
00:07:31,320 --> 00:07:36,440
these are all just the originals? Uh yes.

106
00:07:34,480 --> 00:07:40,200
That is so cool. So, do you guys just refurbish and repair these things, or do

107
00:07:38,120 --> 00:07:42,920
you like build them? Uh we don't build them. So, we service them, we repair

108
00:07:41,960 --> 00:07:50,600
them, but we work on a host of other equipment that uses cascade refrigeration. So, if

109
00:07:47,400 --> 00:07:51,680
you had uh a minus 80 freezer, uh if we

110
00:07:50,600 --> 00:07:57,520
If you remember a little thing called COVID and the COVID and the COVID vaccines,

111
00:07:55,320 --> 00:08:01,680
can they need to be stored in at minus 80. Those are the freezers I typically

112
00:07:59,680 --> 00:08:07,480
work on, as well as this. Carmichael does all that laboratory stuff. Cool.

113
00:08:04,760 --> 00:08:11,720
Okay. Can we fire it Can we fire it up then? >> Absolutely. We need to turn on the water

114
00:08:09,520 --> 00:08:15,320
first. Okay. Uh well, I can do that. Yep, turn that one Hold on. Got to turn

115
00:08:13,880 --> 00:08:21,080
on this one, too. Nice, solid. Yep, there we go. Okay. So,

116
00:08:18,200 --> 00:08:24,400
now we've got water coming through, flowing out. Uh-huh, and flowing out to

117
00:08:22,960 --> 00:08:30,560
what? The garden, where at least it can be used by our plants. >> Absolutely.

118
00:08:27,520 --> 00:08:34,640
Is that where it's going? Yes. Okay. You

119
00:08:30,560 --> 00:08:36,760
can tell that this man has experience

120
00:08:34,640 --> 00:08:40,080
working with organizations where the executives don't want to know.

121
00:08:39,420 --> 00:08:45,600
>> [laughter] >> Because once they know, they have to deal with it. I just fix things. Yeah.

122
00:08:44,660 --> 00:08:49,200
[laughter] As far as you're concerned, everything's

123
00:08:47,800 --> 00:08:55,160
fine, sir. Exactly it. All right. So, our cooling

124
00:08:52,120 --> 00:08:57,200
is doing our first stage compressor,

125
00:08:55,160 --> 00:09:00,080
essentially. The the hot side of our first stage compressor loop, right?

126
00:08:58,560 --> 00:09:04,080
Correct. There is There is a small circuit going to the second stage, but for primarily

127
00:09:02,520 --> 00:09:08,440
>> Really? What would the water be doing for the second stage compressor? Because

128
00:09:05,800 --> 00:09:12,000
I thought the second stage's hot side is cooled by the first stage's cold side,

129
00:09:10,680 --> 00:09:18,200
and that's the whole idea. >> Yeah, and you're and you're absolutely right about that, but what this unit has

130
00:09:15,680 --> 00:09:22,520
that's unique is called a desuperheater. So, you end up

131
00:09:19,800 --> 00:09:26,320
You essentially make the second stage compressor run cooler, run more

132
00:09:24,520 --> 00:09:32,160
efficiently, run better. Oh. >> But yeah, primarily the condenser uh for

133
00:09:30,160 --> 00:09:35,280
the first stage does all of the cooling and transfers the heat. Cuz that's me

134
00:09:33,640 --> 00:09:38,640
That's what this chamber is. It pulls heat >> You mean the evaporator.

135
00:09:37,320 --> 00:09:43,440
Depends which system we're talking about.

136
00:09:40,520 --> 00:09:47,200
Wait, right, because it heats and cools. Speaking of which, what kind of a

137
00:09:45,120 --> 00:09:52,560
temperature range can we do with this unit? Because we didn't know that much

138
00:09:49,240 --> 00:09:55,280
about it when we bought it. Um minus 73.

139
00:09:52,560 --> 00:09:55,280
That cold enough for you?

140
00:09:55,640 --> 00:10:00,680
All right. So, the water's on. Yep. The unit's energized.

141
00:09:59,840 --> 00:10:05,760
>> Yep. Do we just press the button? Pretty much. Holy

142
00:10:04,320 --> 00:10:11,920
Elijah, I don't know if you're going to be able to talk me out of us not deploying this.

143
00:10:10,040 --> 00:10:16,362
Yes, I will be able to cuz I'll get you another quote.

