I just read the paper, thanks.
The conclusion was that the degradaton was insignificant, inconclusive and that the testing would need to be run up to 10,000hours for a more accurate determination to be made.
I have been running a pelt chiller for around 14 months, 12~16 hours per day, 5~6 days a week. ( around 5,000 hours) Using a vpc controller, I am still using the same pelts and to date there have been no problems.
