In a recent e-newsletter, Moore Industries, North Hills, Calif., gave readers an update on the company’s NCS NET concentrator system that has been the subject of a seven-year Highly Accelerated Life Test, which has subjected the unit to extreme heat. The company reports “the unit is performing remarkably well” and might outlive the oven being used for the test.

According Moore Industries, “The NCS unit has been subjected to around-the-clock temperatures of 194°F (90°C) since May 2007 and — with the exception of the label browning and some other minor repairs — it has been performing flawlessly ever since. We recently had to replace the electrolytic capacitors on the unit, but this was only after they exceeded their expected operational life.”
