Nigel,
I think you are right to be cautious about pressures in a Brazed Plate HX. Pressure information is readily available from selection literature on the manufacturer's web site.
But I don't think that Brazed Plate HXs would be a problem, regarding friction losses... they're pretty well designed.
The main impediment I see is cost... I've been able to locate some pretty good deals on ebay.
