What are some of the larget Central Plants You have Seen??
This is a question for all those who work as building engineers or service larger equipment.
What are some of the largest Central Plants You have Seen, during your years in this industry?? More Specifically, what are some of the largest Central Plants for Comfort air conditioning. We all know that many factories/industrial facilities have large chiller systems, however the largest system specifically designed for comfort air conditioning was the former World Trade Center in NYC. That plant had 7- 7000 ton York Chillers. 49,000 tons of cooling capacity.
Has anybody here ever seen anything that can come close to this?? What was the tonnage?? What building was it in?? Were they doing cooling only, or did they also have heating (Boilers)??
It always great to hear the experiences of others!
PS: I've attached a picture from the WTC Plant
Ohio State has a very impressive power plant...
CHILLED WATER PLANT
Two 2,000 ton turbine-driven centrifugal chillers, five 2,000 ton dual compressor electric centrifugal chillers, two 775 ton electric centrifugal chillers, a 450 ton electric rotary screw chiller, nineteen cooling towers, and a plate-and-frame heat exchanger have been installed to supply some of the campus from a central chilled water system. Thirty inch mains supply chilled water to some central campus buildings.
Just about a million lbs/hr steam capacity.
I have a picture of the OSU chiller plant you're talking about as the wallpaper on my laptop. I've seen pictures of data centers with 20 York centrifugals lined up in a row.

One of the biggest ones I work at occasionally is a 13,000 ton plant for a local university that consists of a 1500t Trane CVHB, a 3000t Trane CDHF Duplex, (2) 2000t Carrier 17FAs, (1) 3000t York Turbomaster, and (2) 750t York YTs. They have numerous other smaller plants with Trane Duplexes in the 7,500 to 8,000 ton range.
I've got a lot of pictures I'll post later.

It's very impressive. I got to see it go through it's stages of being built from a steel structure. The finishing touches are being preformed at this point.

Has anybody worked at/toured Con Edison Steam??? Now THAT plant would be interesting to visit. I've heard they have boilers 7 stories tall!!
Anybody ever seen anything like this?
Thanks again for all the imput!
The hospital I work at has got about 8000 tons, but its situated in two different plants. Probably going to be downsized in the next year or so though, removing a couple 750T tranes and replacing them with a single 950T.
Thanks for the replies. I know that the World Trade Center plant, with 49,000 tons is extreme. But, how large of a tonnage capacity is considered large in a chiller plant??
Any other interesting examples would be great!
Kennedy Airport has the largest absorber chiller plant around also handled by York.WTC contract was a easy Million $ anually with a tech 40hrs on site from the day it was installed,and he retired the thursday before the attacks.
Did the old towers have 1 plant for both?
Mark Beiser saw the main chilled water plant for Indy's district cooling. I forgot what all he said was in there. The system has 2 more elsewhere.
I believe the WTC plant provided chilled water for both 110 story towers, the smaller buildings located in the complex, the train station, and the shopping mall. Despite the square footage that had to be cooled, I would bet that they still had quite a bit of redundancy. The plant used water from the Hudson River, as condenser water.

Thanks for sharing your experiences. It’s always great to hear about those HUGE systems!!
Thanks for the replies! So, did anyone ever actually get to tour the original WTC Plant??
When I worked at Honeywell we studied the engineering/fire/security systems for the building via a film made for this purpose. That film, if still around, would be a good thing to have.

And that is why, according to the film, that many machine rooms had to be built. He also described the common problem of flushing a comode on the top floor and letting it free fall to the basement.............