144
00:10:14,400 --> 00:10:20,120
It's all good. So, that >> [laughter] >> That's just the That's just the internal

145
00:10:18,480 --> 00:10:24,280
fans. Mhm. And And those are not responsible for

146
00:10:23,040 --> 00:10:29,480
cooling any of the hot sides or anything. >> No. Those just circulate the air through

147
00:10:27,440 --> 00:10:32,440
the what I guess would be an evap Yeah. inside here.

148
00:10:31,000 --> 00:10:39,840
And also just circulate the air in the chamber so you have a constant temperature throughout. Because if you

149
00:10:36,520 --> 00:10:42,120
need an environmental control chamber,

150
00:10:39,840 --> 00:10:45,560
then you obviously care about the consistency of your bloody environmental

151
00:10:44,040 --> 00:10:50,080
control. How cold do you want to go? Cold. Minus

152
00:10:47,920 --> 00:10:54,600
one's fine. Minus one. All right. There we go. Right arrow

153
00:10:52,560 --> 00:10:57,440
turns on. Wow, that simple, huh? That simple.

154
00:10:55,800 --> 00:11:00,160
And then, how long should this take to pull down?

155
00:10:59,240 --> 00:11:05,480
So, the specification The original unit ran

156
00:11:03,640 --> 00:11:12,240
at 100 Yeah. Ran at 1.75° C per minute.

157
00:11:09,720 --> 00:11:16,240
Oh, okay. So, pretty fast. Wow. >> For a chamber that's It's huge. Yeah.

158
00:11:14,280 --> 00:11:22,720
But that was with a load, correct? That was with a 600-lb aluminum load in it.

159
00:11:20,000 --> 00:11:27,800
Oh, so when it's empty, she'll rip. She should, but remember what I what we were

160
00:11:25,360 --> 00:11:32,839
saying about it's almost working? Yeah.

161
00:11:28,920 --> 00:11:34,440
Well, it works, just not as

162
00:11:32,839 --> 00:11:38,680
it was originally designed. It's a little bit slower now. Kind of

163
00:11:36,000 --> 00:11:42,200
like me as I age. As you age. Hey, just so we can have

164
00:11:41,200 --> 00:11:48,000
this conversation where it's a bit quieter, Mhm. why do you think it's slower? Did we not put enough

165
00:11:45,880 --> 00:11:53,280
refrigerant in or like The refrigerant is correct. I know that. The problem is

166
00:11:50,760 --> 00:11:57,200
is the controls. So, because we dumped it down so much,

167
00:11:55,120 --> 00:12:01,480
eventually we can fine-tune it to get it its original performance back, Right.

168
00:11:59,440 --> 00:12:06,440
>> but for for all intents and purposes, it's working at about 80%. Okay, which is

169
00:12:05,360 --> 00:12:11,800
still pretty And it's not going to damage it in any way to run it this way. >> No, it's just not It's just not as

170
00:12:09,880 --> 00:12:15,600
efficient at cooling pulling out the heat. Got it. Okay.

171
00:12:14,160 --> 00:12:21,480
I'm good with that. Let's go see what kind of progress we've made while we've been standing here. Wow, we got we got

172
00:12:18,600 --> 00:12:24,440
better than our 1°. I mean, given the size of the things that we would ever

173
00:12:23,360 --> 00:12:30,240
put in something like this, that's actually perfectly fast [music] for us.

174
00:12:28,200 --> 00:12:31,360
Want to go in it, Elijah? It's really loud inside.

175
00:12:31,293 --> 00:12:37,440
>> [music] >> Double up the hearing protection? We might have to. >> decibels last time we measured it.

176
00:12:40,680 --> 00:12:44,920
I actually can't hear you. >> I didn't talk. I was

177
00:12:46,440 --> 00:12:51,640
Do you want to Do you want a jacket? Like LCD store or something so it's not

178
00:12:50,080 --> 00:12:56,720
Oh, yeah, yeah, yeah, yeah. Yeah, okay. That's our new one. [music] Yeah, buddy. LCDstore.com

179
00:12:59,000 --> 00:13:01,680
What can I say?

180
00:13:04,160 --> 00:13:07,839
Oops. Oh my god.

181
00:13:08,560 --> 00:13:16,800
So cold. It's fine. It's something like zero.

182
00:13:13,640 --> 00:13:19,920
This is Canadian summer, baby.

183
00:13:16,800 --> 00:13:19,920
Okay, close this thing.

