Paul:
Hopefully they have improved their design with respect to thermal cycling. We
used to have a couple of these made by Harrison Radiator for regenerative cycle
on GE Frame 3 turbines. Would have about 50-100 starts (thermal cycles) per
year. After about 5-6 years, the brazed joints would start cracking and cycle
efficiency would be out the window.
Agree with the other comments you had - good efficiency, great on physical size, just hope they have worked on plate design for fatigue resistance.

Benefits of Brazed-Plate Heat Exchangers
<<Over the past decade a new technology has been taking hold on the US market. It offers significant advantages over the standard shell and tube heat exchanger, and it is flexible so it can be used in a variety of applications. Known as Plate Heat Exchangers, these units are significantly smaller in size, and are a more efficient option than their counterparts. Overall efficiency goes beyond the ability to transfer BTU's. Plate Heat Exchanger technology is not new, having been around for about 60 years. European companies have successfully used Plate Heat Exchangers in many different applications. There the technology has been refined, and the results are such now that many US industries are taking a new fresh look.>>
