Cheers from Down Unda.
Have a recent R-134a chiller only a few old that has several very small leaks at the tubes expansion joint at the tube sheet, both ends and random. Not over or under rolled, no erosion. Water flows and velocities are ok within 10% design. Water cleanliness is ok. Tubes are standard 90/10 cupra nickel marine use. :confused:
Regards Blackers
