How much Glycol? And those 56c faced pumps are cute little guys.
No idea about that system. (the one in the photos above.)
My main transmitter is air-cooled, and we just pump raw chiller water from the roof (filtered) through the six aircon units which service it.
I have a closed-loop glycol system on my aux transmitter, and while I've never measured the exact capacity, I know that it can be completely filled with two 55 gallon drums of pre-mix, with about 1/2 drum left over. For perspective, it uses only one of the pump modules pictured above, and has two air/water heat exchangers each about 6 foot cubed. These were custom-built units that fit into the space which four windows used to occupy on the 93'rd floor of the John Hancock building, before we removed them. (You'd be surprised by how much bureaucratic red-tape is involved with smashing out a window from the top of a downtown skyscraper. They have to shut down the streets, pay about 40 police officers overtime, have fire and EMS standing by, etc... It's a pain.)
This arrangement is of unending annoyance to me. At Sears, I have an air-cooled transmitter which I cool with air from HVAC units cooled by building water. At Hancock, I have a water-cooled transmitter which I cool with two large radiators which take in outside air.
You got that? The air-cooled transmitter is cooled by water, and the water-cooled transmitter is cooled by air.
I can't make this **** up. My predecessor seemed to love making everything as complex as possible.
I am going to fix this. It's going to cost a shitload of money, and probably take about two years, but I AM going to fix this insanity.

Haha, yes it is.
To be clear, I am not responsible for these pumps, I just get to walk past them on a regular basis. This is a portion of the HVAC system located on the 104th / 105th floor of Sears Tower, where four of our ENG receive antennas are located:

Now that's my type of cooling system. How do i get paid more and be the kid in charge of big stuff like that? I really did apply to do the maintenance thing on radio towers, never got a call back. I guess heading million dollar capital expenses makes me a bit overqualified. Or perhaps it was just my autism, i'm actually unsure.
I have a sweet photo of me plumbing in offset rolling 90s on our new(then) 226 ton Trane chillers. But i can't find it and it must be on my work PC.
This picture of the most reliable, durable, and badass drill i have ever laid hands on will have to suffice.

I say this based on personal experience: To get a job with a professional tower crew, you have to be clinically insane, and also an escaped felon.
Seriously, those guys scare me. I assume that the only reason why they have not murdered me for fun is that I pay them well, and my checks never bounce.
To be clear: professional tower climbers are a seriously disturbed breed. I have honestly never worked with a single one who didn't have prison tattoos, and that includes the foremen and supers.

Uh yeah, we all grew up inner city.* We have a questionable past and unrelatable tattoos. Spelling is a side quest for us.
* i spent 3 years at Miller where they taught in Arabic in my early years 1-3rd grade. It really is a miracle can even communicate day to day. (thank god for spell check)
Lived just east of woodmere, commuted / walked / transported to Dearborn because it was less "colored" than where i was.
Ever wonder if a sufficiently advanced robot can feel loneliness and fear?
I like to think that some fiendishly evil software engineer, many years ago, saw an extra few k of unallocated storage and decided to provide an affordance to emulate them.

Should have followed it up with "...damn you for abandoning me in this cold and desolate place"
