I'm just guessing, but they look like chill water system pumps, but the piping is different from the ones I've been involved with.
So....?
Upon closer inspection of the photos, and another sip of coffee, I now believe they are large compressors.
@Deeper Texan is on target.
Those are Centrifugal compressors for Chiller Water Systems.
The giant one with me standing next to it is a late 80’s 1660-ton (19,920,000 BTU/hr) chiller at Columbia University (but I heard it’s been removed by now for a new model). The first two are 450- and 320-ton respectively.
I am currently doing maintenance on a trio of 2500-ton Duplex Centrifugal chillers.
Duplex meaning two 1250-ton compressors on one chiller.
In order to maybe get a clearer reference on the size of these, 1 ton of cooling capacity = 1 horsepower of energy.
Panel-side, compressors are obscured by the Adaptive Frequency Drives
you can just make out the compressors sitting on top…
Maintenance is the worst part…I did two out of three and I’m ready to quit and become a YouTuber…

If they are anything like the ones I worked on, they have been installed in areas, just big enough to fit, but not big enough to access. But yours are much cleaner, than what I dealt with. I usually had two inches of oil, on the floor.
These have also been “shoehorned” in. There are plenty of pipes and electrical conduits overhead that prevent an easy compressor disassembly. The MER is also pretty dumpy by my standards…
The absolute BEST installation I have witnessed was at a major international airport. Eight 2000-ton duplex chillers in a line with a 7-ton capacity overhead Crane with electric hoist. One could really get spoiled in that job…
This was the NICEST mechanical room in all of NYC.
(Weird how these postings came out…)
I've been retired since 2010, but I was a truck driver and then a diesel mechanic.