184
00:13:19,960 --> 00:13:25,760
Let's see how long it stays inside here.

185
00:13:23,920 --> 00:13:28,560
Okay? It's down 5°.

186
00:13:29,160 --> 00:13:34,839
It definitely goes down quicker.

187
00:13:32,440 --> 00:13:34,839
Down 10.

188
00:13:46,760 --> 00:13:53,920
It's very dry. Yeah.

189
00:13:50,680 --> 00:13:55,920
So, it's not that bad.

190
00:13:53,920 --> 00:13:59,800
It's not great, though. Do you want to go lower?

191
00:13:57,560 --> 00:13:59,800
Okay.

192
00:14:06,440 --> 00:14:10,440
My My nose is running now.

193
00:14:15,680 --> 00:14:21,839
There we go. Just set it for minus 40, so

194
00:14:18,760 --> 00:14:25,079
it'll get a bit frosty now. My mustache

195
00:14:21,839 --> 00:14:26,560
is starting to ice. My nose is.

196
00:14:25,079 --> 00:14:32,920
Okay. Are you done? I'm done. You're done?

197
00:14:29,680 --> 00:14:36,240
All right, we'll call it. WE'LL CALL IT.

198
00:14:32,920 --> 00:14:36,240
OH, THAT'S SO NICE.

199
00:14:36,400 --> 00:14:42,720
WOO! WELL, SHE WORKS.

200
00:14:40,280 --> 00:14:47,839
What did we make it to? Minus 22. Minus 22, which Okay, with how fast the air

201
00:14:46,320 --> 00:14:53,120
was circulating in there, I wonder what the wind chill was on that. >> Yeah, it was really bad.

202
00:14:50,920 --> 00:14:57,360
Freaking cold. I mean, my nose started to run about halfway,

203
00:14:55,520 --> 00:15:01,720
and then the last minute or so, I could feel my nose hairs freezing. And I was

204
00:14:59,760 --> 00:15:03,959
like, this is very uncomfortable. That was so fun, though.

205
00:15:03,255 --> 00:15:08,320
>> [laughter] >> But it freaking works. >> It's real And we that's not even as cold

206
00:15:06,800 --> 00:15:12,920
as it can go. Can we see how much we can push it? >> Yeah, we should let it keep going. >> to minus 40, so let's

207
00:15:11,800 --> 00:15:18,160
Well, so let's let it keep going. In the meantime, you asked me a question while we were in there, and the audio was

208
00:15:16,320 --> 00:15:23,640
obviously not usable. Like, what would we use something like this for?

209
00:15:19,360 --> 00:15:23,640
>> Yeah. And the answer is

210
00:15:23,720 --> 00:15:29,240
us not really anything. Our small chamber can accommodate what is

211
00:15:27,560 --> 00:15:33,920
realistically the largest thing that we would test, which is a desktop PC. But

212
00:15:32,760 --> 00:15:38,440
what these are used for in a more industrial environment is validation of

213
00:15:36,720 --> 00:15:43,600
Apparently, this one's former life was validating solar panels. So, really it

214
00:15:40,560 --> 00:15:46,000
would be for environmental validation of

215
00:15:43,600 --> 00:15:50,480
outdoor-rated equipment Got it. >> that could be deployed anywhere from

216
00:15:48,240 --> 00:15:55,000
Arizona to Antarctica. Let's go take a look at -40. Remember how I was how I

217
00:15:52,920 --> 00:15:59,959
was telling you we move energy? Yeah. Put your hand on here. That's the water

218
00:15:56,480 --> 00:16:02,480
inlet. Put your hand on here.

219
00:15:59,959 --> 00:16:04,400
That is a huge delta. Yeah. That's crazy.

220
00:16:03,320 --> 00:16:11,400
>> Yeah. This is warm water coming out of here.

221
00:16:08,160 --> 00:16:11,400
Can we throw the panels on right now?

222
00:16:12,800 --> 00:16:19,160
>> It's still really loud. >> Oh, yeah. Yeah, I know. It's not not at

223
00:16:16,800 --> 00:16:22,480
all conceivable for an open workspace like you guys have. It is a lot better,

224
00:16:21,320 --> 00:16:26,160
though. It is.

225
00:16:24,680 --> 00:16:31,320
Stop. I'm just thinking. We haven't even gone

226
00:16:28,640 --> 00:16:35,680
over why it would have cost $250,000 to keep it permanently yet. Okay, we should

227
00:16:33,280 --> 00:16:40,880
probably talk about that. But first, I want to experience minus 48° C.

