The Cat/Ariel 3516 arctic package was custom made by Universal Compression in Calgary in 2002 for an application in Price, UT.  It was moved to Flat Rock, UT in 2005 and was released from there in 2015.  The unit is currently stored in Evertson's yard in Kimbal, NE.  A new engine was installed in late 2014 and the unit only ran several months before it was released.

Photos, compressor runs/curves and the P&ID drawings are included in the data package (click on the Documents tab).
