During the 1980's this would have been for testing in the European Transonic Wind-tunnel Programme's cryogenic testing. Because of this the building has become known as the 3x3 (0.3metre x 0.3metre x 1.5metre) Laboratory due to the sizing of the Cryogenic ducting.
Discovered a whole bunch of photos I took of Tone Mills Dyehouse on my 30mm prime back in 2015 which I don't think ever got posted anywhere, these were some of my favourite shots I've got of the place over my numerous visits since 2012. It was always such a photogenic place even with the degredation and damage it took over time.

I visited at the end of August 2022 I believe, not sure if it is still accessible. I believe it got sealed at some point towards the end of last year, but not sure of its status of it now. Hope that helps somewhat!