228
00:16:41,880 --> 00:16:44,160
Oh, yeah.

229
00:16:45,600 --> 00:16:47,720
Okay.

230
00:16:57,839 --> 00:17:05,079
Woo! Woo! Oh, man.

231
00:17:01,720 --> 00:17:05,079
That's chilly.

232
00:17:05,160 --> 00:17:08,160
WOW.

233
00:17:09,240 --> 00:17:16,480
OH my god, you are blue. Chilly, boys.

234
00:17:13,880 --> 00:17:22,240
I'm Canadian, but I'm like southwestern Canadian. Doesn't get that cold here. I

235
00:17:18,360 --> 00:17:23,800
have never [music] experienced minus 50.

236
00:17:22,240 --> 00:17:27,439
That's crazy. I've never seen my breath come out like

237
00:17:25,520 --> 00:17:31,520
that. Like, immediately my mustache started to freeze. That All right.

238
00:17:30,632 --> 00:17:37,182
>> [music] >> Let's talk about the challenges of keeping it. There are several reasons we

239
00:17:35,640 --> 00:17:43,000
can't run this long-term. Starting [music] with probably the most expensive, as you heard, it was too loud

240
00:17:40,760 --> 00:17:47,662
to operate out in the open like this. So, we would need to build a up-to-code

241
00:17:45,560 --> 00:17:51,800
room to house this thing. That means [music] plumbing in case it leaks, fire

242
00:17:50,000 --> 00:17:56,280
suppression in case it blows up, you know, noise treatment and electrical and

243
00:17:54,200 --> 00:18:00,840
so much more. And it would have to be big enough that it can not only fit in

244
00:17:58,240 --> 00:18:05,480
it, but service technicians who would need to come at least annually need to

245
00:18:03,080 --> 00:18:08,622
be able to access every side of the machine in order to crawl around and

246
00:18:07,320 --> 00:18:12,800
find out what the >> [music] >> mystery piddle stain is. That's right.

247
00:18:11,200 --> 00:18:16,840
With that said, that doesn't sound like a quarter million dollars.

248
00:18:14,920 --> 00:18:21,120
You're right. We would actually need to reinforce the

249
00:18:18,800 --> 00:18:26,307
roof because for every energy unit of cool or heat that you put inside of this

250
00:18:23,960 --> 00:18:29,320
chamber, you need to dissipate it, >> [music] >> you know, somewhere outside of this

251
00:18:27,760 --> 00:18:34,400
chamber, preferably outside. >> So, that's where like our cooling tower might come in, except that

252
00:18:33,512 --> 00:18:39,760
>> [laughter] >> we're talking about up to 200,000 BTU an

253
00:18:37,640 --> 00:18:44,240
hour. So, that cooling tower ain't going to do it, and even something quite a bit

254
00:18:41,800 --> 00:18:47,360
larger might not do it. No. And I really don't want to reinforce

255
00:18:45,560 --> 00:18:51,280
the roof again. We already had to do it once in order to air-condition the

256
00:18:48,640 --> 00:18:53,818
warehouse, and it was terrible. It took so long.

257
00:18:51,960 --> 00:18:57,840
>> However, No. >> [music] >> No, we're not doing it.

258
00:18:55,919 --> 00:19:01,600
Okay, that's fair. But that actually doesn't mean that this unit's story is

259
00:18:59,760 --> 00:19:04,840
over. The quote from Carmichael, as I alluded to earlier, was extremely

260
00:19:03,280 --> 00:19:08,080
generous considering the incredible amount of work they had to do here >> [music]

261
00:19:06,280 --> 00:19:11,760
>> thanks to some extra stuff they had lying around and also just wanting to be

262
00:19:10,080 --> 00:19:17,480
turbo bros. [music] So, we're going to have them linked down below for your refrigeration and heating needs. Um and

263
00:19:15,520 --> 00:19:22,919
that cost savings they gave us matters because now this thing is in pretty much

264
00:19:20,720 --> 00:19:26,159
fully functional, ready to be integrated condition.

265
00:19:24,120 --> 00:19:30,960
It's a pretty nice system, and we'd be happy to let it go for what we paid plus

266
00:19:28,320 --> 00:19:35,040
transport. You will have to capture the gas and regas it, but that cost is a

267
00:19:33,840 --> 00:19:38,760
fraction of what you'd spend on a machine of this size and class brand
