World Trade Center had 49,000 Tons of YORK Cooling
Neat Comment about The Famous YORK Flex Coupling

I received this e-mail on Tuesday from Gary Wilson, as a neat comment to my post on Monday:
You forgot to mention The Famous YORK Flex Coupling appearing in the painting! I was lucky enough to pick up one of your YorksPast calling cards at the Family History Conference in Las Vegas last year. I occasionally check your family history tips, however what really hooked me was the YORK Air Conditioning history.
As a young mechanic in the 70s, the company I worked for in California sent me to York, PA for some training at the YORK Institute building attached to the YORK Headquarters. The instructor would always emphasize FAMOUS when talking about the YORK Flex Coupling. Attached is a photo of a used YORK Flex Coupling, presently for sale on eBay.
Following the training, we toured some YORK installations in New York City. I’ll always remember seeing the massive YORK Equipment within the World Trade Center.
Gary Wilson is correct; I should have pointed out the YORK Flex Coupling parts, that Thompson clearly included within the painting. The coupling was famous for simplicity of design. At the beginning of this post, I’ve cut out sections of the painting, to show their relative arrangement within a YORK Multistage Centrifugal Compressor; i.e. the type of compressor that was used within the World Trade Center. I also rotated the photo of the used YORK Flex Coupling, to match the orientation appearing in the 1969 painting by Kenneth J. Thompson.

As Gary Wilson pointed out, YORK supplied the air conditioning for the Twin Towers of the World Trade Center in New York City. In 1968 it was the single largest water-cooled air conditioning system in the world. Seven huge YORK Multistage Centrifugal Compressors, each with a 7,000 Ton capacity, supplied the 49,000 Tons of cooling required by the whole World Trade Center complex.
