We experienced a catastrophic failure of a brazed aluminum heat exchanger (blowout of cover). The vendor report on the failure cites the reason for the failure as due to frequent (approx 100) excursions in temperature where temperature difference between the warm stream and cold stream exceeded 30 C in the life of the exchanger. The exchanger was new and put in service for only about 2 months.
My questions:
1) Does the vendor's reason for the failure seem plausible/credible?
2) Is it possible to get an independent third party to review the vendor's design of the exchanger and vendor's report on the failure?
We suspect the exchanger design may be faulty.
